Frequently Asked Questions
Q1 What is Cross Link POF shrink film and how does it differ from regular POF film?
Cross Link POF (Polyolefin) shrink film undergoes a cross-linking process that significantly enhances its molecular structure, resulting in superior tensile strength, tear resistance, and more uniform shrinkage compared to standard POF film. This makes it ideal for demanding packaging applications in cosmetics and electronics industries.
Q2 What gauge (thickness) options are available for this shrink film?
This Cross Link POF shrink film is available in five standard gauges: 12um, 15um, 19um, 25um, and 30um. Each thickness offers different mechanical and optical performance values to suit various packaging requirements and product weights.
Q3 At what temperatures does the film achieve its best shrinkage performance?
The film delivers excellent shrinkage results across a range of temperatures. At 120°C, free shrinkage reaches up to 70.5% (TD) and 72% (MD), while at 130°C it achieves up to 81% in both directions. These properties make it highly adaptable to different automatic shrink packaging machines and tunnel settings.
Q4 Is this shrink film compatible with automatic packaging machines?
Yes, this Cross Link POF shrink film is specifically designed for use on automatic packaging machines. Its consistent seal strength, low coefficient of friction (COF), and stable shrinkage properties ensure smooth, reliable operation on high-speed automated packaging lines.
Q5 Is the Cross Link POF shrink film environmentally friendly and recyclable?
Yes, this film is designed with sustainability in mind. It is recyclable and supports circular economy principles. Its lightweight construction also helps reduce transportation emissions and overall carbon footprint, aligning with global environmental and sustainability standards.
Q6 Can
custom packaging solutions be provided using this shrink film?
Yes, custom packaging solutions are available. By combining the appropriate gauge of Cross Link POF shrink film with compatible automatic packaging machines, tailored packaging can be created to match your specific product dimensions and presentation requirements, helping to make your product more attractive on the shelf.
