aerosol tin cans

Tinplate aerosol cans (3-piece tinplate cans) are classified as pressure packaging containers, so purchasing them requires strict attention to material quality, pressure resistance, welding stability, internal lacquer, valve compatibility, and transport safety. Below are the essential points every buyer should check before placing an order. Structure & Specifications 1. Confirm standard dimensions Common diameters: 45/52/57/60/65/70 mm Height: 100–300 mm Make sure size and structure meet local market requirements (EU/US/SEA). 2. Tinplate thickness Typical thickness: 0.18 / 0.20 / 0.22 / 0.23 mm Recommended: Daily chemical products: 0.20–0.22 mm Industrial/automotive chemicals: 0.22–0.23 mm Pressure & Safety Standards 1. Request a full pressure test report Reports must include: Test Standard Requirement Leak/Pressure Resistance Test ≥ 12 bar (industrial products 15–18 bar) Burst Test ≥ 18–22 bar If a supplier cannot provide these tests, do NOT purchase. 2. Bottom dome quality Check for: Uniform deep drawing No deformation or dents No sharp edges or burrs The can bottom supports most of the internal pressure. Tinplate Material & Internal Lacquer Correct internal lacquer Internal coating must match chemical properties: Product Type Recommended Internal Lacquer LPG (propane/butane) Epoxy lacquer Brake cleaner / Engine cleaner Gold anti-corrosion lacquer Insecticide Food-grade epoxy Strong solvents Epoxy-phenolic lacquer Cans without proper internal lacquer will corrode over time.

Key points for choosing aerosol cans 1. Stability/compatibility For any aerosol can product, the first thing is to ensure the stability and reliability of the product. The cans of the selected products are tested for compatibility and stability based on the type of product and the characteristics of the formula. Only with data support can we have a theoretical basis for products to flow into the market. Of course, the stability test does not mean that there is no problem 100%. It is only a representative test. There may be unknown problems in the follow-up, but it can represent the vast majority. 2. Security Safety is the first priority for any project. The safety here includes usage safety, pressure safety, environmental safety, toxicological safety, the proportion of the contents in the aerosol can’s full water weight, etc. What R&D engineers develop is not only products that can bring profits to the boss, but more importantly, safe products that can bring benefits to society. 3. Economical Excessive use of packaging materials is actually a waste of resources, so choosing suitable packaging materials is a suitable way to protect resources.

There are four major components of an aerosol products, the aerosol can, the valve, the feed, and the ejector gas. Factors affecting the quality of aerosol cans, from raw materials, can-making equipment and processes to quality testing, there are many, the following is a brief introduction: 1、The quality of tinplate materials: Tinplate substrate for the manufacture of cans requires high purity, such as impurity content is too high, affecting the ductility, brittleness, hardness and other processing properties and corrosion resistance.The tinplate materials we use are of the highest quality, one of the best tinplate, the quality is guaranteed! 2、The quality of cans body welding and repainting: For tinplate cans, one of the weaker links is the weld, which requires strict mechanical properties. The welding machine used in our Sihai factory is the world famous Switzerland SOUDRONIC machine, the quality is guaranteed. 3、Leak detection: Aerosol products are mostly flammable and explosive products, each factory empty aerosol cans must be tested by online pressure leakage detection machine, and at the same time must be in accordance with the provisions of the deformation pressure and bursting pressure sampling, in order to ensure the safety of the product production, storage, transportation and use. Our Sihai factory not only has automated gas detection, but also manual hand inspection link, product safety can be assured.

