Abstract

La présente invention porte sur un sac d'emballage d'aliments qui est utilisé pour stocker temporairement des aliments réfrigérés ou congelés. En particulier, dans un état où une feuille d'isolation thermique, pour maintenir l'isolation thermique du sac, est stratifiée, et dans un état où une fermeture à glissière est montée pour ouvrir ou fermer le sac, la présente invention empêche une poignée formée sur le côté supérieur de la fermeture à glissière de se déchirer, et empêche la fermeture à glissière de s'ouvrir dans le cas de l'utilisation de la poignée, ainsi assurant une commodité d'emploi. La présente invention porte également sur la fabrication du sac qui est rendue plus facile. De plus, du fait que la surface inférieure du sac est formée de façon à être largement étalée, une force d'adhérence est facilement communiquée pendant la fabrication, l'aspect externe est excellent et une couche de surface constituant un sac d'emballage est également protégée.
