Plastic film stretching line TDO

Marshall and Williams Plastics is a recognized global leader and innovator in plastics orientation and casting equipment. Founded in 1920, Marshall and Williams built tenter frame systems for the textile industry and was the first to adapt this technology to orient plastic film and sheet. Transverse direction orientation of plastic film and sheet is accomplished by heating the web and stretching it in the transverse (or cross) direction on a tenter frame. The tenter frame consists of two horizontal chain tracks, on which clip and chain assemblies ride, enclosed in an oven. Typically three heated zones: pre-heat, stretch, and anneal Adjustable rail widths Advanced clip design for a wide range of applications Designed to process a wide range of materials, widths & thicknesses Used in film, sheet, netting or nonwovens Commonly processed materials include PS, PP, PET, PLA, PTFE, PETG, PVDF, and others
