The transparency of PE protective film is crucial to the product's quality, and here, Kaimei, the protective film manufacturer, introduces how to enhance the transparency of PE protective film:
1. PE protective film is a crystalline material that crystallizes easily. Without rapid cooling, it is inevitable that the transparency and elongation at break will decrease. Blow molding processes have poor cooling effects, high crystallinity, and low film transparency.
2. Due to blowing and stretching, the molecular orientation is severe, resulting in low elongation at break; however, the cooling effect in cast film production is excellent, with low crystallinity, good transparency, low orientation, and thus high elongation at break and good shrinkage properties.
3. Add an appropriate amount of anti-fog agent.
4. On top of that, incorporate a transparent nucleating agent.
5. We select PE protective film raw materials with low hazing and high melt flow index.
