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 are introducing them now, well ahead of the legal obligation, as part of our ambition to deliver the world's most sustainable food package*.

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, will come into force in 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. During 2023, we sold more than 6 billion caps with 7 different solutions under deployment and more to come, as we strive to our goal of completing the conversion ahead of the legal obligation set for July 2024.

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, also for 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’s available in multiple colours so it can fit seamlessly with 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 38mm ensures a smooth, even liquid flow, and it’s available in multiple colours so it can fit seamlessly with any packaging design. There is also a plant-based version of the cap available, which is made from polymers derived from sugar cane. This option increases the total amount of renewable content, which results in an expected CO2 reduction when compared with standard packaging.

LightWing™ 30

The LightWing™ 30 is a new flip cap concept with a self-locking hinge, developed to provide convenience for in-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. Available in several different colours, there is also a plant-based option using polymers derived from sugarcane, increasing the product's overall renewable content.
