Abstract
The invention discloses an automatic production equipment, which includes a folding part, a pair of opening parts, a transverse sealing part and a vertical sealing part. An opening is defined between a first edge of a film layer and a second edge of the film layer, and the pair of opening parts open the opening between the first edge of the film layer and the second edge of the film layer for an object to be inserted through the opening. The transverse sealing portion forms a first transverse heat-sealing edge and a second transverse heat-sealing edge on the folded film layer, and the vertical sealing part forms a vertical heat-sealing edge on the folded film layer.
Claims8
A packing bag, comprising:
- a film layer having a first transverse sealing edge, a second transverse sealing edge, a longitudinal sealing edge and a folding line, the film layer being folded along the folding line, the longitudinal sealing edge being opposite to the folding line, the first transverse sealing edge being connected to the longitudinal sealing edge and the folding line, the second transverse sealing edge being connected to the longitudinal sealing edge and the folding line and opposite to the first transverse sealing edge, the first transverse sealing edge, the second transverse sealing edge, the longitudinal sealing edge and the folding line collectively forming an accommodating space, the accommodating space being for accommodating an object;
- at least one airbag disposed on the film layer, the at least one airbag transitioning from a flat state to an inflated state by being inflated;
- wherein the film layer further has a first film edge and a second film edge, after the film layer is folded along the folding line, the first film edge is corresponding to the second film edge and the first film edge and the second film edge define an opening, and the longitudinal sealing edge is for sealing the first film edge and the second film edge, so as to seal the opening;
- and
- wherein the second transverse sealing edge and the longitudinal sealing edge are formed after the first transverse sealing edge is formed and after the object has been placed into the accommodating space.
A packing bag, comprising:
- a film layer having a first transverse sealing edge, a second transverse sealing edge, a longitudinal lug sealing edge, a first folding portion and a second folding portion, the first transverse sealing edge and the second transverse sealing edge being opposite to each other in a first horizontal direction and extending in a second horizontal direction perpendicular to the first horizontal direction, the first folding portion and the second folding portion being opposite to each other in the second horizontal direction and extending in the first horizontal direction;
- wherein the longitudinal lug sealing edge is connected to the first transverse sealing edge and the second transverse sealing edge, and located between the first folding portion and the second folding portion in the second horizontal direction;
- the first transverse sealing edge, the second transverse sealing edge, the longitudinal lug sealing edge, the first folding portion and the second folding portion are collectively forming an accommodating space;
- the accommodating space is for accommodating an object;
- and
- at least one airbag disposed on the film layer, the at least one airbag transitioning from a flat state to an inflated state by being inflated.
