摘要:
A multilayer sheet harmless to human beings, having a certain gas-barrier property, and comprising an easily-produced metal film layer and a packaging material made of the multilayer sheet. The multilayer sheet is composed of at least a resin film layer and a metal film layer of magnesium or a magnesium alloy integrally formed on the resin film layer by evaporation, electron beam, or sputtering. Magnesium is harmless to human beings, and therefore such a multilayer sheet can be preferably used as a material of a food or medicine bag.

A fastener bag that is intended to improve content-filling operation efficiency and that is reliably formed with a cut start portion. A fastener bag (1) constructed as a gazette type packaging bag and having a fastener (10) attached thereto that makes this packaging bag openable and closable, the fastener (10) being composed of a male die member (11) formed with a projection (11b) and a female die member (12) formed with a groove (12b) allowing the projection (11b) to freely engage and disengage the groove. And the two members (11, 12) have their bases (11a, 12a) attached to the inner side of one flat surface (2) or side surface (3) so that the projection (11b) and the groove (12b) are opposed to each other. Further, a cut tape (14) is provided between the bases (11a, 12a) for cutting the flat surface (2) into parts for the male die member (11) and the female die member (12).
