Food-Safe Packaging: Materials, Inks and Barriers Explained
Food packaging clears a higher bar than ordinary boxes, because it touches what people eat. That means food-grade materials, food-contact-safe inks, and the right barrier for the product. This article goes deeper on food safety than our main food packaging guide.
What makes packaging food-safe?
Food-safe packaging uses materials and inks that are approved for contact with food and will not transfer harmful substances into it. In the US, the FDA regulates food-contact substances, and compliant packaging uses food-grade stocks with low-migration, food-contact-safe inks. There is a difference between direct contact (the food touches the box) and indirect contact (a wrapper or inner bag sits between), and it affects which materials you need.
Food-grade materials
- Food-grade SBS cardstock – bright, smooth, and common for retail food cartons.
- Kraft – a natural, recyclable choice for bakery and artisan food.
- Corrugated – strength for shipping and heavier items; see corrugated boxes.
Grease and moisture barriers
The barrier has to match the food. Oily and fried items need grease resistance; wet or refrigerated items need a moisture barrier. These coatings keep the box clean and structurally sound, so a takeout carton does not soak through and a bakery box holds its shape.
The PFAS-free shift
Grease resistance was traditionally achieved with PFAS chemistries, but the FDA and a growing number of states are phasing PFAS out of food packaging. The current best practice is PFAS-free grease-resistant options, so ask for them when your product needs a grease barrier – it keeps you ahead of changing rules.

Frequently asked questions
Are your food boxes safe for direct food contact?
Yes. We print on FDA-compliant, food-grade stocks with food-contact-safe inks, and add grease or moisture barriers for items that need them.
Can I get grease-resistant boxes without PFAS?
Yes. PFAS-free grease-resistant options are available, which keeps your packaging ahead of tightening FDA and state rules.
Do printed inks touch the food?
We print with food-contact-safe, low-migration inks, and for many products the print is on the outer surface. We will recommend the right setup for direct-contact uses.
