The model is FQL-450SP Automatic L Type Sealing & Shrink Wrapping Machine. It automatically seals products with an L-bar sealer and then shrinks the film in a tunnel for high-efficiency, mass-production packaging.
Sealer: 220V 1/3ph 50/60Hz, 1.8 kW. Packing size limits: (L+H)<550 mm, (W+H)<400 mm, H<130 mm. Sealing size: 550×450 mm. Packaging speed: 15–30 pcs/min (depends on product size).
Tunnel model BS4522N: 380V 3ph 50/60Hz, 12 kW. Tunnel size 1500×450×220 mm. Conveyor speed 1–15 m/min, conveyor load 30 kg. Overall tunnel dims: 1910×700×1320 mm.
Suitable for POF (preferred fold film), PVC, PP and PET heat-shrinkable films. Max film width ≤ 530 mm, max film diameter (D) ≤ 250 mm, max roll weight ≤ 35 kg.
Sealing blade temperature is controlled by a digital temperature controller with built-in PID for precise, responsive temperature control. The sealing knife uses special steel with Daikin Teflon coating to prevent sticking and high-temperature damage.
Yes. The machine supports unmanned operation and can be connected to a production line. It uses Panasonic PLC control and a WEINVIEW 7-inch HMI for easy integration and operation.
Features include automatic sealing blade protection to prevent accidental cutting, built-in film break alarm, and automatic scrap-recycling mechanism. Photoelectric sensors provide accurate positioning and fast response. Please confirm local safety requirements and optional safety guards with the supplier.
The machine has a manual adjustment film-guide system and an adjustable feeding conveyor platform. The movable-type punching device lets you change punching position and pinhole count. Automatic and manual modes can be switched for film changes.
Regularly clean the Teflon-coated sealing knife, check and tighten mechanical fasteners, inspect the silicone-covered chain bars for wear, verify heater tubes and fans in the tunnel, clean photoelectric sensors, and keep the control panel free of dust. Follow supplier-recommended schedules for lubrication and spare-part replacement.
Common issues: 1) Poor or uneven shrink — adjust tunnel temperature, conveyor speed, or check tunnel fans/heating tubes. 2) Weak or incomplete seals — check PID temperature settings, sealing pressure, knife condition, and film type. 3) Film jams or misfeeds — inspect film guide, photoelectric sensor alignment, and feeding conveyor. If problems persist, contact technical support.
Sealer overall dimension: 1800×800×1480 mm. Package size for transport: 1850×900×1630 mm. Gross/Net weight: 380/350 kg. Shrink tunnel overall: 1910×700×1320 mm; package size: 1960×800×1470 mm; gross/net weight: 290/250 kg.
Power: Sealer 220V (1/3ph) 50/60Hz; Tunnel 380V 3ph 50/60Hz. Air source: compressed air at approx. 6 kg/cm². Provide suitable floor space, proper grounding/earthing, and stable power supply. Verify local electrical and safety codes before installation.
Common consumables/spares include sealing knives (Teflon-coated), heating tubes, silicone-coated chain bar covers, sensors, and electrical components. Contact the supplier for recommended spare kits and lead times.
Warranty and training terms are not specified in the product description—contact the supplier or vendor to confirm warranty length, scope, onsite commissioning, and operator training options.
Designed for high-volume applications across food, cosmetics, pharmaceuticals, hardware, printing, beverages, flooring, ceramics and general consumer goods where shrink-wrapped presentation and protection are required.
