    摘要: An improved apparatus and method for calendering of thermoplastic material are disclosed. An endless belt is interposed between the calendered material and the last calender roll which belt conveys the thermoplastic calendered sheet around the last calender roll and toward the stripper roll. The thermoplastic calendered sheet does not come into contact with the final calender roll surface. After cooling the film should strip easily off the endless belt. Consequently, problems originating in sheet adhesion to the final calender roll will be reduced if not eliminated.

    摘要: A melt-blended polyethylene/COP composition suitable for making optically clear films with low coefficients of friction includes from about 70 to about 98 weight percent of a polyethylene resin and from about 2 to about 25 weight percent of a first COP resin component, the first COP resin component having a weight average molecular weight of from about 0.5 kg/mol to about 50 kg/mol and being present in an amount effective to increase the relative slip value of films made from the composition as compared with a like film made from the polyethylene resin alone.

    摘要: The present invention relates to a heat-sealable film which consists essentially of a cycloolefin copolymer (COC), the glass transition temperature (Tg) of the COC being within the range from 30 to 55° C. The film or sheet has excellent low temperature heat-sealing properties and processing characteristics. The film may be free standing or laminated to other thermoplastic polymer film or films at low temperatures. Alternatively, a COC polymer with Tg in the range 30 to 55° C. may be coextruded with other thermoplastic polymer or polymer films in a coextrusion process to form a heat sealable film. The film of the invention is suitable for packing foods or other consumable items.
