1、 Changes in the amount of content
After changing the ordinary packaging bag into a special-shaped bag, its capacity will certainly change. Therefore, the size of the packaging bag needs to be redesigned.
2、 Changes in the shape and edge of packaging bags
Because it is a soft packaging bag, the outer edge of the packaging bag should not be used with sharp corners, so as to avoid puncturing other packages or injuring users.
3、 The influence of packaging method
If the special-shaped bag is sealed by automatic sealing equipment, in order to facilitate the smooth production, there are certain requirements for the opening direction and sealing position of the special-shaped bag, which also needs to be considered
In the comprehensive consideration of the above factors, combined with the exquisite pattern design, a successful special-shaped flexible packaging bag was born.
According to the different forms, the special-shaped bags can be divided into the following several types.
1 Special bag Suction nozzle bag
The function of the nozzle is to facilitate the dumping of the contents, and the product after the nozzle can be re sealed, which means that it can be unsealed for many times. This special-shaped aluminum foil bag is suitable for liquid drinks, shower gel, shampoo, tomato sauce, edible oil and other liquids, or other liquid products that need to be unsealed for many times.
2 belt Zipper shaped bag
The function of adding zipper is also to facilitate the use of multiple unsealing. But the difference is that the way of repeated sealing is zipper, so this kind of design is not suitable for packaging liquid, but for some light dry items, such as candy, dried fruit, chocolate, biscuit, jelly, tea, etc.
3 Mouth shaped bag
The characteristic of this kind of packing bag is that there is no additional mouth in the packaging design, but a bag shape similar to the mouth is made by using the production characteristics of the special-shaped bag, which is convenient to use. This design is suitable for liquid refilling, because once it is opened, it can't be sealed again. The applicable products are basically the same as those of the special-shaped self-supporting bags with nozzles.
