How to Avoid Wrinkling of Frosted Zipper Bag?

Zipper bag is a very good thing in the category of soft plastic packaging. It has the advantages of convenience, speed, and special-use. Among packaging manufacturers, the requirements for the production process are still high compared with plastic bags without zippers.

Today, we’ll talk about how to avoid wrinkles in frosted zipper bags and precautions for use of frosted zipper bags.

How to avoid wrinkles in frosted zipper bags?

There are two common problems with frosted zipper bags: one is the partial layers or surface folds on both sides of the zipper; The other is the surface folds of zippers and bags.

The folds on both sides of the frosted zipper bag are sometimes closely related to the choice of the zipper. When purchasing zippers, it should be noted that the dissolution point and shrinkage rate are lower than or equal to the dissolution point and shrinkage rate of the heat permeable layer of the composite bag, to prevent a serious mismatch between the dissolution point and shrinkage rate.

In the whole process of making a frosted zipper bag, water cooling specification is one of the key factors. If the deformed frosted zipper bag can obtain sufficient water cooling before the production and processing of the packaging bag, the probability of thermal shrinkage of the composite bag produced and processed by the packaging bag will be greatly reduced under the storage specification.

If the heat permeable layer and zipper in the frosted zipper bag are still in the melting or viscoelastic state, under the storage specification, the heat permeable layer and zipper will certainly lead to shrinkage film in a sense and relatively horizontal surface wrinkles.

Precautions for use of frosted zipper bags

1. Be sure to pay attention to the frosted zipper bag before and after pumping, so as not to be scratched by sharp objects. In practice, the stream is on the bed or a clean desktop. If there are hard blocks such as buttons and zippers, please put them in the storage bag. When stored in a wooden cabinet or other location, pay attention to whether there are objects in the storage address to ensure that the packaging bag is intact.

2. Clothes, trousers, mattresses, and other items should be put into the frosted zipper bag as far as possible, at least 3-5cm away from the sealed zipper, without forced amplification.

3. Make sure the zipper part of the frosted zipper bag is clean. If there is chemical fiber and dust, the sealing performance will be reduced. It is recommended to scrub with water touching an abrasive cloth and then close the zipper. When the zipper is closed, hold the rotor tightly and pull the sealing ring back and forth several times to ensure that the two ribs of the sealing are fastened and the sealing effect is ensured.

4. When using the pump, rotate the screw joint of the pump to the lower end, and use a milky vulcanized rubber pad to resist the vacuum port to ensure that the joint will not leak. Usually, a small bag needs to be smoked for 3 minutes and about 3.500 times to be flat. When using the air extraction pump, pay attention to continuous air extraction. It is suitable to have a vacuum cleaner at home, which is easy and convenient.

5. After pumping, please check the seal again to ensure the seal.
