How is shrink wrapping done? The process is very simple. Before understanding this process, we must first understand what is shrink wrapping.

What is shrink wrap?

Shrink wrapping is one of the more advanced packaging methods in the market. The shrink film is used to wrap the product. After heating, the film wraps the product tightly, fully showing the appearance of the product, improving the product's displayability, and increasing the beauty and sense of value. At the same time, the wrapped product can be moisture-proof, anti-pollution, and protect the goods from external shocks, and have a certain cushioning property. Especially when packaging fragile items, it can prevent the glass from being scattered when broken. In addition, the possibility of the product being dismantled and stolen can be reduced.

How is shrink wrapping done?

The heat shrink wrapping process is mainly completed by a professional shrink wrapping machine. The main workflow is as follows:
1. close the power switch, the power is on
2. turn on the conveyor belt and fan switch, and then turn on the heating switch
3. set temperature(According to the product size and film thickness, adjust the upper and lower chamber temperature adjustment knobs and conveying speed)
4. after debugging to meet the requirements of use, shrink wrapping can be carried out.
5. after the operation is over, first turn off the heating switch, let the conveying motor and hot air motor continue to run for about 10 minutes, and then cut off the power supply.
In practice, if there are too many wrinkles after shrinking, the conveying speed can be reduced or the heating temperature can be increased. On the contrary, if excessive shrinkage occurs, the temperature can be lowered or the conveying speed can be increased.


1. Nice appearance, suitable for all kinds of different shapes of commodity packaging.
2. Good protection, if the inner packaging of the shrink wrap is combined with the transport packaging hanging on the outer packaging, it can have better protection.
3. Good economy.
4. Good anti-theft. multiple products can be packed together to avoid loss.
5. Good stability, the product will not sway in the packaging film.
6. Good transparency. customers can directly see the built-in products.
