The little PLU sticker on fruit is regulated as an indirect food additive — both its facestock and its adhesive must comply with FDA food-contact regulations, because adhesive migrates into what it touches.
Most product labels never touch food — they sit on a package. But produce stickers, labels on unwrapped cheese wheels, and marks applied directly to edible goods are a different regulatory category: direct food contact. Getting this right is not optional for growers, packers, and food processors selling into the US market.
What 'direct food contact' actually means
The FDA regulates substances that touch food, including label components. When a label is applied directly to produce or food, both the facestock and — critically — the adhesive must be made of substances cleared for food contact. Adhesive compliance is the part buyers most often overlook: it's the layer actually touching the food, and standard label adhesives are not formulated or cleared for it.
This is why 'food-safe labels' from a general print shop deserve scrutiny. The right question for any supplier is specific: is this exact material-and-adhesive construction approved for direct contact with food?
When you need it — and when you don't
- Direct-contact stock required: PLU and branded stickers on fruits and vegetables, labels on unwrapped cheese or baked goods, any label touching edible product
- Standard packaging stock is fine: labels on sealed bags, boxes, bottles, and films where the label touches the package, not the food
- Gray areas — labels inside packaging, or on liners that touch food — deserve a conversation with your supplier and, when in doubt, the compliant construction
Practical notes for produce operations
Produce labeling adds mechanical demands on top of compliance: labels must apply at high speed onto curved, cool, sometimes damp surfaces, hold through the cold chain, and peel off cleanly in a kitchen. That's a narrow engineering window, which is why produce label constructions are purpose-built rather than adapted from general stock. GL Labels stocks FDA direct food-contact approved materials and converts them to applicator spec for pack houses — it's one of the industries we've served longest from Baja California's produce corridor.
