Our Xtend® bulk carton box/crate liner solutions are available in a range of sizes to fit traditional cartons and crates commonly used for packing and transporting of fresh produce. We offer solutions suitable for both manual sealing with rubber bands and heat sealing, depending on your operational needs.
The modified atmosphere (MA) / modified humidity (MH) properties effectively reduce dehydration, weight loss and quality deterioration during long storage.
Each bag is customized to deliver superior moisture management, condensation control, and optimal modified atmosphere conditions tailored to your specific produce type and storage profile. Learn more about our carton liner solutions below, or reach out to our team for a quote.
