Title:
ALUMINUM FOIL FOR PACKAGING
Document Type and Number:
Japanese Patent JP3590022
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an aluminum foil for packaging wherein a knob section is formed without performing heat-sealing even when there is a slight slip the formation of the knob section, and an opposite surface is exposed.
SOLUTION: For this aluminum foil for packaging on one surface, a heat- sealing agent layer is formed. In this case, a non-bonding section A in order to form the knob section to unseal the packaging is formed at one section on the opposite surface. Then, a non-bonding section B is formed at an approximately corresponding section on the other surface for the aluminum foil for packaging. Thus, the aluminum foil for packaging can surely form the knob section even when the formation of the knob section by folding in order to unseal an individual package is more or less inaccurate, the knob section can be surely formed, and the unsealing becomes easy.
