1. What is an eight-side sealed bag?
As the name suggests, the eight-side sealed bag has eight sealed edges! The core lies in the solid "cross seal" at the bottom, forming four stable bottom corners (plus the side and top seals, a total of eight). This design brings:
Super strong load-bearing capacity: The cross bottom seal has strong support, and it is not easy to break the bottom and deform when loading heavy objects (such as pet food).
Three-dimensional and full: After being filled, it is like a small square box, with six sides flat and straight, and the shelf display effect is outstanding.
Composite material: Multi-layer material composite, taking into account both strength and functionality (such as moisture-proof, barrier, and freshness preservation).
2. Five advantages of choosing eight-side sealed bags:
Strong load-bearing capacity: The cross bottom seal is specially designed for heavy products (pet food, cat litter, rice, flour, etc.), and bid farewell to the trouble of broken bags.
Eye-catching weapon: The three-dimensional square shape provides six perfect display surfaces, significantly enhancing the brand image (the first choice for high-end pet food, boutique coffee, and nut gift boxes).
Self-standing and space-saving: Full bags are stable and self-standing, and empty bags are flat and easy to store and transport, saving space and cost.
Upgraded protection: Customized material combination to achieve moisture-proof, leak-proof, lock freshness, and extend the shelf life of products.
Convenient opening and closing: The top can be heat-sealed (economical) or zippered (easy to open and close), and the large opening design is convenient for pouring.
3. Core Difficulties and Our Professional Solutions (Bottom Cross Seal is the Key!)
The success or failure of the eight-side sealed bag lies in the bottom cross seal:
Difficulty 1: Precision and firmness: The four corners must be aligned with high requirements, and the cross intersection must withstand the maximum pressure. Improper process is prone to cracking and leakage.
Difficulty 2: Three-dimensional fullness: Materials and processes must be coordinated to ensure that the bag is sharp and crisp after being filled.
Difficulty 3: Full sealing: The eight sealed edges (especially the complex bottom) must be tight to prevent leakage.
