BucketBox WACKER finds a way out of a sticky situation with EcoSolutions

Single-use plastics and difficult-to-recycle with silicone barriers are used widely in the chemical industry. WACKER is making continuous decisions for each single product to pack. Find out how Mondi creates more sustainable solutions.

Sustainable by mondigroup.com where possible, plastic when useful – At Mondi, we believe packaging should be sustainable by design. The next generation of high-performance industrial packaging demands inventive design that offers new options to replace less material without jeopardizing operational efficiencies. As a leading manufacturer of corrugated packaging, we are uniquely positioned to work together with our customers to find the most sustainable paper-based solution where possible.

The Challenge WACKER, a worldwide operating chemical company, had just developed a new gumbase premix for chewing gum production and was determined to find a more sustainable packaging. Production requires the to be filled with 110° C hot molasses, which turns solid after three days. Typically, non- recyclable plastic buckets and complex with thick silicon barriers are used for this type of application. Due to unsatisfying release properties and awkward handling, 3-piece corrugated solutions were not the company’s preferred choice for the new project’s functionality and sustainability needs. The aim was to find an easy-to-handle solution that was heat resistant, leak-proof, food-safe, resource efficient and fully recyclable.

Our Approach Using Mondi’s EcoSolutions approach, our team of experts worked together closely with the client to determine packaging performance needs, sustainability, as well as handling and storage criteria. Our development teams were able to draw from their experience with release function and heat resistance of linings from Mondi´s extrusion business that can be used for food contact end-uses. Mondi engineers were tasked to create a one-piece corrugated box design with no open flute that eases handling and storage, in addition to being recyclable in paper waste streams. The Solution

BucketBox is a one-piece folding corrugated solution that is BucketBox is recyclable 100 percent leak-tight to the top thanks to its highly functional and meets the following sustainable Paratherm® barrier . Beyond its resource conserving design product criteria: and excellent release properties, the food-safe solution is com- plemented by a smart solution for easy and safe opening.

Resource Enhanced Next Optimization Product Life The Result Performance

Mondi’s seamless and leak-proof BucketBox requires 30 percent less material and saves 20 seconds in erecting time compared to a 3-piece corrugated solution. The ingenious design boosts operational efficiencies. It offers a residue-free release of the gumbase premix as Paratherm® release properties proved to be a perfect fit for this project while complying with stringent less food safety standards. Moreover, it is recyclable in European 30% material* paper waste streams where silicone release face more limitations. The project also proved with high performance release properties to be a sustainable alternative for producers using ridgid plastic containers in similar applications. more product on * 40% Previous Industry Standard Mondi’s Solution * in comparison with 3-part solution * in comparison
