In industries where reliable packaging is essential, choosing the right bags is just as important as product quality, and Formosa’s Block Bottom Bags offer a dependable solution. Also known as AD*STAR bags, they are a cost-effective alternative to paper bags, designed in a brick-like shape for better stability during storage and transport. Widely used across sectors such as cement, chemicals, food grains, and fertilizers, these bags combine strength with efficiency. Formosa ensures high-quality production with features like a valve for easy filling, a hermetically sealed structure that prevents tampering, excellent moisture resistance, tear-proof durability, and high load-bearing capacity, making them suitable for demanding applications.

The manufacturing process of PLWPP Block Bottom Bags involves loading a tubular roll of coated or laminated printed woven polypropylene fabric onto a machine, where it is cut to the required length. The ends are then folded and sealed using heat and pressure to create an airtight closure. A patching process adds a rectangular strip of matching material, during which the valve is formed. Typically, these bags are made using coated or laminated woven fabric, ensuring durability, protection, and consistent performance.
