  • Publication number: 20080237316
    Abstract: A plurality of air relief holes 18 for removing air in a bag are formed in a slit shape at a portion where, when an opening portion of an envelope 10 is sealed by a seating portion 11a, the air relief holes are concealed by the sealing portion and which is an upper end portion of a second back face 14 of the envelope 10. In case that the envelope 10 is inserted between a pair of upper and lower pressure-contacting rollers from its bottom portion, when the envelope 10 passes through between the pair of upper and lower pressure-contacting rollers rotating in a manner sandwiched therebetween, air staying in a bag of the envelope 10 is exhausted from the air relief holes 18 to the outside, so that the envelope 10 is changed in one sheet shape. Thereby, forces acting on upper and lower faces of the envelope 10 from the pair of upper and lower rollers becomes approximately even, so that occurrence of wrinkles on the envelope 10 is suppressed.
