BPA-Free Thermal Paper in Europe: Complete Compliance Guide 2025

Thermal paper works through a chemical reaction between a leuco dye and a developer compound when heat is applied. For most of the 20th century, Bisphenol A (BPA) was the developer of choice due to its excellent thermal sensitivity, low cost, and long image stability.

However, BPA is classified as an endocrine disruptor — a substance that interferes with the hormonal system. Research published in peer-reviewed journals demonstrated that BPA can be absorbed dermally through handling thermal receipts, raising concerns about occupational exposure for cashiers and retail workers who handle receipts daily.

The EU's Scientific Committee on Consumer Safety (SCCS) concluded that BPA in thermal paper poses a risk to workers who handle receipts frequently, leading to the REACH restriction that came into force in January 2020.

REACH Regulation (EU) 2016/2235 restricts BPA in thermal paper to a concentration of 0.02% by weight (200 ppm). This applies to thermal paper placed on the EU market, regardless of where it was manufactured.

France went further with its Grenelle II law, which banned BPA in all food contact materials — including thermal paper used in food service environments. This French restriction predated the EU-wide REACH restriction and applies to all BPA-containing materials, not just thermal paper.

Importantly, the restriction applies to the finished thermal paper product, not just the raw materials. Importers and distributors placing thermal paper on the EU market are responsible for ensuring compliance, even if they did not manufacture the product.

The European Chemicals Agency (ECHA) continues to evaluate Bisphenol S (BPS) — the most common BPA substitute — for potential SVHC listing. Several EU member states have already raised concerns about BPS, and distributors should monitor developments closely.

A product labelled 'BPA-free' should contain no BPA in its thermal coating formulation. However, the term is not regulated, and some manufacturers use it loosely. Distributors should request third-party test reports confirming BPA content below the 0.02% REACH threshold, not just supplier declarations.

The most common BPA alternatives currently in use include: Bisphenol S (BPS), D8 (a phenol sulphone compound), Pergafast 201, and vitamin C-based developers. Each has different performance characteristics and regulatory status.

BPS, while widely used, is under increasing regulatory scrutiny. Distributors sourcing 'BPA-free' products should clarify whether the alternative developer is also BPS-free, particularly for products destined for food service or healthcare applications.

To demonstrate compliance with REACH Regulation (EU) 2016/2235, distributors should obtain and maintain the following documentation from their thermal paper suppliers: a BPA-free declaration signed by the manufacturer, third-party test reports from an accredited laboratory confirming BPA content below 0.02%, and a REACH SVHC statement confirming no SVHC substances above the 0.1% threshold.

For products sold in France, additional documentation confirming compliance with the Grenelle II food contact requirements may be required, particularly for products used in food service environments.

These documents should be reviewed annually and updated whenever the product formulation changes. Distributors who cannot produce compliance documentation on request may face enforcement action from national market surveillance authorities.

When evaluating thermal paper suppliers for EU market compliance, distributors should verify: ISO 9001:2015 certification covering the thermal coating process, third-party BPA test reports from accredited laboratories (not just in-house testing), clear identification of the alternative developer system used, and willingness to provide updated documentation as regulations evolve.

Price should not be the primary selection criterion for EU-market thermal paper. The cost of a compliance failure — product recalls, regulatory fines, and reputational damage — far exceeds any savings from sourcing non-compliant product.

Zhixin Paper's entire thermal paper range is manufactured without BPA or BPS. We provide full compliance documentation including third-party test reports, REACH SVHC statements, and BPA-free declarations for all products.
