EVA film is already an essential component of companies in the modern world, and you can even see it outdoors. If you are considering purchasing EVA film, you may need this introduction to its use.
EVA film will have different color distinction, at present mainly divided into transparent, white translucent, milky white and black these kinds of, general EVA film are transparent or translucent, in some special needs, will add some color material, on the formation of different colors of adhesive film. Today we come to know about White series EVA film.
White series EVA film is divided into light film, with release paper, with release film three styles, and the width, thickness can be customized according to the relevant requirements. eva film melting point at 80 degrees, generally applicable to the need for low-temperature composite materials. eva film is commonly used for wall coverings, shoes, photovoltaic modules and other industry-related materials.
How to use without release paper
Without release paper means that the EVA film is only a separate layer of adhesive, and does not have a backing paper, so the method of use is also relatively simple.
How to use the model with release paper (or release film)
The model with release paper means that there is a layer of release paper or release film on one side of a double-sided adhesive film. This is mainly to facilitate the operation of some applications that require secondary lamination, for example, trademark cloth that needs to be glued to the trademark first, and then peel off the release paper and bond it to the garment. EVA film with paper backing is used in two steps
In the first step, the EVA film is glued to one side of the material
EVA film with adhesive side facing one side of the material using pressing equipment for lamination, because the first step is pre-lamination, so the temperature of the equipment does not need to be too high, the general temperature is slightly higher than the melting point of the material can be, laminated and wait for it to cool down after tearing off the release paper (if you need to cut before tearing off the release paper), it should be stressed that the TPU component of EVA film in the pre-lamination The adhesive surface still has some stickiness, such as no need to immediately laminate, try to wait for 1 day before taking off the release paper, such as the need for secondary lamination within a short period of time, then avoid touching each other on the adhesive surface, do not fold placed.
Step 2: Bond one side of the material with hot melt adhesive to the other side of the material
After tearing off the release paper, the material can be second bonding, EVA film is still solid and does not have adhesive after cooling, the second lamination should also use heating equipment, the operating temperature at this time to be higher than the melting point of the material, so that the material is fully melted.
About the choice of pressing equipment for EVA film
Commonly used pressing equipment iron, flat ironing machine (manual pressure), flat compound machine (rewind principle) and roller compound machine, the above video equipment is the flat compound machine, generally speaking, family or small garment factory, the lamination demand is not very large use of iron and manual flat ironing machine can be operated, the price is also relatively cheap, such as the choice of iron, the best choice with temperature control industrial iron, so that it can be easy to control the operating temperature. This can be easy to control the operating temperature, of course, ordinary household iron is also possible, no matter which iron heating temperature can reach more than 160 °, but pay attention to, iron use try not to open the water vapor and water spray, which will lead to a decrease in the fastness of the rubber; lamination has a higher demand or conditions can choose the plate composite machine and roller composite machine, this equipment is larger, the cost is also higher, generally Prices range from a few thousand dollars to tens of thousands, hundreds of thousands.
Now that you have a good understanding of the use of EVA film, I wish you enjoy the beauty of EVA film in your application.
