Elements of Color Changing Stickers

Ultraviolet light

  • One of these elements is the light from the sun.
  • Such stickers have the name photo stickers.
  • For these stickers, they remain normal and activation only occurs when they gain exposure to sunlight.

Temperature Change

  • It is possible because they comprise of color-changing liquid crystals also known as TLC.
  • These crystals have colors that change when they are first heated
  • After heating the crystals are cooled



  • The components of TLC’s in color changing stickers have twists.
  • Such elements comprise a mixture of different active organisms. TLC pass through the light color spectrum during their healing process. These colors disappear when the crystals cool, and their disappearance is in reverse order.request quote from zigpac
  • Ultraviolet light also activates the color-changing decals.

Exposure to light and heat

  • Exposing your stickers to both sunlight and high temperatures cause components to break
  • These temperature-sensitive stickers have a shelf life of about a year or more if stored properly.
  • Constant changes in temperature will cause the stickers to keep changing their colors, thereby making them weaker.

Knowing When They Degrade

  • It is quite easy to know when your sticker is losing its spark.
  • First, the stickers tend to dim

The Best Way to Store Your Heat Temperature Sensitive Color-Changing Sticker

Heat temperature-sensitive color changing stickers have become very popular in today’s market. Here is the best way to ensure the durability of your thermochromic stickers:

Storage, Validity, and Packaging

  • The thermochromic pigments used in making these stickers are not very good at light-fastness. Whenever these stickers are exposed to the sun, the ink starts to fade and become unavailing. Hence, it is better to use these stickers indoors, than to use them outdoors. Therefore, in order to preserve the life of the sticker, avoid exposing it to strong sunlight and also ultraviolet light.
  • For these heat-sensitive materials, the color state’s heating stable property is far better than the discolor state. Additionally, if the temperature exceeds 80 degrees, the organic matter’s discoloration will start degrading. So, you should avoid storing the color pigments long-term over 75 degrees.
  • These stickers should be stored and packaged with normal storage circumstances and are to be valid for 12 months.


  • Test a sample of the sticker first before embarking on mass production.
  • The heat sensitive color changing stickers should be packaged properly and sealed. Be sure to keep the stickers in a dry place. Do not store them in a wet place or somewhere that has a high temperature.

How to Make Color Changing Stickers Using Heat Sensitive Powder

Making these color changing stickers with heat-sensitive powder is really easy. Once you get the materials needed, you will have your stickers in a couple of minutes.

Materials Needed

  • Temperature-sensitive powder (you can find it easily on science-related websites)
  • Adhesive paper
  • Pencil
  • Eraserrequest quote from zigpac
  • Thin permanent marker
  • Fill pencil markers
  • A small disposal cup
  • Acrylic paint
  • Small stick (like a toothpick)
  • Small paintbrush
  • Clear (transparent) tape
  • Scissors
  • Some water



  • Get an adhesive paper. Draw a sketch of the images or characters you intend to turn into a heat-sensitive color changing sticker on it.
  • Redraw the lines on the sketch with a thin permanent marker.
  • Erase the pencil lines with an eraser.
  • Decide on the part of the image to change color.
  • Use different colors of fill pencil markers to paint different parts of the image or character. These parts should be places you do not want to be affected by the change in color. You can use more than one color of pencil marker for different parts.

  • Get a small disposable plastic cup and mix the powder with any color of acrylic paint you want in it. Start by placing a little of the acrylic paint in the cup, then stir well with a small stick. Then add some of the temperature-sensitive powder to the paint, and use the same stick to stir the mixture properly.
  • Stir in a few drops of water to reduce the thickness of the mixture.
  • Use a small paintbrush to apply the mixture to the parts of the image that you want to change color. Do this neatly and carefully so it does not touch the other parts of the image. Apply as many different colors as you need to make it opaque, then allow it to dry completely.
  • Place the clear tape on top of the character or any design. Then cut them out with a pair of scissors. When cutting, you can decide to leave a little bit of paper around the images or just trim the excess.
  • You can place your palm over them for some time to test whether they are sensitive to heat. If they change color when you take off your palm, it means success.request quote from zigpac
