Film Blowing Machine Manufacturer
The 450X2 double layer carry bag machine automates the entire production process from film unwinding to counting and stacking, enabling high-speed dual-line manufacturing of vest bags with precision registration and heat sealing.
| Bag Thickness(mm): | 0.005~0.05 |
| Bag Making Width(mm): | 200-400/200-450 |
| Bag Making Length(mm): | 300-720/300-800 |
1. Unwinding and flattening: The plastic film rolls are mounted on the unwinding rack, and through the tension control system and leveling rollers, the film is ensured to feed into the machine smoothly and evenly.
2. Folding and center sealing: After the film is sealed by the sealing blade, perforated disposable bags are formed. Then they are folded through the folding rack and automatically loaded into packaging bags. They can be packaged one by one.
3. Vest mouth mold positioning and heat sealing: The machine uses photoelectric sensors to track the registration marks on the film to ensure the correct position for each bag. The bottom of the bag is heat sealed using a heat-sealing blade, simultaneously forming the shoulder shape characteristic of vest bags.
4. Counting and stacking: The finished bags are conveyed out via a conveyor belt and counted by a counter, and finally neatly pushed into packaging bags for packing and sealing.

The AB double-layer co-extrusion system utilizes two extruders to separately process virgin PE surface material and recycled core material, combining them in a precision die to produce high-quality, cost-effective composite film.
The main part of the bag-making machine uses three sets of servo motors. It can be applied to LDPE, HDPE, PBAT, and biodegradable materials.
The 450X2 double layers carry bag making machine achieves high-speed production of up to 300 bags per minute per lane with three servo motors, supporting both LDPE and HDPE materials for efficient and sustainable packaging solutions.
