Store unused direct thermal labels in a clean, dry, cool, dark indoor location, protected in their original packaging until needed. Keep them separate from heat, direct sunlight, chemicals and cleaning products. Follow the storage instructions for the exact label material, use the oldest viable stock first, and check a sample before returning an opened or questionable pack to your dispatch bench.
This guide covers blank label stock before printing. The storage life of unused labels and the useful life of a printed shipping label are different questions. Neither has one universal answer for every direct thermal product.
Why direct thermal label storage matters
Direct thermal printing forms an image through a heat-sensitive label surface. Heat exposure can therefore affect the media before it reaches the printer. Label selection also depends on the conditions the finished label will face and how long its information needs to remain readable, as explained in Brother Australia's guide to label media and printing methods.
Good storage does not turn ordinary shipping stock into an outdoor or long-term identification label. Treat storage, printer fit and intended use as separate checks. For purchasing, start with the thermal shipping label collection and read the information for the exact format you need.
Choose a storage location before opening the carton
Zebra's media storage guidelines recommend a clean, dry, cool, dark area, protective packaging and separation from chemicals. Apply that general guidance alongside your supplier's material-specific instructions.
For a small packing operation, walk through the actual stock area rather than judging it only when the delivery arrives. Look for changes during the working day: sunlight reaching a shelf, nearby equipment running warm, cleaning supplies being moved beside stock, or packaging being left open between shifts.
- Choose a dedicated indoor shelf or cupboard where the media and its packaging stay clean and dry.
- Keep stock out of direct sunlight and away from heaters or other heat sources.
- Store cleaning products and chemicals elsewhere.
- Keep each label format identifiable without exposing every pack for inspection.
A shelf location is a working choice, not evidence of a particular temperature or humidity range. If the product documentation specifies limits, use those limits and the appropriate measurement method.
Keep reserve stock protected
Leave unused reserve packs in their protective packaging until they are needed. Retain the supplier label, product code and any batch or storage information. Once a pack is opened, keep the remaining media protected and identifiable when it is returned to storage.
Separate reserve stock from the quantity currently feeding the printer. This makes it easier to know which pack is open and which cartons are still untouched. Do not combine loose labels from unidentified packs merely because they look similar.
Label rolls
Keep the roll and its identification together. When moving it between storage and the printer, handle it so the edges, backing and outer labels can be inspected before loading. Follow the printer and media instructions for positioning and feeding the roll.
Fanfold labels
Retain the protective carton or wrapping and keep the stack organised in its supplied sequence. Before feeding it, check the folds and exposed labels for visible problems. The storage check does not establish whether the stack fits your printer or external feed arrangement.
If size terminology is the uncertainty, use the separate 4 x 6, A6 and 100 x 150 label-size explanation. A familiar size name is not a storage specification.
Use a simple stock record
Create a short record on the outer carton or in your stock sheet. The purpose is to identify the pack and its history, not to invent an expiry date. Record only what you know, and leave unknown details clearly marked for checking.
| Record | What to enter | Why it helps |
|---|---|---|
| Product identity | Supplier and exact product code or description | Find the correct material information |
| Format | Roll or fanfold and the stated label size | Keep different supplies separate |
| Received and opened | The dates your team actually recorded | Identify open packs and stock order |
| Batch and expiry | Supplier details if supplied | Follow documented limits rather than guess |
| Storage concern | Known exposure or visible problem | Hold uncertain media for checking |
Rotate the oldest viable stock first. A pack with an unresolved condition problem should not be used simply because it arrived first. Keep it separate while you check the supplier's guidance.
How long can unused thermal labels be stored?
Check the exact product documentation or ask the supplier. A statement about one manufacturer's paper, coating or adhesive cannot establish the storage life of a different label. The purchase date also does not necessarily identify the manufacturing date.
Useful questions are: does this product have a stated shelf life or expiry, what conditions apply, what date does the period start from, and is there separate advice for opened stock? Keep the answer with the product record. Without that information, do not assign a generic number of months or years to the pack.
Check an opened pack before dispatch use
Use a repeatable inspection rather than relying only on whether the first label prints. A simple internal checklist can separate issues you can see from information that still needs supplier or printer guidance.
- Confirm identity. Match the pack to the intended label format and the documentation for your printer.
- Inspect the blank media. Look for unexpected darkening, marks, damp packaging, damaged edges or labels lifting from the backing.
- Review its history. Check any recorded heat, sunlight or other storage exposure.
- Print a sample. Use your normal documented settings and inspect the text and barcode.
- Check the intended task. Confirm the sample meets your dispatch process and relevant carrier requirements before using the pack for orders.
A sample is a practical screening step. It does not prove future readability, long-term adhesion or suitability for every surface and environment. If something looks wrong, hold the pack and investigate rather than changing several printer settings to disguise the issue.
Handle questionable stock separately
If packaging is damaged, the media has changed appearance, or the storage history is unclear, label the pack as awaiting a check. Record the concern and keep the original product identification available. Contact the supplier with the product and batch information, the observed issue and the conditions you know about.
Do not assume every blank print or poor feed is caused by storage. Media type, loading, printer settings and hardware condition can also need investigation. Follow the manual for the exact printer, and keep a media inspection separate from any repair decision.
Fit storage into the packing-station routine
Give one location to reserve label stock and one clearly identified position to the open working pack. At the end of a shift, record unresolved concerns and return unused supplies to their protected storage location. The next person should be able to identify the media without guessing.
The broader small ecommerce packing-station checklist covers the workspace and dispatch workflow. Keep this label-specific routine alongside it, with product records accessible to the team.
Common storage questions
Can I leave spare labels beside the printer?
Check that location against the actual storage instructions. Convenience alone does not establish that it is suitable. Keep reserve stock protected and assess heat, sunlight, cleanliness and nearby chemicals.
Can labels be stored in a vehicle?
A vehicle is not a substitute for the recommended indoor storage conditions. Check the exact material instructions and any known exposure before using stock that has been left there.
Does protective wrapping guarantee the labels are still usable?
No. Packaging is one part of the storage process. Product identity, stated limits, known conditions and a pre-use check still matter.
Should I refrigerate labels to keep them longer?
Do not replace the supplier's storage instructions with an improvised refrigeration routine. Ask for guidance for the exact material if your storage area cannot meet its requirements.
