Silicone Vacuum Bag for Glass Lamination Machine Manufacturer
Reusable Silicone Vacuum Seal Bags Supplier
Silicone vacuum bags are critical consumables used in EVA glass lamination processes. A high-quality reusable silicone vacuum bag helps remove trapped air, stabilize the lamination stack, and significantly reduce defects such as bubbles, delamination, and edge leakage.
Suconvey supplies reusable silicone vacuum bags for glass lamination machines, designed for high-temperature cycling, repeated use, and stable vacuum sealing.
Our vacuum bags are widely used in architectural laminated glass, safety glass, decorative glass, and industrial glass lamination lines.
High Temperature Resistant silicone vacuum bag
A silicone vacuum bag is a flexible, airtight silicone rubber envelope used to enclose glass sheets and interlayers during lamination. By applying vacuum pressure, the bag removes air between layers and ensures uniform contact during heating and pressing.
Compared with disposable vacuum films, reusable silicone vacuum bags offer:
longer service life
more stable vacuum performance
lower long-term operating cost
consistent lamination quality

Why Silicone Vacuum Bags Matter in Glass Lamination
Vacuum bag quality has a direct impact on yield rate and production efficiency. Poor-quality bags often lead to:
unstable vacuum and air leakage
bubble formation inside laminated glass
surface imprinting and optical defects
frequent bag replacement and downtime
Our silicone vacuum bags are engineered to maintain stable sealing performance and tear resistance, even under demanding lamination cycles.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone bags in roll form are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test bags can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
Happy Customers
Year after year, multiple industries recognize Suconvey Rubber as a leader in quality, service, and innovation. We’re proud to be one of the top rubber products manufacturers in the world.
Frequently Asked Questions
If your question is not listed, please contact us.
A silicone vacuum bag is used in EVA glass lamination to remove trapped air between glass and interlayers, ensuring uniform pressure and preventing bubbles or delamination.
Service life depends on lamination temperature, cycle frequency, and handling. Under normal conditions, a high-quality silicone vacuum bag can be reused for many cycles before replacement.
Typical silicone vacuum bags can handle temperatures up to 260°C. For higher or prolonged temperature exposure, special silicone compounds can be used.
Vacuum bag size should match your lamination machine and maximum glass dimensions. Providing machine model or drawings helps ensure proper fit.
Common causes include poor sealing edges, material aging, surface damage, or improper bag size. Using a properly designed silicone vacuum bag reduces these risks.
Yes. We provide custom silicone vacuum bags based on drawings, samples, or machine specifications, including size, thickness, and surface finish.
