What Are Tethered Closures and Why Are They Required in Europe?
Tethered closures are bottle caps designed to remain attached to beverage containers after opening. Unlike traditional caps that can be fully removed, tethered closures stay connected to the bottle during use, helping keep the cap and container together throughout the product lifecycle.
Under Article 6 of Directive (EU) 2019/904, single-use plastic beverage containers with a capacity of up to three liters may only be placed on the EU market if their plastic caps and lids remain attached to the containers during the intended use of the product.
The purpose of this regulation is not necessarily to reduce the amount of plastic used in each closure. Instead, it aims to reduce the risk of caps becoming separated from bottles, being discarded as litter, or being lost before entering the recycling stream. By keeping the cap and bottle together, tethered closures help support more consistent collection, sorting, and recycling of beverage packaging.
As sustainability regulations continue to influence beverage packaging design, tethered closures are becoming an important standard for PET bottle packaging, beverage manufacturing, and plastic cap production in the European market.
What Are Tethered Closures?
Tethered closures are plastic bottle caps that remain connected to the bottle after opening through an integrated hinge or retention system.
Unlike traditional bottle caps that can be completely separated from the container, tethered caps stay attached during consumption and disposal.
These closures are widely used for:
- Bottled water
- Carbonated soft drinks
- Juice beverages
- Dairy beverages
- Sports drinks
- Functional beverages
Today, many beverage production companies and plastic cap manufacturers are redesigning packaging systems to support tethered closure applications.
