Abstract
It is the side envelope plane overlap joint packaging bag for manufacturing raw material that the utility model is related to a kind of with thin-film material.The packaging bag is made of molding two layers of the membranous wall of wound membrane material, and two layers of membrane width direction edge is linked together, wherein having longitudinal sealing on a tunic wall, length direction both ends have across seal；Longitudinal sealing is directly overlapped by two ends of wound membrane material side to be bonded, i.e., the medial surface of one of end is bonded closing with the lateral surface of another end, and binding face is made to be generally in a plane with the tunic wall.By the way that directly overlapped, mode formed the utility model that the longitudinal of packaging bag seals, not only reduce waste of material, and keep longitudinal sealing substantially equal with membranous wall, improve surface smoothness, while improving presentation quality, it is also beneficial to reduce the transporting resistance of product in the production line, improves the reliability of packaging production.
Description
Technical field
It is the side envelope plane overlap joint packaging bag for manufacturing raw material that the utility model is related to a kind of with thin-film material.
Background technology
The manufacture of normal packet pack is usually using plastics wound membrane as raw material, by packaging facilities, by wound membrane width direction both sides
Bending fold simultaneously closes an opposite side, forms the double-deck membranous wall, then by the rear cut-out closed at both ends of length direction, formed independent
Packaging space.Therefore its structure is usually made of two layers of membranous wall, and two layers of membrane width direction edge is linked together, wherein a tunic
Closing is mutually bonded by two sides of wound membrane in the middle part of wall, forms longitudinal sealing, the membranous wall at length direction both ends bonds enclosed shape
At two across seals.In existing structure, longitudinal sealing is typically that will be bonded to each other on the inside of the both side ends of wound membrane, then pass through
The modes such as seal bond composition, therefore longitudinal edge sealing protrudes from except membranous wall, and such structure not only increases material
Consumption, and cause packaging bag surface smoothness bad, affect its presentation quality.
Invention content
Technical problem to be solved by the utility model is to provide the good side envelopes of a kind of saving material, flat appearance degree
Plane overlaps packaging bag.
The side envelope plane overlap joint packaging bag of the utility model is made of molding two layers of the membranous wall of wound membrane material, two layers of membranous wall
Widthwise edges are linked together, wherein having longitudinal sealing on a tunic wall, length direction both ends have across seal；It is described
Longitudinal sealing is directly overlapped by two ends of wound membrane material side and is bonded, i.e., the medial surface of one of end with it is another
The lateral surface fitting closing of a end, makes binding face be generally in a plane with the tunic wall.
The suppending hole for facilitating suspension is provided at the across seal of described one end.
The suppending hole is round, heart-shaped or other are close-shaped.
The across seal outer end has arc-shaped corner.
It is provided with tearable mouth on the side of the across seal of described one end.
By the way that directly overlapped, mode formed the utility model that the longitudinal of packaging bag seals, and not only reduces waste of material,
And keeps longitudinal sealing substantially equal with membranous wall, improve surface smoothness, while improving presentation quality, be also beneficial to subtract
The few transporting resistance of product in the production line, improves the reliability of packaging production.
Description of the drawings
Fig. 1 is the side planar structure schematic diagram of the utility model embodiment；
Fig. 2 is the cross section structure schematic diagram of the utility model embodiment；
Fig. 3 is the A partial enlargement structural representations of Fig. 2.
Specific implementation mode
As shown, side envelope plane overlap joint packaging bag is made of molding two layers of the membranous wall of wound membrane material 1, two layers of membranous wall
Widthwise edges are linked together, wherein having longitudinal sealing 2 on a tunic wall, length direction both ends have across seal 3；Institute
State longitudinal sealing and directly overlapped by two ends of wound membrane material side and is bonded, i.e., the medial surface of one of end with it is another
The lateral surface fitting closing of one end, makes binding face be generally in a plane with the tunic wall.The wherein transverse direction of one end
It seals and is provided with the suppending hole 4 for facilitating suspension at 3, suspension hole shape is heart.Across seal outer end has arc-shaped corner.Wherein
Tearable mouth 5 is provided on the side of the across seal of one end.
