Date Aug. 3, 1995Odors and flavors in thermoplastic films and shaped articles may be reduced or eliminated by the addition of an adsorption agent to the thermoplastic. Thermoplastics include ethylene/acid copolymers and corresponding ionomers, and ethylene/acid/acrylate terpolymers and corresponding ionomers. The adsorption agent is a crystalline siliceous molecular sieve, having a framework of tetrahedral oxide units, in which at least 90% of the tetrahedral oxide units are SiO tetrahedra, a pore diameter greater than 5.5 Angstroms and a sorption capacity for water of less than 10% by weight at 25 DEG C. and 4.6 torr.
