What are the temperature requirements for POF shrink film?
The shrinkage temperature of the POF shrink film is generally 150 degrees. The setting of the temperature difference depends on the shrinking furnace itself. A good shrinking furnace can shrink at about 120 degrees. The old-fashioned heating tube shrinking furnace can even be set to 200 degrees to shrink. There is a process for the product to enter the heat shrinking. Generally, it is heated first, then expanded and finally shrunk.
Shrinking films of different materials can be used to select different functions of the shrinking furnace. When shrinking, the shrinking film should be vented according to the different conditions of the product, so that the internal gas can be run away during shrinkage. It will not swell up due to the internal gas after the shrinkage is completed, which will affect the appearance. POF environmentally friendly heat shrinkable film is best to choose the constant temperature shrinking furnace in the furnace temperature cycle, which can avoid the uneven heating of the product during the shrinking process and affect the shrinkage effect.
With the rapid development of China's economy and society, China's POF shrink film industry will enter a stage of rapid development with a higher than global average growth level. The main reasons are as follows:
1 The application field of POF heat shrinkable film in China is at a high speed development stage;
2 The application range of POF heat shrinkage in China has been continuously expanded with market development and consumption practice;
3 POF heat shrinkable film has become the mainstream display packaging material for light and small products;
4 Packaging mechanization Drives the demand for high quality POF shrink film.
