Custom Middle sealing bag
Optimize your high-speed production with our custom middle sealing bags (center seal bags). Designed for exceptional back-seal strength and rapid automated filling, these bags are the most cost-effective solution for snacks, candies, and dry goods. We deliver food-grade laminated materials, vivid custom printing, and accommodating MOQs to support growing global brands efficiently.
Our custom middle sealing bags (also known as fin seal or back seal bags) feature a robust continuous seal down the back, offering a traditional, highly efficient packaging format. This structure is engineered for maximum speed on Vertical Form Fill Seal (VFFS) packing lines, making it the go-to choice for high-volume snack and confectionery brands worldwide.

-
Burst-Resistant Back Seal: The reinforced center seal provides superior structural strength to withstand nitrogen flushing and prevent bag bursting during heavy transit and handling.
-
Optimal Barrier Protection: Constructed from multi-layer, food-safe laminations that strictly block oxygen, moisture, and light, keeping your gummies and snacks perfectly fresh.
-
Custom Retail Features: Fully customizable with functional add-ons like Euro-holes for pegboard displays, easy-tear notches, and transparent product windows.
-
