A heat-bondable sheet material comprising a support carrying about 5 to 100 g/m2 of an adhesive composition comprising 100 parts by weight of polyethylene having a melt index of about 0.2 to 50 and a molecular weight of at least about 22,000, per about 5 to 45 parts by weight of a terpene resin having a softening point of about 60* to 120*C. The support is generally a textile fabric and the product can be bonded to a fabric as a lining or interlining merely by ironing with a flatiron, being securely attached so as to withstand laundering and dry cleaning.
