Regulatory Compliant Colorant Materials in Packaging and Pharma

Introduction

Regulatory compliance has become one of the most influential factors shaping the selection and deployment of colorant materials. Colorants in sectors where printed surfaces touch food or medical products either directly or indirectly, undergo a very stringent examination for migration behavior, toxicological safety, and traceability. Mainly, manufacturers are viewing compliant colorant systems as risk mitigation tools to be used without fail, instead of just option components in the formulation.

Food packaging is one of the most strictly regulated areas in terms of application. Colorants in inks and coatings need to be certified according to local regulations such as EU food contact regulations, Swiss Ordinance, and FDA guidelines. Several suppliers have thus taken to changing pigment dispersions and binders to lower the migration of substances while still maintaining the color strength and print stability. In September 2024, Sun Chemical broadened its range of low-migration packaging inks, thus, the company's commitment to packaging food contact compliance in flexible and paper- based materials continues to evolve. Sun Chemical are also raising the level of documentation pack and formulation transparency to be able to meet brand owner audit requirements completely.

Pharmaceutical packaging introduces additional layers of complexity. Besides, blister packs, cartons, and informative inserts demand colorant systems that can endure the entire storage time without any chemical interaction with active pharmaceutical ingredients. In early 2024, Siegwerk pointed out the increasing need for drug packaging ink systems that are compliant due to the tighter control from regulators and multinational drug manufacturers. Based on the company’s data, regulatory know-how and formulation traceability have been their main factors to distinguish themselves and hence getting long term supply agreements.

With global regulatory enforcement becoming more rigorous, compliant colorant materials, which were at first niche solutions, are gradually turning into baseline (standard) requirements for several printing and packaging workflows.

Major Trends, Drivers and Challenges

The strongest driver for compliant colorant adoption is regulatory risk management. Brand owners and converters currently have to go through audits more frequently not only from the authorities but also from customers. If a company fails to comply, it may have to recall the product, pay the fine, or even lose its supplier status. As a result, colorant systems with proven compliance credentials are being specified more even at the stage of purchase.

Another reason is the standardization of supply chains globally. Multinational companies want to unify the materials for packaging they use in different regions so that they can cut complexity and approval time. This creates the need for colorant materials which meet the most stringent regulatory standards, thus, allowing global use without any reformulation. Suppliers that align with European regulations often gain advantage in other markets due to perceived rigor.

A major trend is the integration of compliance support into supplier offerings. Colorant manufacturers are currently giving their customers access to the information they need for compliance, test results of migration, and even advisory services during the audits. This closer relationship with the supplier makes the customers reluctant to switch.

Low-migration ink systems form another trend. These systems are being used in packaging and labels of flexible nature. These systems are increasingly adopted in flexible packaging and label applications where food contact risk is indirect but still regulated. Suppliers are increasingly continuing to perfect their ability to balance the compositions of resin and pigment that would lead to minimized extractables while also maintaining press performance.

Challenges remain substantial. Creating colorant systems that are compliant with regulations involves lots of testing which in turn raises R&D costs and delays the launch of products. Small suppliers might have difficulties in getting all the documentation and testing done thus the market might get concentrated in the hands of the major players.

However, as regulatory compliant colorant materials are becoming essential inputs in sensitive applications, suppliers who can deliver not only regulatory compliant colorants but also combine formulation know-how with regulatory knowledge and transparent documentation are the ones who will be able to capture sustained demand as compliance requirements keep increasing.
