<p>PURPOSE:To obtain a container body which lessens a temp. delevation, has the high strength to dropping from a high place and has an excellent release property, low moisture vapor transmission rate and good slip by using a PP resin, aluminum powder or aluminum paste and PE resin or ethylenic copolymer resin to form the above-mentioned body. CONSTITUTION:The above-mentioned container body is formed by using 60-99.9wt% PP resin having 8-70g/10min melt index, 0.89-0.92g/cm<2> density, >=1.8kg.cm/cm notched Izod impact strength at 20 deg.C and >=220kg/cm<2> tensile yield point strength, 0.1-15wt% aluminum powder or aluminum paste and 0-39.9wt% PE resin or ethylenic copolymer resin. The resin having such properties is obtd. by, for example, incorporating a suitable ratio of an org. or inorg. nucleus forming agent into the PP resin.</p> |