1920-1950 In 1927, Norwegian engineer Erik Rotheim filed a patent for what would become an amazing success story: the aerosol dispenser. The successful development of a mass-produced aerosol occurred in the United States in the late 1940s. It was developed by Goodhue & Sullivan as an insecticide called "bug bomb". American soldiers used it to fight insect-borne diseases in the Pacific; 50 million were produced during World War II. Soon after the war, aerosol packaging expanded. in 1947, 4.3 million units were produced for civilian use. Production grew steadily and soon crossed the Atlantic to Europe. 1950-1960 Insecticides and hairsprays were the first products to enter the European market in the early 1950s. Air fresheners, deodorants and shaving foams soon followed, and about 70 million aerosols were produced in Europe during this period. 1960-1970 In the early 1960s, there was a golden age for the aerosol industry. A wider variety of aerosol products entered the market; they were initially made of extruded aluminum, but soon were also made of tinplate. 1970-1980 Production shocked again, reaching 2.2 billion units; an increase of 80% in ten years! During this period, interest in aerosols began to grow. In the late 1970s, after the publication of the "Molina/Roland" report on the ozone layer, a wave of environmental problems captured the world's attention. Aerosols were thought to represent the role played by chlorofluorocarbons (CFCs) in the thinning of the upper ozone layer, although its contribution to this phenomenon was relatively small. 1980-1990 In the 1980s, the aerosol industry voluntarily switched from CFCs to alternative propellants, and FEA was the first organization to formalize a voluntary environmental agreement with the European Commission (Commission Recommendation 89/349/EEC). Since 1989, aerosols for European consumers (except for a few medical products such as asthma inhalers) have been CFCs-free. Production increased by 35% during this decade to 3 billion units. 1990-2000 Since the early 1990s, the protection of the environment has become a key issue in Europe. Research and development has focused on propellants, packaging and ingredients to make aerosols high-performance products. Two-component aerosols offer a new generation of aerosol technology and are beginning to expand rapidly. Following the use of alternative propellants to CFCs, the aerosol industry has demonstrated through various studies that empty aerosols can be effectively included in the normal household waste packaging stream without causing harm. As a result, post-consumer aerosols began to be successfully recycled around the world. Aerosol production in Europe proceeded steadily to 4.4 billion units, an increase of 48% in this decade, making Europe the global leader in production. 2000-2010 In 2002, the FEA adopted a code of practice on the use of HFCs. Hydrofluorocarbons (HFCs), which have no impact on the ozone layer but are still involved in climate change, should only be used in the aerosol industry in applications where there are no other safe, practical, economical or environmentally acceptable alternatives, i.e. only in technical applications with an ignition source or in pharmaceutical applications. Aerosol packaging comes in new shapes, more attractive and ergonomic. Europe remains the world leader in aerosol production with 5 billion units produced. in 2008, almost 12 billion units were produced worldwide. 2010-2020 Compressed gas propellants are more widely used and the aerosol industry is focused on producing more cost effective aerosol containers. While plastic aerosols are further developed in the market, maximum efforts are made to improve new systems, such as self-compression bags. The Future Embrace the circular economy through multi-stakeholder dialogue to ensure more efficient recycling of aerosol dispensers.

We can make customized aerosol cans for you according to your requitments. If you are interested in our products, please feel free to contact us.

There are 2 basic Aerosol Tin Can Classifications. Necked-in, Straight Wall. The propellant in these cans are either classified as Liquefied Gas, or Compressed Gas. The cans are made up of either 2 pieces or 3 pieces. Both Aerosol Straight-wall and Necked-in Cans are used in the personal care, household, paints, automotive, insecticide, and industrial product industries. You will see the difference in Straight-wall and Necked-in Cans by looking at the very top of the can which is where it is sealed. The Necked-in can will indent before going into the rim, and the Straight-wall will continue directly into the rim without any deviation. Both are durable, however necked-in cans are considered extremely durable. Aerosol cans are made in various ways, normally from metals that can safely contain pressurized liquids and gases. Most everyday, household aerosols are made from a thin sheet of steel coated with another material to stop it rusting or reacting with the product or the propellant. Traditionally the coating is tin, often applied by electroplating, which turns the steel into a material called tinplate. The tinplate is wrapped into a cylinder that has a top and a bottom welded on to ensure the can is completely leak proof. Environmentally friendly cans are increasingly being made with plastic (polymer) linings instead of tin, which is often cheaper and makes them easier to recycle. Other cans are made by pressing a small lump of aluminum through a ring-shaped tool, called a die, so a cylinder forms from a single piece of metal.

Aerosol sprays contain a substance that is compressed into a liquid. When we press on the nozzle, the liquid in the tank is dispersed in the air in a fine mist. The pressure inside the tank is much higher than outside the tank, so when the actuator is pressed, the chemical can be forcibly ejected, and over a long distance. This is dangerous because the force can injure people and the distance it travels can make it difficult to control. Please pay close attention to the aerosol valve. The jar valve regulates the amount of chemical released. Press the nozzle at different pressures to release the right amount of liquid. If this valve is damaged, there may be a slow leak problem, which is dangerous. The storage of aerosols is subject to certain conditions: 1- Aerosols need to be stored in a dry place, and it is forbidden to store in a high temperature place. Because high temperatures can increase the pressure inside the aerosol can, the pressure reaches a certain level that may cause an explosion. Please do not place it near a window, in the sun or in a vehicle to avoid danger from overheating the tank. Since the gas or liquid inside may be flammable, it should be stored away from any fire point, including heaters, ovens, test lights, or staff smoking areas. Please store in a well-ventilated place. A ventilated area can quickly spread dangerous fumes if any gas leaks from the can. 2- Avoid freezing 3- Aerosols should not have anything on them during storage. Aerosol cans should be stored in safe, well-ventilated areas. Having a cabinet dedicated to aerosol storage can make storage simple.
