Recyclability increased with polyethylene closure system
Procter & Gamble’s ‘Single Unit Dose laundry pouch pack’ is compatible with the European flexible polyethylene (PE) stream recycling, an independent laboratory confirmed. The recycled material can be now used back in high-end, or even closed-loop applications.
With the initial testing of a laminated multilayer pouch containing a polypropylene (PP) closure, representing 4% of the total weight, Procter & Gamble redesigned the PP-slider with a polyethylene (PE) zipper following RecyClass recommendation. Taking into consideration this major design improvement, RecyClass revised the original approval granted to P&G and upgraded the final class ranking of the mono-material pouch to class B, following the RecyClass Methodology.
The laboratory analysis of the ‘Single Unit Dose laundry pouch pack’ with the PP slider which carried according to the Recyclability Evaluation Protocol for PE films show that the pouch conforms to the current European coloured PE film recycling stream under specific conditions which, among others, determine a limit for the PP content, as PP components downgrade the quality of the recycled PE. Moreover, the sorting behaviour was assessed by Suez.Circpack® according to the RecyClass Sorting Protocol, demonstrating that the pouch is sortable within the PE flexible stream.
This approval is yet another example of how innovation and adapting different design elements in line with the recyclability principles contribute to improving plastics packaging’s circularity.
