Principal display panel: what belongs on the front of a US food pack
The principal display panel (PDP) is the front — the face shoppers see first. FDA expects the statement of identity and the net quantity of contents there. It is not the place to dump the full ingredients list, and it is not a free-for-all of health claims.

The short answer
The principal display panel (PDP) is the front — the face shoppers see first. FDA expects the statement of identity and the net quantity of contents there. It is not the place to dump the full ingredients list, and it is not a free-for-all of health claims.
Where this shows up in a real kitchen
Direct-to-consumer brands design pouches like posters. The product name is a joke, the weight is on the back in 6-point type, and the front is a lifestyle photograph. That layout fails the PDP rules even if the ingredients on the back are perfect.
The US rule
21 CFR 101.1 and 101.3 plus 101.105 put identity and net quantity on the PDP. Identity is the common or usual name, in a type size related to the most prominent printed matter. Net quantity sits in the bottom 30 percent of the PDP, generally parallel to the base. FDA’s Food Labeling Guide illustrates placement.
How to apply it
Pick the panel a customer sees at retail or in a product photo. Put “Peanut butter cookies” not “Sunday Funday”. Put “8 oz (227 g)” in the lower third. Claims on the front must still be truthful and not conflict with Nutrition Facts. Allergen Contains lines still belong with the ingredients, usually on the information panel.
- Identify the true front of the pack, including e-commerce hero images.
- Write a common-name identity, not a campaign slogan.
- Place net quantity in the lower 30 percent in allowed units.
- Keep ingredients, allergens and Nutrition Facts for the information panel unless a small pack combines them legally.
Worked example
A stand-up pouch of trail mix photographed for Amazon: the front says “Mountain trail mix” and “10 oz (283 g)” in the bottom band. Almonds and peanuts are visible in the window — they still must be named on the information panel. A front badge “protein packed” needs a Nutrition Facts backing; it is not a PDP substitute for identity.
Checks that belong on this pack
| Check | Why it matters |
|---|---|
| Identity is readable as a food name | Shoppers and FDA both need to know what the product is. |
| Net quantity is on the front, not only in the Amazon bullet list | Website copy is not the PDP. |
| Type size of identity holds its own against the logo | A 6-point name under a 3-inch logo is not prominent. |
| Front claims do not contradict Nutrition Facts | “No sugar” on the front with added sugars on the back is a fight you lose. |
Hiding the weight on the back because the front is “cleaner”
Minimalist design is not an exemption from 101.105. Net quantity belongs on the PDP.
What LabelClear can and cannot print
Get the name of the food right — that part travels well from UK PPDS practice. Then add US net quantity on the front. The generator will not place PDP type for you.
Questions
Can the PDP be two faces of a box?
Do stickers on a glass jar count?
Is the Amazon title the PDP?
