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 by heat. These perforations allow airflow through the packaging, making it ideal for fresh food products such as eggs, fruits, and vegetables that require breathability during storage and transport.
Q
What gauges (thicknesses) are available for this POF shrink film?
This hot perforation POF shrink film is available in five standard gauges: 12um, 15um, 19um, 25um, and 30um. Each gauge offers different tensile strength, tear resistance, and shrinkage properties to suit various packaging requirements.
Q
Is this shrink film safe for direct food contact?
Yes. The hot perforation POF shrink film is made from food-grade, non-toxic, and odorless materials. It fully complies with food safety standards and is safe for direct contact with eggs, fresh produce, and other food products.
Q
At what temperature does this POF shrink film work best?
This film performs effective shrinkage across a wide temperature range of 100℃ to 130℃. Shrinkage rates increase with temperature — for example, free shrinkage in the TD direction reaches 23% at 100℃ and up to 67% at 130℃, providing excellent flexibility for different packaging tunnel settings.
Q
Can the perforation patterns be customized?
Yes. The perforation patterns can be customized according to specific packaging needs. Different hole sizes, densities, and distributions are available to optimize breathability and meet the requirements of various food products and packaging lines.
Q
Is hot perforation POF shrink film environmentally friendly?
Yes. Hot perforation POF shrink film is an eco-friendly and recyclable packaging material. Compared to PVC shrink film, POF film does not release harmful gases during the shrinking process, making it a more sustainable choice that supports a circular economy and reduces environmental impact.
