Food Packaging Has Rules
Unlike regular consumer goods, food cartons must meet safety standards. The ink can’t touch the food. The board can’t leach chemicals. The seal must show if someone tampered with it.
Here’s what matters.
Food-Safe Materials
Food-Safe Board
We use food-grade coated board that’s safe for indirect food contact. This means:
- No harmful chemicals in the board
- Suitable for food packaging
- Meets food contact regulations
Food-Safe Inks
Offset printing inks used for food cartons are formulated to be safe. No heavy metals, no toxic pigments.
Inner Liner
The inside of the box is blank or printed with food-safe ink. The product touches this surface.

Tamper-Evident Features
Food customers want assurance. Add:
Tear Strip
A perforated strip that must be broken to open the box. Shows if it’s been opened.
Safety Seal
A sticker or seal across the opening. Broken seal = tampered.
Perforated Top
Easy-tear top that can’t be resealed.
Window Boxes for Food
Windows let customers see the actual product — especially important for:
- Baked goods — Show the cookies or pastries
- Candy / chocolate — Show the confection
- Snacks — Show the product inside
- Deli / prepared foods — See the portion
Use food-safe PET film for the window.

Printing Considerations for Food
- Ingredients list — Must be printed, legible, accurate
- Nutrition facts — Required in most markets
- Barcode — Must be scannable
- Storage instructions — Keep dry, refrigerate, etc.
- Best before date — Usually stamped, not printed
Leave space on the carton for these mandatory elements.
Common Food Packaging Mistakes
- Wrong board grade — Non-food board for food product
- No tear strip — Customers can’t tell if it’s been opened
- No space for ingredients — Forced to stick labels on
- Window too large — Product falls out
- No inner liner — Direct contact with printed surface
