Get to know White Cavitated Films
White cavitated films are flexible packaging made using Biaxially Oriented Polypropylene (BOPP), sometimes polyethylene terephthalate, and a mix of other polymers on the market. White cavitated films are specifically designed for the food industry, mostly found on ice cream, chocolate bars, and bottle labels. The name comes from the tiny holes created during filming, called micro cavitation, which contributes to its distinctive white color and imparts a range of beneficial properties.

Since it is designed for food-related purposes, white cavitated films are also engineered to be compatible with pressure-sensitive adhesives and printing inks. The white color provides excellent opacity and brightness, delivering high-quality prints for high-definition graphics and text which are integral to promoting products at the store.
These films also help extend the shelf life of perishable goods, protecting them from harmful UV lights and humidity that may ruin the freshness and quality of these products. They also contribute towards reducing food waste by ensuring that products remain safe and consumable for longer periods.
