Buyer ESG audits often begin with a simple request: “Please send the certificate.” In practice, a single certificate is rarely enough. Packaging suppliers need an evidence pack that explains what the packaging is made of, how it can be recycled, and which regulatory or customer requirements it can address.

For paper packaging suppliers, questions about FSC, PEFC, material composition, recyclability, EPR, PPWR, and restricted substances can arrive together. If an audit is 30 days away, the fastest preparation is to divide the file into three document packs: raw material evidence, recyclability evidence, and regulatory response evidence.

Packaging supplier preparing document packs for a buyer ESG audit

Pack 1: raw material and supply chain evidence

The first pack explains what the packaging is made from. It includes paper, corrugated board, adhesives, coatings, inks, labels, and auxiliary materials. FSC or PEFC certificates may also belong here.

The important point is scope. FSC is useful evidence for responsible fibre sourcing, but it does not prove recyclability or PPWR compliance by itself. Use it as sourcing evidence, and prepare separate records for recyclability and substance control.

This pack should include:

  • product specification and drawing
  • material composition table
  • paper or corrugated board supplier documents
  • FSC or PEFC certificate and applicable scope
  • adhesive SDS/MSDS
  • lot memo if suppliers or inner papers vary by production lot

Pack 2: recyclability and packaging minimisation evidence

The second pack explains whether the package fits the intended recycling stream. “Paper-based” is not enough. Coatings, laminates, windows, metal parts, adhesives, inks, and contamination can all affect recyclability.

A practical self-assessment should record single-material structure, composite parts, detachable components, coatings, water or grease resistance, contamination risk, and local disposal route. If available, add target-market guidance or repulpability evidence.

Packaging minimisation should also be included. ESG audits may question excessive void space, unnecessary cushioning, or over-specified board strength. If reducing the package would create product damage risk, explain the protective function and strength basis.

Pack 3: regulatory response and customer communication history

The third pack covers PPWR, EPR, restricted substances, and customer-specific forms. The goal is not to claim that every document already exists. The goal is to separate what is available, what is under review, and what would require additional testing.

For PPWR, do not treat the question as a request for one universal certificate. Break it down into material composition, recyclability, restricted substances, information duties, declaration, and technical documentation. For EPR, connect the file to packaging reporting, fee exposure, material structure, and recyclability evidence.

Restricted substance evidence depends on customer expectations. Supplier declarations and SDS documents may be enough at an early stage. If the customer form asks for numerical values for heavy metals, PFAS, REACH SVHC, or RoHS, accredited test reports may be necessary.

A 30-day preparation schedule

D-30 to D-21: build the document list

Create a product-by-product index. Include specifications, composition tables, paper evidence, FSC or PEFC documents, SDS/MSDS, test reports, recyclability review, and customer communication history. Mark missing items as “to be confirmed,” not simply “not available.”

D-20 to D-11: request supplier evidence

Ask suppliers for paper, adhesive, coating, and printing evidence. If raw materials vary by lot, confirm the current manufacturing basis. Outdated certificates or certificates with the wrong scope can create problems during an audit.

D-10 to D-1: prepare the customer submission set

Too many files can be as confusing as too few. Make an index file and connect each evidence document by number. Separate available documents, pending documents, and items that require additional testing.

A useful question to send before the audit

Please confirm whether the requested packaging ESG and PPWR documents should cover raw material/FSC or PEFC evidence, recyclability assessment, EPR-related records, restricted substance test reports, a declaration, or your own customer-specific form. If test items and acceptance criteria are required, please share them in advance.

This question can prevent unnecessary testing and focus the work on the documents the buyer actually needs.

Summary

In an ESG audit, traceable evidence matters more than polished wording. Paper packaging suppliers can answer most early buyer questions by organising documents into raw material evidence, recyclability evidence, and regulatory response evidence.

FSC and PEFC are useful supporting documents, but they are not the whole file. A complete packaging evidence pack also needs material composition, recyclability review, substance records, and communication history.
