Tear Resistance Polyethylene Vinyl Acetate Versus Polyethelene

Plastic films are used in a wide variety of applications.

Tear resistance polyethylene vinyl acetate versus polyethelene.

Because pva is a emulsion not a true water solution once the film is dry it. Thus it is often used in the food contact layer. These thin plastic membranes are used to separate areas or volumes to hold items to act as barriers or as printable surfaces. Packaging plastic bags labels building construction landscaping electrical.

Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Thicker plastic material is often called a sheet. Blends of ethylene vinyl acetate eva with low density polyethylene may have densities up to 0 929 g cm 3. In addition pva may be added to cement concrete where it can improve the water resistance properties.

Plastic film is a thin continuous polymeric material. D2103 specification for polyethylene film and sheeting. Poly vinyl acetate poly vinyl acetate pva is a thermoforming resin that is usually water carried and generally used for the wood working and diy industries. The following charts illustrate relationship between permeability tear strength and tensile.

Eva plastic film performs excellent in bonding strength offers heat resistance cold resistance humidity resistance and tensile strength. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.
