7 Tips of Manufacturing Safety Glass with EVA Hot-melt Dry Adhesive Film
By Peter Shin helloglass.com

Attentions for Making Laminated Glass with Colored EVA Film
Because of the specialty of EVA Film, when you making high quantity of
colored laminated glass with colored EVA Film.

1-Carefully use different orders of colored EVA Film in one design,
even you order from same EVA Film manufacturers, 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 to compare 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.

Attentions when manufacturing laminating glass with EVA Film in rainy day
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 of the 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.

Attentions for Laminating EVA FILM With Decorative Interlayers
by Peter

The differences between laminating EVA Film and Laminating PVB Film is
that EVA film’s melt index is higher than PVB FILM, so glass
laminating with EVA Film is more convenient to interlayered some
decorative films, like fabric or melt wet.
So many glass processing factories making decorative laminated glass
sandwiched with all kinds of decorative 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 the interlayer is friendly with EVA Film.
Maybe of the printing ink or other dye materials, then decorative
interlayer have some chemical substances 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, the interlayers should stand higher temperature
than the EVA Film processing temperature.

Avoid Leaking of EVA Film inside Laminated Glass
The principle of making laminated glass is heating and vacuuming
(pressing the glass to squeeze out the air).
And when heating ,the EVA Film melt into liquid and it’s melt index is
higher than PVB Film. So when vacuuming (the glasses get the
pressure), the EVA Film near the edges of the pre-laminated glass will
leaking 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 tape to help vacuuming.
(2)-f you make small laminated glass, you can put some woods
surrounding the pre laminated glass. The surrounding woods should be
as high as the pre-laminated glass. Which can make sure that the
pressure is even on the pre-laminated glass.

Cooling the Laminated Glass after Heating
If get the laminated glass out of the silicone vacuum bag too early,
the temperature of the laminated glass is still higher than the room
temperature, if the balance is too much, the laminated glass may get
burst, 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 room temperature.

Attentions for Edging Laminated Glass With EVA Film
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 edge the EVA laminated glass after
heating.

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

4-Please use the gentle grinding wheel to edge the EVA laminated glass
First in first out:RULE OF STORAGE OF EVA FILM
BY PETER SHIN
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 to 1 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 transparency will be decline.
