| 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. |
