摘要： Disclosed are void-containing films and shrinkable films which show excellent density reduction that is retained upon exposures to high temperatures. The voiding agents are hollow glass microspheres. The shrinkable films have high shrinkage and retain their low density after processing under conditions of temperature and moisture used in typical recycling processes. The films are useful as for sleeves, labels, laminates and other shrinkable film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations.

摘要： A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1000 to 40,000 ppm (weight by metal) and a polyester polymer present in an amount of at least 40 wt.% based on the weight of the concentrate. Concentrates made with highly modified polyester polymers are easy to compound with transition metals forming less brittle polymer upon melt extrusion. Bottle preforms and oxygen scavenging bottles can be made from these concentrates by combining solid polyester particles, solid polyamide particles, and solid these concentrate particles c into an melt processing zone, forming a melt, and forming an article directly from the melt. The b* color and the L* color and the haze levels of the preforms are improved over the preforms made with liquid carriers instead of solid concentrates. The particles are also advantageously simultaneously dried in a drying zone under conditions effective to at least partially remove moisture from the blend to thereby further improve the b* color and L* color.
