Our PP Woven Pinch Bottom Bags are precision-engineered using the exclusive Starlinger PP STARKON bag-converting machine – the industry benchmark for producing ultra-reliable, leak-resistant closures. This patented technology transforms standard woven packaging into a superior sealing solution for demanding applications. The Pinch bottom bah production process does not merely sew or stitch—it thermally bonds and compresses the bag end with integrated sealing tapes. This creates a multi-layer, fused seal that is inherently dust-tight and sift-proof, far surpassing the integrity of conventional sewn closures.The closure is flat, compact, and free of loose threads, providing a professional finish that enhances brand image. The smooth end facilitates safer, easier palletizing and stable stackability.
Our PP woven pinch bottom bags are manufactured through a fully integrated, automated Starlinger production process that begins with polypropylene granule extrusion and precision tape formation, continues with circular weaving and extrusion lamination for enhanced strength and printability, and culminates in the exclusive PP STAR KON converting technology. This patented thermal compression sealing system fuses the bag ends with special sealing tapes under controlled heat and pressure, creating a molecular-level bond that results in a flat, sift-proof, and exceptionally strong seal—superior to traditional sewing. The continuous "granule-to-bag" line ensures consistent high quality, excellent barrier properties, and reliable performance for demanding applications such as powders, chemicals, and construction materials.
