Comparing Processes For Producing Coextrusion Barrier Film
Vol. 33 #1, Summer 2006
Coextruded barrier film is commonly used in a variety of food and non-food packaging applications. A typical structure contains a polyamide (nylon), EVOH or PVDC barrier layer, tie resins and a polyolefin or ethylene copolymer sealant. There are two primary processes for making these films: blown and cast. Each has its advantages and disadvantages. A general comparison of the two processes is given in Table 1.
