At CIRCPACK we can perform wash, pulping, NIR, fiber loss, glue removal, sink float separation and transport & friction tests.
Laboratory tests are often a requirement to receiving a recyclability certification. If, for example, there are film or paper labels are added to a plastic packaging, under the RecyClass protocol it is required to check if the inks are bleeding, if the adhesive separates the label or if a paper label is used if there is fiber loss during the reprocessing which hinders its recyclability.
At CIRCPACK we either run these test ourselves of have accredited partners to do so.
We can perform the following lab tests:
1. Cepi 3.0 Pulping test: This test will stimulate an average regular paper-mill recycling process, based on the Cepi 3.0 testing methodology.
We map your question (wash performance, pulpability, friction behaviour, NIR signal) to the relevant EN, CEPI or RecyClass test protocols. You get the protocol list before sampling starts.
Minimum 200g flake or 30 intact units depending on test. We coordinate logistics, customs, and chain-of-custody documentation across the six European offices.
Wash tests, pulping tests, sink-float, NIR-recognition, friction and LAB-value measurements. Each test is timestamped and photo-documented for the final report.
A signed PDF with raw measurements, pass/fail against the relevant guideline thresholds, and CIRCPACK interpretation. Feeds directly into RecyClass, CERTIFY or RECY:CHECK certification files.
Lab tests answer the questions that operational sorting tests cannot — and the questions that desk studies are not specific enough to settle.
Validate a new adhesive, ink, or barrier coating against recyclability thresholds before scaling production.
Benchmark a candidate resin or fibre against incumbent specs with reproducible lab data.
Close lab-test gaps in a RecyClass, CERTIFY or RECY:CHECK file before the formal audit window opens.
Send us your packaging spec and we'll come back within 48 hours with a scoped quote and timeline.
It depends on your packaging format and the certification you are targeting. For PE flexibles we typically combine a wash test with NIR-recognition; for fibre we run a CEPI pulping test. We scope the protocol in a 30-minute call before any sampling.
Most campaigns deliver in 3–5 weeks from sample receipt. Single-test rush jobs (wash test only, for instance) can return in 10 working days.
Yes. CIRCPACK is an accredited certifying body for RecyClass and RECY:CHECK, and our lab reports are formatted to slot directly into the certification evidence package — no rework required.
