1. Unitization. The product is compact and firmly bundled into a unit, making the scattered small parts a whole and avoiding damage.
2. Primary protection. A very light and thin protective appearance is formed around the product to achieve the purpose of dust-proof, oil-proof, moisture-proof, water-proof and anti-theft. Avoid damage to items caused by uneven force.
3. Pressurize and fix. Wrap and package the product to form a compact unit that does not take up space, so that the trays of the product are tightly wrapped together, which can effectively prevent product misalignment and movement. The adjustable pulling force can make hard products tight and soft products tight, especially Especially in the tobacco industry and textile industry, it has a unique packaging effect.
4. Cost saving. Using POF shrink film for product packaging can effectively reduce the cost of use. The usage of POF shrink film is only about 15% of the original box packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grades.
Many customers who use POF shrink film find that the packaging effect of POF shrink film is poor, that is, when the shrink effect is not good, it is generally believed that there is a problem with the quality of POF shrink film. This is a misunderstanding.
The effect of shrinkage temperature on POF shrink film. The shrinkage effect is linked to the actual shrinkage temperature. Excessively high temperature will easily lead to shrinkage and cracking of the plastic film; when the temperature is low, the shrinkage effect of the POF shrinkage film will be uneven. Therefore, manufacturers need to adjust the temperature several times when producing POF shrink film to find the most suitable temperature value
