Glow in the dark stickers are products that we see frequently. By explaining the working principles, influencing factors,suitable applications and their target audiences, the article will give a comprehensive understanding of glow stickers to you and facilitate your bulk ordering.
Main Materials Needed to Make a Sticker
Sticker base substrate
The substrate serves as the foundation for the stickers’ overall structure and determines their durability. Coated paper is suitable for low-cost, temporary indoor use; Vinyl (one type of PVC) is flexible and waterproof, making it fit for most applications;PET is resistant to sunlight, which is suitable for outdoor use and industry.
Selecting the right substrate will ensure the stickers fit for various scenes in daily life.
Luminous powder
This is the core material for luminous stickers,which determines whether or not they glow. This material appears bright white color.
The two main types are strontium aluminate luminous powder and zinc sulfide luminous powder.Strontium aluminate offers superior brightness and longer-lasting luminescence.Zinc sulfide is suited for basic indoor applications, providing a higher cost-effectiveness.
Adhesive and release paper
The adhesive backing and release paper are also components to ensure the users’ experience about luminous stickers. High-quality release paper peels away smoothly, while a superior adhesive backing ensures a stable bond without damaging the stickers.
If choosing the correct adhesive and release paper,they can minimize issues such as application failures and adhesion during storage.These can help you guarantee product quality and reduce after-sales requirements.
How Do Glow in the Dark Stickers Work?(Photoluminescence Explained)
The principle of glow in the dark stickers is “photoluminescence”,involving light absorption, storage, and emission. The luminous powder within the stickers absorbs energy from sunlight (requiring 15–30 minutes) or indoor light (20–30 minutes) and stores it. When the surrounding environment darkens, the energy will gradually be released, resulting in a sustained glow.
The entire process requires no external batteries or electricity, making the stickers convenient to use.
The Factors that Affect the Performance
Material Quality
This is the most important influencing factor.As a wholesaler, if you want to avoid product failures or returns,you should select the appropriate materials.High-purity strontium aluminate has higher absorption efficiency and high brightness.Strontium aluminate stickers can typically glow for 6 to 12 hours.Inferior raw materials will degrade within a few months,leading to customers’ complaints.
Ambient Humidity
Humid environments will reduce the performance of the stickers.If your customers work outdoors or work in humid environments,you can apply waterproof layers and weather-resistant coatings to cope with this problem.
UV-Resistance Capability
Long-term exposure to sunlight may affect the performance of strontium aluminate, which may cause a rapid decrease of brightness until it turns yellow or even cracks.To resolve this, wholesalers should select products with UV-resistance coatings. This will block UV rays and preserve pigment performance to ensure long-term reliability in the open air.
Printing of Stickers
Printing method
There are four main printing methods:
- Full-color digital printing is ideal for small quantities wholesale and personalized customization.
- Offset printing offers stable color reproduction and lower costs, which make it suitable for bulk orders and industrial applications.
- Flexography enables roll-to-roll mass production and is suited for industrial orders.
- Screen printing can produce the brightest glow effects,which is an excellent choice for branding and logos.
Ink
Ink enables stickers to display a range of color effects and patterns. The use of eco-certified inks not only suits various printing processes,but also helps avoid customs clearance problems. It can also enhance the products’ competitiveness in the global market.
The commonly used international environmental certifications about inks include:
- REACH (EU Chemicals Regulation Certification,which is required to enter the European market);
- CPSIA (required to enter the U.S. market).
Coatings
The coating is also a component of luminous stickers. Selecting the right coating not only extends the products’ lifespan, but also meets the specific needs of diverse clients.There are four types of coatings:
- UV coatings offer resistance to scratching and weathering.
- Water-based coatings are eco-friendly and safe, making them ideal for indoor use.
- Glossy finishes enhance color vibrancy for an eye-catching look.
- Matte finishes enhance the texture.
The Application of Glow in the Dark Stickers
Luminous stickers function by absorbing and releasing light energy,rather than through chemical or nuclear reactions.They are safe, eco-friendly, odorless, and non-toxic.
- Public places requiring emergency exit signs and directional signage,such as hospitals, construction sites, shopping malls and transportation stations.Theaters can also use glow in the dark stickers to create seat markers, making it easy for customers to find their seats even in dark environments.
- Brands that want to highlight their business logo or serve them as promotional gifts.
- Outdoor indicator and safety signage.
- When spending festivals or events such as music festivals or night parades,the stickers can help enhance the atmosphere.
- Anywhere in the home,such as the bottle,mobile phone,computer or even the ceiling.
How to Choose a Reliable Glow in the Dark Sticker Supplier?
Firstly, you must focus on the quality of the materials,which determines the performance of the glow stickers. Secondly, you should verify whether the supplier holds the certifications and offers flexibility about Minimum Order Quantities (MOQ). It is essential to ascertain whether the supplier of the glow stickers is capable of delivering on time.
FAQ
What’s the service life of glow in the dark stickers?
Service life is determined by the raw materials and the operating environment:High-quality strontium aluminate stickers will not show significant brightness decay even after 5 to 10 years.It remains stable for many years of use indoors. When used outdoors,it requires the use of a high-quality PET substrate and premium luminous powder.
How should glow in the dark stickers be properly stored?
It is recommended to store luminous stickers flatly and avoid folding hard. If the stickers are only slightly folded or the surfaces are lightly scratched,they can still be used normally. However, if the stickers are severely cracked, their luminous performance will be significantly diminished.
What should be noted when using outdoors?
Choose glow in the dark stickers with protective coatings and pay attention to the waterproof and UV-resistance performance.
When placed outdoors,ensure sufficient exposure to light every day to guarantee nighttime brightness and sustainability.
To prevent dust and rain from affecting light absorption and luminescence, please wipe the surface regularly and keep it dry.Avoid irritating cleaning agents.
What can be done to make the stickers brighter?
- Choose suitable surfaces.Try to use them on clean and smooth surfaces and don’t use them on rough or wet surfaces.A rough surface reduces the contact area, while a wet surface affects the adhesive’s effectiveness.
- Use a UV blacklight.The pigment enjoys this high-intensity UV light,so it can fully charge in a few seconds.
- Charge them correctly.Direct sunlight works best and it can fully charge the stickers in 15 to 30 minutes.White LED lights are also effective.
- Keep the stickers clean.Wipe the sticker with a soft and damp cloth regularly to prevent dust from blocking Ultraviolet rays.
Can luminous stickers be used in high or low-temperature environments?
Normal temperatures (-20℃ to 60℃) have no effect on brightness and afterglow.Only extreme high or low temperatures will have a negative impact.Therefore,in daily life, we don’t need to worry about the temperature.
