The production process of PVC zipper bag:

1. Set up the pattern and make a zipper copper mold.

2. Cut the material, calculate the size, and cut the material into the style of a zipper bag. If silk screen printing is required here, set the material and silk screen in a good position.

3. String zippers. The zippers bought back are one plus a zipper puller. Here you need two layers, and then string the zipper pullers.

4. Press into a finished product. This step is to press the zipper and PVC material into a plastic bag. In this step, it is necessary to control the pressure of the electric machine and the distance of the trimming. The edge of the zipper bag should be free of burrs and smooth. smooth.

PVC zipper bag is actually a kind of plastic bag. The main ingredient is polyvinyl chloride, which is bright in color, corrosion-resistant, and durable. Because some chemical additives such as plasticizers are added in the manufacturing process to enhance its heat resistance and toughness. , ductility, etc., so its products generally do not store food and medicine. It is a well-loved, popular and widely used synthetic material in the world today.

Production method and precautions of PVC zipper bag:

PVC zipper bag is also a kind of plastic bag. It has two materials of low toxicity and environmental protection. It is made of PVC film. Zipper bags are generally divided into two types, flat pockets and three-dimensional bags. Today we mainly introduce how to make flat pockets.

PVC zipper bags need to prepare copper molds, zippers, PVC roll film, and use high-frequency voltage PVC zipper bags:

First of all, you need to cut the material, first cut the PVC roll film into pieces, and print the silk screen first, and align the position when printing, otherwise the printing may be skewed when the voltage is applied!

Then there is the need for voltage. Put the zipper on, turn it on the copper mold, adjust the mold, and the temperature should be appropriate, and then you can voltage it into a finished product. The production speed of flat bags is generally very fast, and now there are automatic high-frequency voltage machines. faster.
