When the machine is used continuously for more than three months, the temperature resistant wires in the contraction chamber should be inspected and replaced according to their aging degree. During machine operation, the operator's palm and other parts are not allowed to come into contact with the operating parts of the machine, especially the extremely high temperature inside the contraction chamber, which can easily cause burns. After the packaging work is completed, the heating switch should be turned off first, and the conveyor motor and fan motor should continue to run for about 10 minutes before cutting off the entire power supply.

Machines like packaging machines must be reliably grounded to protect personal safety. Each machine comes with a power cable that is connected to the power supply when it leaves the factory. The end lead of the cable has an identification symbol for the power supply and must be connected correctly. Violating regulations may cause electric shock.

There are two ways to wrap items with flat film: single flat film and double flat film. The film should be wider than the object, using a double flat film, that is, wrapping it with two films on top and bottom. While the previous packaging is completed with sealing and cutting, the two films are sealed together. Then, the product is pushed into an upright film by machine or hand, and the sealing and cutting mechanism falls in place. The other side of the product is sealed and cut off. The product wrapped in the film shrinks after heat shrinkage, and the two ends of the packaging shrink to form an elliptical opening. When using a single flat film, First, unfold the flat film and feed the wrapped product towards the middle of the film to form a horseshoe shaped wrap, then heat seal and overlap the seal.

The products packaged by the shrink packaging machine can be sealed, moisture-proof, and impact resistant, suitable for tightly wrapping multiple items and pallet packaging; The digital display computer is capable of temperature control and has a small temperature difference; Stable and reliable, low noise, and long service life; During the shrinkage process, it does not affect the quality of the packaging, but can shrink quickly. The packaged product can be sealed, moisture-proof, and impact resistant, suitable for tight packaging of multiple items and pallet packaging.
