An apparatus and associated method of separating mixed fragments of different plastic materials, in which the materials to be separated are capable of carrying electrostatic charges of opposite polarities. The mixed charged fragments are given an induced electrostatic charge and are then exposed to electrostatic field of opposite polarities where they are separated by being allowed to migrate toward their respectively oppositely charged fields. The separated material fragments are then collected.

Electrostatic separation of plastic materials

This relates to a method of forming a thermal/collapse-resistant highly oriented polyester container for use in hot fill applications. In accordance with the method of a polyester preform is reheated and then placed in a blow mold cavity whereat the preform is distended to match the blow mold cavity to form an intermediate article including a container having an oriented end unit receiving finish of a diameter materially greater than the diameter of the preform. The method is characterized in that in providing the preform the composition of the polyester, the draw ratio during distending of the preform and reheat conditions are all controlled to provide a container with a sidewall and finish density in the range of 1.350 to substantially but less than 1.370 grams/cubic centimeter.
