The four-side sealing structure makes the overall rigidity of the packaging stronger, which can better resist extrusion and collision during transportation and stacking, and protect the internal products. 3. Excellent anti-theft and hygiene protection: The packaging must be destroyed to be opened, providing a strong anti-theft function. 4. High-end appearance to enhance brand image: The four-side sealing makes the packaging appearance flatter, straighter and more exquisite, creating a more high-end and reliable visual experience, which helps the product stand out on the shelf.
