<p>PURPOSE:To provide a refuse bag which has good bottom seating, high strength and good refuse storage and is convenient to carry. CONSTITUTION:A polyethylene basic bag with central folded parts 6, 7 is folded into two halves with regard to its axis C to seal one open end part 5 by means of thermal fusion. The first cut part 11 is formed at a surface on the opposite side to the axis C of the other open end part 4 to form the second cut part 12 at the axis C. It is thus possible to form a stable bag bottom with high strength.</p> |
