Bio-based materials, wide-mouth and microwave-safe designs will drive the next upgrade.

A wine bag in box keeps wine contained through three coordinated parts: the bag, the box and the tap. The multi-layered film blocks oxygen, light and moisture, while a heat-sealing process creates a hermetic seal that holds under pressure.

This guide explains each layer of leakage prevention and introduces KODY PACK bag in box options, including the 220L aseptic tap bag in box.

Oil bib bags with tap (bag-in-box) hold food-grade oil in a flexible inner bag inside a rigid box and dispense it through a tap. Store them upright, away from heat and sunlight, with the tap capped, check for leaks regularly, and rotate stock first-in, first-out.
