Because of the specialty of EVA Film, when you making high quantity of colored laminated glass withcolored EVA Film.

1. Carefully use different orders of colored EVA Film in one design, even you order from same EVA Filmmanufacturers, the color of the EVA Film may be a little different in different producing schedule.

If you use colored EVA Film of different orders in one design, make you sure you make small samples tocompare the color effect.

2. When you make colored laminate glass in same design with the long time storage colored EVA Film,please make small samples too to make sure the color of EVA Film is not change among the storage.

In rainy days, the humidity in the air is high.

And also, it's easier for the surface of glasses and EVA Interlayer film to catch the humidity.

The humidity in the surface of glasses and EVA Film will do harm to the adhesive of EVA Film,sometimes will cause bubbles.

So, when in rainy days, please pay attentions to the processing room, and double clean the surface ofthe glasses, and seal the EVA Film roll, when you are not using it.

And also you can prolong the low temperature period to dry the humidity away.

The differences between laminating EVA Film and Laminating PVB Film is that EVA film's melt index ishigher than PVB FILM, so glass laminating with EVA Film is more convenient to interlayered somedecorative films, like fabric or melt wet.

So many glass processing factories making decorative laminated glass sandwiched with all kinds ofdecorative interlayers by EVA Film.

But there are some tips:

1. Every time, you adopt new decorative interlayers, make sure you do some test to check if theinterlayer is friendly with EVA Film.

Maybe of the printing ink or other dye materials, then decorative interlayer have some chemicalsubstances that can do harm to EVA Film.

2. Make sure the design of the decorative interlayers is dry already before laminating EVA Film.

3. Make sure you understand the how high temperature the decorative interlayer can stand, theinterlayers should stand higher temperature than the EVA Film processing temperature.

The principle of making laminated glass is heating and vacuuming (pressing the glass to squeeze outthe air).

And when heating ,the EVA Film melt into liquid and it's melt index is higher than PVB Film. So whenvacuuming (the glasses get the pressure), the EVA Film near the edges of the pre-laminated glass willleaking out.

And if the EVA Film is leaking out too much, the edges of the laminated glass may have bubbles around.

There are two ways to solve this problem:

(1) Use the tape to seal the pre-laminated glass, but make sure you make some small holes on the tapeto help vacuuming.

(2) If you make small laminated glass, you can put some goods surrounding the pre laminated glass.The surrounding goods should be as high as the pre-laminated glass. Which can make sure that thepressure is even on the pre-laminated glass.

If get the laminated glass out of the silicone vacuum bag too early, the temperature of the laminatedglass is still higher than the room temperature, if the balance is too much, the laminated glass may getburst, or there may be some bubbles around the edges.

In summer, if the room temperature is high, you can use fan to help cooling the glass.

But anyway, don't stop vacuuming until the temperature of laminated glass is close to the roomtemperature.

1. Don't edge the laminated glass until the laminated glass with EVA Film has been cooled for 24 hours.Because if you edging too early may cause the delamination in the edges of EVA laminated glass.

2. It's better if you can edging the glasses before laminating with EVA Film, then you don't have to edgethe EVA laminated glass after heating.





3. If you laminated with some decorative interlayer inside the glass, and the decorative interlayer is easyto absorb water, then you should edging the glasses before processing laminating with EVA Film.Because if you have to edge after heating, the decorative interlayer may absorb water and lead to thedelamination.

4. Please use the gentle grinding wheel to edge the EVA laminated glass

When we talking about storage of EVA Film.

Most EVA Film manufacturers will guarantee that self life of EVA Film for laminated glass is 6 months to1 years.

So when store the EVA Film, please remember "first in first out" rule.

Make sure you use the EVA film you order early.

And also make sure you use the EVA Film during the self life period.

Because after the EVA FILM expired, maybe the adhesive strength, impact strength and transparencywill be decline.
