Short answer

• Buy from established European manufacturers that publish ISO certificates and food‑contact compliance: ALPLA, Schoeller Allibert, Berry Global / RPC (and other large converters like Logoplaste, Amcor). These companies supply ISO‑certified plastic bottles, jars, closures, crates and other packaging for export into Europe. (ALPLA.com)

What “ISO certified plastic packaging” usually means

• ISO 9001 (quality management) — shows the factory follows a QMS.
• ISO 14001 (environmental management) and ISO 50001 (energy) — common for larger converters.
• For food contact you also need product‑level test reports (EU migration tests, LFGB in Germany, FSSC 22000 or BRC for food safety where applicable) or EN standards for compostables (EN 13432). Don’t rely on ISO alone — ISO 9001 does not prove the material is food‑safe. See EU food‑contact and packaging buyer guidance. (ALPLA.com)

Recommended suppliers and why

• ALPLA (Austria/Europe) — global plastic packaging manufacturer; many sites publish ISO 9001 / ISO 14001 / FSSC etc and offer bottles, closures, canisters and UN-certified packs. Good for beverage, food, chemical, pharma applications. (ALPLA.com)
• Schoeller Allibert (NL/Europe) — reusable crates, containers and transport packaging; lists ISO 9001, ISO 14001 and food‑safety certificates for operations. Good for logistics/retail packaging. (schoellerallibert.com)
• Berry Global / RPC (UK/Europe, part of Berry) — many European plants publish ISO 9001 certificates; wide portfolio (rigid, thermoformed, films). Good for large volumes and branded customers. (berryglobal.com)
• Logoplaste, Amcor, Plastipak, Greif and other major converters — large footprint across Europe and often publish certificates and test capability (search each supplier’s “quality/certificates” pages). (en.wikipedia.org)

Where to source (marketplaces and broker channels)

• Direct from manufacturer websites (preferred for certificates and test reports). Use the suppliers above or local plants (many have European sites). (ALPLA.com)
• B2B directories focused on Europe: Europages, Packaging Europe supplier listings, and industry trade directories (these list certified converters and let you filter by country / product). (Search these sites for “ISO 9001 plastic packaging Europe”.)
• Specialist contract packers / co‑packers in Germany/Benelux — useful if you need small runs and regulatory support.
• Trade shows and trade associations (Interpack, K show, European Plastics Converters associations) — good for vetted suppliers.

What to request from any supplier before buying

1. Official, current ISO certificates (PDFs with scope and site name) — verify issuing body and expiry.
2. Product‑specific compliance documents:
   • EU food contact declaration of compliance (DoC) and migration test reports (if for food).
   • LFGB test reports if you’ll sell in Germany (recommended).
   • REACH/ROHS declarations for chemicals where relevant.
   • EN 13432 / OK Compost certificate for compostable items.
3. Material spec (polymer grade, % r‑PET or recyclate if applicable), melt flow, additives, colourants and any restricted substances lists.
4. Samples and third‑party lab testing if you don’t trust supplied reports.
5. Traceability data, batch numbering and quality control plans.
6. For Germany specifically: proof that packaging / EPR obligations will be covered (e.g., LUCID registration/enrollment or importer responsibilities). See German VerpackG guidance. (bioleaderpack.com)

Practical export tips (Germany / EU importer perspective)

• Food contact packaging: have DoC and migration tests handy at customs and for buyers — many purchasers will not accept shipments without them. (cbi.eu)
• EPR / packaging law: if you place packaged goods on the German market you (or your importer) must comply with VerpackG (LUCID). Include the required labeling and waste info for the destination country. (bioleaderpack.com)
• Insist on written incoterms, lead time, minimum order quantities, sample acceptance criteria and penalty clauses for off‑spec lots.
• For compostable claims or “recycled content” claims, require third‑party certification (EN 13432, RecyClass, ISCC) and correct labelling to avoid fines for false green claims. (bioleaderpack.com)

If you want, I can

• Find and compare specific ISO‑certified manufacturers for your product type (bottles, trays, films, crates) and volume, and return contact pages and certificate links.
• Draft an email template/RFQ you can send to suppliers to request certificates, DoC and pricing.

Which would you like me to do next? (I can look up suppliers for a particular product — e.g., PET bottles, HDPE jerrycans, thermoformed food trays — and return 5–10 vetted options with links to their certificates.)
