摘要： A coextruded heat sealable film made with nonoriented polyester and a heat seal layer comprising about 50% to about 80% of a copolyester and about 20% to about 50% of an olefin polymer is disclosed. In one preferred embodiment the polyester base layer includes from about 1% to about 5% of a polyolefin, LLDPE being preferred; and in another preferred embodiment the polyester base layer comprises a resin which is a nonoriented film form has a tensile strength of 7,000 psi or more. The heat sealable film can be laminated with aluminum foil, paper, etc. to form a composite which is heat sealable, useful in pouches and lidding stock. The heat seal layer using about 30% to about 40% LLDPE as the olefin polymer is particularly useful when the film is laminated to aluminum foil and heat sealed as lidding stock to crystallized CPET trays.
摘要翻译：公开了一种由非取向聚酯制成的共挤出的可热封薄膜和包含约50％至约80％的共聚酯和约20％至约50％的烯烃聚合物的热封层。在一个优选实施方案中，聚酯基层包含约1％至约5％的聚烯烃，优选LLDPE; 并且在另一个优选实施方案中，聚酯基层包括非取向膜形式的树脂，其拉伸强度为7000psi或更大。可热封膜可以与铝箔，纸等层压，以形成可热封的复合材料，可用于袋和盖子料。使用约30％至约40％的LLDPE作为烯烃聚合物的热封层在将薄膜层合到铝箔上并作为封盖料加热密封至结晶的CPET塔板时是特别有用的。

摘要： A nonoriented, heat sealable, coextruded, moisture barrier film is disclosed. This film has a base layer ("A") of polypropylene homopolymer, polypropylene copolymer or combinations thereof, a heat sealant layer ("C") of polyester/copolyester or blends thereof and a tie layer ("B") of modified polyethylene homopolymer, modified polyethylene copolymer, modified polypropylene homopolymer, modified polypropylene copolymer, an unmodified polyethylene copolymer or combinations thereof between the base layer ("A") and the heat sealant layer ("C"). This film has three layers ("ABC") or five layers ("CBABC"). This film exhibits a very broad heat seal range and has a moisture vapor transmission rate of from about 0.20 to about 1.0 g/100in.sup.2 /24 hr. This film has a wide variety of applications as a packaging film including such demanding uses as the inside of a microwave popcorn bag. This film significantly improves the shelf life of microwave popcorn compared to conventional films used for this product. This film also exhibits excellent heat seal properties to itself as well as a wide variety of diverse substrates.

摘要： Bales of unvulcanized rubber, vulcanized rubber or compounding ingredients for unvulcanized rubber are packaged in film or bags made from syndiotactic 1,2-polybutadiene (1,2-SBD) containing at least one antiblock agent additive and at least one slip agent additive. Coextrusion can be used to manufacture bags or film having two or more layers where only the inside layer is heavily loaded with antiblock additives and the outside layer contains only a minimal amount of antiblock additives with both layers containing slip agents. The use of 1,2-SBD serves to eliminate the problems of incompatibility and disposal encountered in the prior art and provides film and bags having superior puncture and tear resistance when compared to a conventional material such as polyethylene.
