Tethered caps for Tetra Pak® carton packages

Tethered caps are the latest additions to our range of openings and closures, allowing you to achieve your ambitions in three essential areas – food safety, food waste, and the environment – simultaneously. We have now developed and introduced eight different solutions to ensure we deliver benefits for producers and consumers alike, from a reduced percentage of plastic to greater functionality.

Preventing litter

The EU Single-Use Plastic (SUP) Directive, which mandates that single-use beverage containers made with plastic will only be allowed on the market if their caps and lids remain attached, came into force in July 2024. The directive is an integral part of the EU's wider approach announced in their Plastics Strategy and an important element of the EU Circular Economy Action Plan. In 2021, we began the deployment of our tethered caps and, as of June 2024, we have delivered 12 billion caps reaching over half a billion consumers in Europe. We will continue to expand our tethered cap portfolio, including plant-based options using sugarcane-based polymers or ISCC-certified recycled polymers.1

The TwistCap OSO Barrier 34 Pro is a one-step screw cap with improved barrier properties against oxygen transmission for high acid ambient distribution (HAAD) and available for Tetra Rex® packages. The proportions of the closure give a good grip and good control of pouring. Suitable for ambient juices, it protects the product for 6-12 months, depending on filled product characteristics. It is based on a screw opening mechanism with tethered strings that keep the lid attached to the package. This one-step opening comes with a moulded tamper band which ensures that the product hasn't already been opened. It is available in multiple colours, allowing it to fit seamlessly into any packaging design.

LightWing™ 30

The LightWing 30 is a new flip cap concept with a self-locking hinge, developed to provide convenience for at-home consumption. The closure snaps shut for later consumption. The neck of the closure is moulded in the filling machine directly onto the packaging material using the direct injection moulding concept (DIMC). It is moulded flat against the product side of the packaging material, creating a large flat pouring area of 30 mm that delivers excellent pouring. The lid is applied downstream. It is available in multiple colours allowing it to fit seamlessly into any packaging design.

LightTab™ 30

The LightTab 30 is a one-step tethered cap based on a flip opening concept with a visible hook that helps you lock the lid in its opened position during pouring, providing convenience for at-home consumption.

This is ideal If you are looking to reduce operational complexity. A clearly visible tamper evidence ensure that the package hasn’t already been opened, and the cap is available in white.

Notes

1The certified recycled polymers used in the caps, tops and coatings of some of our carton packages are produced under the ISCC chain of custody attribution method. This means that the plastics are made of a mix of recycled and non-recycled materials, but that the corresponding mass of recycled materials has been tracked throughout the Tetra Pak supply chain.
