How to make print stickers odorless?

Jul 29, 2025

As a print sticker supplier, I've encountered numerous customers expressing concerns about the unpleasant odors often associated with printed stickers. In the modern market, where consumers are increasingly conscious of environmental and health - related factors, the demand for odorless print stickers has been on the rise. In this blog, I'll share some effective strategies on how to make print stickers odorless.

Understanding the Sources of Odor in Print Stickers

Before we delve into the solutions, it's crucial to understand where the odors in print stickers come from. The main sources typically include the inks used for printing, the adhesive on the stickers, and the base material of the sticker itself.

Inks

Most traditional inks contain volatile organic compounds (VOCs). These are chemicals that can easily evaporate at room temperature, releasing unpleasant and potentially harmful fumes. Solvent - based inks, in particular, are notorious for their strong odors because they rely on solvents to keep the ink fluid during the printing process. When the solvents evaporate, they leave behind an odor that can linger for a long time.

Adhesives

Adhesives are another significant source of odor. Some adhesives are formulated with chemicals that emit a strong smell, especially when they are freshly applied or when they are exposed to heat or humidity. The curing process of adhesives can also release odorous by - products.

Base Materials

The base materials of stickers, such as plastics and papers, can also contribute to the odor. Some plastics may have a natural odor, and if they are not properly treated or manufactured, this odor can be even more pronounced. Additionally, if the base material has been stored in a damp or poorly ventilated environment, it may develop a musty smell.

Strategies to Make Print Stickers Odorless

Choose Low - VOC or VOC - Free Inks

One of the most effective ways to reduce odor in print stickers is to switch to low - VOC or VOC - free inks. Water - based inks are a popular choice in this regard. They use water as the main solvent instead of traditional organic solvents, which significantly reduces the emission of VOCs. Water - based inks are not only more environmentally friendly but also produce stickers with little to no odor.

UV - curable inks are another option. These inks are cured using ultraviolet light, which means they don't rely on solvent evaporation for drying. As a result, they don't release the same amount of odorous fumes as solvent - based inks. UV - curable inks also offer excellent durability and colorfastness, making them a great choice for high - quality print stickers.

Select Odorless Adhesives

When it comes to adhesives, there are several odorless options available in the market. Silicone - based adhesives are known for their low odor and high performance. They offer strong adhesion and are resistant to heat, moisture, and chemicals. Another option is acrylic - based adhesives, which can also be formulated to be odorless. These adhesives are versatile and can be used on a variety of base materials.

Before using an adhesive, it's important to test it for odor. You can do this by applying a small amount of the adhesive on a sample sticker and letting it dry in a well - ventilated area. If there is still a noticeable odor after the adhesive has fully cured, it may not be the best choice for odorless stickers.

Opt for High - Quality Base Materials

The quality of the base material can have a significant impact on the odor of the sticker. Choose plastics and papers that are specifically designed to be odorless. For example, some PVC films are treated to reduce their natural odor. Additionally, make sure that the base materials are stored in a clean, dry, and well - ventilated environment to prevent the development of musty smells.

Post - Printing Treatment

Even after using low - odor inks, adhesives, and base materials, there may still be a slight residual odor. Post - printing treatments can help to further reduce or eliminate this odor.

Ventilation

Proper ventilation is essential during the printing and production process. Make sure that the printing area is well - ventilated to allow any odorous fumes to escape. After the stickers are printed, they can be placed in a well - ventilated area for a period of time to allow the remaining odors to dissipate.

Baking or Drying

In some cases, a gentle baking or drying process can help to remove residual odors. However, it's important to be careful not to overheat the stickers, as this can damage the inks, adhesives, or base materials. The ideal temperature and duration of the baking or drying process will depend on the specific materials used in the stickers.

Odor - Absorbing Agents

Using odor - absorbing agents can also be an effective way to reduce odor. For example, activated carbon can be placed near the printed stickers to absorb any remaining odorous molecules. Some natural substances, such as baking soda, can also be used for this purpose.

Quality Control

Implementing a strict quality control system is crucial to ensure that the print stickers are truly odorless. At our company, we have a multi - step quality control process.

Die Cut Stickers

First, we conduct a pre - production odor test on all the raw materials, including inks, adhesives, and base materials. Only materials that meet our odor standards are used in the production process.

During the production process, we regularly monitor the odor of the stickers. We have trained personnel who can detect even the slightest odor and take immediate action if necessary.

After the stickers are printed, we conduct a final odor test before they are packaged and shipped to the customers. This ensures that every sticker that leaves our facility is odorless.

Conclusion

Making print stickers odorless is a multi - faceted process that involves choosing the right materials, implementing proper production techniques, and conducting strict quality control.
