Common soft-packed bags

  Trilateral pocket

  The trilateral seal pocket has two side seams and one top seam pocket, the bottom of which is formed by folding the film horizontally. These bags can be folded or not, and when they are folded, they can stand upright on the shelf.

  One of the variants of a three-sided pocket is to fold the original edge to form a bottom edge and glue it so that it essentially becomes a four-sided pocket.

  Backpack

  Backpacks are also called pillow-shaped bags. They have seams at the back, top and bottom, making them pillow-shaped. Many snack bags are often packed in pillow-shaped bags. The back seams of the pillow-shaped bag form a fishfin-like encapsulation in which the inner layers of the film are placed together and the seams protrude from behind the encapsulated bag. The other type of seal overlaps, where the inner layer of one side is bonded to the outer layer of the other side to form a flat seal. Because the "fishfin" seal is strong and can be heat sealed as long as the inner layer of the packaging material, it is widely used. The "overlap" seal is relatively not strong and requires the inside and outside of the bag to be heat-sealed, so it is not used much. The top and bottom seals are glued together by the inner material of the bag.

  03

  Folded bag

  Folded bags, also known as fold-in bags and organ bags, are the deformation of the back pack. They are folded in on both sides of the bag to form an M-shaped bag. If the M-shape is not symmetrical, it is also called a trapezoidal folded bag.

  04

  Four-sided bag

  Four-sided pockets are usually made of top, sides and bottom seals of two (rolled) materials. Compared with the previously mentioned bags, it is possible to use two different types of plastic resin materials to make four-sided front-bonded pockets if they can be bonded to each other. Four-sided pockets can be made into various shapes, such as heart or oval.
