Storage Notes of EVA Film for Laminated Glass

Storage Notes of EVA Film for Laminated Glass

by peter shin

If you have imported some EVA interlayer film before, you would know that every EVA Interlayer film manufacturers will give some attentions of storage of EVA interlayer film.

Today we are going to talk about this topic in more detail.

1.Heavy burden shall not be laid on the EVA interlayer film and the EVA interlayer films shall not be piled up more than three-layer.

2.The EVA interlayer films should be used up in time after the packaging is opened; if not, please re-pack. And the storage period should not exceed 12 months( Different EVA interlayer film manufacturers has different shelf life of EVA interlayer film.).

3. Please fully confirm the corrosive and permeability of the edge sealing reagent and glass glue before laminating EVA interlayer film , for those may lead to EVA interlayer films breaking away from glasses!

4. Avoid sunlights and thermal radiations. And the temperature of storage environment should be under 45 degree.

5.Don’t store or transport EVA interlayer film with combustible or explosive materials.

The Packaging of EVA Interlayer Film for Laminated Glass

How the EVA interlayer film manufacturers package the EVA interlayer film? Especially the importers of EVA interlayer film would care about this much.

So today we are going to talk about this topic.

1.The EVA interlayer film manufacturers firstly seal the EVA interlayer film by PVC, then package it by the paper skin. And for the EVA interlayer film exported to foreign country and shipped by sea, it will also packaged by the wooden box to protect the EVA interlayer film.

2.If you have specific requirements of the packaging, you can tell the EVA interlayer film manufacturers, normally they will do as you said. But there maybe some added cost of the customized packaging.

3.Some EVA interlayer film manufacturers have tried to use the vacuum sealed packaging to avoid the moisture of the EVA interlayer film.

In next post, we are going to talk about the notes of storage of the EVA interlayer film.

Heating Procedures of Laminating Glass with EVA Film

Heating Procedures of Laminating Glass with EVA Film

By Peter Shin

Last post we talked about Preparation for Glass Lamination with EVA Film.

And this post we are going to talk about Heating Procedures of Laminating Glass with EVA Film.

1.Before the silicon bag shelf being pushed into the oven, start the vacuum pump to vacuuming for 3-5five mins. Check whether the silicon bag is leaking or not. And the vacuum value should at least be 0.095Mpa.

2.Push the silicon bag shelf into the oven, then set the parameters of temperature and time. Following two period heating temperature. The low temperature period is 55degress and 15mins. And the high temperature period is 110 degree and 50 mins (notes;following the instructions that the EVA FILM MANUFACTURERS give you). Because it takes time for the heat transfer through the silicon bag, so the temperature the detector gets may be different from the real temperature of the laminated glass.

3.Stop heating. Wait till the temperature is lower than 75 degrees, then open the oven door and pull out the silicon shelf to help cooling. But don’t open the silicon bag or let cold water tough the laminated glass.

After the temperature is lower than 50 degree, now you can open the silicon bag and check the laminated glass.

Preparation for Glass Lamination with EVA Film

Preparation for Glass Lamination with EVA Film

By Peter Shin

Today we are going to talk about the Glass Laminating Instructions of EVA Film. This topic will be composed into two posts. This post is about the preparation for glass lamination with EVA Film.

Preparation for Lamination:

1.Cut the glass as the size you want, and use  Glass Edging Machines to shape the edges of the glasses, which will avoid the glasses hurt the silicon bag.

2.Use the purified water, deionized water, industrial alcohol, Ethanol to clean the glasses, then use the clean hot wind to dry the glasses. Make sure no black spot, water mark, finger print etc on the glasses.

Pre-Laminating:

Put the EVA FILM on the bottom glass, make sure the EVA Film is plain, then put the other glass on the EVA Film, then use the high-temperature-resistance tape to seal the pre-laminated glass.

Cut the extra EVA FILM that outside the pre-laminated glass. Don’t pull the EVA Film hard to avoid the remove of the EVA Film. Which can void the extra EVA Film melting and sealing the edges of the laminating glass and stop the vacuuming.

When you put the pre-laminated glass in the silicon bag, make sure that each pre-laminated glass is 3-5cm away from each other to help vacuuming.

To help vacuuming, you can also put the wooden bar around the silicon bag to help vacuuming.

Notes: if you seal the pre-laminated glass totally with tape, you need to make some small holes on the tapes to help vacuuming.

Next post we are going to talk about the heating instructions.

Indoor Super-Transparent EVA Film for Decorative Laminated Glass

Indoor Super-Transparent EVA Film for Decorative Laminated Glass

By peter shin

Fist let’s  repeat the differences between the “Outdoor Super-Transparent EVA Film for Architectural Safety Laminated Glass” and “Indoor Good Transparent EVA Film for Decorative Laminated Glass”.

Based on transparency:

Outdoor Super-Transparent EVA Film for Architectural Safety Laminated Glass” is much more transparent than  “Indoor Good Transparent EVA Film for Decorative Laminated Glass”

Based on UV blocked rate:

Outdoor Super-Transparent EVA Film for Architectural Safety Laminated Glass” can block 99% of the UV lights and can be used for outdoor, of which the weather resistance is more than 20 years.

“Indoor Good Transparent EVA Film for Decorative Laminated Glass” can not block the UV lights and can not be used for outdoor.

Buy some customers would ask how if i want the super-transparency, buy used for indoor?

Yes, that’s the reason we build the new product:  “Indoor Super-Transparent EVA Film for Decorative Laminated Glass”, which has the super-transparency of the “Outdoor Super-Transparent EVA Film for Architectural Safety Laminated Glass“, but not blocking the UV lights. That’s means the “Indoor Super-Transparent EVA Film for Decorative Laminated Glass” will be less  inexpensive than the “Outdoor Super-Transparent EVA Film for Architectural Safety Laminated Glass“, but a little more expensive than “Indoor Good Transparent EVA Film for Decorative Laminated Glass”.

We totally believe that the “Indoor Super-Transparent EVA Film for Decorative Laminated Glass” will satisfied some customers’ need. And making our customers satisfied is our final aim.
