Title:
SOFT CONTAINER
Document Type and Number:
Japanese Patent JP3751149
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a container which is excellent in heat resistance and impact resistance at low temperature and is also easy to dispose by molding a polypropylene-based oriented film having a specific thickness and having specific physical properties.
SOLUTION: The soft container is formed by molding a polypropylene-based oriented film wherein thickness is 80 to 300 μm, shearing moduli in a film flowing direction and in a direction at the right angle to the film flowing direction are both 2500 N/mm2 or less, and a shearing modulus in at least one direction is 1300 to 2500 N/mm2. With the polypropylene-based oriented film having both such thickness and shearing modulus, a container can be obtained, which is provided with moldability, heat resistance and impact resistance at low temperature, and also has a nature easy to squash but difficult to recover in form if squashed and which is excellent in disposability.
