EVA is a non-toxic material
EVA, or ethylene-vinyl acetate, is a non-toxic material. It is a soft, flexible, lightweight plastic material that is easy to fabricate and form. EVA is considered a safer material for children’s toys as it does not contain harmful chemicals such as phthalates and heavy metals. It is also soft and comfortable, making it suitable for children’s toys, cushions, or puzzles. Its softness can effectively reduce the impact force and reduce the risk of children falling or getting injured while playing.
EVA is widely used in the medical field for items such as infusion bags, catheters, medical hoses, disposable surgical equipment, blood bags, and drug delivery devices. The polymer does not biodegrade within the body and is quite inert, causing little to no reaction following implantation. EVA can be easily treated by conventional sterilisation methods such as gamma rays, ethylene oxide, or high-pressure steam without losing its performance, so it is particularly suitable for disposable medical supplies.
EVA is also used in the manufacture of sports goods, household products, and toys due to its lightweight, soft, and shock-absorbent nature. It is used in football boots, running shoes, and fishing gear such as floats and fishing rods. EVA is also used in the photovoltaics industry as an encapsulation material for crystalline silicon solar cells in the manufacture of photovoltaic modules.
EVA is a safe material for applications external to the body and is commonly used to make orthoses or prostheses more comfortable for the patient. It is also used in coatings formulation for good-quality interior water-borne paints. EVA is used in orthotics, surfboard and skimboard traction pads, car mats, and for the manufacturing of some artificial flowers.

EVA is used in plastic wraps, packaging, and coatings
EVA, or ethylene-vinyl acetate, is a soft, flexible, lightweight plastic material that is easy to fabricate and form. It is a non-toxic material, making it safe for use in consumer products such as shoes, toys, and even food packaging. EVA is used in plastic wraps, packaging, and coatings due to its excellent moldability, low-temperature toughness, stress-crack and UV radiation resistance, and good clarity and gloss.
EVA is an extremely elastic material that can be processed like other thermoplastics. It is not vulcanized but has some of the properties of rubber or plasticized polyvinyl chloride, particularly at the higher end of the range. Both filled and unfilled EVA materials have good low-temperature properties and are tough. EVA is also used as a clinginess-enhancing additive in plastic wraps.
EVA is a popular alternative to polyvinyl chloride because it does not contain chlorine. It is also easy to process and recycle, making it more environmentally friendly than other plastics. EVA can be used to produce flexible, shock-absorbent parts that are simple to recycle.
In addition to its use in plastic wraps, EVA is also used in packaging as an adhesive for bonding plastic films, metal surfaces, and coated paper. It is also used in coatings formulation for good-quality interior water-borne paints at 53% primary dispersant.
EVA has a wide range of applications, including in the orthotics and prosthetic market, where it is used to make liners for rigid socket frames, providing outstanding patient comfort. It is also used in the fabrication of mouthguards, which can be softened in boiling water for a user-specific fit.
