How to Store Stickers: Keeping Sheets and Rolls Usable

The box of company stickers spent a year in the back of the company van. Now it's needed. The backing paper has gone wavy, the sheets no longer lie flat, and nobody knows whether the adhesive still holds the way it did on day one.

How you store stickers until they are needed decides their condition long before the first one goes on. Backing paper behaves like printer paper from a damp cellar: paper reacts to the air around it.

The values in this article come from the processing guidelines and data sheets of vinyl manufacturers. The sources are listed at the end of the article.

Why it matters how stickers are stored

Manufacturers give a shelf life for their material and state the conditions that go with it: temperature, humidity, packaging. The shelf life applies to those conditions. If the goods are stored differently, you can no longer rely on it.

One distinction first. Shelf life applies to unapplied goods in the box. How long a sticker lasts once it is applied is a separate value and has little to do with storage. What matters in use is covered in Stickers Must Meet Specific Requirements.

How to store stickers: temperature, humidity, light

Temperature and humidity

Stickers are best kept at normal room temperature. Summarised from several data sheets, that means roughly 18 to 25 °C at 40 to 55 % relative humidity. The individual figures are narrower, for example 18 to 22 °C at 40 to 50 %, or 19 to 25 °C at 45 to 55 %.

The climate should also stay constant, day and night. Strong cooling encourages the edges of sheets to curl. An unheated room with cold nights is therefore the wrong place for sheet stock.

Light, heating and dust

No direct sun, no spot next to the radiator. The processing guidelines expressly advise against both. That rules out the office windowsill, however handy the box may be there.

Then there is dust. Unapplied vinyl should be kept as dust-free as possible, meaning in a closed box or a cupboard and not open on a shelf.

Cut vinyl lettering that already comes with application tape belongs in the dark. UV light can bond the application tape so firmly to the sticker that it is hard to remove later.

The values at a glance, depending on the product:

• Ideal (summarised from several data sheets): about 18 to 25 °C and 40 to 55 % humidity, as constant as possible
• Limit (one manufacturer): clean and dry, below 38 °C and below 80 % humidity
• Place: clean and low in dust, out of direct sun, not next to radiators

Flat or rolled?

In short: sheets flat, rolls supported, and both in the original packaging for as long as possible.

Sheets and single stickers: flat

Sheets belong lying flat on the shelf, in their original packaging. Don't stack them printed side to printed side, and don't put anything heavy on top.

Once a pack of sheets has been opened, wrap the rest up tightly again. Polyethylene film sealed with adhesive tape is recommended, so that the backing paper doesn't absorb moisture. In everyday use, a resealable bag will do.

Why sheets curl: Usually it's the backing paper. It absorbs moisture or changes its dimensions when the air is too dry or too humid. Then the sheet no longer lies flat, and the cutting dimensions can shift.

Rolls: never just lay them down

Manufacturers are stricter about rolls. Their rules apply to wide vinyl rolls: such a roll never rests unsupported on its curved side. The manufacturers name three ways to store them:

• in the original box, with end caps and in the original wrapping
• hanging horizontally, on a rod through the core
• upright on roll supports

This also applies to opened vinyl rolls. If you take one out of the box, hang it up or stand it upright on roll supports.

Our sources give no separate rules for label rolls. Our advice: leave them in the box, supported, and don't lay them loose on their curve.

Store printed, finished-cut stickers flat. If large digitally printed stickers have to be rolled, roll them loosely with the design facing outwards, on a core at least 15 cm in diameter. This does not apply to label rolls. The aim is to stop the stickers or application tape coming away from the backing paper.

How long can stickers be stored?

Printed stickers are best applied within one year of printing. That is what one vinyl manufacturer recommends. According to data sheets, unprinted vinyl can usually be stored for around two years from manufacture, one to three years depending on the product, in each case under the storage conditions above.

The vinyl's shelf life counts from manufacture, not from purchase. But you can't tell the manufacturing date by looking at the sticker. So note down the print or delivery date. The period from printing is your practical guide.

According to the data sheet, promotional stickers with a short-term removable adhesive can be stored unprocessed for around one year. They are made for the promotion, not for the drawer.

With paper labels, humidity comes into play as well. Paper is meant for dry interiors; vinyl labels cope better with moisture. Paper absorbs moisture, as the backing paper of most stickers already shows. Paper labels therefore have even less business in damp rooms.

Our rule of thumb: only order as much as will be applied within one year of printing.

