What is a bag in a box？

1、 Fundamental Deconstruction: Definition and Core Composition of the Bag in a Box.

Core definition: bag in box (BIB) is a composite packaging system consisting of a flexible inner bag, a hard outer box, and a dedicated valve.

It is designed specifically for liquids and semi fluids, and achieves long-term liquid storage and convenient access through barrier protection and structural support. ​

2、 Deep Exploration of Value: Triple Advantages of Cost Reduction, Freshness Preservation, and Environmental Protection.

Economic cost advantage: The cost of packaging materials per unit capacity is only one-third of that of bottled bottles, and the amount of consumables for 3L red wine packaging is much lower than that of glass bottles of the same capacity; Empty Bags can be folded, with a pallet loading capacity 80% higher than bottled ones, reducing logistics and warehousing costs by over 35%. ​

Functional and practical advantages: multi-layer barrier film+vacuum packaging, with an unopened shelf life of over 1 year, and can still be preserved for 1-2 months after opening; Suitable for various processes such as aseptic, hot and cold filling, the same equipment can process 2-1400 liters of products of different specifications. ​

3、 Practical Guide: Scene Adaptation, Selection, and Key Points for Avoiding Pits

Segmented scenario adaptation: Food and beverage (use aluminum plated bags to avoid light for red wine and juice, and choose 22L large capacity edible oil); Medicine (sterile inner bag packaging reagents); Agriculture (corrosion-resistant bags containing liquid fertilizers); Catering retail (small capacity models suitable for ready to drink coffee and smoothies).
