| 摘要 |
The present invention provides a film for packaging cells. The film for packaging cells includes a first substrate layer; a metal layer which is placed inside the first substrate layer; a second substrate layer which is placed inside the metal layer; and an adhesive layer which is placed between the metal layer and the second substrate layer. The adhesive layer includes one or more types of acid-denatured resin among a group of acid-denatured polyester resin, acid-denatured polyamide resin, and acid-denatured polyolefin resin having a melting temperature (Tm) between 65 and 75°C. The film for packaging cells has high strength, adhesion stability, adhesion durability (Al/heat sealing layer), gas barrier properties, sealability, pin-hole resistance, chemical stress resistance, and high barrier properties. |
