A transparent tank refers to e-cigarette devices that utilize high-transparency polymer materials such as PETG, PCTG, and PC for e-liquid storage. Unlike the regular integrated wick and reservoir disposable vapes, this design eases the anxiety in the case of e-liquid running out. It allows users to monitor the e-liquid level and condition in real time during use.
As the big puff disposable vape market continues to evolve, this product category is emerging as a key trend in 2025 not only in the US, but also in Southeast Asia and across European markets.
At the Dubai World Vape Show in June, this trend became even more evident. Almost every leading brand showcased their latest disposable vape devices using tags like “visible e-liquid tank,” “crystal tank,” or “visible coil.” Nearly half of the products exhibited by SMOORE, the world’s largest vape manufacturer, adopted this visible e-liquid tank design.
1. Real-Time E-Liquid Monitoring – Reducing "E-Liquid Anxiety"
A visible e-liquid tank enables consumers to check e-liquid levels at any time, providing a more convenient way to observe the remaining liquid. Since the e-liquid condition is always visible, this effectively alleviates concerns about running out of liquid, enhancing the sense of security and improving the overall user experience.
2. Improved Atomization and Moisture Retention
Unlike the regular big puff disposable designs, a transparent tank with a special internal structure inside, in which the cotton and coil are immersed in e-liquid all the time, this method significantly improves e-liquid moisture and smoothness which is quite similar to the performance of RDA device. This ensures that each puff delivers a richer, fuller vapor while reducing any dry or harsh sensations.
3. Lower Manufacturing Costs and Higher Cost-Effectiveness
The transparent tank structure is generally simpler and requires fewer materials than other e-cigarette designs with upgraded structure design. This results in a significant cost advantage, offering both manufacturers and consumers a more cost-effective solution.
4. Stylish, High-Tech Appearance That Turns Heads
Transparent tank designs bring a sleek, futuristic look that enhances the visual appeal of the device. The see-through structure conveys cleanliness and modernity while allowing users to appreciate the color and clarity of the e-liquid. On retail shelves, these designs stand out from opaque products, capturing attention and reinforcing brand recognition. For brands, it also opens up creative possibilities to highlight signature flavor colors or layered visual effects, turning the tank into a visual representation of the flavor itself.
3 Years of R&D Comes Out Hangsen’s Transparent Tank E-Liquid Solutions
Although transparent tank disposable vapes have been available for years, their widespread adoption has been limited by various technical challenges both the prevent-leaking technology of the device and the compatibility of e-liquid and the device.
The primary issues always revolve around the compatibility between e-liquids and devices. Since fully transparent materials expose the e-liquid to prolonged light exposure, any color changes or sedimentation become visible to consumers, requiring superior e-liquid stability. Additionally, compared to other e-cigarette structures, transparent tanks are more prone to leakage and spitting.
However, after three years of dedicated R&D and continuous refinement with projects, Hangsen has developed a highly advanced e-liquid adaptation technology for transparent tanks. Through extensive case studies and tests, such as stability testing, accelerated oxidation testing, and long-term light exposure simulations, we have systematically addressed these technical challenges. As a result, Hangsen now stands as one of the most mature and leading e-liquid manufacturers in this field.
1. Preventing E-Liquid Color Changing
Hangsen has developed a self-patented nicotine salt technology and high-efficiency stabilizer formulations to enhance e-liquid stability. This ensures no significant color degradation over time, maintaining transparency and vibrancy. Our solution effectively resolves the common issue of visible color changes that occur in traditional transparent tank vapes over prolonged use.
2. Preventing Leakage and Spitback
Hangsen’s technological solution precisely adjusts e-liquid viscosity and intensity to suit different device specifications. We ensure a high conduction rate of e-liquid with cotton while significantly reducing leakage and spitback issues, enhancing the reliability of transparent tank devices.
With Hangsen’s long-term expertise in transparent tank adaptation technology, we provide mature solutions for e-cigarette device manufacturers, enhancing user experience and driving the development and adoption of transparent tank technology.
