Closing the loop & reuse of ocean bound plastic
One of the biggest challenges in achieving circularity is to implement sustainable solutions that will effectively close the loop of plastic packaging within one and the same packaging application segment. On another level, the vast amount of ocean-bound plastic litter in coastal areas requires fast action to prevent it from polluting our oceans and return it into the material stream of new packaging products.
- KIND® Healthy snack bar wrappers: SABIC joined forces with MARS and Landbell in a closed-loop project on KIND’s healthy snack bar wrappers based on certified circular SABIC PP. Advanced recycling of mixed post-consumer plastics collected by Landbell is used to produce food-contact approved certified circular PP and converted into flexible BOPP packaging structure. This mono-material application facilitates end-of-life recycling in existing collection and conversion operations without compromising quality and processability. Read more.
- Mess-free, portionable and microwavable Heinz Beanz Snap Pots: In an innovative recycling trial designed to close the loop on soft plastic food packaging in the UK, Heinz, Tesco, Berry Global and SABIC have teamed up to create a certified circular PP solution for Heinz Beanz Snap Pots. Soft plastic packaging waste is returned by consumers to collection points at Tesco stores and then converted in an anaerobic process to oil. SABIC uses the oil in the production of new PP resin, from which Berry Global manufactures Snap Pots for filling with Beanz and delivery to Tesco. The new tubs contain 39% of certified circular SABIC PP. The solution has won a silver award from Dow's Packaging Innovation 2022 Awards and it is shortlisted for the UK Environmental Packaging 2023 Awards. Read more.

Transportation packaging solutions
In most developed global supply chains, an estimated 4% of transported goods are damaged in some form during transport. For brand owners, manufacturers and carriers to minimize their losses due to this problem, materials used in transport packaging must provide enhanced protection and load stability. At the same time, they must also offer superior processing characteristics and mechanical properties for product unitization and logistic purposes.
- Stretch hoods with up to 30% PCR: Replacing traditional ethylene vinyl acetate (EVA) elastomeric containing structures, SABIC’s mono-PE stretch hood solution uses a blend of COHERE™ (POP) and SUPEER™ (mLLDPE) resins to achieve the right balance of stretchability, stiffness and holding force. In use at the company’s own plant in Genk, Belgium, these stretch films have a post-consumer recycle (PCR) content of in the range of 30%, which results in a carbon emissions reduction potential of about 20%. The SUPEER material is also available in certified renewable grades with second-generation bio-based feedstock, further reducing the carbon footprint. Read more.
- Collation shrink film with enhanced visual appearance: Sustainable shrink films designed for recycling and reduced use of virgin feedstock must maintain stringent food packaging standards with no compromise in transparency and gloss. SABIC has developed collation shrink film solutions based on SABIC LDPE and SUPEER mLLDPE resin grades that combine ease of processing, optimal shrinkage, high holding force and puncture resistance with excellent surface gloss and transparency. Both polymers are also available with certified renewable content from second-generation bio-based feedstock. Read more.
