Engineered Overview & Technical Deep-Dive — Narrow Heat-Seal Bag Machine — 350 / 450
Technical Architecture & Mechanical Design
The Narrow Heat-Seal Bag Machine — 350 / 450 (Heat-seal · narrow) is a high-speed, fully automated plastic bag converting system designed by Wenzhou Ashal Innomech Technology for multi-lane heat-sealing, cutting, and stacking applications. Driven by high-precision Panasonic/Yaskawa AC servo motor control systems, the machine achieves a converting speed rating of 30–150 pcs/min while maintaining cut length accuracy within ±0.5 mm. The unwinding section features an automatic photoelectric web guiding system (EPC) with magnetic powder tension control, ensuring smooth film feeding without lateral wander or material stretching. The sealing assembly incorporates heavy-duty copper sealing knives heated by ceramic heating elements and monitored by micro-processor PID temperature modules to achieve flawless, high-strength heat seals on both light-gauge and heavy-duty films. The flying cutter blade is forged from high-carbon tungsten alloy steel, delivering ultra-clean cuts across millions of continuous operating cycles. An integrated PLC interface with touchscreen HMI allows operators to set bag length, batch count, punch timing, and speed parameters instantly, reducing job setup times to under 3 minutes.
Industrial Applications & Resin Processing
Capable of converting films made from LDPE, LLDPE, HDPE, Recycled PE, bio-degradable PLA/PBAT materials, and recycled plastic films, the Narrow Heat-Seal Bag Machine — 350 / 450 produces T-shirt shopping bags, flat produce bags, bottom-seal heavy garbage sacks, vest bags, vegetable bags, and roll bags. It handles web widths up to 50–350mm with multi-lane configurations for doubled or tripled production output.

Key Engineering Innovations & Quality Assurance
Servo-Driven Flying Cutting & Sealing Mechanism
Independent AC servo motors drive feed rollers and cutter movement, enabling precise synchronization, zero vibration, and instant length adjustment without gear changes.
Auto Hydraulic Punch & Stacking Table
Integrated hydraulic punch unit automatically stamps out T-shirt handles or die-cut handles with automatic waste scrap extraction.
Static Eliminator & Photoelectric Eye Tracking
High-voltage ion static bars eliminate static charge for smooth bag stacking; German-made Sick photocell tracks printed registration marks for printed bag cutting.
Automatic Alarm & Zero-Defect Auto-Stop
Intelligent sensors detect film jam, loss of print mark, temperature drop, or bag stack completion, stopping the machine automatically to prevent material waste.
⚡ Installation & Utility Requirements
Requires 3-phase 380V/415V electrical power supply with total installed capacity of 12KW. Pneumatic air pressure must be maintained at 0.6–0.7 MPa with an air consumption rate of 0.4–0.8 m³/min for punch cylinders and bag collection arms. Floor placement requires a smooth level floor pad with minimum 1.5 meters perimeter clearance for raw film roll loading and finished bag palletizing.
🛠️ Preventative Maintenance Protocol
Daily maintenance requires clearing plastic scrap from the punch die area, wiping sealing knives with silicone oil spray, and inspecting blade sharpness. Weekly checks include lubricating linear guide rails and drive chains with ISO VG 68 grease. Monthly routine includes checking pneumatic cylinder seals, checking electrical terminal tightness, and inspecting EPC sensor optics.
