In the market, the homogenization of consumpsion has become increasingly severe, with similar products showing high similarity in terms of functionality, appearance, and other aspects. Brands are engaged in fierce competition to capture a limited market share. How to make the products stand out and quickly catch the consumers’ attention has become a critical challenge that many companies are eager to solve.

Innovations in packaging materials may be a key breakthrough point to improve product competitiveness. One of our Asian customers, for example, uses glass bottles for its product packaging. Ingeniously, the customer sprayed glow in the dark paint on the surface of the glass bottles, which had a significant effect. This not only increased the attractiveness and interest of the packaging material itself, but also added selling points to its own consuming products, winning the favor of many consumers and improving the competitiveness of its products.

Customer Demand and Challenge

The client is mainly engaged in the production of a consumer product, and hope to innovate the common transparent glass bottle packaging by incorporating luminescent elements to enhance the market appeal of their products. Previously, the client had tried some glow in the dark powders and make their own luminous paints for spraying, but the brightness was insufficient, and the final product’s glow effect did not meet their expectations.
The client wanted the glow powders with higher brightness to make sure their product has a strong glow in dark,then it can rapidly attracting more attention of the consumers. Due to the brightness of the end product is related to many propertities of the glow powder, to make a accurate match to their needs, we had a detailed communication with the client about their producing process, spray gun nozzle size, and previous testing results etc. We learned that they using a spray gun with a nozzle size of 0.8mm, which is relatively small, and thus, required finer glow powders. However, generally, the larger the glow powder particles, the higher the brightness. Therefore, the key issue we needed to address was how to ensure a brighter glow effect while maintaining smooth spraying performance with fine powders.

Solution: Two Types of Glow Powders for Testing

In response to customer needs, we recommended two types of luminous powder for testing: 20-30μm ultra-high brightness particles, and 10-14μm super-fine particles. In theory, these two different sizes of particles can pass through a 0.8mm caliber spray gun. But in actual use, the smoothness of spraying is also affected by the degree of deposition around the nozzle during use, so customers need to select the best particles through experiments.

20-30μm Ultra-High Brightness Particles: This glow powder belongs to our ultra-high brightness series. It has a higher initial brightness and longer afterglow time compared to regular grades. Additionally, it offers good coverage during actual application, providing a more uniform glowing effect on the product’s surface. Since its particles are larger than the 10-14um variety, it also tends to have higher brightness. If there is not too much residue around the nozzle, this powder should be used smoothly.

10-14μm Super-Fine Particles: This glow powder belongs to the super-fine series, with smaller particles that can pass through a 0.8mm nozzle more smoothly. However, since its brightness is not as high as the 20-30μm ones, and its cost is relatively higher, this type can serve as a secondary choice.

We suggested the client to test both types of glow powders, observe their spraying smoothness, and compare the final product’s glowing effect to make the most suitable choice.

Client Test and Feedback: 20-30μm Ultra-High Brightness Particles Performed Better

The customer conducted a test based on our suggestions. The results showed that after using 20-30μm ultra-high brightness particles, the luminous effect of the glass bottle was significantly better than that of 10-14μm super-fine particles, and there was no clogging of the nozzle during the spraying process. At the same time, compared with the luminous powder they used before, this 20-30μm particle has higher brightness and longer luminous time, and the application effect is better, which fully meets their needs for luminous effect.

Based on this result, the customer immediately decided to place a formal order and urged us to speed up the production schedule so that they can bring consumer products packaged in this luminous glass bottles to the market as soon as possible. Encouragingly, the market response far exceeded expectations. To seize the market opportunity, they placed multiple follow-up orders in a short period.

This product’s clever integration of luminescent elements in its packaging design proved to be a significant innovation. With the unique glow effect, the product successfully captured consumers’ attention, standing out in a fiercely competitive market, significantly improving the brand image, and achieving remarkable success.

Application Prospects of Luminescent Elements

This case proves that luminous elements have great potential in the innovation of consumer product packaging. In addition to being mixed with paint, luminous powder can also be mixed with ink, plastic and other media for printing, injection molding and other processes. Its wide range of uses provides great flexibility for brand packaging design and creates more possibilities for brands to create a unique product image in the market.
