The woven bag heat sealing and stitching machine is designed for woven bags (including laminated woven bags) and supports heat sealing of the inner PE liner while applying a crepe-paper tape to the outer surface. It can also be used for other packaging materials with similar structures. The system is commonly applied in chemical, food, and building materials industries where reliable sealing and stitching performance is required.
The woven bag heat sealing and stitching machine is designed for PE-lined woven bags and similar packaging materials. It uses a two-stage sealing process: the inner liner is heat-sealed first, followed by the application of a hot-melt adhesive tape on the outer layer. This structure improves leak prevention, especially for powder products, and enhances resistance to dust, moisture, and handling during transport.
Bag mouth cleaning (optional) → Bag-top trimming (cutting) → Inner liner heat sealing (4 heated-bar assemblies; Teflon sealing belt prevents direct contact between the heated bar and the bag surface, ensuring clean sealing and avoiding adhesion) → Pressure rollers for sealing → Sewing of the outer woven layer → Application of hot-melt adhesive tape → Heat sealing (2 heated-bar assemblies) → Final pressure-roller consolidation

This heated-bar sealing and folding system carries out inner-bag heat sealing followed by bag-top inward or outward folding before stitching. The combined process helps prevent material leakage and provides strong resistance to dust and moisture, making it suitable for demanding industrial packaging environments.
