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
TwistCap™ OSO Barrier 34 Pro
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.
TwistCap™ OSO 34 Pro
The TwistCap™ OSO 34 Pro is a fully renewable one-step resealable tethered cap available for Tetra Rex® carton packages. It is based on a screw opening mechanism with tethered strings that keep the lid attached to the package. The proportions of the closure provide a good grip and it is easy to control pouring, particularly with viscous products. It is suitable for chilled liquid dairy products (LDP) and other liquid dairy products (OLDP). This one-step opening comes with a slitted 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.
C38 Pro
The C38 Pro is a resealable and future-proof tethered cap. It is based on a screw opening mechanism and the cap stays attached to the package, helping to prevent litter. It also features a visible tamper band to make it clear when the package has been opened, helping to secure food protection. The opening size of 38 mm ensures a smooth, even liquid flow, and it is available in multiple colours, allowing it to fit seamlessly into any packaging design.
HeliCap™ 26 Pro
The HeliCap™ 26 Pro features a new screw and flip concept with a self-locking hinge after opening, providing convenience for at-home consumption. This one-step opening comes with a clearly visible tamper evidence ring, ensuring the product hasn't already been opened, while the 26 mm opening area offers a smooth liquid flow. The HeliCap™ 26 Pro has a cutter-based opening mechanism and is applied after the package is filled and formed over a pre-laminated hole in the packaging material. It is available in multiple colours, allowing it to fit seamlessly into any packaging design.
HeliCap™ 23 Pro
The HeliCap™ 23 Pro is based on a screw opening mechanism, with tethered strings keeping the lid attached to the rest of the package. A clearly visible tamper evidence ring ensures the product hasn't already been opened, securing food protection. The HeliCap™ 23 Pro has a cutter-based opening mechanism and is applied after the package is filled and formed over a pre-laminated hole in the packaging material. It is available in multiple colours, allowing it to fit seamlessly into any packaging design.
DreamCap™ 26 Pro
The DreamCap™ 26 Pro features a new screw and flip concept with a self-locking hinge after opening, for consumer convenience while drinking. This one-step opening comes with a clearly visible tamper evidence ring, ensuring the product hasn't already been opened. Designed to suit facial geometry, its 26 mm opening size ensures an optimal beverage flow, offering a comfortable drinking experience that's especially well-suited for demanding on-the-go consumers. The DreamCap™ 26 Pro has a cutter-based opening mechanism and is applied after the package is filled and formed over a pre-laminated hole in the packaging material. 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. The closure is entirely formed and applied inside the filling machine, using the direct injection moulding concept (DIMC) with no need for a cap applicator downstream. 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.
