Abstract

Extruded polypropylene (PP) sheet is widely used in the production of thin gauge containers for the food and beverage industry using the thermoforming process. In industry there is not a clear understanding of the relationship between the effect of varying extrusion and thermoforming parameters and the resultant changes in end product properties. This paper investigates the effect of parameters such as chill roll temperature and haul off speed during extrusion, and plug speed and sheet temperature during thermoforming on end product properties such as wall thickness distribution, weight and compressive strength. Test results show several parameters have a large effect on end product properties, with greatest variations between different material grades.
