Quality Ink Drops for Label Printing and Packaging Safety

Quality Ink Drops for Label Printing and Packaging Safety

The packaging industry, particularly the food and beverage sector, has seen tremendous growth in recent years. However, this expansion also underscores the crucial role that label printing plays in product safety, brand communication, and compliance with global food safety regulations. A key component often overlooked in the label printing process is the quality of inks used, which can impact not only the aesthetic appeal but also the safety and regulatory compliance of the product.

The Value of High-Performance Inks in Label Printing

In the dynamic world of package and label printing solutions, the importance of ink quality is often understated. The selection of ink, however, is fundamental in creating high-performance, sustainable labels and packaging that align with safety standards for food, human health, and the environment, without compromising budgetary constraints.

Inks form a visible and aesthetic part of packaging that communicates a brand’s value, entices customers, and offers insight into the product’s content. In the broader context of packaging safety, inks also play a significant role. They can contribute to potential risks through a process known as ink migration.

Ink Migration: An Overview

Ink migration refers to the transfer of ink components from or through a packaging or label material into the food product. This occurrence manifests in two ways. Firstly, Penetration Migration involves the migration of a substance from the printed side, through the substrate, and onto the food. Secondly, Contact Migration or Set-off Migration occurs when a substance from the printed side migrates to the non-printed surface during the manufacture or storage of the printed item in a stack or roll.

The quality of ink drops plays a vital role in managing and minimizing the risk of ink migration. High-quality inks reduce the chances of these migrations, ensuring that labels and packaging comply with safety standards and protect the end consumer.

Regulatory Guidelines for Inks in Food Packaging

The United States Food and Drug Administration (FDA) and European Food Safety Authority (EFSA) regulate the safety of substances used in Food Contact Materials (FCMs). Each layer in the packaging—be it the substrate, label, adhesive, or ink—constitutes its own FCM and falls under these regulations.

While these bodies regulate FCMs, they don’t certify individual layers or a complete food contact article (FCA). Even though ink is not meant to come into contact with food, it lacks specific certification or a harmonized regulation from the FDA or EU. Therefore, understanding how to choose and utilize quality inks becomes paramount for companies in the food packaging industry.

The Importance of Compositional Compliance and Review

The packaging structure consists of multiple layers, each contributing to the safety and integrity of the food product within. The composition or individual substances in each layer need to be assessed according to their corresponding material regulations in the jurisdiction(s) of interest. This evaluation includes factors like maximum use limits, food or temperature restrictions, extractive limitations, and specific migration limits.

Among these layers, inks often garner significant attention due to their visible presence in the packaging “sandwich.” The quality of ink drops, therefore, becomes crucial to ensure that it does not negatively impact food, human health, or the environment.

Ink Quality and Safe Food Packaging

Ink quality plays an essential role in creating safe food packaging. High-quality inks are manufactured using safer ingredients than alternative technologies, producing superior, durable results needed to compete and differentiate in the competitive food packaging markets.

Migration Testing for Complete Package Safety

Once the individual material regulations are reviewed, the complete package must be assessed as a whole. This evaluation includes good manufacturing processes, organoleptic properties, and migration limits.

Migration testing is the cornerstone of packaging safety, proving that the package doesn’t release components into the food that could impact human health or alter the taste or odor of the product. The ink quality significantly influences the outcome of these tests, highlighting the critical role that ink drops play in the safety and compliance of food packaging.


Quality inks are more than just a component in the food packaging process. They are the silent sentinels ensuring the safety, compliance, and market competitiveness of food products. By understanding and acknowledging the role of high-quality ink drops in the label printing industry, businesses can guarantee not only the safety and regulatory compliance of their products but also their success in the highly competitive food and beverage market. The selection of high-quality, safe, and compliant inks, therefore, is not just a decision—it’s an investment in the brand, customer safety, and the future of the business.
