Blue PET Protective Film – Our Precision Die-Cutting Solutions
Our Die-Cutting Equipment
Our Blue PET Protective Film is processed in a Class 1000 cleanroom, ensuring it remains free from contamination throughout production. The automatic roll-to-roll lamination machines precisely bond adhesive layers to the PET film, delivering smooth, bubble-free surfaces that meet optical and protective requirements.
The automatic lamination waste removal system efficiently strips excess material without damaging the protective film, ensuring clean edges and minimizing production downtime. This automation not only boosts throughput but also guarantees consistent results across large production runs.
Our high-precision die-cutting machines handle intricate shapes with tight tolerances of ±0.01mm, enabling perfect alignment for applications such as electronics protection, screen lamination, and industrial surface masking.
Our Die-Cutting Quality Control
Dimensional precision is verified using our 2.5D measurement system, while dust particle counters continuously monitor the cleanroom environment. CCD and binocular microscopes detect micro imperfections, ensuring each piece of Blue PET Protective Film meets high visual and functional standards.
Peel strength testers validate adhesive performance, while thickness gauges ensure uniform material distribution. Environmental chambers test the film’s durability under temperature and humidity variations, and light transmission testing confirms optical performance when required.
In-process quality control stations (IPQC) monitor production using advanced measurement tools, while holding power testers verify long-term adhesion stability. For specialty applications, additional performance tests can be carried out as needed.
Our Inspection Team
Working in the Class 1000 cleanroom, our inspection team conducts comprehensive final checks on each batch of Blue PET Protective Film, ensuring no defects, dimensional accuracy, and application-specific performance before products are packaged and shipped.
Our Mold Management
Our in-house mold workshop uses CAD design, CNC machining, and laser cutting to create and maintain custom die-cut molds for Blue PET Protective Film. Each mold undergoes regular optimization and lifecycle management, ensuring consistent accuracy and efficiency in production.
Our Product Cases
One example is the production of dust-proof meshes and gasket rings for devices such as smartphones, earphones, and tablets, preventing dust intrusion while maintaining audio quality. These are produced using high-precision die-cutting and airflow permeability testing in a controlled cleanroom environment.
Another case is foam gaskets for smartphone camera modules, which both block dust and prevent light leakage. Our automated lamination ensures adhesive alignment, while precision die-cutting machines achieve complex geometries with consistent quality.
The third example is PET or PC sheets with protective films used in screen protection, insulation, and anti-scratch applications. Each piece undergoes strict dimensional measurement, surface inspection, and durability testing to ensure long-term reliability.

What is the adhesive strength and temperature range of Blue PET Protective Film?
The adhesive strength of Blue PET Protective Film typically ranges from 100g to 300g, and it can be adjusted to meet specific needs. It has a stable adhesive strength that holds well once produced.
For temperature, it can be used long-term between -40°C and 120°C. It can withstand short-term temperatures up to 150°C. This makes it suitable for various industrial and commercial uses.
How UV resistant is Blue PET Protective Film?
Blue PET Protective Film blocks over 99% of UV rays, protecting items from sun damage. It stays strong even after long UV exposure, with no reduction in performance after 2000 hours of testing. It also maintains clear visibility, allowing 88% light transmission, and is safe for outdoor use.
Can I reapply Blue PET Protective Film?
Yes, you can reapply Blue PET Protective Film if it has fallen off. Make sure the surface is clean and free of dust or oil. If the adhesive is weak, you may need extra glue. Ensure the temperature and humidity are suitable for better adhesion. Be gentle during the process to avoid damage.
What if the film gets cloudy?
If Blue PET Protective Film looks cloudy, check for moisture or dust. Keep the area dry and clean before applying. Press the film firmly to avoid trapped air. Use good quality glue and avoid too much heat. If unsure, ask us for help.
What if film shows swirl patterns?
If you see swirl-like marks (called Benard cells) on the surface of Blue PET Protective Film, it usually means the coating didn’t dry evenly. Here’s how you can fix or avoid it:
Control the drying speed – If the top dries too fast, the bottom solvent can’t rise up smoothly. Try to keep the drying temperature more stable and even.
Check coating thickness – Too thick or too thin coating can cause problems. Make sure it’s applied evenly.
Use a flow agent – This helps the liquid spread better during coating, reducing marks caused by surface tension differences.
Choose the right solvent – A solvent that evaporates too quickly can cause swirls. Slower, more balanced evaporation helps.
Improve production setup – Adjust how the liquid moves on the surface during coating. Smoother flow means fewer patterns.
Keep it clean – Dust or dirt in the air or on the surface can disturb the coating, so make sure the workspace is clean.
