Frequently Asked Questions (FAQ)
❓ What is Cross Link POF shrink film and what makes it different from regular POF?
Cross Link POF (Polyolefin) shrink film is a type of shrink wrap that undergoes a cross-linking process, which creates stronger molecular bonds. This results in superior tensile strength, better tear resistance, firmer sealing, and a more uniform, attractive shrink appearance compared to standard POF film.
❓ What gauges (thicknesses) 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 gauge offers slightly different tensile, tear, seal strength, and optical properties to suit various packaging requirements.
❓ What industries is this shrink film most suitable for?
Cross Link POF shrink film is widely used across many industries. It is particularly popular in the high-end cosmetics and electronics industries due to its excellent optical clarity and professional finish. It is also suitable for food, pharmaceuticals, stationery, and general retail product packaging.
❓ At what temperatures does this film shrink effectively?
This film demonstrates effective shrinkage across a range of temperatures. Free shrinkage begins at 100℃ and increases significantly up to 130℃, achieving up to 81% shrinkage in both TD and MD directions. It is compatible with standard hot wire seal packaging machines.
❓ Is this shrink film eco-friendly and recyclable?
Yes. This cross link POF shrink film is designed with sustainability in mind. It is recyclable and supports circular economy principles, helping to reduce plastic waste. Its lightweight design also contributes to lower transportation emissions and a reduced overall carbon footprint.
❓ Can packaging be customized using this shrink film?
Yes. Packaging customization is available. By combining an automatic packaging machine with this shrink film, products can be wrapped in a tailored, visually appealing manner that enhances product presentation and brand image, making your products more attractive on the shelf.
