<p>PURPOSE:To improve the handling property and operatability by a method wherein a bag main body is formed by sealing four edges of two sheets of a polyethylene film group laminate under a put together condition, and also, handle parts and a pouring in/out port are provided on the bag main body. CONSTITUTION:A bag body 1 is equipped with a bag main body 4 and pouring in/out port 5, and in addition, is equipped with handles 6. The bag main body 4 is formed by sealing four edge seal parts 3 under a condition wherein two sheets of a PE film group laminate 2 consisting of a plurality of polyethylene(PE) films are put together. A pair of the handles 6 are provided at both sides of the edge of the bag body 1 wherein the pouring in/out port 5 is located. The reason why the handles 6 are provided on the edge wherein the pouring in/out port 5 is located is that if the inside of the four edge seal parts 3 on the opposite edge is cut, a residual liquid remaining in the bag body can be easily discharged. Also, the reason why a pair of the handles are formed is that the stability is improved when the bag body is suspended to discharge the residual liquid.</p> |
