Food packaging can be sealed by heat sealing, which requires a heating rod (sometimes heated in the form of pulse), the force of the heating rod to bite, and the time of the heating rod to bite. Under the action of three factors, the heat sealable materials inside the bag mouth are melted and then glued. This form of heat sealing usually has good sealing performance.
Where is the bag seal?
packing bag
That is, before packaging, only one side of the opening is left for packing, and the other three sides have been heat sealed.
Middle sealing bag
It is also called back sealing bag. The opening is the same as the packaging bag, but its seal is on the back, and there is no heat seal on both sides of the bag.
Side sealing bag
Some milk bags and soy sauce bags are formed in this way, with an obvious heat seal on the side.
Barrel bag
There are only upper and lower seals, which are cylindrical, and generally there is no back design. If there is a back design, it needs to be made separately in two documents.
Clamping bag
It is similar to the middle sealing bag, but there are M-shaped recesses on both sides of the bag, and generally there are lining boxes in the bag.
Side seal clamping bag
It is similar to a clip bag, but the seal is not on the back, but on one side of the M clip on both sides.
Tridimensional bag
It is cone shaped with a bottom. The bag can stand upright. Some tea bags are three-dimensional bags.
