The inner bag in a Bag-in-Box system is a marvel in modern bulk liquid packaging, designed to hold and protect the liquid securely. The bib pouch serves as an essential barrier against air, light, and other contaminants, ensuring the quality and freshness of the contents are maintained.
BIB Pouch Material Composition and Quality
The bag is typically a composite of two layers: an inner layer of single PE film for direct contact with the liquid, and an outer layer of laminated film. This laminate can either be metallic PET for opacity or transparent, depending on the specific needs of the liquid being packaged.
The bag in box packaging materials used are selected for their barrier properties, ensuring durability and a leak-proof experience.
In the spirit of environmental stewardship, there's a growing focus on incorporating biodegradable and BPA-free materials, reflecting a commitment to sustainability..
