RECYCLABLE FILM AND PACKAGING

A recyclable film contains a base film and a sealant. The base film has at least one layer containing a polar polymer and at least one layer containing a polar polymer compatibilizer. Additionally the base film has been oriented and annealed such that it exhibits free shrink of less than 10% in both...

Zusammenfassung:	A recyclable film contains a base film and a sealant. The base film has at least one layer containing a polar polymer and at least one layer containing a polar polymer compatibilizer. Additionally the base film has been oriented and annealed such that it exhibits free shrink of less than 10% in both the machine direction and the transverse direction when, exposed to heat of 90° C. This film has advantages over prior recyclable films in efficient film manufacturing, high quality package production and superior package performance.
