摘要： This invention concerns blends of poly(ethylene terephthalate), poly(ethylene naphthalate) and a compatibilizing amount of a copolyester which comprises (1) an acid component comprising repeating units of from about 10 to about 20 mole % terephthalic acid and about 80 to about 90 mole % naphthalenedicarboxylic acid, and (2) a glycol component comprising repeating units of ethylene glycol. Clear containers containing less than 10% haze produced from such blends are useful for a variety of packaging applications, particularly hot-fill food and beverage containers where good barrier and clarity are needed.

摘要： This invention relates to polyester/plasticizer blends which are useful as heat-shrinkable films or sheet in low temperature shrink packaging applications. The plasticizer is injected into the melt of the polyester. The plasticizer lowers the glass transition temperature, on-set temperature and shrink rate of the polyester. Film or sheet produced by the polyester/plasticizer blends is clear.
