UV Photochromic Printing: a new printing option for bags UV photochromic printing is a special printing method which applies Sunlight or UV (ultraviolet) light properties to realize color change effect of printed matters.   Principle of Photochromic Color Change Ultraviolet light is invisible light in the violet range of the spectrum in the electromagnetic spectrum. The key point of UV photochromic printing is the application of special photochromic inks. Such inks include photochromic materials which have chemical reaction capabilities. Under the effect of the ultraviolet ray, the molecular structure of the photochromic matter in the ink varies so that a color change is achieved.   After printing photochromic ink, it needs to be coated with UV after printing, but the printing process is the same as that of ordinary ink. During the curing process, the ultraviolet light emitted by the UV lamp activates the photochromic substances in the ink, priming them for a color change. Once the printed material is later exposed to natural sunlight or a specific ultraviolet light source, the color-changing effect appears.    Because of photochromic color principle (the rate of discoloration will also change depending on the environment that the product is used.) Factors including light, application environment etc. may have a direct effect on life span depending on the product being used.   Application environment: Photochromic substances are easily oxidized by oxygen in the air. The photochromic material which has resistivity to the oxidation is effective to maintain the performance for a long time. Special processed or antioxidative type of photochromic ink has longer life than a regular ink. The life of the photochromic content is also influenced by temperature and humidity. Chemical reactions are accelerated by high temperatures and high humidity that cause the colouring of the photochromic materials to age. For example, the duration of stability of the photochromic materials may be shorter in humid tropical zones as compred to dry moderate zones.   Light Intensity: High intensity of ultraviolet light, the photochromic chemicals reaction speed is faster, the chemical process will more quickly, and aging of photochromic lens. For instance, when exposed to the natural sunlight, sometimes the service life of photochromic materials is very short. Their life span is relatively long since they are in the indoor environment with lower light intensity.   Usage Frequency: Usage frequency is the frequency with which the photochromic materials are actuated (ie, exposed to the ultraviolet or particular light source) in a given period of time. The photochromic materials are gradually damaged by the exposure of UV. Any single exposure results in some tiny alteration in molecular structure, and these miniscule changes add up over time and can be observed as deterioration in performance. The service life of photochromatic materials is extremely short at high frequency of use. One example of this is that a product which is used ten times per day with UV exposure, may have a photochromic life of a few months, while a product used once a day may last 1-2 years.   When this special principle of photosensitive color change is applied to photochromic printing technology, the application prospect is very broad. More directly, it introduces a new visual experience and surprises to bags, fashion and creativity and brings new visual effects to the product. For instance, patterns printed with UV photochromic inks on T-shirts, tote bags, backpacks, phone cases and other items can change their color under sunlight, which makes the product more fun and attractive. It is to be noted that the color switch effect is adjustable and difficult to be replicated by others, so it is very reliable to product anti-counterfeiting. As long as it continues to develop technologically, and becomes cheaper to use, it is just going to spread into more areas.   Special note at the end, it should be noted that this printing process has to be done in particular conditions e.g. not to be disturbed by natural light etc. Proper drying temperature and drying time can avoid damages of the photochromic substances during printing, which contributes to the effect of color change to be precise and stable. Similar premature aging of the photochromic substances can occur when the drying condition is such that the drying temperature is unduly high or the drying time is unduly long.     Author        

One buzz, and the entire world presses against your face. On the subway, at the dinner table, even at 3 a.m. in bed, that pale screen-light acts like an invisible umbilical cord, tethering us to the cloud. Every absent-minded swipe quietly uploads your coordinates; every “Allow Location” can turn today’s footsteps into tomorrow’s data map, sold to strangers. The awkward truth? Most countries still haven’t written the rules. So we’re left with a private, almost absurd choice: step into a signal-proof cage or stay naked in the open—security or convenience, rarely both.     For 32 years we’ve done one thing: make bags that simply work better. From the very first stitch, “easy to use” has been our non-negotiable. Today we’re adding a fresh layer to that ease—security. Signals flit around inside a bag; we make sure they never make it out. Below, we break it down step by step: how a wafer-thin shielding fabric slips unnoticed into wallets, backpacks, briefcases, even an ordinary grocery tote, turning every pocket into a dead zone where phones go silent and privacy stays put.   