Features & Parameters

This machine heats plastic woven tubular fabric, which is lined with a double-layer co-extruded inner film, to the appropriate temperature using a core mold, then stretches and presses it to ensure the inner film adheres tightly to the woven tubular fabric; The resulting inner-film-laminated composite bags feature an aesthetically pleasing, smooth appearance, excellent moisture resistance, anti-slip properties, and ease of stacking. 

This machine represents the latest generation of equipment for manufacturing packaging bags such as fertilizer bags, chemical bags, sugar bags, feed bags, and cement bags.

This machine utilizes a PLC for centralized control, offering intelligent features such as programmable logic controller (PLC) centralized control, touchscreen operation, automatic temperature and speed control, and fault alarms. It allows for manual adjustment or presetting of temperature and speed, as well as automatic synchronization of bonding operations. The winding system employs a pneumatic torque friction winding mechanism, ensuring the fabric is wound smoothly and securely.
