This liquid packaging bag is built for filling high-viscosity products such as tile adhesive and waterproof coating. The pouch can be made in stand-up or pillow form, with three-side or four-side sealing chosen to match your filling method. The carry handle is formed together with the bag body, and load-bearing areas get a wider heat-seal to reduce tearing during handling. A spout or valve can be fitted at the top for controlled pouring, and the sealed mouth keeps the contents contained when bags are stacked.
Bags are typically laminated from PET, nylon, foil and PE, with the film structure matched to the acidity, viscosity and shelf-life needs of the product, balancing stiffness, puncture resistance and barrier performance. Printing uses 1-8 colour gravure printing, so artwork, colour codes and logo placement follow your supplied files. Standard capacities run from 100ml to 5L, while bag dimensions, handle position and spout diameter can be developed from your sample or drawing. For 4kg filling, thicker films and reinforced seals can be used.
These bags serve coating, adhesive, building material and household liquid lines for both filling and retail packaging. The process is straightforward: send a sample or drawing with capacity and product details, confirm the bag structure, approve the proof, then production starts. Our factory sits in Dongguan, Guangdong, with a Class 10000 clean workshop covering film blowing, lamination, printing and bag making under one roof. MOQ is 10,000 pcs, matching roll film in the same material is available, and shipments follow the agreed schedule.
