摘要

A multilayer, sealable laminating film based on an inner layer of ethylene/vinyl alcohol copolymer contains 0.1-3 wt% of a sorbitan mono-ester (based on total film weight). Multilayer, sealable laminating film comprising (from the inside outwards): (a) an inner layer (i) of ethylene/vinyl alcohol copolymer; (b) layers of coupling agent (ii)/(ii') on the sealing side and laminating side respectively; (c) at least one other layer (iii) on the laminating side and at least one layer (iv) on the sealing side; (d) the sealing layer (v) (applied to (iv)). This film contains 0.1-3 wt% of a sorbitan mono-ester (I) (based on the total wt. of film). An independent claim is also included for packaging material containing this film.
