FIELD: process engineering.
SUBSTANCE: invention relates to polymer composite film with barrier functions intended for use in agriculture as insulating film for mulching, fumigation and to method of making such films. Proposed film comprises, at least, one polymer as a base whereto applied is, at least, one barrier layer composed of composition formed by binders, additive and carrier fluid. Note here that binders can be cross-linked and, after cross-linking, can absorb water and form the gel.
EFFECT: better barrier functions, longer life, good processing ability.
