A polyester resin composition is calendered to produce a film or a sheet. The polyester resin composition is a polyester having a crystallization half time from a molten state of at least 5 minutes combined with an additive for preventing sticking of the polyester to calendering rolls.

Polyester resin compositions for calendering

A heat sealable packaging film producing a peelable seal is formed from a blend of 99 to 75 weight percent of a copolyester and 1 to 25 weight percent of an epoxy-containing impact modifying polymer. The copolyester has a diacid component of at least 50 mole percent terephthalic acid, naphthalenedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, or mixtures thereof and diol component of about 90 to 35 mole percent ethylene glycol and 10 to 65 mole percent of at least one of diethylene glycol or 1,4-cyclohexanedimethanol.
