The key points about good quality silicone bags for glass lamination:
Key Features of Good Quality Silicone Vacuum Bags–Material: High-quality silicone rubber sheets with excellent durability and flexibility. Temperature Resistance: Ability to withstand temperatures up to 250°C (482°F). Strength and Flexibility: Strong yet flexible material suitable for wrapping around glass during vacuum processes. Reusability: Durable and reusable design for cost savings. Customizable Size: Available in various sizes, including widths up to 3300mm (130″). Sealing System: Three-stage interlocking vacuum seal for robust and long-lasting performance. Additional Components: Come with a breather sheet and vacuum valve. Important Considerations–Thickness: Common thickness is 3mm, but customizable options like 2mm or 1mm are available. Color: While color doesn’t affect quality, common colors are white or blue. Storage: Store at room temperature (20-25°C), away from grease and dirty water. Avoid direct sunlight and rain. Maintenance: For humid conditions, preheat the bag along with the PTFE open mesh before use. Protective Layer: Include a PTFE mesh (4mm x 4mm or 2mm x 2mm) to protect the bag from scraping. Best Practices–Ensure proper sealing: Use E-seals or U-seals on the four edges for perfect tightness. Use PTFE mesh: Prevents glass from scratching or puncturing the bags. Follow SOP: Adhere to standard operating procedures when using the vacuum silicone bag in the laminating glass furnace. Consult suppliers: Discuss specific requirements with EVA film and machine suppliers for optimal process parameters.
By considering these factors and following best practices, you can select and use high-quality silicone vacuum bags effectively for glass lamination processes.
