Abstract
PURPOSE:To obtain film for sterilizing bag, which is favorably stable with time and sufficiently reliable and stable for medical usage by a method wherein thermoplastic polyolefin resins are coextruded by T-die method on a supporting body made of plastic film in such a manner that one layer is made of colored one. CONSTITUTION:Thermoplastic polyolefin resins are coextruded by T-die method on a supporting body made of plastic film in such a manner that one layer is made of colored one. As the supporting body, transparent plastic film with proper heat resistance and mechanical strength is used and polyester film having a thickness of about 10-25mum is preferable. As the thermoplastic polyolefin resin, polyethylene resin or polypropylene resin can be empolyed. When a colorless clear polyolefin layer is to be formed through coextrusion lamination, colorless clear pellets are applied to a T-die extruder so as to coextrude and laminate thermoplastic polyolefin resin onto the supporting body in such a manner that at least one layer is made of colored one. Accordingly, colored pellets are charged to at least one of two or more extruders for melt extrusion so as to provide a colored polyolefin layer 4, colorless clear polyolefin layer 5 in the order named on the supporting body 1 made of plastic film.
