Tyvek was invented in 1950s and commercialized in 1960s. Tyvek is a kind of high-density polyethylene, which is a continuous filament formed by hot melting and then hot bonding of polymers.
This unique technology enables Tyvek to combine the material characteristics of paper, film and woven fabric, which is waterproof, breathable, light, tough, tear-resistant, puncture-resistant, highly reflective, diffuse reflective, UV-resistant, unique in texture and touch, environmentally friendly and recyclable.
Extended data:
perform
Good protection ability, excellent chemical resistance: chemically inert to most acids, alkalis and salts, with good liquid barrier protection function. Because the fiber is fine, liquid water and oil are not easy to penetrate;
Gas and water vapor can penetrate, so it has excellent waterproof and breathable performance. Good anti-seepage function of solid particles. The special physical structure can completely block tiny mites and dust and prevent them from infiltrating. The effect of blocking bacteria is excellent.
Therefore, it can be applied to the packaging of aseptic medical products. Low fuzzing, durable, lint-free, high strength and excellent dimensional stability. Easy to process, because it does not absorb water, the dry and wet strength remains unchanged.
