Introduce the use process of zipper bag.stand up coffee bag with zipper

　　Plastic packaging bags have a variety of forms and functions, and zipper bags are one of them, which are widely used.

　　Before and after inflation, the zipper bag should be careful not to be scratched by sharp objects. The operation should be carried out on the bed or on a clean table as far as possible. If there are hard objects such as buttons and zippers in the stored items, please fold them inside and put them into the collection bag. When storing in a cabinet or other place, pay attention to whether there are sharp objects in the storage place to ensure the integrity of the bag.

　　Clothes, quilts and other items should be placed inside the colorful zipper bag as far as possible, at least 3-5 cm away from the closure zipper, and large items should not be put forcibly.

　　To ensure the cleanness of the zipper part of the zipper bag seal, if there is fiber and dust entering, the sealing performance will be reduced. Wipe the zipper with wet gauze and then close the zipper. After closing the zipper, please hold the slider tightly and pull it back and forth several times at the seal to ensure that the two ribs of the seal are fully buckled into the groove to ensure the sealing effect.

　　When using the air extraction pump, screw the screw connection of the pump to the bottom, and hold the white rubber sealing gasket of the air extraction port to ensure that there is no air leakage at the connection. The manufacturer of Henan Trilateral Zipper Bag pointed out that a large bag needs to be pumped for 3-5 minutes. When using the air extraction pump, pay attention to continuous pumping and try not to stop.

　　After pumping, please check the seal again to ensure that it is sealed.
