• L-type Sealing & Cutting Integration: One machine completes sealing, cutting, and shrinking, saving production space and improving efficiency.
• Close Contact Function: Perfect for small products (H≤150mm) like pre-made dishes and instant noodles-no loose packaging.
• Multi-model Optional: Match HF-450M with HT-500G (high-speed) or HT-400 (compact) based on your production needs.
• No Mold Replacement: Adjust film guide and conveyor height to fit different product sizes, reducing downtime.
• Automatic Waste Recycling: Built-in waste induction motor rolls up waste edges automatically, reducing manual work.

 

 

 

Industry Applications Widely used in food, daily chemical, and pre-made dish industries for small product packaging needs.

 

 

 

• Food industry: Pre-made dishes, self-heating hot pot, bucket instant noodles, small snack boxes
• Daily chemical industry: Disposable cutlery sets, small shampoo bottles, toothpaste boxes, mosquito coils
• Hardware industry: Small tool boxes, electronic components packaging

 

 

 

1. This machine is a fully automated L-shaped sealing, cutting, and shrinking packaging equipment that can be connected to various fully automated packaging assembly line operations.

2. Built in Omron PLC programmable controller, with safety protection and fault alarm functions, improves the stability of the machine operation.

3. The sealing and cutting knife adopts DuPont Teflon anti sticking coating from the United States, which will not crack or scorch the seal; The sealing and cutting knife has an automatic protection function to prevent accidental cutting of packaging materials.

4. Adjust the height of the film guiding device and the feeding and conveying platform to package products of different widths and heights without changing molds and bag makers.

5. Automatic feeding, bag making length is automatically controlled by a combination of electric eyes and timers; Equipped with a waste induction motor, it can automatically roll up waste edges.

6. Equipped with an independent and freely movable injection hole deflation device to make the packaging more aesthetically pleasing.

7. Equipped with Japanese Panasonic brand detection photoelectric, one set for horizontal and vertical detection, switch and select to package thinner and smaller items.

8. Adopting Taisong digital temperature controller, the temperature can be set freely, and the sealing and cutting temperature is extremely sensitive and accurate.

The HT-500G has a close contact function between the feeding and discharging conveyor belts, which can package smaller items and expand the packaging range.
