The sealing lid has a long-standing history in the packaging industry and is currently experiencing a renaissance. For over 25 years, Greiner Packaging has been offering innovative solutions with sealing lids that allow direct sealing of cups without the need for an additional foil seal. This approach has proven itself over the years and is now being perfected with the new Click In sealing lid. It sets new standards in flexibility, usability, and sustainability – offering a future-ready solution for modern packaging needs.

The sealing lid: Innovation that locks in!

Greiner Packaging has long offered sealing lids that eliminate the need for a third component – a foil lid. By reducing the materials from three to two components, both the cup and the lid can be made from the same material, such as PP or PET. This saves resources, simplifies the packaging process, and improves recyclability. With the Click In sealing lid, Greiner Packaging is taking it a step further – setting new benchmarks in flexibility, safety, and environmental responsibility. Compared to traditional sealing lids, the Click In lid requires only a small inward embossing on the cup to stay securely in place. Once clicked on, it stays put and reliably protects the contents – even if the cup is accidentally tipped over. A particularly practical feature: when re-closing the cup, users hear a clear “click,” confirming the lid is securely in place and the cup is leak-proof again.

What Makes the Click In Lid Stand Out:

Secure fit for reliable leak protection: Thanks to its innovative click technology, the Click In lid stays firmly on the cup when re-closed. This ensures that even after the first opening, the cup remains tightly sealed and the product stays well protected at all times.
Sustainability through mono-material: Doing away with a separate foil lid significantly reduces material usage and carbon footprint. The Click In lid can be produced from the same material as the cup (e.g. PP or PET), enhancing recyclability and contributing to more sustainable packaging solutions.
Design freedom in shape & decoration: The Click In lid impresses with exceptional versatility. It fits almost any cup, regardless of shape or size. Whether round, square, or rectangular, whether thermoformed or injection-molded, its intelligent design allows it to adapt to various cup types and diameters. It also provides maximum creative freedom: the cup can be decorated in many ways – even right up to the sealing edge. This allows for highly customized and visually appealing packaging.

What consumers love about it:

The Click In sealing lid offers numerous practical benefits for consumers. Unlike traditional packaging with an aluminum foil and snap-on lid, there's no need to remove a separate seal. The lid is simply taken off and placed back on after use – quick and easy. Additionally, the lid protects the product from external influences like moisture or contamination, helping extend shelf life. This means the contents stay fresh and enjoyable for longer – a real benefit for both consumers and manufacturers. Another plus: the audible “click” that signals the lid is properly sealed and the product remains safely protected after opening.
