Abstract: Described is an aqueous cold seal adhesive in the form of an aqueous polymer dispersion comprising a mixture of a first polymer and a second polymer, wherein the first polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of C1 to C20 alkyl (meth)acrylates and has a glass transition temperature of less than 0° C.; and wherein the second polymer is an emulsion polymer prepared in the presence of a protective colloid and is composed to an extent of at least 60% by weight of principal monomers selected from the group consisting of vinylaromatics having up to 20 C atom, and has a glass transition temperature of at least 50° C. Also described are cold sealable coated polymer films coated with the aqueous cold seal adhesive and a method for producing a cold-sealed pack by applying the aqueous cold seal adhesive to a packaging substrate.

Abstract: The present invention relates to a copolyamide (CoPA) produced by polymerizing a lactam (A) and a monomer mixture (M), where the monomer mixture (M) comprises 1,5-diamino-3-oxapentane. The present invention further relates to a polymer film comprising the at least one copolyamide (CoPA), to a process for producing the polymer film, and to the use of the polymer film (P) as a packaging film.
