Abstract

A low gas barrier, multi-layer film; and a medium gas barrier, multi-layer film, a high gas barrier, multi-layer film; and a relatively elastic, multi-layer film are suitable for use on a pouch-producing, vertical, form-fill-seal machine. At least the majority of the layers may be bonded together through their having been co-extruded. The outermost layer, which may be PP, can be manufactured by extrusion to form a fist sub-film which is later laminated to the other layers of the film, which have been co-extruded to form a second sub-film. Wen the second sub-film is to provide a significant barrier to gas, particularly oxygen, it can consist of a PA; PA/EVOH/PA; EVOH; PA/EVOH; PVDC; or PA/aromatic PA/PA; 1-to-3-layer core sandwiched between two EVA-, EMA-, PP-, HDPE-, LLDPE-, POP- or LDPE- based adhesive layers, sandwiched between an outermost layer of PO, polyester, PP, or PC, and an innermost sealing layer of PO, polyester, PP, or PC, and an innermost sealing layer based on Pos (mainly) polymerized using a single site catalyst system, the layers being pigmented in such a way that an effective barrier against visible light is created. The layers of the second sub-film may be doubled by collapsed bubble co-extrusion.
