Abstract
A process for packaging normally tacky amorphous polyolefins, and other materials having similar melt viscosities, is provided. The process entails flowing a heated material into a molded polyolefin container having a minimum wall thickness of about 0.1 mm to less than 0.24 mm at a temperature above the melting point of the container, followed by slowly cooling the filled container. The process is conducted at ambient conditions without the use of cooling fluids.
