Abstract

PURPOSE:To improve ventilation of a bag seal portion and prevent the inward entry of bacteria into the bag after sterilization by providing a bag opening portion with a plurality of elongated swollen portions in the bag opening direction, with top side film and back side film held in a contacting overlap therebetween and with partially heating and fusing portions in a series of swollen portions. CONSTITUTION:A bag opening portion 3 of a bag 1 is provided with a plurality of elongated swollen portions 4 in the bag opening direction of the bag opening portion which is formed into a continuously wavy configuration in a swelling manner widthwise of the bag opening, with top side film 3a and back side film 3b held in a contacting overlap. The top side film 3a and the back side film 3b are fused by partially pressing the swollen portions 4 in a series of the swollen portions 4, whereby fused portions 5 are formed and arranged in a pattern. More specifically, the fused portions 5 are two flat portions which are pressed and fused at two places lengthwise on the pairs of the adjoining swollen portions 4a and 4b in such a pattern as to form at least two rows in a series of the swollen portions 4, with a swollen portion 4c left unfused between each pair of fused swollen portions 4a and 4b.