Back then, cutting off radio waves meant wheeling in the hulking metal cages locked away in military bunkers. Now it only takes a strip of cloth. We took the RF shielding once sealed inside spacecraft and operating theaters and wove it straight into the fibers: a whisper-thin copper-ion mist wraps every yarn, while silver filaments thread through at micron-level precision. What rolls off the loom is a supple “soft armor” you can fold, cut, even toss in the wash. Stitch it into a pocket and you’ve got a pocket-sized Faraday cage: the moment a phone slips inside, it goes mute; prying signals bounce off like they’ve hit a wall. One zip, and the digital world falls silent.   Think of signal-blocking fabric as an “invisible lock.” It can be stitched into almost any bag, sealing out RFID skimmers, GPS trackers, and Bluetooth sniffers in one move. More than a data firewall, it’s a Do-Not-Disturb sign you can carry. Drop your phone, earbuds, or smartwatch into the shielded pocket and Wi-Fi and cellular vanish instantly—meetings, reading sessions, or playtime with the kids go uninterrupted. On the road, tuck your camera and spare phone into the shielded compartment of your carry-on: no leaks, just a few blissfully offline hours to watch the scenery instead of the screen. The same goes for wallets and passport sleeves—snap the shield shut before security, and both your data and your mind stay quiet.   Here’s the complete run-down of signal-blocking fabric in everyday bags： 1. Wallet & Passport SleeveSlip a 0.2 mm shielding layer between the billfold and card slots. Card readers can’t see your chips; slide your passport in the same pocket and no one can skim it while you queue at immigration.   2. Handbag / ToteAdd a removable “signal cocoon” in the main compartment. Drop the phone in—airplane mode without toggling a switch. Pull it out and bars pop back up instantly.   3. BackpackLine the laptop sleeve on all four sides. A 15.6" notebook disappears from Wi-Fi and Bluetooth the moment the zipper closes.   4. Travel Bag / Carry-on Sew a shielded stash pocket under the top lid for passport, backup phone, and camera cards. Even the airport “sniffer dogs” of RF leave empty-handed.   5. Briefcase / Document CaseKeep the outer face premium leather or Oxford cloth; back it with a full sheet of shielding fabric. Contracts, USB drives, and encrypted dongles sit in a silent vault no matter who’s running a spectrum recorder in the conference room.   6. Gym DuffelTuck an 18 × 10 cm “watch hut” above the shoe tunnel. Drop your smartwatch and earbuds in before you hit the treadmill—notifications stay outside the squat rack.   7. Student Backpack / Pencil PouchTurn the classic roll-top pencil case into a signal roll-cage. Phone goes in, fabric rolls shut, and the ringer never rings during first period.   8. Medical & Scientific Transit BagsUse heavy-duty metal-fiber cloth rated ≥90 dB to create soft Faraday crates of any size. Portable ultrasound probes or RFID-tagged blood samples travel in total radio silence, immune to data bleed or malicious pings.   A piece of fabric that looks utterly ordinary is quietly stitching military-grade EMI shielding into everyday life. Wallets, passport sleeves, 32-inch spinner cases—even the tiny schoolbag on a child’s back or a robot pack loaded with AI modules—are no longer just containers, they’re pocket-sized quiet zones. We’re not out to kill signals; we just want them to appear only where they’re supposed to. Safety and convenience, finally in the same stitch. To ODM/OEM partners and independent designers: let’s cut this fabric into new stories together, and bring the smart-security bag to everyone.   Author        

In today’s highly advanced information technology era, are you concerned about your digital privacy?   Many things have two sides. For example, with just a simple tap of a small card, you can complete a payment without worrying about how the money flows into the recipient’s account. But have you ever worried that malicious people might exploit this technology? Yes, I’m talking about electronic card fraud—while these convenient contactless payments make life easier, they also create opportunities for ill-intentioned individuals. Another example is Apple’s AirTag, a small tracking device that works with your phone’s location system to let you know the whereabouts of yourself or your belongings at any time. This helps you easily find lost items by opening a map. But the question is—are you worried that someone might use this technology to track you without your consent?   With the development of wireless signal technology, the need for effective electromagnetic shielding has become more urgent than ever. Protecting data and personal privacy is a pressing demand, driving rapid growth in this market.   Advanced Copper-Nickel Coating Technology The cutting-edge signal jamming fabric represents a breakthrough in electromagnetic interference (EMI) shielding technology. It is thin and bendable, but it can block more than 99% of radio frequency signals (mobile phones, Wi-Fi, Bluetooth, RFID, NFC, UWB, AirTag, etc.). At the same time, it does not absorb moisture, does not fade, and can withstand wear for up to 100,000 times. Signal jamming fabric is a copper-nickel coated fiber combination material. It is a composite conductive material formed by depositing copper and nickel layers on the fiber surface in sequence through vacuum deposition, which is currently the most advanced process on the market. In simple terms, it is a flexible metal cloth with a copper-nickel alloy cortex "growing" on the fiber surface. It is light and tough, and can block electromagnetic waves like a metal shell. Vacuum coating gives this material enhanced high-temperature resistance and more stable shielding performance. The electroless plating process used in manufacturing allows for coating every single fiber with materials like nickel, which offers excellent corrosion resistance and high shielding capacity. This manufacturing approach ensures uniform coverage and consistent performance across the entire fabric surface. Superior Performance Characteristics Its performance advantages are mainly reflected in the following aspects:   Conductive and Shielding Performance High conductivity: The copper layer provides an excellent electron conduction channel, and the nickel layer enhances stability. The synergistic effect of the two can significantly improve the overall conductivity of the material. Cu provides high conductivity, Ni provides magnetic permeability and anti-oxidation layer, forming Cu₃.