Abstract
A conformable, hand-tearable, high chemical barrier closure and attachment tape made up of a film composite which contains at least one stratum layer of polyvinylidene chloride, ethylene vinyl acetate, ethylene vinyl alcohol ethylene matallized polyester or similar chemical resistance material which may be disposed between additional layers of polyethylene, the film composite coated with an appropriate pressure sensitive adhesive which is further adhered to a woven base cloth which is further coated with additional pressure sensitive adhesive. Tapes having the structure show improved chemical resistance to the 15 liquid chemicals included on the ASTM F1001 chemical test battery as compared to a competitive tapes commonly used in the protective clothing and chemical packaging industry.
