The IEC value of the cross-linked membrane is slightly reduced; the water absorption and swelling are well controlled and have good dimensional stability; the hydrophilic and hydrophobic phases are obviously separated on the membrane surface, and the aggregation size and continuity of the hydrophilic micro-zone change with the length of cross-linking time; the conductivity value decreases slightly with the extension of cross-linking time, but the room temperature conductivity of the membrane is still higher than 0.01 S/cm after cross-linking.
The cross-linked film is a good substitute for PE film, which has a wide space and is in line with the company's future direction of positioning high-end films. Previously, the market expected that the expansion of the product is difficult, we believe that based on the role of packaging machinery, cost-effective and demonstration effect of the three factors, the development of downstream will be accelerated.
POF shrink film main features.
1. Clear and transparent packaging appearance, bright and attractive.
2. High shrinkage rate, ideal for combination packaging.
3. High shrinkage rate, packaging can be kept smooth and bright, without wrinkles and corners very tightly.
4. The finished product rate per roll is increased and the capacity of the production line is enhanced.
