Weidenhammer: Gastight composite cans with peel-off top
Suitable for use with baby milk powder, coffee, and other food products that require special protection, hygienic production, and/or oxygen scavenging, the Peel-off Top composite can from Weidenhammer Packaging Group (WPG) features a special metal closure attached directly to the body of the can that is said to equal other gastight packaging solutions.
The Peel-off Top looks like a standard tin can closure and is used in the same way while considerably increasing the high-barrier properties of the composite cans. Along with its barrier properties and consumer convenience, the composite can with Peel-off Top offers marketing advantages. Wrap-around labels can be customized to create an eye-catching product presentation.
Spiral-wrapped cans are being used to successfully package baby milk powder. The cans have an aluminum lining and a tinplate base to fully protect the sensitive product from external influences. These cans are sealed gastight with a flat tab Peel-off Top, which is similar to other standard can closures and can be easily, intuitively opened. A resealable plastic overcap provides product protection after the first opening.
To meet the highest hygiene standards and ensure maximum product safety, WPG developed and implemented a special hygiene concept for the production of composite cans for baby milk powder. In addition to clean room production, this includes ultraviolet sterilization of all composite cans.
A Peel-off Top can has also been developed for ground coffee where aroma protection is important. The composite can, that is said to be 100% gastight, protects coffee aroma, taste, and freshness. The packaging solution offers maximum protection across the entire product life cycle and increases the shelf life of the coffee even after it has been opened. The composite can is also available with an optional valve to degas the coffee.
