MULTI-LAYER FLEXIBLE CONTAINER FOR FLOWABLE MATERIALS

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 20 to 100 parts of a linear C4-C10 alpha-olefin polyethylene material having a density greater than 0.930 and 0.970 g/cm<3> and a melt index of 0.2 to 2.0 dg/min, approximately 0 to 80 parts of a linear ethylene and a C4-C10 alpha-olefin copolymer having a density between 0.900 to 0.930 g/cm<3> 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 C4-C10 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 C4-C10 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.
