Aerosol cans, as a convenient form of packaging, are widely used in a variety of fields such as personal care, household cleaning, food and so on. With consumers increasingly concerned about environmental protection and convenience, the aerosol can industry is facing unprecedented opportunities for growth. This article explores future trends in the aerosol can industry, particularly in terms of sustainability, intelligence, and technological innovation.

-Sustainability: environmentally friendly materials and design

As the world becomes more aware of environmental protection, the aerosol can industry is progressively adopting more environmentally friendly materials and designs. Aluminum aerosol cans are preferred for environmentally friendly packaging due to their 100% recyclability. Manufacturers are working to increase the use of recycled aluminum and reduce the need for raw material extraction, thereby reducing energy use and greenhouse gas emissions. In addition, the application of lightweighting technology is also playing an important role in reducing material use and carbon emissions.

-Intelligent: integrating sensor and IoT technologies

Another notable trend in the aerosol can industry is intelligence. By integrating sensors and wireless communication technologies, smart aerosol tin cans are able to monitor the remaining amount, remind replacement, and integrate with smart home systems to provide a more convenient user experience. This intelligence not only enhances the user experience, but also helps in the effective management of resources.

-Market expansion: growth in emerging markets

Adoption of aerosol cans is on the rise as consumers in emerging markets continue to demand convenience and sustainability. Countries in Asia, Latin America and Africa are experiencing increased urbanization and the rise of the middle class, leading to increased consumption of personal care, household and pharmaceutical products. Aluminum aerosol cans are seen as a premium packaging option with durability, portability and environmental benefits that appeal to consumers in these regions.

-Environmental regulations: promoting green development of the industry

Increasingly stringent environmental regulations are placing higher demands on the aerosol can industry. Enterprises need to continue to develop environmentally friendly materials and processes to reduce the impact of products on the environment. At the same time, the government also through the development of relevant policies and standards to promote the green and sustainable development of the aerosol can industry.

-Conclusion

Future trends in the aerosol can industry suggest that sustainability, intelligence and technological innovation will be key drivers of industry growth. As consumer demand for environmentally friendly and convenient products continues to grow, the aerosol can industry must adapt to these changes to remain competitive in the market. By adopting environmentally friendly materials, smart technologies and continuous technological innovation, the aerosol can industry is expected to achieve sustainable growth while meeting consumer needs and expectations.

 

 

 

There are currently over 200 types of aerosol products used in personal, household, industrial, agricultural, construction, fire protection, safety, medical and other fields.

The aerosol valve may not seem eye-catching, but it is of utmost importance compared to the entire aerosol product. It not only affects the sealing performance of the product, but also the spraying effect, and of course, the stability of the entire aerosol product. Therefore, how to choose the appropriate valve is worth everyone's attention in the development process of aerosol products.

If we look at the types of valves, aerosols are mainly divided into two categories: one-component packaging and two-component packaging (BOV system). The main structure of one yuan aerosol includes: aerosol can body, aerosol valve, outer cover, actuator, propellant, and raw materials. The main results of binary aerosols include: aerosol can body, aerosol spray valve, extra layer of aluminum bag, outer cover, actuator, raw materials, and compressed gas.

Valves usually consist of seven parts: sealing cup, outer gasket, inner gasket, valve stem, spring, valve chamber, suction tube, etc. Considering different materials, sizes, and structures, theoretically, valves can exhibit billions of different variations.

Therefore, how to choose the appropriate spray valve requires comprehensive consideration of the following factors:

Firstly, is it a one-component valve or a BOV valve?

The compatibility issue needs to be considered when mixing the material and propellant in a one-component aerosol formulation. When both the propellant and the contents are sprayed out simultaneously, it is easy to produce a situation where the propellant has already been sprayed out while the material remains, which affects the consumer experience. Cannot be used 360 degrees, can only be used upright or upside down. Volatile propellants (such as butane or dimethyl ether) have a geometric fold increase in pressure with temperature, and are classified as hazardous materials with strict requirements for transportation and storage conditions.

Without considering cost factors, BOV valves have many advantages, such as:

The contents do not directly come into contact with the aerosol can, providing protection for the raw materials;

Spray out in all directions to adapt to diverse consumption scenarios;

Before filling, the valve bag can be vacuumed or disinfected by cobalt 60 irradiation. The formula can reduce preservatives and allergens;

The pressure inside the tank is constant, the spraying is stable, and the residual material is low;

Using compressed air or nitrogen, the pressure remains almost constant with increasing temperature, and the requirements for transportation and storage are relatively low.

Secondly, the choice of material for the sealing cup?

The thickness of tinplate cups is usually 0.27mm, and the thickness of aluminum cups is usually 0.42mm. The application in the field of personal care products usually uses aluminum cups, which are more stable and less prone to rusting. The size stability of the tinplate cup is better, and it is not easily affected by the aerosol can body or sealing process;

Thirdly, the material of the gasket

Gaskets are usually divided into inner gaskets and outer gaskets, with various materials including butyl, chloroprene, butyl, chlorobutyl, nitrile, chloroprene, polyurethane, and so on. Shrinkage of the gasket will affect the fit between the valve stem and gasket, sometimes leading to leakage. If the gasket expands excessively, the valve stem hole of the gasket cannot be exposed when pressing the nozzle, which will affect the spraying efficiency. After repeated experiments, a mixture of 75% ethanol and 25% isopentane was used for gold testing, and the best choices were chloroprene rubber (NEOPRENE) and butadiene sodium rubber (BUNA), which were relatively stable.

Fourth: Valve stem orifice

Common sizes include 0.35, 0.4, 0.46, 0.51, and 0.61mm, and the number of valve stem holes is one of the determining factors for the ejection rate. There are also different series of valve stem air holes, including 1, 2, 4, 6, and even 8 holes.

Fifth: Valve side hole

The gas phase side hole is located on the valve housing and is located inside after the valve is sealed. It is mainly used to increase atomization effect, increase the stability of content spraying for some powder products, and increase the spraying of high viscosity products. There are both single hole and double hole designs.

Sixth: Dip tube length

At the initial setting, the valve length can be calculated as the total height of the aerosol can minus the set value. Then, through compatibility testing, confirm the degree of shrinkage of the dip tube in the product, and the final valve length should be such that the bottom of the dip tube is at the lower one-third of the half circle at the bottom of the can after soaking and stabilizing.

Considering that dip tube have a 3-6% expansion rate, it is crucial to confirm the length after compatibility testing. Of course, a straw design with oblique cuts can also be slightly helpful.

Paired with appropriate buttons, the selected aerosol valve can convey the characteristics of the aerosol to consumers. As a packaging solution for complex products, compatibility and stability testing are required to design stunning products!

 

Definition

2K aerosol cans are specialized containers that typically have two separate openings, each of which can be used to release or fill contents. This design distinguishes them from traditional single-opening aerosol cans.

	This can have a partition structure inside to prevent premature mixing of two different contents. They are only allowed to come into contact through specific operations when needed.

How to install and use?

The short valve is installed on the side filled with curing agent. Before use, press the black button to mix curing agent with spray paint, and then press the white nozzle to use spray paint.

 

The working principle of a 2k (two-component) paint can is to pack two different components (usually paint and curing agent) in two different tanks or chambers, mix them together through a specific device or operation when used, and then spray. Before mixing, the two components are independent of each other and do not undergo chemical reactions. When spray painting is required, the channel connecting the two components is opened by pressing the nozzle, rotating the pull ring, or other operation, so that they are mixed at the nozzle. The mixed paint will cure quickly in the air to form a hard, durable paint film.
