Convenience and longevity are key features that manufacturers seek to develop in packaging. For beverages such as wine, glass bottles have long been the preferred packaging choice, but one type of storage that offers a convenient and clean way to store and dispense wine, whilst extending product life, is the bag in box option.

Often referred to as a ‘plastic bladder’, the bag in box is an innovative way to package liquids. With a tap attached to the bag for easy dispensing,  the bag in box is most frequently used for wine and offers numerous benefits for manufacturers and consumers.

How it Works

The bag in box packaging consists of a bag, which sits safely inside a cardboard box and is usually made from layers of plastic or metallised film. The bag can hold large volumes of liquid, and is popular among manufacturers and consumers for this reason. To fill the bag with liquid, the manufacturer removes the tap, fills the bag and then replaces the tap to close the bag. A cardboard box then encases the bag for protection, with the end consumer revealing the tap by ripping along a perforated section of the cardboard. Liquid is dispensed when a button or lever on the tap is pressed.

The bag in box with a tap has four main advantages when compared to traditional glass packaging for wine:

  1. It’s considered to be more eco-friendly. The bags are designed to store large volumes of liquid so less packaging is needed overall. As it’s made from plastic and cardboard, the bag in box with tap is also particularly light, which makes it cheaper and easier to transport. Given its angular shape, the bag in box with tap can easily be stored on a shelf or in the fridge – all that’s needed is a flat surface for it to sit on, and the conventional shape means they stack with ease.

  1. Products last longer. Unlike traditional glass bottles for wine, wines stored in a bag in box don’t come into contact with oxygen until dispensed, and can therefore last for up to 4 weeks once the tap has been opened. Although previously used for inexpensive wines as it was cheaper than glass, nowadays, many wines are sold in a bag in box as they have a longer life once opened and keep the wine in good condition. They’re also a great option for events where larger volumes of wine are needed.

  1. Easy dispensing. Thanks to an attached tap, dispensing liquids couldn’t be easier. The tap is simply pressed to dispense liquid, and released when the required amount is in the glass. Different tap options are available depending on the liquid being dispensed.

  1. No spillages. The dispenser tap mechanism opens and closes when pressed, and with a glass held underneath, liquid cleanly flows directly into the glass. Even if the box is knocked over, the risk of spillages is minimal thanks to its clever design and convenient operation. This means less product waste overall.

The bag in box with tap is becoming an increasingly popular form of packaging. Frequently used by wine manufacturers, other products are starting to make use of the tap dispenser mechanism.
