[Ethylene Vinyl Acetate EVA Interlayer Film for Laminated Glass]
EVA Film
EVA stands for Ethylene Vinyl Acetate Copolymer, a copolymer resin used in the production of laminated glass as the interlayer film sandwiched between two pieces of glass, like PVB Interlayer Film, and SGP Interlayer Film. The main function of the interlayer is to stick the two piece of glass together, in order to make the sandwiched glass safer and more secure.

EVA Film performs excellent in bonding strength, heat resistance, cold resistance, humidity resistance and tensile strength in laminated glass. It has been partly taking the places of PVB film in laminated safety glass, laminated art glass, and laminated color glass.
EVA film is not adhesive at room temperature. After heating, it melts and has cross-link reaction. In the production of laminated glass with EVA interlayer film, no autoclave, roller press, air bag, or vacuum rubber ring is required. As EVA interlayer Film can be processed under normal climatic conditions, no clean room with climatic control is required in PVB lamination. And the laminating machine line of laminated glass with EVA Film is less cost and easier to install. All laminating processing will be finished and completed in one vacuum laminator. EVA Film for laminated glass has excellent transparency, outstanding adhesion and aging-resistance (more than 15 years), can be used for architectural glass, decorative glass with fabric, privacy glass, auto glass etc.

Advantages of EVA film :
– High tensile strength
– Excellent transparency
– Outstanding adhesion
– UV protection
– High impact resistance
– Good temperature withstanding
– Water proof
– Humidity durable
– Long-term reliable (long-term aging resistance)
– Sound barrier

[Introduction of EVA Interlayer Vacuum Bag Laminating Glass Machine]
EVA Vacuum Glass Laminating Machine is a equipment specially designed for manufacturing laminated safety and decoration glass with Ethylene-vinyl acetate EVA Interlayer Film (some kind of the one-step glass laminating machine can also processing Polyvinyl Butyral PVB Interlayer Film).
The EVA Vacuum Glass Laminating Machine uses the silicone vacuum bag to make the pre-laminated glass is heating in the vacuum condition to guarantee that final laminated glass don’t have bubbles.
It’s also possible to laminate EVA Interlayer Film with silk, paper, calligraphy and painting, ultraviolet radiation unilateralism film, light adjusted film and so on. All kinds of art glass, decorated glass, privacy glass, safety glass and solar panel can be processed in the EVA Vacuum Glass Laminating Machine.
Compared to autoclave producing line for Polyvinyl Butyral PVB Interlayer Film, the EVA Vacuum Glass Laminating Machine is much easier to operate and less cost to build., and more flexible and convenient for the designer.
(Notes: the knowledge here is a general guide, there is no guarantee that they are all correct or suits your laminating machine. )

7 Tips of Manufacturing Safety Glass with EVA Hot-melt Dry Adhesive Film
By Peter Lin

Attentions for Making Laminated Glass with Colored EVA Film
Because of the color tolerance 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 have color tolerance 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 uniformity.

2-When you make colored laminate glass in same design with the long time storage colored EVA Film, please make small samples to make sure the color of EVA Film is not changed 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 absorb 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 dry 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
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 sand-witch some decorative films, like fabric or melt wet.
So many glass processing factories making decorative laminated glass sandwiched with all kinds of decorative inserts by EVA Film.
But there are some tips:
1-Every time, you adopt new decorative inserts interlayers, make sure you do some test to check if the inserts interlayer is friendly with EVA Film.
Maybe because of the printing ink or other dye materials, then decorative inserts have some chemical substances that can do harm to EVA Film.

2-Make sure the design of the decorative inserts dry already before laminating EVA Film.

3. Make sure you understand the how high temperature the decorative inserts can stand, the inserts 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 pre-laminated glass get the pressure), the EVA Film near the edges of the pre-laminated glass will be 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 green tape to seal the pre-laminated glass, but make sure you make some small holes on the green tape to help vacuuming.
(2)-If you make small laminated glass, you can put some wood bars 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 you 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
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 or transparency will be decline.
