Abstract
A composition which is polyolefin-based includes polyolefin; from 0.1 to 5 parts by weight of lubricating agent per 100 parts by weight of the polyolefin; and from 0.05 to 2 parts by weight of zeolite per 100 parts by weight of the polyolefin, which zeolite is a crystalline aluminosilicate having a water adsorptivity not exceeding 10% of its weight, at 25.degree. C. and at a water vapor partial pressure of 4.6 torr, and having an Si/Al molar ratio in the crystal lattice of at least 35.
