Bag-in-Box is a packaging system that consists of a flexible bag placed inside a sturdy box. This design allows for easy dispensing of liquids, such as wine, juice, or sauces, while protecting the contents from light and air, which can spoil them. The bag collapses as liquid is dispensed, minimizing oxygen exposure. The Bag-in-Box system is popular for its convenience and efficiency. It is lightweight, easy to store, and reduces waste compared to traditional glass bottles. Additionally, it often has a longer shelf life, making it a practical choice for both consumers and manufacturers.
