A semi-rigid, heat-sealable laminate with permanent antistatic characteristics comprising a semi-rigid packaging material having a coating of heat-sealable antistatic plastic. 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.

A semi-rigid heat-sealable, laminate with permanent antistatic characteristics comprising a semi-rigid deformable substrate having a surface with a surface portion for supporting an item to be packaged, and a heat-sealable, permanently antistatic layer extending over and bonded to said surface, said layer including a modified acid copolymer selected from: (I) a mixture of (A) a polymer containing carboxyic acid moieties and (B) an antistatically effective amount of a quaternary amine; or from (II) an acid/base reaction product of (A) a polymer containing carboxylic acid moieties and (C) an antistatically effective amount of an organic base wherein (A), (B), and (C) are defined as follows: (A) the polymer containing carboxylic acid moieties is a copolymer of (i) an alpha-olefin of the formula RCH〓CH2 wherein R is H or C1 to C20 alkyl, C1 to C20 alkoxy, or C6 aryl, and (ii) an alpha,beta-ethylenically unsaturated carboxylic acid, and (B) the quaternary amine is of the formula [(R1)(R2)(R3)(R4)N│+[X│- wherein R1 is selected from H, aryl, or C1 to C50 alkyl optionally having one or more non-contiguous C〓O or NHC〓O or -S-or -O-in the carbon chain, or the same as R2; each of R2, R3, and R4 is the same or different and selected from H, C1 to C18 alkyl optionally substituted with one or more OH or from -(R5-O)a-H where a is an integer from 1 to 10 and R5 is ethylene or propylene; and X is an anion selected from chloride, bromide, iodide, fluoride, nitrate, fluoborate, phosphate, C1 to C20 alkyl phosphate, sulfate, C1 to C20 alkyl sulfate, formate, C1 to C20 alkyl or C6 to C24 alkaryl or aryl sulfonate, acetate, trifluoroacetate, citrate, propionate, or tartrate, and (C) the organic base is of the formula M + Y -, wherein M +is [R6R7R8R9N]+, where R6, R7, R8, and R9 are independently selected from a C1 to C4 alkyl, benzyl, 2-hydroxyethyl, or hydroxypropyl, and Y│-is selected from hydroxide, C1 to C4 alkoxide, bicarbonate, or carbonate.
