Cracked blend of propylene copolymer and E/VA

A new composition for the heat-sealable layer in a retort-sterilizable pouch is disclosed. The new composition is the cracked product of the blend of a poly(propylene-ethylene) copolymer and an ethylene-vinyl acetate copolymer. This composition has improved flow properties and may be extrusion-coate...

Zusammenfassung:	A new composition for the heat-sealable layer in a retort-sterilizable pouch is disclosed. The new composition is the cracked product of the blend of a poly(propylene-ethylene) copolymer and an ethylene-vinyl acetate copolymer. This composition has improved flow properties and may be extrusion-coated onto a metal film substrate at high speeds.
