Abstract

An environmentally friendly polymer film pouch (10) made from a polyethylene film structure for the packaging of flowable materials, for example, a pouch made from a monolayer or multilayer film structure (13) such as a two-layer or a three-layer coextruded film containing at least one layer of a blend of a substantially linear ethylene polymer and a high pressure low density polyethylene as a seal layer (12).
Also disclosed is a process for making the pouch for packaging flowable materials using a film structure described hereinabove.
