In EVA glass lamination processes, the combination of teflon mesh and vacuum silicone bag is essential to achieving smooth, high-quality laminated safety glass. Each material serves a specific function, and when used together, they ensure efficient air evacuation, uniform heating, and excellent lamination results. Understanding why the teflon mesh must work together with the vacuum silicone bag helps glass manufacturers avoid common lamination problems such as bubbles, wrinkles, and uneven bonding.
The primary purpose of teflon mesh is to create air channels during vacuuming. When laminated glass is placed in a vacuum silicone bag, the teflon mesh allows air to escape evenly from all surfaces. Without teflon mesh, air pockets can form between glass layers or around EVA film, leading to bubbles and optical defects. The teflon mesh ensures consistent airflow and proper vacuum distribution across the entire glass surface, which is crucial for perfect lamination quality. Additionally, teflon mesh is heat-resistant and provides mechanical support, preventing the EVA film from sticking to the vacuum silicone bag.
The vacuum silicone bag creates the sealed environment required for lamination. It provides flexibility, heat resistance, and durability under repeated vacuum cycles. When pressure is applied, the vacuum silicone bag conforms to the glass surface and ensures uniform compression of EVA film. However, the silicone surface alone does not allow smooth air evacuation across the full glass area, making the teflon mesh a necessary companion.
When the teflon mesh is placed inside the vacuum silicone bag, air evacuation becomes faster and more consistent. This synergy prevents defects like:
Bubbles inside laminated glass
Uneven adhesion
Optical distortions
Wrinkles and shifting of EVA film
Moreover, the teflon mesh protects the inner surface of the vacuum silicone bag from mechanical abrasion and polymer residue deposits, which extends the working life of the silicone bag.
In summary, the teflon mesh and vacuum silicone bag must be used together to ensure optimal EVA glass lamination performance. The teflon mesh enhances vacuum flow, improves lamination uniformity, and protects the vacuum silicone bag, while the silicone bag provides airtight sealing and pressure distribution. Together, they create a reliable lamination environment that delivers bubble-free, clear, and high-strength laminated safety glass for architectural and industrial applications.
