Abstract
Films having peel seal layers and/or barrier layers are provided. In a general embodiment, the present disclosure provides a film comprising a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 145° C., a styrene-ethylene-butylene-styrene block copolymer, and an LLDPE having a melting temperature greater than 120° C.
Claims22
A film comprising a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 140° C., a styrene-ethylene-butylene-styrene block copolymer and a linear low-density polyethylene having a melting temperature greater than 115° C.
A film comprising a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 140° C. and an ethylene-propylene rubber modified polypropylene elastomer.
A container comprising:
- a body defined by a film comprising at least one of 1) a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 145° C., a styrene-ethylene-butylene-styrene block copolymer, and a linear low-density polyethylene having a melting temperature greater than 120° C.;
- and 2) a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 145° C. and an ethylene-propylene rubber modified polypropylene elastomer.
A multiple chamber container comprising:
- a body defined by a film, the body including at least two chambers separated by a peelable seal, the film comprising at least one of 1) a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 145° C., a styrene-ethylene-butylene-styrene block copolymer, and a linear low-density polyethylene having a melting temperature greater than 120° C.;
- and 2) a peel seal layer comprising a blend of a polypropylene random copolymer having a melting temperature greater than 145° C. and an ethylene-propylene rubber modified polypropylene elastomer.
