TRANSPARENT POLYPROPYLENE CONTAINER AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a container which can be substituted for a container made of a polystyrene or polyester raw material by improving the transparency and rigidity of a transparent polypropylene container. SOLUTION: A method for producing a transparent polypropylene container in which a sheet in which 0.01-1 wt.% of a nucleus forming agent is added into a resin containing polypropylene as a main component is vacuum-formed at the melting peak temperature of the sheet measured by a differential calorimeter or below, under an air pressure of 3-50 kg/cm2, and at a plug drawing speed of 250-1000 mm/see and the container obtained by the method are provided.
