摘要： A film includes a core layer including a polymer such as nylon 6, nylon 66, nylon 6,66, and/or polyamide elastomer; first and second intermediate layers including polymeric adhesive; a first outer layer including ethylene/alpha olefin copolymer having a density of less than 0.940 grams/cubic centimeter; and a second outer layer including heat sealable polymer such as (1) ethylene/alpha olefin copolymer having a density less than 0.921 grams/cubic centimeter, (2) ethylene/vinyl acetate copolymer, (3) ethylene/alkyl (meth)acrylate copolymer, (4) ethylene/(meth)acrylic acid copolymer, and/or (5) ionomer. The film has good resistance to tear, and good resistance to impact, making it useful for packaging coins and other objects. A bag made from the film, and an article such as a sealed bag filled with coins or other objects, are also disclosed.
摘要翻译：膜包括包含聚合物如尼龙6，尼龙66，尼龙6,66和/或聚酰胺弹性体的芯层; 第一和第二中间层包括聚合物粘合剂; 包括密度小于0.940克/立方厘米的乙烯/α-烯烃共聚物的第一外层; 和（2）乙烯/乙酸乙烯酯共聚物，（3）乙烯/（甲基）丙烯酸烷基酯共聚物，（3）乙烯/（甲基）丙烯酸烷基酯共聚物，，（4）乙烯/（甲基）丙烯酸共聚物和/或（5）离聚物。该片具有良好的耐撕裂性，抗冲击性，使其适用于包装硬币和其他物品。还公开了由薄膜制成的袋子以及填充有硬币或其他物体的诸如密封袋的物品。
