When it comes to custom paper air fresheners, especially in the promotional gift industry, color fading is a common issue that raises concerns among clients. At GoPromoLogo, a leading air freshener manufacturer based in Guangzhou, China, we often receive questions like: “Why do air fresheners fade?” and “How can we prevent discoloration while ensuring long-lasting scent?”
In this article, we break down the two main types of paper air fresheners in the market and explore the reasons behind fading and how we address them.
1. Two Types of Paper Air Fresheners
a. Direct-Printed Air Fresheners (Little Trees Style)
This style involves directly transferring or screen-printing graphics onto the absorbent material. It’s a popular choice in the U.S. market (like the iconic Little Trees) but requires high MOQs—usually around 100,000 pieces per design. Because the scent and color are both absorbed into the same material, discoloration tends to be more stable. However, production costs and order flexibility are significant drawbacks for small businesses.
b. Common Sandwiched Design (Our Standard Style)
Our regular production method uses a printed surface paper with absorbent cotton paper sandwiched in the middle. This allows for lower MOQs (as low as 500pcs), supports multiple designs in one batch (2–3 designs), and makes customization easier. However, this method is more prone to color fading, especially when exposed to certain fragrance oils.
2. Causes of Color Fading in Paper Air Fresheners
a. Ink and Printing Treatment
We apply specialized ink treatments to reduce bleeding and fading. However, standard CMYK printing can still be sensitive to certain fragrance chemicals.
b. Reaction Between Fragrance and Ink
Some fragrance oils—especially those with high alcohol content or citrus bases—can react with printed inks and cause the artwork to fade or blur. To prevent this, we test fragrance-ink compatibility during development.
c. Soaking Time Control
Excessive soaking of the absorbent layer in fragrance oil can lead to bleeding. We strictly control immersion time to maintain the appearance and scent balance.
d. Glue and Adhesive Quality
Poor-quality glue or improper use may react with fragrance, leading to discoloration. We only use tested adhesives that resist such chemical reactions.
3. Fragrance Longevity Factors
The staying power of a custom air freshener depends on:
- Fragrance quality: High-grade essential oils last longer and release scent evenly.
- Fragrance percentage: The ratio of oil to paper affects diffusion and longevity.
- Scent type: Citrus fades faster, while woody or musk-based scents tend to linger.
We offer over 17 standard scents and also support essential oil-based custom formulas.
Conclusion
Color fading in paper air fresheners is a manageable issue when the right materials and processes are used. At GoPromoLogo, we combine experience and rigorous testing to ensure your custom air fresheners are vibrant, aromatic, and durable.
