BaginBoxSysteme

BaginBoxSysteme, commonly called Bag-in-Box packaging, is a method for containing liquids in which a flexible plastic bag sits inside a rigid outer carton. A dispensing tap on the bag allows controlled pouring, while the carton provides protection, light shielding, and easy handling. It is used for wines, juices, oils, and other liquids.

Design and materials: The inner bag is typically multi-layer polymer film with a barrier layer (for example EVOH) to limit oxygen transmission. The outer carton is usually corrugated cardboard. A dispensing tap or valve is attached to the bag or carton; some systems include tamper-evident features. Standard sizes range from 1 to 5 liters for consumer use, with larger formats for bulk distribution.

History and usage: The concept emerged in the late 20th century and gained wide adoption in wine packaging from the 1980s onward. BiB reduces breakage risk, weight, and space in transport and storage compared with glass bottles, and minimizes light exposure that can affect quality. After opening, product longevity depends on the product and seal integrity.

Environmental and industry notes: The outer carton is typically recyclable paperboard, and the inner bag materials are designed to be recyclable in some jurisdictions. The Bag-in-Box concept is supported by industry groups and standards that address barrier performance, seal integrity, and dispensing reliability to facilitate shelf-stable products and consumer safety.
