Abstract

PURPOSE: To obtain a container with good transparency by using a hot plate prepared by grinding a surface of the hot plate of a hot plate heating type air pressure heat molding machine with paper puff processing so as to obtain surface roughness of 0.1W2.5μ.
CONSTITUTION: When a polyolefine sheet is subjected to air pressure heat molding by using the above described objective hot plate, because a surface of the hot plate is finished by paper puff processing, a crest point of a ridge part of ridge and valley parts of the ground surface can be made round can be formed into such a shape that a stripe pattern is directed to one direction as well as air sumps between the hot plate surface and the sheet can be reduced and a molded product with good transparency can be obtained.
