The characteristics of the tyvek medical paper

特卫强( Tyvek) Commonly known as 'the tear is not bad,' are trademarks of dupont series of sheet products, it is composed of numerous small and highly of polyethylene fiber spinning sticky spun-bonded olefins ( 纺粘的烯烃) , this kind of unique jet spinning technology to produce light weight, and is very tough material. Its advantages include: 1, the thickness of thin, light weight, it is not easy deformation, soft, smooth, light and tenacity, good opacity, combined with paper, cloth, and has the characteristics of thin film; The characteristic of moisture proof, resistance to water damage, excluding glued to agent. 2, the waterproof breathable resistance bacteria, - 73 degrees can still maintain flexibility and high strength; 118 degrees contraction; 135 degrees began to melt. Folding ( Allow more than 20000 times repeated) Collection, flexible cloth ( For a fraction of) , film is smooth, the appearance of the paper ( Half the weight of paper) In one of the features. 3, good biological compatibility, shed no dust, high value-added, high tear strength of packaging, high burst packaging, high power, high resistance bacteria period ( More than 5 years) , high permeability, To reduce the generation of extreme temperature condensate) , more safety. Therefore applied in medical packaging, it is now recognized as one of the best medical packaging materials ( Now for the best medical packaging) in the dialysis material 。 Suitable for class II and class III medical device packaging.
