When blown film is used for specific applications, such as barriers for meat packaging,the control ofindividual layer thickness for the specialty layer is also critical and should be held to tight tolerances. Examples ofthese specialty layers include a sealant layer which has EZ-peel and antifog properties in a 3-layer PE based film and barrier layers (nylon or EVOH) in multilayer coextrusion films. With tight gauge control a more uniform performance of the film is achieved in the field. Aside from the benefits of increased product performance, there is also a significant cost saving to having good gauge. Amidst rising polymer costs and highly competitive markets a processors ability to produce film with uniform thickness has become a necessity. It's no secret that processors spend more By Andrew Erskine The blown extrusion process is used to make single and multilayerfilms that act as starting materials for printing, lamination and converting (PLC). Today's PLC industry demands blown film processors to make both exceptionally flat films that can be converted at high speeds, and large diameter rolls for minimized changeovers.
