Food is food for safety first. With the continuous development of the packaging industry, people pay more and more attention to the safety and convenience of packaging. Bag-in-box packaging, referred to as BIB box packaging, is the most successful packaging form in the global innovative packaging in recent years. Because of its hygiene, safety, convenience and environmental protection features, it has rapidly developed into a consumer in the European and American markets, and consumers are willing to choose it as the beverage packaging.

Bags in a box have been widely used in liquid packaging in various fields such as wine, juice, drinking water, food additives, medical drugs, liquid pesticides, fertilizers, and so on, for they can prolong the preservation time of liquid food to one month. Do you know its BIB preservation principles? Here Kaiguan Packaging   shares the basic preservation principles of a bag in box.

Starting from the filling, every step and every link plays a crucial role. In addition, the packaging material and structural features of the BIB system determine the realization of the role.

Let’s take wine as an example.

The bag in a box is a fully closed system before filling the wine into it, and is also in a closed cycle while filling on the filling line. The BIB will be vacuumed to ensure the removal of air inside it. After filling, a barrier system consisting of high barrier materials EVOH and MPET and a specially constructed valve ensures that oxygen is not allowed to pass through, thus ensuring a vacuum environment without air inflow into the bag.

When the valve is opened for use, the atmospheric pressure pressures the wine out of the bag, and the film automatically closes up due to the lack of air inflow into the bag, which better squeezes the bag and allows wine to be completely out of the bag without any residual. What’s more, BIB wine packaging is more convenient to use than the bottle, for its valve is easy to open and access, eliminating the use of corkscrews to pull open the cork. BIB packaging costs only 1/3 of the bottle, greatly reducing resource consumption.
