摘要： PURPOSE:To enhance heat-resistant oxidative deterioration properties and corrosion resistance, in a polyolefin coated steel material obtained by coating a steel material whose surface is subjected to substrate treatment through an adhesive, by selecting a plurality of specific materials as polyolefin and the adhesive to use them. CONSTITUTION:For example, a silica type chromate film 2 or an epoxy primer film 3 is formed on the surface of a steel material 1 to apply substrate treatment to the steel material l and polyolefin 5 is applied to the treated surface of the steel material 1 through an adhesive 4. In this case, as polyolefin 5, an ethylene/propylene random copolymer mixed with 5-50wt.% of polydimethylsiloxane grafted polyolefin and the others are used. As the adhesive 4, modified matter obtained by modifying 1g of an ethylene/propylene random copolymer with 1X10 -1X10 mol of maleic anhydride and the others are used.

摘要： PURPOSE:To obtain excellent tensile strength, tear strength, heat resistance and flexibility by laminating a plurality of OPP films with each other by a low-density polyethylene adhesive resin to produce a composite film. CONSTITUTION:A plurality of oriented polypropylene films are subjected to sandwich lamination by use of a low-density polyethylene adhesive resin to obtain a laminate of the stretched polypropylene films. A composite film having a most excellent bond strength between layers and excellent mechanical strength and heat resistance can be obtained when a biaxially oriented thin polypropylene film is used as the polypropylene film and a mixture of a low-density polyethylene obtained by a high-pressure method to have a density of 0.91-0.93 and a melt flow rate of 5-20 with an ethylene/alpha-olefin copolymer is used as the adhesive resin. The composite film is rich in flexibility, and is uninjurious to the human body.