₈Ni alloy lattice, which has both conductivity and magnetic shielding. Electromagnetic shielding effectiveness: In the frequency band of 0.15 MHz–20 GHz, the shielding effectiveness can reach 50–100 dB, which is suitable for electromagnetic sensitive environments such as radar, communication equipment, and data centers. Copper-nickel alloys like C77000 are specifically chosen for EMI shielding applications due to their inherent corrosion resistance properties, making them ideal for long-term reliability in various environmental conditions.   Material Bonding and Performance The copper-nickel alloy layer forms a metal bond with the fiber, and is covered with an amorphous Ni-P (83.98% Ni, 16.02% P) protective layer to further improve corrosion resistance and oxidation resistance. Coating bonding strength: The tape peeling rate is < 0.4%, there is no crack after 20,000 bends, and the wear resistance is 4–5.   Environmental Protection and Compliance Compliant with RoHS, REACH, MIL-STD-461, GJB 6190 Military-grade fabrics are certified to standards like MIL STD 188-125 and IEEE 299-2006, ensuring they meet the stringent requirements for defense and critical infrastructure applications.   Heat Resistance and Corrosion Resistance Nickel layer anti-oxidation: The nickel layer covers the surface of the copper layer, effectively preventing copper oxidation and improving the stability and service life of the material in high temperature or humid environments   Process Compatibility and Controllability Controllable vacuum deposition process parameters: A uniform and dense coating can be obtained under conditions such as temperature 60°C, pH=12, and time 2–5 minutes Strong scalability: Laser cutting, ultrasonic welding, sewing, hot pressing, weaving, lamination and other composite processing methods are available   Market Applications and Industry Adoption EMF metalized fabrics infused with elements such as copper, silver, nickel, and stainless steel are engineered for industrial-grade electromagnetic shielding while ensuring durability and versatility. The versatility of these materials has led to widespread adoption across multiple industries.   Typical Application Scenarios Application areas Example uses Electromagnetic shielding Shielded curtains, military tents, data center shielding cloth Wearable and flexible electronics Smart heating clothing, EMC gloves Conductive fabrics Antistatic clothing, conductive sewing thread, flexible circuits Aerospace Satellite electromagnetic shielding layer, engine thermal insulation components In an increasingly connected world, Faraday bags have gained popularity among law enforcement forensic investigators, tech enthusiasts, professionals, and privacy advocates, reflecting the growing awareness of digital privacy concerns. Based on different product requirements, materials can be further customized, such as controlling the copper-nickel thickness ratio, substrate selection, shielding frequency band optimization, and adjusting the plating process parameters based on specific application requirements.   Consumer Applications: Transforming Everyday Bags Back to our bag field, signal jamming fabric can be used in a wide range of scenarios:   1. Digital Security Bags - "One Bag" Invisibility Solution A layer of signal jamming fabric is lined inside the bag to make a flip-open hidden pocket. For meetings, exams, cinemas, theaters, etc., put your mobile phone/earphones/car keys in it to instantly shield all wireless signals to prevent interference, positioning, eavesdropping, and recording. No need to turn off or turn on the devices, just use and put it away.Companies like SLNT create Faraday bags trusted by Google and the US Army that effortlessly fit into daily routines for continuous data protection, demonstrating the mainstream adoption of this technology.   2. Anti-Theft Card Protection The inner compartment or inner pocket of the wallet or backpack that holds credit cards/passports is replaced with signal jamming fabric as an interlayer to prevent RFID theft and remote scanning. Thinner than traditional aluminum foil interlayer, resistant to bending and folding 20,000 times without cracking. Similar to how booster bags lined with aluminum foil act as Faraday cages, specialized containers are used to resist RFID skimming, but modern fabrics offer superior durability and flexibility.   3. Anti-Tracking Protection - Neutralizing AirTag Surveillance Add a layer of signal jamming fabric in the computer compartment or camera compartment, put in AirTag or smart luggage tag to shield its broadcast signal and avoid malicious tracking. Only shield when needed, take it out to restore positioning.   4. Corporate Data Security Briefcases Designed for business people, the computer backpack or accompanying briefcase is lined with signal jamming material, which can shield electromagnetic leakage of 0-18 GHz and prevent laser eavesdropping or side channel attacks in conference rooms. The material is compliance with IEEE 299/ ASTM D4935 anti-information leakage requirements which can fully ensure information security.   5. Smart Switch Functionality - Manual Control Over Connectivity Combination of signal jamming fabric and ultra-thin conductive zipper, once zipper closed it is full shielding, zipper opened 2 cm signal recover right away. Users can manually decide when to be "online".   