Cast Shrink Wrap
We have our own R&D team. We hold 2 invention patents and 17 utility model patents. One of these patents is for a better shrink film formula. We improved the PE material mix. The result is a cast shrink wrap that shrinks at a temperature about 10°C lower than normal. This makes your heat gun work easier. You are less likely to burn a hole in the film. We also improved shrink uniformity. In the past, some films shrank tighter on one side than the other. Our film does not.

Our R&D Investment Pays Off
We have our own R&D team. We hold 2 invention patents and 17 utility model patents. One of these patents is for a better shrink film formula. We improved the PE material mix. The result is a cast shrink wrap that shrinks at a temperature about 10°C lower than normal. This makes your heat gun work easier. You are less likely to burn a hole in the film. We also improved shrink uniformity. In the past, some films shrank tighter on one side than the other. Our film does not. We tested it. Shrink rate can reach 55% or more. The national standard only asks for 50%. We are higher. These improvements came from our own R&D. We are a certified national high-tech company. That means our technology is recognized. So when you buy our product, you get better performance.
