RecyClass tested and granted approval for low-density polyethylene (LDPE) film technology using LyondellBasell’s ‘Toppyl PB 8640M’ and ‘Toppyl PB 8340M’ as well as compounds that contain one of these two polymer grades and falling into the tested structure. The technology is fully compatible with the low-density polyethylene recycling stream.
‘Toppyl PB 8640M and PB 8340M’ technology aims to exhibit a cohesive peel mechanism within the film structure with a chemical compound containing Polybutene-1. The tested technology was incorporated in an unprinted three-layers LDPE film while representing 7.5% of the total weight of the film.
The laboratory analysis, of this additivated film, was carried out by an independent laboratory Proplast which carried out the tests as per the RecyClass Recyclability Evaluation Protocol for PE films. The results demonstrate that this technology will have no negative impact on the current European PE flexibles recycling stream under specific conditions. To be fully compatible the film structures incorporating this technology must, among others, have a density below 0.97 g/cm3 and where ‘Toppyl PB 8640M and Toppyl PB 8340M’ do not exceed 7.5% of the total weight of the structure.
The laboratory testing shows that plastic generated by the recycling process may be used in high-quality applications such as PE blown film with up to 25% of this material.
The proliferation of new technologies for flexible packaging in line with the design for recycling principles shows a strong commitment of the value chain actors to improve the recyclability of this stream on the way to increasing the overall recycling targets in the EU.

RecyClass Recyclability Approvals
RecyClass issues two types of Recyclability Approvals – Technology Approvals and Product Approvals. These are issued upon conducted testing in accordance with one of the established Recyclability Evaluation Protocols. Testing results are incorporated in the RecyClass Design for Recycling Guidelines and the Online Tool. The full list of approved Technologies and Products can be found on the RecyClass website.
