PURPOSE:To carry out complete sealing in the middle of a bag and manufacture a bag with a holding hole in a space just under an opening section by applying an adhesive in the form of a belt from one end to the other end in parallel with the opening section on a proper position under the opening section on one surface of a sheet to form the inside of the bag, overlapping another sheet thereon and side sealing crossing over the belt of the applied adhesive. CONSTITUTION:A long polyethylene sheet 1 is folded into two, and side seal 2 is applied. A bag 3 is manufactured by cutting, and an adhesive 4 is applied on the surface to form the inner side of the bag under and in parallel with an opening section 5, over which a tape 6 to work as peeling paper is placed. A thin propylene sheet is used as peeling paper just as it is or coated with silicone resin. The peeling paper can be cut simultaneously with polyethylene as the material of the bag is heat cut, and not fused to the bag. An adhesive belt can be formed on the way toward the center of the bag and a holding hole 7 can be provided under the opening section. The peeling paper is peeled off the bag manufactured after goods are put therein, and the bag is sealed from one end to the other closely by pressing both inner sides of the bag. |
