What Is Bag in Box (BIB)? Liquid Packaging Explained
Bag in Box (BIB) is a liquid packaging format in which a flexible inner bag is sealed inside a rigid outer carton and emptied through a built-in tap or valve. BIB delivers strong puncture resistance, seal strength and durability, is available in 2L to 25L sizes, and is used to store, transport and serve juices, dairy products, condiments and non-hazardous chemicals.
How a Bag in Box Container Is Built and How It Works
A Bag in Box container combines a flexible, collapsible inner bag with a sturdy outer cardboard carton, and the inner bag is commonly manufactured from a synthetic film and secured inside that carton. The BIB inner bag carries a built-in tap or valve that makes dispensing simple and minimizes mess, while the air-resistant and light-resistant bag protects the contents and keeps them fresher for longer.
Why Bag in Box Packaging Is Considered a More Sustainable Option
A BIB container requires significantly less material than rigid bottles, which reduces the amount of plastic and other raw materials that go into landfills. A BIB package is also lighter than glass bottles, which lowers shipping costs and energy use, making bag in box packaging a strong option for businesses concerned with environmental impact and waste reduction.
Bag in Box Sizes and Typical Applications
- Capacity range: 2L to 25L
- Inner bag material: food-grade LDPE film
- Sealing technology: CDF1 Smart Seal Technology
- Certification levels: UN level two and level three bag in box packaging
Guangdong Kody Packaging supplies BIB containers from 2L to 25L for storing, transporting and serving liquids. These BIB containers are made with premium materials including food-grade LDPE film and can be customized to specific product requirements, serving foodservice and industrial applications such as dispensing laundry detergent into washing machines or pouring sulfuric acid into dry cell batteries.
Where Bag in Box Is Used in Beverage and Household Care
Bag in box is an excellent choice for beverage and food production and is often used as a replacement for syrup at soft drink fountains in restaurants and other casual dining establishments. BIB is also a popular choice for storing and serving laundry detergent, because the built-in tap lets consumers disperse the right amount of product into a washing machine without spilling or overfilling.
UN Certified Bag in Box for Transporting Dangerous Goods
For applications that demand even greater durability and reliability, Guangdong Kody Packaging offers UN certified bag in box packaging, and its level two and level three BIB packages provide a safe and economical way to transport liquids that require rigorous testing and certification to meet United Nations standards for dangerous goods.

Q: What liquids can a bag in box container hold?
A: Bag in box containers store, transport and serve juices, dairy products, condiments and non-hazardous chemicals, and BIB is widely used for soft drink fountain syrup and laundry detergent. In industrial settings, BIB containers are also used to pour sulfuric acid into dry cell batteries.
Q: Is bag in box packaging more environmentally friendly than plastic or glass bottles?
A: In terms of material use, a BIB container requires significantly less material than rigid bottles, which reduces the plastic and other raw materials sent to landfill. In terms of shipping, a BIB package is lighter than glass bottles, which helps lower shipping costs and energy use.
Q: What sizes are available, and is there certified bag in box packaging for dangerous liquids?
