Abstract
A film for use in the formation of a flexible package that has a first layer and a second layer that are laminated together to form a two layer laminate. The first layer is a base comprising polyethylene terephthalate, with at least one of the outer surface and the inner surface having a barrier layer disposed thereon. The second layer is a coextrusion having a core layer comprising an ethylene vinyl alcohol with an outer upper layer of a linear low density polyethylene and an outer lower layer of linear low density polyethylene.
Claims19
A film for use in the formation of a flexible package comprising:
- a first layer and a second layer, the first layer having an outer surface and an inner surface, and the second layer having an outer surface and an inner surface, the inner surface of the first layer laminated to the outer surface of the second layer to form a two layer laminate,
- the first layer further comprising a base comprising polyethylene terephthalate, with at least one of the outer surface and the inner surface having a barrier layer disposed thereon;
- and
- the second layer comprising a coextrusion having a core layer comprising an ethylene vinyl alcohol with an outer upper layer comprising linear low density polyethylene and an outer lower layer comprising linear low density polyethylene.
A film for use in the formation of a flexible package comprising:
- a first layer and a second layer, the first layer having an outer surface and an inner surface, and the second layer having an outer surface and an inner surface, the inner surface of the first layer laminated to the outer surface of the second layer to form a two layer laminate,
- the first layer further comprising a base comprising polyethylene terephthalate, with at least one of the outer surface and the inner surface having a barrier layer disposed thereon, the first layer having a thickness of approximately 12 μm;
- the second layer comprising a coextrusion having a thickness of approximately 89 μm, and having a core layer comprising a 29 mol % ethylene ethylene vinyl alcohol with an outer upper layer comprising linear low density polyethylene and an outer lower layer comprising linear low density polyethylene, with an upper tie layer between the upper outer layer and the core layer, and a lower tie layer between the lower outer layer and the core layer, the core layer having a thickness of approximately 8 μm, with each of the upper outer layer and the lower outer layer having a thickness of approximately 33 μm.
A pouch comprising:
- a front panel and a back panel sealed together with a seal to define a cavity, with a spout coupled to at least one of the front panel and the back panel, the spout having an opening providing communication into the cavity, wherein,
- at least one of the front panel and the back panel are formed, at least partially from a film comprising:
- a first layer and a second layer, the first layer having an outer surface and an inner surface, and the second layer having an outer surface and an inner surface, the inner surface of the first layer laminated to the outer surface of the second layer to form a two layer laminate,
- the first layer further comprising a base comprising polyethylene terephthalate, with at least one of the outer surface and the inner surface having a barrier layer disposed thereon;
- and
- the second layer comprising a coextrusion having a core layer comprising an ethylene vinyl alcohol with an outer upper layer comprising linear low density polyethylene and an outer lower layer comprising linear low density polyethylene.
