The advantages of eight edge sealing bag and the production process

Eight-sided sealing bag is the rise of the bag type in recent years, evolved from the self-supporting bag, hereinafter referred to as (eight-sided sealing bag) ") its advantages are standing stable, eight-sided sealing bag space capacity, the same size, is conducive to protect the product from extrusion deformation. Compared with other bag layout modules, the product information is clear and comprehensive, which is conducive to product promotion and sales. The type of eight-sided sealing bag is novel and three-dimensional. Compared with other bag types, it gives a refreshing feeling, attracts attention and is conducive to sales promotion. Add zipper, can increase the reuse of packaging bag.

Eight edge sealing packaging bag material collocation; Generally, BOPPYOPP+PET+PE, BOPPYOPP+PET+AL+PEBOPPYOPP+PET+ aluminum plated +PE kraft paper + aluminum plated/aluminum +PED, etc

Note:

1. Size: The size and length of the bottom of the eight-sided seal bag should not exceed 38cm, and the bearing capacity of the eight-sided seal in the test should be controlled at 10kg. On the one hand, the bearing capacity of the eight-sided seal is mainly at the bottom of the bag, which is not very good. With the increase of composite strength, the improvement effect is not significant. The main problem is the eight-sided sealing structure.

Number of plate making: When printing eight-sided sealing bags, the front, back and bottom should be printed at the same time, and both sides should be printed separately. Therefore, two sets of intaglio plates need to be made for each package of the eight-sided seal bag (only one set of version is needed if both sides are empty). Therefore, clients are advised to design with as few colors as possible, generally no more than three colors, and design more information on the front and bottom. The number of plate making of the eight edge sealing bag is a set of plates made separately on both sides of the front and back, and a set of plates made separately on both sides. The total number of plates is obtained after being added up.

3. Side printing: Size deviation will inevitably occur in the bag-making process. If it is full plate printing, the printed content may be edged. Therefore, in the design to consider the edge distance, improve the fault tolerance of the packaging bag.
