Film and sheet extrusion systems supplier Macro Engineering & Technology Inc. (Canada) has added the option of individual layer gas foaming to its barrier blown-film coextrusion lines. Macro’s blown-film coextrusion systems are used to produce high-barrier films up to 11 layers and up to 3 m wide. The films produced are most typically used in food and medical packaging applications. The individual layer foaming option allows processors to create a wider range of products by manipulating different foamed layer combinations within the coextruded film structures. The configuration of the line allows it to be operated with or without foam injection, allowing the film producer to easily switch between foamed films and conventional multilayer film production without changing machinery.
