Frequently Asked Questions (FAQ)
Q
What is hot perforation POF shrink film?
Hot perforation POF (Polyolefin) shrink film is a food-grade packaging material with micro-perforations created through a hot-needle process. These perforations allow air circulation, making it ideal for packaging fresh food products such as eggs, fruits, and vegetables while maintaining product freshness.
Q
What gauge thicknesses are available for this POF shrink film?
The hot perforation POF shrink film is available in five standard gauge thicknesses: 12um, 15um, 19um, 25um, and 30um. Each thickness offers different tensile strength, tear resistance, and shrinkage properties to suit various packaging requirements.
Q
Is hot perforation POF shrink film safe for direct food contact?
Yes. The film is made from food-grade, non-toxic, and odorless polyolefin materials, making it completely safe for direct contact with food products including eggs, fresh produce, and baked goods.
Q
At what temperatures does this shrink film perform best?
The film demonstrates effective shrinkage properties across a temperature range of 100℃ to 130℃. At 130℃, free shrinkage reaches up to 67% (TD) and 68% (MD), providing strong and reliable packaging results across a wide range of industrial shrink tunnels and equipment.
Q
Can the perforation pattern be customized?
Yes. The perforation pattern and density can be customized to meet specific packaging needs. Different perforation designs are available to optimize breathability depending on the type of product being packaged.
Q
Is hot perforation POF shrink film environmentally friendly?
Yes. The film is recyclable and manufactured with an eco-friendly approach. It supports sustainable packaging practices by minimizing waste and environmental impact, contributing to a circular economy while still delivering excellent packaging performance.
