PURPOSE:To provide a polyolefin laminated product with outstanding properties such as heat retention, transparency, pliability, slippage, and anti-cloudiness. CONSTITUTION:A 20 to 120mum thick laminated product consisting of 100 pts.wt. of polyolefin containing polyethelene of lower than 0.910 of density and 20 to 20 pts.wt. of silica with a grain diameter of 5 to 200nm, is subjected to corona electric discharging process. Then an applicable anti-cloudiness agent is applied to the treated laminated product, to obtain a polyolefin laminated product. In addition, a polyolefin laminated product consisting of an ethylene/ vinyl acetate copolymer and polyethyelene of a density of lower than 0.910 and a polyolefin laminated product containing a silicone modified acryl copolymer are available.