Storing stickers at home

At home, stickers usually live in a drawer. That's a reasonable place, as long as the drawer isn't directly above the radiator. Sticker sheets stay flat, in a folder or a flat box, and are not rolled up in the pencil pot.

The same values apply at home as in a business. A cupboard in a living room is fine, the sunny windowsill in a child's bedroom is not.

Opened packs of sheets go back into their packaging. The same applies to a collection.

Storing labels and stickers at work

In a business, the stock is often kept where it's used: in the company van, in the workshop, in an unheated storeroom. That's convenient for the workflow, less so for the material. Behind the windscreen the sun beats down in summer, and in winter the van cools down overnight. Such a place hardly meets the manufacturers' constant ideal range.

Our advice: the stock belongs in a heated room, such as the office. Only what will be applied soon goes in the van.

• Keep the original packaging: box closed, packs of sheets sealed tight, rolls in the box or hung up.
• Labelling: print or delivery date and contents written on the outside of the box.
• Order of use: use up older stock first.
• Cut vinyl lettering: store in the dark with its application tape.

Large stocks are often unnecessary. We also print stickers in very small runs, from a single piece. Then less sits in the box, and the one-year period becomes an issue less often.

Before use: acclimatise and do a test

Stickers stored in the cold should take on the temperature and humidity of the work room before they are processed. So let the box acclimatise in the room first, then unpack it.

How long that takes depends on the quantity and the temperature difference. According to one manufacturer, stacks of sheets need this long:

• 250 sheets: 3 hours at a 5 °C difference, 6 hours at 10 °C, 10 hours at 15 °C
• 1,500 sheets: 4, 9 and 15 hours at the same differences

We found no comparably documented time for rolls. Our recommendation: go by the sheet times above, and if the temperature difference is large, leave the goods in the room overnight if in doubt. The box still doesn't belong on the radiator.

Then the test. The processing guidelines generally advise a trial application before final application and assessing the final adhesion after 24 hours. With older stock we strongly recommend it: apply one piece to an inconspicuous spot on the real surface and check it the next day. The test shows whether the goods still have initial adhesion. It does not show whether they will last. If even the test holds poorly, reorder before the whole series goes on.

The box in the unheated storeroom

A typical scenario: a trade business has a larger quantity of company stickers printed so it doesn't have to reorder for a while. The box goes into the unheated storeroom.

After one summer and one winter, the sheets may curl at the edges. Whether the stickers still adhere is only shown by a test, and even then only for initial adhesion.

The better way: store the stock in the office, flat and in its original packaging, with the print or delivery date on the box. Order smaller quantities more often. And before the next use, let the goods acclimatise in the room and do a test.

Smaller quantities, more often

If you ask us how much belongs in stock: the best stock is the stock that doesn't sit around for long.

A sticker has two clocks. The first runs in the box, from the day the vinyl was made. The second starts when it is applied. Stockpiling too much wastes time on the first clock.

A climate-controlled room isn't necessary for a small business or a sticker collection. A cupboard in a heated room out of direct sun is a good place. If you want to know exactly, put a hygrometer in with it.

Which vinyl suits which period of use can be found under Foil Technology.

Conclusion: the stock belongs in the office, not in the van

Stickers are best stored at room temperature, out of the sun and away from heating, with sheets flat and rolls supported. Printed stickers are best applied within one year of printing. Ask your stock three questions. Where is it, in a heated room or in the van and the cold storeroom? Since when has it been there, and is there a date on the box? And will the quantity be applied within one year?

Frequently asked questions

How long can stickers be stored?

Printed stickers are best applied within one year of printing. That is what one vinyl manufacturer recommends. According to data sheets, unprinted vinyl can usually be stored for around two years from manufacture, one to three years depending on the product, at a constant temperature of about 18 to 25 °C and 40 to 55 % humidity. Write the print or delivery date on the box.

At what temperature should stickers be stored?

Ideally at normal room temperature. Summarised from several data sheets, that means about 18 to 25 °C at 40 to 55 % humidity, as constant as possible. As an outer limit, one manufacturer gives below 38 °C and below 80 % humidity. Also store stickers somewhere clean, out of direct sun and not next to the heating.

Can I still use old stickers?

Often yes, but check first. Let goods stored in the cold acclimatise in the room, then apply one piece to an inconspicuous spot on the real surface and check it the next day. That shows the initial adhesion, not the durability. If printed goods are more than a year old, check especially carefully. If even the test holds poorly, reorder.
