PURPOSE: To provide a laminated film which has excellent transparency, perfume barrier properties, heat resistance, moldability and low-temperature sealability as a food packaging film. CONSTITUTION: A laminated film is obtained by orienting a laminated raw fabric film made of a polyamide resin layer containing aromatic polyamide, and a resin layer containing 0-50 pts.wt. of one or more types selected from a group consisting of 50-100 pts.wt. of linear low-density polyethylene, branched low-density polyethylene, ethylene-vinyl acetate copolymer and polyethylene elastomer by an orientation magnification of 2-6 times. Accordingly, the layer formed by using the linear low-density polyethylene has excellent seal strength and admixture sealability. The branched polyethylene is mixed to largely improve the moldability, low-temperature sealability at the time of forming the film. |
