摘要： Packaging material with good gas barrier properties comprising a first and a second layer of a fibrous material, e.g. paper or cardboard, and a layer of a water based polymer, e.g. polyvinyl alcohol, placed between and in direct contact with the layers of fibrous material and functioning both as a gas barrier and as a binding agent in the packaging material.The packaging material is produced through bringing together and binding together with each other a first and a second strip or sheet of a fibrous material by means of a layer of a water based polymer, e.g polyvinyl alcohol, applied between and in direct contact with the strips or sheets. The surplus water in the thus applied polymer layer is absorbed by the fibrous material in one and/or the other strip or sheet to form the intermediate layer functioning as gas barrier and binding agent.

摘要： A flexible container for a flowable material fabricated from a multi-layer film which may include an interior layer, an exterior layer and a core layer. The core layer is composed of a blend of approximately 40 to 60 parts of a polyethylene material having a density greater than 0.930, approximately 40 to 60 parts of a linear copolymer of ethylene and a C.sub.4 -C.sub.10 alpha-olefin having a density between 0.900 to 0.930 g/cm3 and a melt index of 0.20 to 2.0 dg/min, and approximately from 0 to 10 parts of an additive. The interior layer may be composed of a material selected from the group consisting of a linear copolymer of ethylene and a C.sub.4 -C.sub.10 alpha-olefin, ethylene vinyl acetate, a metallocene catalyzed linear low density polyethylene, and any mixture thereof. The exterior layer is composed of a material selected from the group consisting of surlyn, metallocene catalyzed linear low density polyethylene, a linear copolymer of ethylene and a C.sub.4 -C.sub.10 alpha-olefin, a low density polyethylene, a medium density polyethylene, a high density polyethylene, ethylene vinyl acetate and any mixture thereof. The flexible container is self-supporting when filled with the flowable material. The flexible container has a relatively planar bottom section. The flexible container may have a resealable opening for dispensing the flowable material whereby the flexible container is compressible as the amount of flowable material inside the flexible container is reduced.
