The Processing Temperature and Time for Laminating Glass with EVA FILM

The Processing Temperature and Time for Laminating Glass with EVA FILM

By peter shin

Last night I talked to an engineer who has been in laminating glass with EVA FILM for more than ten years. We talked a lot about the problems may come out in processing procedure. And he gave best advice for them.

Today I like to talk about the processing temperature and time for laminating glass with EVA FILM.

First I would to say that no fixed value for the processing parameters, because different EVA film manufacturer have different formula for the EVA FILM, and different glass laminating machine manufacturer have different property for the machine.

What’s more and weather and moisture is different in different regions, which also would affect the processing parameters.

So there is no fixed value for the processing temperature and time for laminating glass with EVA FILM.

But I can tell you some general rules of the processing parameters for laminating glass with EVA FILM.

1.) Indoor EVA FILM (like 110 degrees) need lower temperature for laminating than outdoor EVA FILM (130 degrees).

2.) If you laminating thicker glass with more layers of EVA FILM, then the keeping time should be longer, for example if 5mmglass+0.38mm EVA FILM +5mm glass is 130 degree and 40 min, then 10mm glass+2layer EVA FILM +10mm glass should be 130 degree and 55mins.

Because more time is needed for the heat pass through the thicker glass and more layer EVA FILM.

3.) The tempered glass laminating with EVA FILM needs longer keeping time than the flat glass laminating with EVA FILM.

4.) If the weather is colder in your region, then the keeping time should be longer.

And it’s also different for different glass laminating machine, because the heating part is different.

So :

1.) If you change the EVA FILM supplier, maybe you have to adjusting the processing parameters for laminating glass with EVA FILM.

2.) If you buy a new EVA glass laminating machine, and the processing parameters maybe different from your older one.

3.) If the weather changes from different seasons, maybe you also need to adjust the processing parameters for laminating glass with EVA FILM.

4.) Yes, every EVA FILM Manufacturers would offer you the processing instructions or parameters for laminating glass with EVA FILM, but you don’t have to follow them exactly. You should change some according to your real situation.

Hope all those info may be helpful to you.

Fantastic Digital Laminated Glass

Pepter’s comments:

DIGIGLASS do a great job, they laminated the digital image with the glass. That very fantastic. and i almost shocked.

I have read it’s website, and they don’t say the laminated interlayer is EVA FILM, but i think EVA FILM would work a better job here than PVB FILM, because EVA FILM‘s liquidity is better than PVB FILM when melted and pressed.

the following is DIGIGLASS’ introduction for his website:

Decorative Safety Glass has never been more versatile or easy with DigiGlass

SentryGlas® Expressions™ is created by encapsulating a computer or photographic image in full colour, high resolution, in Class One safety glass.

Specially developed proprietary inks and interlayers are used in combination to offer the ideal adhesion, resolution, and dimensional properties needed for artistic imaging in laminated glass.

Decorative Glass the Easy Way

As SentryGlas® Expressions™ uses a computer-based digital imaging system, it is exceptionally efficient and versatile, opening up a broad range of application possibilities. Continue reading “Fantastic Digital Laminated Glass”

EVA FILM Category (2)

EVA FILM Category (2)

This morning I sent EVA FILMS to port. And it’s obvious that the international trade is booming in China. Long line is waiting for the loading container.

Ok let’s go back to the topic, today we are still going to talk about the EVA FILM categories. Finish what we started.

Last post we talked about the categories based on UV BLOCKED RATE and TRANSPARENCE. Let’s continue:

Based on colors, EVA FILM can divide into:

-no color transparent

-colored transparent (standard 8 colors in China)

-colored translucent (standard 7 colors in China)

-colored opaque

-Black (transparent, translucent, opaque)

-white (transparent, translucent, opaque)

The standard colors are:









Some companies can customize the color you need it (not included in the standard colors), you offer the samples, and they will adjust the color film samples for you to check. But of course, the cost would be higher. It’s different from the quantity of the color you want to customize.

Based on thickness, the EVA FILM can divide into:

0.25 mm



But some companies produce the same thickness with the Japan’s common standard:



Also, the EVA FILM manufacturer can customize the thickness for you, but for this customizing, the added cost would be very low, some EVA FILM manufacturer may not charge for it.

If you have different views, please communicate with me in the comments. You are warmly welcome.

EVA FILM Category (1)

Today I would like to talk about the categories of EVA FILM.

Based on the UV Blocked rate, the EVA FILM can divided into :

Indoor EVA FILM and Outdoor EVA FILM.

Indoor EVA FILM, of course, the UV blocked rate is lower than 30%. So they can only be used inside building.

But how is it going to happen, if I put the indoor EVA FILM laminated glass in outdoor using?

That is a great question. And the answer is that the indoor EVA FILM laminated glass will turn yellow in short period, maybe two years, and bubbles will come out inside the laminated glass, and the EVA FILM will break away from the glass.

For outdoor EVA FILM, the most advanced EVA FILM can absorb 99% of the UV radiation.

But at least the UV radiation should be absorbed more than 85% percent that the EVA FILM can be used for outdoor.

It’s logical that more UV radiation absorbed by EVA FILM, more years the laminated glass with EVA FILM will survive.

Yes, it’s not necessary to say but I want to mention that you can use the outdoor EVA FILM for indoor.

Based on the transparence, the EVA FILM can divide into:

Ordinary transparent and super transparent.

Ordinary transparent, of course, means the transparence is good but less than super transparent. Most ordinary transparent EVA FILM is used in laminating with fabric and papers.

And generally speaking, the ordinary transparent EVA FILM are INDOOR EVA FILM. And super transparent EVA FILMs are outdoor EVA FILM.

But some people also used super transparent EVA FILM to laminate with fabric and papers.

But because some people need the super transparence but not the UV blocked rate, some EVA FILM manufacturer make the INDOOR super transparent EVA FILM.

China’s EVA FILM compared to Japan’s EVA FILM

China’s EVA FILM compared to Japan’s EVA FILM
Yes, EVA FILM was first implied in Japan, like Bridgestone. At that time,  no other countries had used EVA FILM to laminate glass(Maybe i am wrong, welcome to correct me). Yes EVA  has been used in others fields, like slipper and   insider of cloth etc.
Not many years later, EVA FILM was introduced to China. but the quality is not very good.
The EVA FILM is only used in decorative glass. Which mens the safety of EVA FILM is not trusted.
But now in China, the EVA FILM after modified by lots of times, are in good quality.
And some European customers change the suppliers of EVA FILM to China suppliers, because EVA FILM in China is inexpensive but at the some quality of EVA FILM in Japan.
As we have compared EVA FILM in China and Japan.
The visible light transmission and ultraviolet light blocked rate are as good as EVA FILM in Japan.
