EVA (Ethylene Vinyl Acetate) foam is a versatile polymer elastomer widely used in the manufacturing of bags and shoes. This material offers numerous advantages, including being lightweight, flexible, and providing excellent shock absorption for comfort. Due to these properties, it is an ideal choice for shoe insoles, midsoles, and padding in backpacks.

Ethylene Vinyl Acetate, or EVA, is a polymer elastomer that can create soft and flexible foam. Insoles for various types of shoes, including sports shoes, medical shoes, bags, and backpacks often use this foam. Men’s and women’s canvas shoes are designed with foam soles for comfort, optimal fit, and lightweight. EVA foam can be manufactured in compressed (hard) and soft, flexible forms. We should delve deeper into EVA foam.
EVA foam is an ideal material for canvas and medical shoes due to its many advantages. EVA sole is a plastic shoe sole that is light and flexible compared to rubber, making it more comfortable for the feet. It has strong durability and can endure environmental temperatures.
Shoe foam is one of the most efficient and affordable materials that Nike uses in its shoes. Shoes with shock-absorbing foam have many benefits, including reducing stress on the joints when walking. In making bags, it reduces the pressure on the shoulders and back, and spreads the load on the surface.
EVA foam is commonly used for midsole shoe insoles, particularly in canvas shoes, although polyurethane foam (PU) is more widely recognized in this field, as previously stated. Hydraulic impact testing was used to conduct both short-term and long-term mechanical tests on canvas shoe insoles with midsoles made of both PU and EVA foam. According to short-term tests, PU midsole insoles can be modified for various cushioning properties, whereas EVA foam midsoles have moderate values in this range. Although, EVA foams displayed relatively more significant changes in cushioning parameters over time in comparison to PU materials during extended tests, suggesting that their strength and ability to withstand cracking and tearing are greater than PU, leading to an extended lifespan of the shoes.
In the bag-making industry, EVA foam is commonly utilized. Its higher density makes it an ideal material for backpack padding.
Different Types of Foam and their Properties: Foams are available in various types, with open-cell foams being quite lightweight and soft. Closed-cell EVA foams are the preferred choice for bags and backpacks. These rigid, dense polymers meet the standards required for backpack padding. Fabric and plastic can be used for lamination as well.
Foam is a great material to use for making bags and shoes because it creates lightweight and comfortable products. Properties of foam used for bag and shoe-making include being hypoallergenic, antibacterial, and skin-friendly.
The foam bag and shoe-making industry uses a variety of sheets including compressed foam, lightweight polyethylene, textured T-trek, and honeycomb sheets with different textures such as honeycomb, chain, needle, seven and eight-shaped, almond, herringbone, wrinkled, and mat-like.
Foamiran primarily uses EVA foam (Ethylene-Vinyl Acetate) for the production of bags, shoes, and backpacks. This foam is chosen for its lightweight nature, flexibility, and durability, which are crucial for this industry.
EVA foam is used to create the soles and insoles of various types of footwear, including athletic shoes, casual shoes, and medical shoes. The foam acts as a cushion and shock absorber, reducing pressure on the joints and providing a lightweight and comfortable feel.
In bags and backpacks, foam is used for cushioning and padding. Its high density and durability make it ideal for the shoulder straps and back panels of backpacks, helping to distribute the weight evenly and reduce pressure on the shoulders and back.
EVA foam offers several key advantages for footwear:
While PU (Polyurethane) foam may show better shock dampening in short-term tests, EVA foam has proven to have greater long-term durability and resistance to cracking and tearing. This makes EVA foam a more reliable choice for shoe manufacturers.
