Notes When Using the Silicone Vacuum Bag/Sheet 1. Please edging the glass before

laminating, which can prohibit the sharp glass edges of the glass cut the silicone bag.

2. Use tape to seal the pre-laminated glass to reduce the EVA leaking from the laminated glass.

3. Use some papers to cover the silicone bag to separate the EVA from the silicone bag

4. Put some wires net on the vacuum hole to help vacuuming.

5. When not laminating , put the silicone bag out of the hot oven.
