Bubbles Problems of Laminating Glass with EVA Film (1)

Bubbles Problems of Laminating Glass with EVA Film (1)

I wrote an article Bubbles Solution for Laminated Class with EVA Film, talked about the situations that bubbles come out the laminated glass. It is macro views. Today I like to talk about the other reasons in micro views that cause the bubbles in laminating glass with EVA Film.

1. The plainness of the tempered glass is bad.

1) As you known, tempered glass is less plain than the flat glass. So you should choose a company that produce better tempered glass.

2) Since the tempered glass’s plainness is worse than flat glass, you should use thicker EVA FILM interlayer for the tempered glass. Generally speaking, the tempered glass should be laminated with at least 1.52 mm thickness EVA Film Interlayer.

3) Only laminate one layer “pre- laminated glass” in a silicon bag every time. If you laminate two or more layers “pre-laminated glass” in a silicon bag, the vacuuming would not work perfect and cause the bubbles.

4)  If you laminated small pieces “pre-laminated glasses” at the same time, put the “pre –laminated glasses” in good warp and weft, which will help vacuum.

2. Check if the silicon bag is leaking.

1) Averagely speaking, a silicon bag can be used for several years. But check the silicon bag if your laminated glasses have bubbles.

2) Check the concavo convex of the edge of the silicon bag is sealed perfectly when processing laminated glass with EVA Film.
