POLYETHYLENE THEREPHTHALATE ARTICLES HAVING DESIRABLE ADHESION AND NON-BLOCKING CHARACTERISTICS, AND A PREPARATIVE PROCESS THEREFOR

摘要

Surface treated articles of polyethylene terephthalate (PET) are disclosed having low self-adhesion and high bondability to other surfaces. The articles comprise oriented PET and about 100-5000 ppm of a particulate additive uniformly dispersed therein. The additive is chemically inert to PET and has an average particle size of about 0.03 to 0.6 micrometers. A process for the preparation of such articles is also disclosed.
