摘要： PROBLEM TO BE SOLVED: To obtain a polypropylene film constituting a thermoforming sheet to be molded into a tray for a side dish and the like which has good thermoforming properties and good adhesion to a base material sheet and gives a molded article after thermoforming having good gloss and no deformation. SOLUTION: The uniaxial stretched polypropylene film for a thermoforming sheet comprises a polypropylene based resin having an MFR of 0.3-12.0 g/10 min and is heat-set after stretching the film in the lengthwise direction (MD direction) 3 to 5 times. The polypropylene based resin is a polypropylene homopolymer resin, an ethylene-propylene random copolymer resin having an ethylene content of ≤2.0 wt.% or a mixed resin having an ethylene content of ≤2.0 wt.% obtained by mixing a polypropylene homopolymer resin with an ethylene-propylene random copolymer resin.

摘要： PROBLEM TO BE SOLVED: To provide a heat-resistant transparent container for storing food for sale, which is highly heat-resistant enough to resist against heating in a microwave oven and retort sterilization and also is excellent in transparency.
SOLUTION: The heat-resistant transparent container is cooled through a primary stretch heat-setting step of heating an A-PET (amorphous polyethylene terephthalate) sheet, primarily stretching and thereafter primarily heat-setting, and a secondary stretch heat-setting step of hot-forming the primary stretched A-PET sheet prepared in the primary stretch heat-setting step in a die of a hot-forming machine, secondarily stretching by molding, and thereafter secondarily heat-setting in the same die.
