<p>PROBLEM TO BE SOLVED: To obtain the subject composition giving excellent mold release effect in injection molding without lowering of resistance to stress cracking by containing a specific high-density polyethylene resin and aliphatic acid dialkanolamides in a specific ratio. SOLUTION: This composition contains (A) 100 pts.wt. of a high-density polyethylene resin having 3-50g/10min melt flow rate (at 190 deg.C, under 21.18N) and (B) 0.05-1.00 pt.wt. of aliphatic acid dialkanolamides. The component A is, e.g. a crystalline ethylene homopolymer, a crystalline ethylenic copolymer of ethylene and propylene or ethylene and butene-1 or their mixture in using ethylene as a main component (containing >=50wt.% of ethylene unit) and preferably has 0.941-0.970g/cm<3> density. Preferably, the component B is diethanolamide laurate, etc. The composition can comfortably be applied to an injection molded product for a vessel of pickles of vegetable, meat or fish, etc.</p> |
