(57) [Summary] The present invention has no film blocking, Suitable for pillow packaging, which has good transparency, good slipperiness, excellent low-temperature shrinkage, high tear strength and low-temperature high-sealing strength, and does not burn through the film during heat sealing or heating by a microwave oven. Provide a multilayer film for packaging. SOLUTION: The present invention provides a polypropylene resin and a low-crystalline ethylene-α-layer between both surface layers made of a specific ethylene resin and an intermediate layer made of a specific ethylene resin different from the ethylene resin. At least one adhesive layer made of a resin composition containing an olefin copolymer is formed of at least five layers, and the heat shrinkage in the vertical direction and the horizontal direction at 100 ° C. is 30% or more. The tear strength in both directions is 7 kg / cm or more, And 100g peel resistance under specific heat sealing conditions This is achieved by employing a film having a thickness of / 15 mm or more. |
