ABSTRACT:
The first invention provides a multi-layer film comprising (A) a low density polyethylene-based resin layer, (B) a polyolefin-based resin expanded layer and (C) a high density polyethylene-based resin layer.
The second invention provides a package comprising (I) an article to be packaged, (II) the multi-layer film of the first invention, said multi-layer film being used in packaging the article in such a manner that the low density polyethylene-based resin layer is in contact with the article, and (III) a buffering material being used to fix the article.
The multi-layer film of the first invention is excellent in buffering properties, tensile strength, tear strength, impact strength and stiffness, and further has good frictional charcteristics and good pearl-like appearance.
With the package of the second invention, an article can be efficiently protected during its storage and transportation, and thus an easily scratchable article can be effectively protected.
