One of the edges of the shrink film is for crease forming and the rest three sides are used for sealing purposes. After wrapping of shrink film, the product proceeds to the heating tunnel. It gives tight, fit, and robust packaging of the product which make them durable and eco-friendly.
4. How Shrink Wrap Machine Work?
Shrink wrap machine offers tightly wrapping of plastic film on products. It has a common working principle for both manual and automatic operations but the only difference is in the handling and controlling process. The operational processes of both manual and automatic shrink wrap machine are as follow
a. Manual Shrink Wrap Machine
- External parameters involved in the process including power supply, device maintenance, cleaning, gun heat temperature and pressure checked and set to standard value.
- Manually film reel is stretched onto the surface of the product and is properly wrapped with it. Heat at standard temperature is applied to shrink the film on the product surface.
b. Semi-Automatic Shrink Wrap Machine
Semi-automatic shrink wrap machines follow an intermediate working principle as compared to both manual and fully automatic machines.
- Initially all external parameters including power supply; device maintenance, cleaning, heat and conveyor speed are set to standard.
- The product is fed by the operator onto the moving rollers and sent to the system. Manually wrapping of shrink film is done and then proceeded to the system.
c. Automatic Shrink Wrap Machine
- Like manual shrink wrap machine, all the external parameters including power supply, device maintenance, cleaning, heat, and conveyor speed are set to standard.
- As the parameters are set, the process of product feed takes place. The product is placed on the conveyor belt or rollers and then it enters the film dispensing area.
- Here the film is wrapped on the product automatically. As the wrapping gets completed, the product enters a controller chamber where heat is applied to it and the process of shrinking is carried out.
