ABSTRACT:
A copolyester resin is the polycondensation reaction product of (a) terephthalic acid or a dialkyl terephthalate, (b) at least one alkylene glycol having 2 to 8 carbon atoms, and (c) a dimer diol having as a main component a compound of the following formula (1): ##STR1## wherein R.sub.1 through R.sub.4 are each unsaturated linear organic groups such that the total number of carbon atoms of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is between 22 to 34. Preferably, R.sub.1 and R.sub.2, which may be the same or different, each represent an alkyl group, and R.sub.3 and R.sub.4, which may be the same or different, each represent an alkylene group. The resin of the present invention may be melt-blended with a filler material and formed into a film by suitable film-forming techniques. The film is especially advantageous due to its heat-sealing and mechanical properties.
