ABSTRACT:
Cold-stretched products comprising a propylene-based resin composition obtained by mixing
(A) a polymer consisting mainly of propylene units, in a proportion of not more than 92% by weight and not less than 50% by weight,
(B) a polymer consisting mainly of butene-1 units or an ethylene-.alpha.-olefin copolymer having a softening point of 95.degree. C. or lower, in a proportion of not more than 47% by weight and not less than 5% by weight,
(C) a tackifier in a proportion of not more than 25% by weight and not less than 3% by weight, the sum of the proportions being 100% by weight; and a process for producing said cold-stretched products.
