EASY-TO-UNSEAL PACKAGING BAG

An easy−to−unseal packaging bag capable of being realized only by a rather simple processing without lowering the strength of the sealed portion of the packaging bag and the strength of the packaging bag itself and easily unsealed by hand without providing the possibility of peeling−off of the sealed portion in a distribution stage, wherein two sheets of front and rear side films are sealingly stuck to each other at the peripheral parts thereof, the linear cuttability of the front side film in one direction is larger than that of the rear side film in either direction, and a processing part capable of starting the cutting of the front side film along one direction is provided at a part of the peripheral parts intersecting the one direction.

L'invention concerne un sachet d'emballage facile à ouvrir, pouvant être réalisé par un seul processus plutôt simple, sans que la résistance de la partie scellée de ce sachet d'emballage et la résistance du sachet d'emballage lui-même ne soient diminuées, et s'ouvrant facilement à la main sans risque de pelage de la partie scellée au cours d'une phase de distribution. Selon cette invention, deux feuilles de films avant et arrière sont collées ensemble, de façon étanche, au niveau leur parties périphériques. L'aptitude au découpage linéaire du film avant dans un sens est supérieure à celle du film arrière dans l'autre sens et une partie permettant de débuter le découpage du film avant dans un sens est formée à un endroit des parties périphériques croisant le premier sens.
