Packaging bag/yogurt cover laser window opening case

The window opening process of packaging bags is a common product packaging process. Generally, the bottom film of the belly after the window opening of the packaging bag is used to let customers intuitively see the internal situation of the product, increase customer trust, and improve product sales.

Today, Laisai Laser will talk about the surface of the product (as shown in Figure 1). Now many people have the habit of drinking yogurt and milk tea. Generally, yogurt and milk tea are sealed with a laminating machine, which can achieve a good preservation effect. However, there are still some troubles in the actual use of this type of product by users.

First of all, it takes a lot of force to tear the film apart, and the duck mouth is very short, which can easily lead to the duck mouth being torn off. The second situation is that it is not easy to preserve. The laser window opening process of the yogurt cover can solve this problem very well (as shown in Figure 2). The yogurt cover adopts a double-layer laminated film style, with the bottom layer made of transparent materials such as PP, PE, and PET. The opening at the mouth of the cup can be glued back after the surface film is torn off, which greatly improves the difficulty of users in drinking and preservation. It has a good customer experience and is the best choice for casting brands.
