A packaging film and a method of manufacturing a packaging film

摘要

The present invention provides a packaging film including: (a) an outer layer comprising an ionomer to provide thermal resistance; and (b) an inner layer comprising a polymeric material having a sealing temperature lower than the sealing temperature of the outer layer. The invention also provides a method of making a paCkaging film as described above, which includes the steps of (a) co-extruding a first layer comprising an ionomer and a second layer comprising a polymeric material having a sealing temperature lower than the first layer; and (b) cooling the co-extruded film. A method of packaging a food product is also provided.
