Abstract
The present disclosure relates to multi-layer film constructions and methods of manufacturing and using the same. The multi-layer film constructions can include a first layer joined to a second layer. The first layer can include one or more abuse resistant materials. The second layer can include a sealant film, which can be a multi-layer film having one or more sealing layers or sublayers. The second layer can also include one or more barrier layers. The multi-layer film constructions can also include score regions, which can be imparted by a laser or other mechanical implement.
Claims20
A multi-layer film construction, comprising:
- a first layer comprising at least one of a polyester, polyamide, or polypropylene;
- and
- a second layer comprising a plurality of sublayers, wherein at least one sublayer comprises a barrier layer and at least one sublayer comprises a sealant layer, wherein the sealant layer comprises a material having a melt index of between about 5 g/1 0 min and about 15 g/1 0 min, between about 6 g/1 0 min and about 12 g/1 0 min, or between about 7 g/1 0 min and about 10 g/1 0 min.
A method of manufacturing a multi-layer film construction, comprising:
- coextruding a plurality of polymeric materials and blowing the coextruded materials to form a multi-layer coextruded blown film layer comprising a barrier layer and a sealant layer, the sealant layer comprising a material having a melt index of between about 5 g/10 min and about 15 g/10 min, between about 6 g/10 min and about 12 g/10 min, or between about 7 g/10 min and about 10 g/10 min;
- and
- joining the multi-layer coextruded blown film layer to a second layer comprising at least one of a polyester, polyamide, or polypropylene.
