Lollipop bag

Whether on the shelves of supermarkets or convenience stores, we can see many lollipop packaging bags will be added with sealed zippers, the main purpose of which is to increase the reuse of packaging bags, so that people do not eat food, can be sealed and stored, convenient to eat next time will not affect the taste of food, and increase the product experience of users.

There are actually two kinds of food zippers. One is the 'two-sided zipper.' "The two sides of the seal are heat-sealed with the inside of the package. When in use, just tear off the hot seal. When not in use, simply pull your finger from the seal on the left side of the bag to the right. Even if there is no heat seal packaging in the production process, the double zipper also plays a double seal role, which undoubtedly provides an important guarantee for the quality of our products! Of course, we don't want that to happen.

The other lollipop bag has a single zipper, "with only one side of the seal attached to the heat seal inside the bag. Usually, we choose the back of the package as the bonding part of the zipper. Unlike the double-sided zipper, the external opening needs to be opened during use, which not only ensures the sealing function, but also enhances the overall feel of the bag without damaging it. But if there is no heat seal during the manufacturing process, the single-zipper bag will not be as protective as the double-zipper bag.

Lollipop bag single-side zipper bag is mainly used for 8-side ziploc bag. For example, when some high-end products and enterprises pay more attention to the integrity of the bag, it is recommended to use a single zipper bag, such as eight-sided sealed tea bag, eight-sided sealed candy bag, eight-sided sealed pet food bag, etc. The double-sided zipper is the common sealing zipper we have seen, mainly used for three-sided sealing and stand - up bags.
