No bad chemistry
BPA-free. BPS-free. Leuco-dye-developer-free. The FreshDot substrate doesn’t use any of the bisphenol or leuco-dye chemistries that most direct-thermal labels rely on.
Better for food. Better for staff.
Label Performance
Built for the kitchen environment, not adapted from packaging
Most thermal labels in the food industry were originally designed for warehouse logistics and adapted to food use. The FreshDot label substrate was engineered for the kitchen from the start — chemical-free chemistry, freezer-grade temperature range, and food-contact compliance built in.
Three Things That Matter
What’s on a FreshDot label is not on most thermal labels
When labels sit on containers in a walk-in for four days, against the side of a Cambro full of stock, or in a freezer at sub-zero temperatures, the physical properties of the label become a food safety question. Three things about FreshDot’s substrate matter most.
Freezer-grade
Rated to -40°F. Performs reliably across refrigeration, freezer, and ambient kitchen environments without legibility loss or adhesive failure.
From walk-in to freezer to line.FDA food-contact compliant
Compliant with FDA 21 CFR food-contact substantiation. Designed for proximity to food and food-contact surfaces — not just for outer packaging.
Documentation available.
Chemistry
The chemicals that are in most thermal labels — and aren’t in ours
Direct-thermal labels rely on a coating that develops color when heat from the printer hits it. The chemistry most manufacturers use to make that work involves compounds that have raised regulatory and food-contact concerns.
Most thermal labels
Common direct-thermal chemistry
-
BPA (bisphenol A) Endocrine disruptor; restricted in many food-contact applications globally.
-
BPS (bisphenol S) Common BPA replacement with similar regulatory and toxicological concerns.
-
Leuco-dye developers Alternative thermal chemistry with its own set of food-contact and skin-contact questions.
FreshDot labels
Reveal-substrate chemistry
-
No BPA Substrate is manufactured without bisphenol A.
-
No BPS No bisphenol S used in the development chemistry.
-
No leuco-dye developers Color comes from the reveal-substrate technology, not from leuco-dye chemistry.
The reveal-substrate technology works on a fundamentally different physical principle than standard direct-thermal labels. Color is built into the substrate and revealed by heat from the print head — the printer doesn’t deposit a thermal-developer chemistry. The result is a label that produces a full color field with none of the chemistries used in most of the market.
Temperature Range
From the freezer to the prep line, without legibility loss
Most thermal label specs top out at standard refrigeration. FreshDot labels were engineered for the full operating range a real kitchen uses, including deep freezers and walk-in conditions where condensation, ice, and temperature cycling are routine.
−40°F
Lower operating threshold. Labels retain print legibility and substrate integrity at temperatures well below standard freezer storage, suitable for blast freezers, ice cream walk-ins, and long-term frozen product storage.
Ambient kitchen
Dry storage, prep line, garde manger station, room-temperature prep.
Walk-in refrigeration
Cold prep, dairy, produce, cooked-and-cooled product storage.
Standard freezer
Bulk frozen storage, batch-prep cooked items held for weeks.
Blast / deep freezer
Rapid cooling of just-cooked product, long-term frozen seafood and protein.
Regulatory
Food-contact compliant under FDA 21 CFR
Many thermal labels are adjacent to food — on the outside of a container, in proximity but not contact. FreshDot labels are designed for food-contact compliance, meaning they meet the FDA’s standards for materials that may touch food-contact surfaces.
FDA
21 CFR Compliant
Why this matters for food safety directors
A food-contact substantiation is what your QA team or health inspector will ask for if a label ever ends up where it shouldn’t — touching a hotel pan of cooked product, stuck to the inside of a bus tub, or in contact with portioned proteins. The right answer is documentation. FreshDot has it.

In Practice
What this means in your kitchen
Defensible documentation
BPA/BPS-free and FDA 21 CFR substantiation are the questions an auditor or inspector will ask. We provide the answers in writing.
One label for every storage condition
Same label on a hotel pan of cooked product, a Cambro in the walk-in, and a bag in the blast freezer. No separate label SKUs by storage location.
Safe to handle
BPA-free and BPS-free means no concern about cumulative dermal exposure for staff who handle dozens of labels per shift.
Consolidates SKU complexity
One label substrate covers refrigeration, freezer, and ambient storage. Fewer SKUs, one supplier, one contract.
