LAMINATED ANTI-STATIC PACKAGING, ANTI-STATIC LAYER HAS A CARBOXYLIC ACID COPOLYMER AND A QUATERNARY AMINE OR A BASE

摘要

A semi-rigid, heat-sealable laminate (10) with permanent antistatic characteristics comprising a semi-rigid packaging material (12, 14) having a coating of heat-sealable antistatic plastic (13). The antistatic plastic is a film of a modified acid copolymer. The modified acid copolymer is selected from (I) a mixture of (A) a polymer containing carboxylic acid moieties and (B) an antistatically effective amount of a quaternary amine, or (II) the acid/base reaction product of (A) a polymer containing carboxylic acid moieties and (C) an antistatically effective amount of an organic or inorganic base.
