Tension‑Free Flat Bag Machine is a high‑performance plastic film converting equipment specially built for manufacturing various flat plastic pouches. Adopting non‑stretch structure design, it effectively avoids film elongation caused by pulling force during production, delivering finished bags with stable dimension and uniform wall thickness.
Core Advantages of Tension‑Free Flat Bag Machine
1. Tension‑free feeding system: The core highlight of Tension‑Free Flat Bag Machine. Flying‑knife cold cutting technology cuts material without stretching the film, especially suitable for thin‑gauge PE film processing, no bag deformation or uneven thickness.
2. High‑precision servo control: Servo motors govern film feeding and cutting length, with cutting accuracy up to ±0.5mm. Photoelectric eye supports register tracking for pre‑printed films.
3. Stable heat‑sealing performance: Constant‑temperature sealing knives offer firm, smooth sealing edges. PLC touch‑screen panel simplifies parameter setup for bag length, speed and temperature.
Application Scope
Produce flat garment bags, vacuum food pouches, hardware packaging bags, gift plastic bags and disposable packaging bags. Suitable for plastic product factories, packaging manufacturers and converting enterprises.
