Inks and Coatings Designed for Low Migration Packaging

Sun Chemical is a market leader in the development and promotion of inks and coatings designed for low migration sensitive packaging applications such as food, pharmaceutical, personal care and tobacco.

What is Low Migration?

The term “low migration” packaging is commonly used to designate materials used in the packaging structure whose chemicals will not migrate, or move, from the packaging into the product.

To qualify as low migration packaging, these materials contained in the packaging structure, including printing inks, coatings and adhesives, must not have any migratory chemicals which would affect the appearance, flavor, odor, taste, or the safety of the product contained within the packaging.

Sun Chemical’s Solutions to Low Migration

SunPak Intertech AwardWe continue to invest in R&D, new technology, product stewardship and regulatory compliance with sensitive packaging requirements.  We work hard to take the lead in educating all partners in the supply chain, from the raw material supplier to the graphic designer to the printer converter through to the brand owner and retailer about compliance, the potential pitfalls, their options, as well as opportunities.

Sun Chemical has for many years worked on understanding the factors affecting migration and has developed a complete portfolio of inks and coatings for low migration sensitive packaging to support the packaging chain across a range of print processes and technologies.

Sun Chemical’s official best practice guide to low migration printing was an industry first in providing practical guidance.
