In today’s world, bag-in-box packaging has been applied to many accessories, like our common wine, cooking oil, sauces, juice drinks, etc., it can keep this kind of liquid food fresh for a long time, so it can keep fresh for up to a month The bag-in-box packaging of BIB, do you know what its fresh-keeping principle is?
Starting from filling, every step and every link plays a vital role. Not only that, but the packaging material and structural characteristics of the BIB system also determine the realization of this function. Take wine as an example.
Before the wine is filled into the BIB bag, it is a fully closed system. While filling on the filling line, it is also in a closed cycle, and there is a process of vacuuming the inside of the bag to ensure that the gas in the bag is removed. After the filling is completed, the barrier system composed of high-barrier materials EVOH and MPET and special-structured valves ensures the barrier to the passage of oxygen, thus ensuring that the bag is always a vacuum environment without air inflow.
When the valve is opened, the red wine in the bag is forced to flow out by the atmospheric pressure, and the film in the space inside the bag is automatically bonded due to no air inflow, which is better squeezed so that the red wine can flow out completely without remaining in the bag. In addition, BIB’s red wine packaging is more convenient to use than bottled packaging. Its valve design is easy to open and take, which saves the trouble of using a professional corkscrew to unplug the cork, and the cost of BIB’s packaging is only 1/3 of that of bottled wine. Great savings in resource consumption..
