How is boxed wine packaged?

Boxed wine, also known as cask wine or bag-in-box wine, is a packaging format that includes a plastic bag with a spigot or tap placed inside a cardboard box. The design is intended to provide a convenient and efficient way to store and dispense wine, especially in larger quantities. Here's a breakdown of how boxed wine is typically packaged:

Plastic Bag (Bladder): The wine is contained in a plastic bag, often referred to as a bladder or inner bag. This bag is specifically designed to be airtight and prevent exposure to oxygen, which helps preserve the wine's freshness for an extended period.

Cardboard Box: The plastic bag is then placed inside a cardboard box. The box serves several purposes:

It protects the wine from light, which can have a detrimental effect on the quality of the wine.

It provides structural support to the inner bag, preventing it from collapsing as the wine is dispensed.

It has a convenient dispensing system, typically a spigot or tap, usually located on one of the lower corners of the box.

Spigot or Tap: The box is equipped with a spigot or tap that allows the user to easily pour wine without exposing the remaining wine to air. The tap is often protected by a removable cap to maintain hygiene and prevent spills.

Air-Tight Seal: The box is sealed to keep air out and maintain the wine's quality. Some boxes have a built-in, resealable plastic flap that covers the tap when not in use, providing an additional layer of protection against oxygen exposure.

Boxed wine is popular for its convenience, especially for larger volumes. It's often used for everyday wines and can be a cost-effective and eco-friendly option as the packaging is generally more lightweight and produces less waste compared to traditional glass bottles. The design also minimizes the risk of spoilage since the wine is not exposed to air until it is dispensed.
