Abstract
PURPOSE: To effectively manufacture three directional bag without lip by a method wherein a bag is vertically sealed with a polimerized film and horizontally done with the length two times as long as that of the vertical direction of each bag and also by a method wherein the vertically sealed portion is cut along therewith and the film is horizontally cut as per each bag size, the bag direction being aligned. CONSTITUTION: A film 1 is vertically folded in two and the front surface 2a and back surface 2b portions of a pattern 2 are polimerized, and then, the sealing portions 3a and 3b vertically continuing between both ends of a film and the pattern 2 are heated to be sealed. With respect to the horizontal sealing, only a portion 4 to which each portion to be a bag 6 is reciprocally adjacent is sealed covering each bag 6. A portion 3a vertically sealed with a polimerized film 1 is cut and the portion to be a bag 6 is divided into four films 1a, 1b, 1c and 1d vertically continuing in the individual line. With respect to the four films 1a, 1b, 1c and 1d, the portion 4 and a portion 5 to which each portion to be a lower end thereof is reciprocally adjacent are horizontally cut. The portions cut as above are categorized into a group having the same aperture direction and all the bag 6 directions are aligned.
