In chemical processing, laboratory research, optical manufacturing and solar PV industries, quartz glass tubes and borosilicate glass tubes are core consumables. However, problems like tube shattering and splashing, UV-induced material degradation, and surface scratching have long troubled procurement teams worldwide.
Most suppliers in the market only offer flat glass film lamination. For tubular glass products, film application is almost always done by hand. Over 90% of buyers have faced issues like bubbling, edge peeling, uneven thickness, and inconsistent batch quality, which not only fail to deliver proper protection but also cause rework costs and production downtime.
As a professional quartz product manufacturer with years of industry experience, Donghai JiuRui Quartz Products Co., Ltd. (JiuRui Quartz) has developed exclusive fully automatic machine lamination technology for tubular glass. We break the limitations of hand-applied films, providing professional quartz glass tube coating and borosilicate glass tube coating services with TPU, PVC and PET film options. Our solutions cover explosion protection, UV blocking, and scratch resistance, fundamentally solving bubbling and peeling issues, with stable batch quality. We are one of the few manufacturers in China capable of automated film lamination on round glass tubes. Explore our 4N8 high purity quartz tube products
Common Pain Points of Hand-Applied Glass Tube Films
The tubular glass coating market is highly fragmented. Most service providers have no professional equipment and rely entirely on manual operation, which brings many unavoidable industry-wide problems:
1. Bubbling & Edge Peeling, Failed Protection
Hand lamination suffers from uneven pressure and incomplete air exhaust. Finished products are highly prone to bubbles and wrinkles. After 1–3 months of use, edges often curl up and the film falls off completely, losing its explosion-proof and UV-blocking functions. In high-pressure and high-temperature working conditions, this may even cause safety hazards.
2. Uneven Thickness, Unstable Performance
Manual operation cannot precisely control film tension, resulting in large thickness tolerances. The film thickness varies at different positions on the same tube. For optical applications with strict transmittance and refractive index requirements, this directly distorts experimental data and reduces product yield. For explosion-proof scenarios, weak spots cannot provide effective protection.
3. Low Efficiency, Unreliable Bulk Delivery
Hand lamination takes a long time per tube. Bulk orders come with long lead times, and quality varies greatly between different workers. Batch-to-batch consistency is poor, making it impossible to meet stable supply requirements for large-scale production.
4. Limited Material Compatibility, Unmet Special Requirements
Most hand-lamination service providers can only apply standard PVC films. For high-performance films such as TPU explosion-proof films and PET optical films, they lack professional pre-treatment and lamination processes. The finished products have poor adhesion and peel off easily, failing to meet high-end requirements for explosion protection and UV blocking. View ASTM standard for pressure-sensitive adhesive films
Why Choose JiuRui’s Machine-Applied Quartz Glass Tube Coating
JiuRui Quartz has invested in R&D and introduced an automatic tubular film lamination production line. We are one of the few manufacturers mastering machine lamination technology for round glass tubes, completely solving all the drawbacks of hand-applied films and delivering stable, high-quality coating services.
1. Fully Automatic Roller Lamination: Zero Bubbles, Zero Peeling
We adopt CNC fully automatic roller lamination technology with precisely controlled pressure and feeding speed. Air is evenly exhausted during the whole process, and the film perfectly adheres to the tube surface. Finished products have no bubbles, no wrinkles, no edge curling. The adhesion strength is far higher than hand-applied films, and the service life of the film is increased by more than 3 times under normal use, fundamentally solving peeling and bubbling problems.
2. Uniform & Controllable Thickness: Consistent Batch Quality
With digital parameter control, the film thickness tolerance can be controlled within ±0.01mm. All tubes in the same batch have exactly the same lamination effect, with stable and controllable transmittance, explosion-proof performance and UV blocking rate. It is perfectly suitable for scenarios with extremely high precision requirements such as optics, laboratories and precision manufacturing.
3. Large & Long Tube Compatibility: Efficient Bulk Delivery
We support continuous film lamination for large-diameter and long-size tubes. We can handle glass tubes with diameter from 10mm to 300mm and length up to 4000mm. Our daily processing capacity far exceeds that of manual lamination. Even large bulk orders can be delivered within a stable lead time, meeting the needs of large-scale production.

4. Pre-Treatment & Curing Process: Enhanced Adhesion
Before lamination, we perform professional cleaning and surface activation treatment on the tube surface to improve the bonding force between the film and glass. After lamination, the product goes through a constant-temperature curing process to further strengthen adhesion. The film will not easily peel off or age even under high temperature, high humidity and acid-base corrosion conditions, adapting to complex industrial environments.
TPU / PVC / PET Film Options for Every Application
JiuRui Quartz supports tube lamination with a variety of mainstream film materials. We can recommend the most suitable film solution according to your application scenario and functional requirements. All films undergo strict quality control, ensuring bubble-free and peel-free performance after lamination.
1. TPU Explosion-Proof Film: High Elasticity & Impact Resistance
TPU film has excellent elasticity and impact resistance. When applied to the surface of glass tubes, it can firmly hold glass fragments in place even if the tube breaks under external force, preventing splashing injuries and greatly improving safety in high-pressure chemical reaction and high-temperature process scenarios. TPU film also has low temperature resistance and aging resistance, with strong adhesion and no easy edge curling after long-term use, making it the first choice for explosion protection.
2. PVC Functional Film: Cost-Effective Scratch & UV Protection
PVC film offers outstanding cost performance with good scratch and wear resistance. It can effectively protect the glass tube surface from hard object scratches and extend the service life of the tube. It can also be added with UV blocking ingredients to achieve over 99% UV blocking rate, preventing photodegradation and aging of materials inside the tube. It is suitable for general industrial and laboratory scenarios.
3. PET Optical Film: High Transmittance & Stability for Optical Use
PET film has extremely high light transmittance and optical uniformity. After lamination, it barely affects the light transmission performance of the glass tube. It also has excellent chemical stability, high and low temperature resistance, and acid and alkali corrosion resistance. UV-blocking PET film is available on request. It is the preferred film material for optical experiments, photovoltaics and precision analytical instruments.
