Both of PETG shrink film and POF shrink film are commonly applied in flexible packaging industry. What are the differences between them two?
PETG shrink film
PETG shrink film has the following advantages.
high strength
high heat shrinkage rate
 packaging effect is beautiful
 The biggest advantage of PETG polyester film is its good heat sealing performance.
The optical properties and mechanical extensibility are good

PETG has passed the US FDA’s food contact standards. It can be used in food and personal health care product packaging like medical and health equipment food and other fields. Meanwhile. It can also be used in electronic device packaging. It meets International EU ROHS, REACH certification and US food FDA certification, and  environmental protection recycling requirements.
POF shrink film application
POF is mainly used for packaging regular and irregular shaped products, such as automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, photo frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned beverages, dairy products, medicine, cassettes and video tapes.
The shrinkage rate of POF shrink film is up to 75%, and the flexibility is good. It can be used to package products of any shape, and the shrinkage force of the three-layer co-extruded film after special processing is controllable, which can meet the shrinkage requirements of different commodity packaging.
