Therefore, using polyolefin shrink film on your packaging line can save you time while uniformly packaging your products, which can greatly improve efficiency.

Durability: Polyolefin shrink film is a flexible and strong material that can handle picky foods such as cookies and other items with rough edges. Whether you're packaging frozen pizza, pies, or bread, you can be sure that the products contained within are well protected. This helps establish your brand as reliable and consistent.

How to choose the right POF heat shrink film to purchase?

How to test the good and bad POF shrink film, set the test temperature, end temperature, and other test parameters, click on the start test option, and the test begins. When the temperature inside the equipment heating chamber reaches the test temperature, the specimen automatically enters the chamber, the test starts timing, and the specimen is heated to shrink and generate heat shrinkage force, when the heat shrinkage force reaches the set condition, the specimen automatically leaves the chamber, the force value generated thereafter is the cold shrinkage force. The equipment automatically records and displays the heat shrinkage force, cold shrinkage force, and shrinkage rate from the specimen into the chamber to the end of the test in real-time. After the test, the equipment displays the maximum shrinkage rate, maximum heat shrinkage force, and maximum cold shrinkage force for each group of specimens.

High-quality products have high transparency and gloss, good sealing, and good tightness of retraction will not be scattered or incomplete packaging, in addition to protection the product to play the role of not easy puncture. Therefore, we should learn more about shrink film before buying it, master the relevant judgment methods, and choose a good and responsible manufacturer that is regular and critical, the quality of the product will be guaranteed, and its after-sales service quality will also be very good.
