Mingca Cross-linked Film from China Suppliers - High-Performance Packaging Factory Solutions
Product Description
（1）Standard Cross-linked film
Standard cross-linked film is a polyolefin shrink film that undergoes physical radiation cross-linking treatment. By utilizing advanced cross-linking technology and optimized raw material formulations, it achieves multiple performance breakthroughs.
🚀
Key Features: Excellent tear resistance, long-lasting high-strength sealing properties, and superior shrinkage rates (over 70%). It eliminates the "wire string" phenomenon and ensures a perfect, tight fit on product surfaces.
🌡️
Shrinkage Temperature:
145℃ - 150℃
*Adjust based on packaging machine temperature and transmission speed.
（2）Low-temperature cross-linked film
Low-temperature cross-linked film is a flexible polyolefin shrink film specifically designed for sensitive items. It excels in low-temperature shrinkage while maintaining high transparency, strong sealing strength, and superior toughness.
🛡️
Ideal Applications: Particularly suitable for heat-sensitive products such as chocolates, skincare items, and electronic devices, protecting them from heat damage during the shrink process.
🌡️
Shrinkage Temperature:
135℃ - 140℃
*Adjust based on packaging machine temperature and transmission speed.
Data Sheet
Frequently Asked Questions (FAQ)
What is the main benefit of cross-linked shrink film?
Cross-linked film offers superior tear resistance, stronger sealing strength, and higher shrinkage rates compared to standard POF films, ensuring more secure and attractive packaging.
When should I use low-temperature cross-linked film?
It is best used for heat-sensitive products like chocolates, electronics, or cosmetics that might be damaged by the higher temperatures required for standard shrink films.
Does this film work with semi-automatic machines?
Yes, both standard and low-temperature cross-linked films are compatible with various automatic and semi-automatic packaging equipment.
What is the maximum shrinkage rate of these films?
The standard cross-linked film provides a high shrinkage rate of over 70%, allowing it to conform tightly to the product surface.
Can I use the same temperature for all packaging machines?
While we provide recommended ranges (135℃-150℃), temperatures should always be adjusted based on the specific machine's speed and heat tunnel efficiency.
Does the film leave residue or "wire strings" during sealing?
No, the advanced cross-linking technology effectively avoids the "wire string" phenomenon, ensuring clean and strong seals.
