If you sell PET flake or rPET, your buyers are the companies that extrude PET sheet and thermoform it into trays, clamshells and blisters. The hard part isn't searching — it's separating real producers from directories, machine builders and recyclers that only sell flake.
1. Search in the local language
An English query fired into a foreign Google returns almost nothing. "PET-Folie Hersteller" in Germany, "lastra PET produttore" in Italy, "PET levha üreticisi" in Turkey surface the domestic manufacturers that never rank in English. This alone roughly doubles real coverage.
2. Read the website, not the snippet
A company that lists "sheet extrusion," "APET/RPET," "thermoforming," "trays" and "clamshell" is a buyer. One that talks about "we recycle," "rPET granules for sale" or "regranulate" is a competitor. The only reliable way to tell is to read each site and weigh the vocabulary.
3. Keep the evidence
For every company, keep the matched keywords so you can audit why it qualified. That's exactly how Fiorentis works — it reads each site live and shows the evidence behind a green/yellow/red score.
