<p>PURPOSE: A multi layered wrapping film is provided to be used to wrap food and non-food so a wrapped material as to have a projected metal coated material and the excellent sealing intensity by having the excellent mechanical characteristic and the isolating characteristic. CONSTITUTION: A multi-layered film contains a base material of film having an a), a b), a c), and a d) layers. The base material of film comprises of a metal laminated material of aluminum existed on the surface of an EVOH(ethylene vinyl alcohol) copolymer and a copolymer composed of the alpha, beta-ethylene unsaturated carboxyl acid of 10-35wt%, and the ethylene, the alkyl acrylate, the alkyl methacrylate, the acrylonitrile or their mixture of 65-90wt%, and contains a low temperature sealing coated material(LTSC) directly stuck on the exposed surface of metal layer without a primer. The film is used to a wrapping usage when the metal layer is protected with the sealing coated material having the fine sticking force of metal and the high sealing intensity.</p> |
