SUSTAINABLE LIQUID PACKAGING

A major advantage of the bag in box system is its eco-friendliness and low carbon footprint. It’s common knowledge that, compared to a glass wine bottle for example, bag in box packaging is much less energy-intensive to produce and far more efficient to recycle. The first exhaustive study on the environmental impact of different packaging types was conducted in Sweden and Norway. The result: a 3-litre wine box beat a glass wine bottle in all aspects, generating on an average less than a fifth of the CO2 emissions (17.9 %) as the same volume of bottled wine.

FAQ

1. What is bag in box packaging?

Bag in box packaging is an optimized, eco-friendly and sustainable packaging solution for liquids. It consists of two elements: a flexible inner bag and an outer box made from corrugated cardboard. The box protects against damage and exposure to light, while offering valuable space for branding and communication. The airtight bag gives the packaged liquid a longer shelf life. One 3-litre bag in box packaging generates less than a fifth of the CO2 emissions created by using four 75cl glass bottles.

2. How Do You Fill Bag In Box Packaging?

Bag material is selected according to the liquid’s properties; the bag can be filled with hot or cold liquids, manually or mechanically. Next, the corrugated cardboard outer packaging is assembled, the filled bag placed inside and the box closed. The bag in box is then complete. With its strong outer and sustainable credentials, this eco-friendly packaging solution is also ideal for direct-to-consumer shipping.

3. What kind of products are suited for bag in box packaging?

5. How many litres can bag in box packaging hold?

This type of packaging can be designed to hold anything from 1 to 20 liters of wine or other liquids.

The smallest production run for bag in box packaging is currently 5,000 units.
