These bags are typically made of multi-layer composite materials, offering excellent moisture resistance, oxidation prevention, and durability, effectively shielding the contents from external environmental factors.
The appearance of center-sealed bags is simple and neat, with surfaces that can be printed with brand information, patterns, and product descriptions for easy promotion and display. Many center-sealed bags also come with tear notches or resealable closures, making them convenient for consumers to use.
### **Applications of Center-Sealed Bags**
