In which industries are EVA bags most widely used?
EVA bags, which are made of ethylene-vinyl acetate copolymer (EVA), are widely used in many industries because of their lightness, durability, heat preservation and waterproof properties. The following are the industries where EVA bags are most widely used:

1. Shoe material industry
Shoe material is the main application field of EVA resin in my country. EVA bags are widely used in the soles and interior materials of mid-to-high-end tourist shoes, mountaineering shoes, slippers and sandals because of their softness, good elasticity and chemical corrosion resistance. In addition, EVA materials are also used in the fields of sound insulation boards, gymnastics mats and sealing materials

2. Photovoltaic industry
EVA plays an important role in the photovoltaic industry, especially in the solar cell industry. EVA is used to bond the cell sheets in crystalline silicon cells to the surface photovoltaic glass and the cell backplane. EVA film has good flexibility, optical transparency and heat sealing, making it the first choice for photovoltaic packaging materials. As the world pays more and more attention to renewable energy, the solar photovoltaic market is showing a rapid growth trend. As a key component of solar panel packaging materials, the demand for EVA is also rising.

3. Packaging industry
EVA bags are also widely used in the packaging industry, especially in protective packaging and cushioning packaging. EVA materials have excellent compression resistance, cushioning, shockproof properties, good resilience and flexibility, and its environmental protection characteristics, making it unique in the fields of electronic product packaging and medical device packaging.

4. Cable industry
EVA resin is also widely used in the wire and cable industry, especially in halogen-free flame-retardant cables and silane cross-linked cables. EVA resin has good filler tolerance and cross-linkability, so the EVA resin used in wires and cables generally has a vinyl acetate content of 12% to 24%.

5. Hot melt adhesive industry
Hot melt adhesive with EVA resin as the main component is very suitable for automated assembly line production because it does not contain solvents, does not pollute the environment and has high safety. Therefore, EVA hot melt adhesive is widely used in book wireless binding, furniture edge banding, automobile and household appliance assembly, shoemaking, carpet coating and metal anti-corrosion coating

6. Toy industry
EVA resin is also widely used in toys, such as children’s wheels, seat cushions, etc. In recent years, my country’s toy processing industry has developed rapidly, and production is mostly concentrated in coastal areas such as Dongguan, Shenzhen, Shantou, etc., mainly exporting and processing abroad

7. Coating industry
In the field of coating materials, pre-coated film products have the largest demand for EVA. Pre-coated film products are made by compounding coating-grade EVA and substrates in the process of heating and pressurizing. They are environmentally friendly, can be laminated at high speed, have high lamination quality and high bonding strength. The downstream of pre-coated film is mainly used in the packaging of books and food in the field of industrial printing, digital printing and commercial advertising in the field of commercial printing, and building materials in the special product market, etc.

In summary, EVA bags have been widely used in many industries such as shoe materials, photovoltaics, packaging, cables, hot melt adhesives, toys and coatings due to their unique physical and chemical properties. With the continuous advancement of technology and the expansion of market demand, the application of EVA bags in these industries will be further deepened and expanded.
