摘要

Flexible packaging material in sheet or strip form for making into liquid containers with good oxygen tight properties, comprises a skeletal layer (11) composed of a mixture of plastics and filler, and a barrier layer (12) secured thereto by surface fusion when the layers are co-extruded. The layer (12) is composed of two plastics components, one of which is the same as that of the skeletal layer.
