Zipper bag structure

The invention provides a zipper bag structure, in particular to an environmentally-friendly and reusable zipper bag structure.

With the development of technology, zipper bags have been widely used in a variety of food packaging or storage bags. In the market, the common zipper bag is usually designed with a tear hole on the upper side of the packaged zipper strip. The user can apply the force to the tear hole, and the side of the zipper bag can be removed by inertia. The edge of the bag is such that the upper side of the zipper strip is correspondingly formed with an opening, thereby allowing the user to obtain food or articles in the zipper bag. The above products are quite convenient to use, but the design can only be applied to the upper open type zipper bag, and the upper open type zipper bag has two accommodating spaces on the inner side thereof. The thin wall of the side defines that the amount of food (items) that can be loaded is very limited.

In order to solve the above problems, a side-open type zipper bag is disclosed in the prior art. Referring to FIG. 1A and FIG. 1B together, a side-opening zipper bag 100 is disclosed.
