Abstract
PURPOSE: To provide a sealed pacakage, wherein an article can be packaged using packaging material excellent in properties, such as welderbility at low temperatures, sliding ability, releasability from a hot plate and destaticizing ability, which are demanded when an article is packaged by an automatic pacakaging machine.
CONSTITUTION: An article is packaged by heat-bonding ends of a lminated film comprising at least two layers, in which at least one surface of the substrate of copolymer contaning polypropylene includes a polymer mixture containing 20 to 85% by weight of ethylene-propylene copolymer and 80 to 15% by weight of copolymer of monomers (excluding butene) containing butenically and ethylenically unsaturated bonds. Alternatively, a package having good sealing properties is formed which comprises such a surface of the substrate allowed to include 100 parts by wieght of copolymer mixture containing 20 to 85% by weight of ethylene-propylene copolymer and 80 to 15% by weight of copolymer of monomers (excluding butene) containing butenically and ethylenically unsaturated bonds and 0.01 to 0.5 parts by weight of silicone oil.
