The adhesive on a thermal label is just as important as the paper, and different jobs need different adhesives. Shipping labels want a strong permanent bond, while other uses benefit from a removable adhesive that peels cleanly. Choosing the wrong one means labels that fall off in transit, or that damage what they were stuck to.
Permanent adhesive: the shipping default
Permanent adhesive is the standard for shipping labels because it bonds firmly to cardboard, poly mailers and most packaging, and resists peeling during transit. For a parcel that passes through sorting machines and handling, a permanent adhesive is what keeps the label attached from dispatch to delivery, which our permanent vs removable guide covers in depth.
Removable adhesive: clean removal
Removable adhesive holds a label in place but peels off cleanly without residue or damage, which matters for labels on products, shelf edges or packaging the customer will keep. It's the wrong choice for shipping, where the label needs to survive rough handling, but right for any label that should come off easily later.
Freezer and cold-temperature adhesives
Standard adhesives can fail in cold conditions, which is why freezer-grade labels exist for cold-chain and frozen goods. If you ship anything refrigerated or frozen, a freezer-grade adhesive is essential, because a standard label will lift and fall off as the packaging condenses and flexes in the cold.
High-tack and textured-surface adhesives
Some packaging surfaces, like recycled cardboard, fabric mailers or slightly textured boxes, defeat standard adhesives. High-tack adhesives are formulated to grip these harder surfaces. If you've had labels fall off a particular type of packaging, the fix is usually a higher-tack adhesive rather than more tape.
Matching adhesive to your packaging
The reliable rule is to match the adhesive to the surface and conditions. Corrugated cardboard, poly mailers, cold storage and reusable packaging each suit a different adhesive. Testing a new label stock on your actual packaging before committing to a full order prevents the discovery that labels don't stick halfway through a dispatch run.
Why the label surface matters too
Direct thermal labels need a clean, dry, flat surface to bond properly, and even the best adhesive fails on a dusty, damp or curved surface. Wiping the surface and applying the label flat, avoiding seams and tape, gives the adhesive its best chance, the same care our barcode guide recommends for scannability.
Choosing the right label for your operation
For most e-commerce, a strong permanent adhesive is all you need. Add freezer-grade only if you ship cold goods, and removable only for labels that must peel cleanly. Keeping a single well-chosen stock for shipping, rather than a shelf of options, is the simplest way to avoid adhesive failures.
Frequently asked questions
What adhesive should shipping labels use? Permanent adhesive, because it bonds firmly to packaging and resists peeling through sorting and handling.
Do I need freezer-grade labels? Only if you ship refrigerated or frozen goods, where standard adhesives can fail in the cold.
Why are my labels falling off cardboard? The adhesive may not match a textured surface. A high-tack adhesive, plus a clean dry flat surface, usually fixes it.
Labels that stay put
Our 100 × 150mm direct thermal labels use a permanent adhesive built for cardboard, poly mailers and the rough handling of real shipping.
