Silk-screen printing refers to the method of obtaining graphics through scraping and printing using screen hollowed out boards and printing materials. During the printing process, the ink on the printing plate leaks from the through-hole of the layout to the substrate under the pressure of the scraper, forming the same image and text as the original manuscript. It originated in China and has a history of over 2000 years. At present, there are semi-automatic screen printing machines and fully automatic screen printing machines for cosmetic glass bottles. The fully automatic screen printing machine has higher requirements for bottle shape, but the output is higher. As a brand, when selecting cosmetic glass packaging materials, attention should also be paid to the selection of bottle types. Irregular bottle types will have more restrictions on the printing position. Before designing, you can communicate with the packaging factory to obtain the cutting line of the glass bottle to avoid design changes and wasting time.

It is not only an important item in the daily life of ancient Egyptians, but also an important carrier of their spiritual beliefs, social status, and cultural inheritance.

According to chemical knowledge, easily decomposable chemical reagents are stored in brown bottles. Some essential oils have strong photosensitivity, such as bergamot essential oil, as well as various citrus plant essential oils such as lemon, lime, and bitter orange, which are highly photosensitive. These types of essential oils must be stored in brown cosmetic glass bottles. Currently, almost all essential oils are stored in dark cosmetic bottles, such as common rose essential oils, lavender essential oils, tea tree essential oils, etc. Although these essential oils are not photosensitive, they are also stored in dark bottles. The reason is to avoid the evaporation of essential oils caused by the temperature increase caused by sunlight exposure. The essential oil components contain a large amount of aromatic substances, and the volatility of aromatic substances is high.

Introduction As a leading manufacturer in the aerosol industry,  Mgaerosolcan is dedicated to providing high-quality products and sharing valuable knowledge with our partners and customers. In this blog, we will focus on aerosol metered valves, a crucial component in many aerosol products. What is Aerosol Metered Valve? An aerosol metered valve is a precision device designed to dispense a specific and consistent amount of product from an aerosol canister. It controls the flow and quantity of the aerosolized substance, ensuring accurate dosing. These valves are engineered with meticulous attention to detail, typically consisting of a valve body, a stem, a gasket, and a spring mechanism. The valve body houses the other components and provides the structure for the valve's operation. The stem is responsible for opening and closing the valve, allowing the product to be released in metered amounts. The gasket ensures a proper seal to prevent leakage and maintain the integrity of the aerosol system. The spring mechanism provides the necessary force to return the valve to its closed position after each actuation. Ask for Sample If clients require aerosol metered valve samples for testing, please provide the following data to enable us to recommend the most suitable valves for you. 1- Which kind of propellant gas do you use for this valve, LPG or DME? 2- Is the formula highly concentrated? 3- What's the dosage of valve, conventional are 25/50/75/100 mcl 4- What's the material of aerosol valve's stem? Plastic or metal stem? 5- Which kind of gaskets?  NITRILE/ Neoprene/ Chlorobutyl gaskets? Applications and Uses of Aerosol Metered Valves Aerosol metered valves find extensive use in a wide range of industries. In the personal care sector, they are commonly used in products such as deodorants, hairsprays, and perfumes. For instance, a popular brand of deodorant uses a metered valve that dispenses exactly 0.14 grams of the deodorant formulation per spray. This precise amount is sufficient to provide effective odor protection for an average user throughout the day without over-application. In the pharmaceutical and medical fields, metered valves are essential for the accurate dispensing of medications in aerosol form, such as inhalers. Take a common asthma inhaler as an example. The metered valve in it ensures that each puff delivers a precisely measured 90 micrograms of the active pharmaceutical ingredient, allowing patients to receive the correct dosage of the medicine, which is crucial for effective treatment. In the household and cleaning products industry, aerosol cleaners, air fresheners, and insecticides often utilize metered valves. A well-known brand of aerosol air freshener can has a metered valve that emits a 0.2-ounce burst of fragrance each time it is pressed, making it easy to control the intensity and longevity of the fresh scent in a room. In the automotive industry, aerosol paints and lubricants with metered valves enable precise application. For example, a professional-grade aerosol paint for automotive touch-ups has a metered valve that deposits a thin, even layer of paint with each spray, allowing for seamless color matching and a smooth finish. Benefits of Using Aerosol Metered Valves One of the significant advantages of aerosol metered valves is their accuracy. This precision in dispensing helps to optimize product usage, reducing waste and saving costs for both manufacturers and consumers. For manufacturers, it also ensures consistency in product quality. Since the same amount of product is dispensed each time, customers can expect a uniform experience. Metered valves also contribute to product safety. By controlling the amount of product released, the risk of overexposure or accidental ingestion of harmful substances is minimized. Moreover, they enhance the convenience of using aerosol tin can products. Users can easily control the amount they need, whether it's a small spray for a quick touch-up or a larger dose for a more extensive application.

As a custom plastic tubes manufacturer, we often get asked: "What's the best packaging solution for body care products?" The debate between airless tubes and traditional tubes is heating up, and for good reason. Both options have unique advantages, but choosing the right one depends on your brand's goals, product needs, and customer expectations. Let's dive into the key differences to help you make an informed decision.​     1. How They Work: A Simple Breakdown​ Traditional Body Care Tubes​ Traditional tubes are the classic choice you've seen on store shelves for decades. They work like this: squeeze the tube, and product flows out through the opening. They typically have a simple design with a screw-on cap or flip-top lid. These tubes rely on external pressure to dispense product, which means air can easily enter the tube every time you open it.​ Airless Tubes​ Airless tubes use a clever mechanical system to keep air out. Inside, there's a piston or diaphragm that moves up as you squeeze the tube, pushing product out without letting air in. This "airless" design prevents oxidation, bacterial growth, and product waste. Think of it as a pump system built directly into the tube—no need for separate pumps or jars.​ 2. Performance: Which Keeps Products Fresher?​ Traditional Tubes: Vulnerable to Air and Bacteria​ Every time you open a traditional tube, air mixes with the product. This exposure can cause:​ Oxidation: Ingredients like natural oils or vitamins break down faster.​ Bacterial growth: Moist environments inside the tube can foster microbes, especially for water-based products.​ Product drying out: Openings allow moisture to evaporate, changing texture over time.​ Airless Tubes: Lock in Freshness and Efficacy​ Airless technology solves these problems by:​ Sealing out air: No oxygen means slower ingredient degradation.​ Preventing contamination: The piston system minimizes contact with external elements.​ Maximizing product use: The design ensures you can squeeze out every last drop, reducing waste by up to 30% compared to traditional tubes.​ Why it matters for brands: If your products contain sensitive ingredients (like retinol, hyaluronic acid, or essential oils), airless tubes protect their efficacy, extending shelf life and enhancing customer satisfaction.​ 3. User Experience: Convenience vs. Innovation​ Traditional Tubes: Familiar but Flawed​ Pros:​ Easy to use—just squeeze and go.​ Affordable upfront costs.​ Cons:​ Hard to control product flow (ever had a glob of lotion squirt out too fast?).​ Difficult to use when the tube is nearly empty (hello, rolling up the ends!).​ Not ideal for thick formulas like creams or serums, which can get stuck in the tube.​ Airless Tubes: Modern and User-Friendly​ As a custom plastic tubes manufacturer, we don’t just sell tubes—we solve problems. Whether you need a traditional tube for a mass-market lotion or an airless design for a luxury serum, we’ll help you:​ Select the right materials (recyclable, UV-resistant, etc.).​ Optimize costs without compromising quality.​ Add unique features (matte finishes, custom colors).​ Contact us today to discuss how packaging can elevate your brand—and keep your products performing at their best.
