VMPET Twist film
1. High bond strength between Aluminum layer and base film, good brightness.
2. Nontoxic, odorless, moisture proof, save fragrance
3. Good twist, and small rebound angle
4. joint rally strong, high strength
5. Mainly used in candy, beef jerky and other small food packaging
6.Normal specification:20μm,Thickness of Aluminum layer is 380A,length: 4000m、6000m、8000m/roll,3″paper core, other specifications are customized.