To validate the effectiveness of Faraday bags, former FBI Supervisory Special Agent Emmanuel Ladsous conducted a series of thorough experiments. During the tests, he placed active devices—connected via Bluetooth, Wi-Fi, AM/FM radio, and cellular networks—inside the Faraday bag. Once the bag was sealed, the devices quickly lost all signal connections. This clear and direct demonstration of the bag’s shielding capabilities provides compelling proof of its reliability and has significantly boosted consumer confidence. Future Prospects and Innovation   As communication technologies continue to evolve, new and faster wireless standards like 5G and Huawei’s NearLink are rapidly emerging, making the electromagnetic environment increasingly complex. The development of electromagnetic shielding materials is therefore far from finished. Future innovations may focus on:  Enhancing frequency coverage to support new and emerging communication standards  Improving material flexibility for integration into wearable gear, such as shielded pockets in clothing  Miniaturizing shielding components for seamless integration into consumer products  Reducing production costs through optimized manufacturing processes   Conclusion People should have the fundamental right to disconnect from wireless communication. The rise of signal-blocking fabric is turning digital privacy from a luxury into a basic necessity. Whether you’re protecting trade secrets in a boardroom, securing personal data while traveling, or simply seeking a moment of digital silence in an always-connected world, this material provides a tangible solution to invisible threats. A small piece of fabric may appear ordinary, yet it can instantly sever all wireless connections to safeguard your privacy. If you're planning your next bag design, consider incorporating this “invisible shield” right into it!     Author

Both flexible and rigid packaging have a wide range of uses in the present packaging industry. They have exclusive, as well as overlapping areas of application. The differences, however, lie in construction, durability, customizability, and pliability. Weight and Size of Packaging When it comes to the weight of the packaging, rigid packaging is heavier than flexible packaging. That’s because rigid packaging is often made from denser and thicker materials. For example, paperboard boxes, tin cans, or glass bottles. Flexible packaging such as sealed pouches, on the other hand, uses lighter materials such as plastic or polypropylene. The size of the packaging depends on the requirements. Rigid packages generally take up more space as they cannot be squeezed together when bundled. Rigid packaging is meant to prevent the deformation of its inner contents. Flexible packages are flat, can bend easily or be bundled together to save space. This makes flexible kraft paper or poly mailers the go-to solutions to ship soft goods.Durability and Barrier Properties Rigid packaging better protects its contents. But, it’s prone to external deformation. For example, the surface can be easily dented or scratched, damaging the surface or print. Flexible packaging does not dent or deform easily. Although such packs could be damaged during shipping if pierced by a sharp object, flexible packaging is less likely to be affected by cosmetic abrasion. Fragile products are usually shipped using rigid packaging. Electronic items— such as computer processors, smartphones, cameras, televisions— come in rigid packaging coupled with protective packaging like styrofoam or air pillows. In all these cases, the cost of rigid packaging is often a very small fraction of the actual product cost. Flexible packaging is often used in low-cost products in the food and cosmetics industry. Chips, biscuits, bread, milk, frozen food, sauces, creams – all come in flexible packaging. Flexible Packaging in the Food Sector: Flexible packaging is dominating flexible food packaging trends. That’s because of its protective properties. For example, retort pouches are becoming increasingly popular owing to their construction. They are made up of multiple layers of polymers and often metalized sheets, such as aluminium. This offers chemical and thermal shielding to the products on the inside. The pack offers an air-tight barrier, prevents exposure to light and heat, and is temperature tolerant to help retain the freshness of its contents. A classic example is the Paper Boat pouch that’s broken the conventional trend of using rigid cartons for beverages to adopt flexible packaging. However, there are exceptions too. The Pringles packaging, for instance, is rigid packaging made from tin and cardboard, with an inner layer that offers great protection.

PE coated paper, also known as polyethylene-coated paper, is a type of paper that has a layer of polyethylene (PE) applied to its surface. This coating enhances the paper's properties, making it highly resistant to water, oil, and other liquids, making it ideal for a wide range of packaging applications. The production process of PE coated paper involves a method known as extrusion coating, where molten polyethylene is applied to the surface of the paper. This process creates a smooth, uniform layer of PE that bonds tightly with the paper fibers. The paper is then cooled and dried to set the coating in place, giving the paper its enhanced properties. PE coated paper is widely used in industries such as food packaging, where moisture and oil resistance are crucial. It is commonly found in products like fast-food wrappers, beverage cups, take-out containers, and food trays. Its durability and strength make it suitable for holding hot and cold foods, while the PE coating ensures that the paper does not weaken or degrade in wet conditions.
