Laminated Glass with EVA Film

Laminated Glass with EVA Film

Laminated Glass with EVA Film is much important  one in the series of laminated glass in glass industry .The processing principle of EVA laminated glass is  similar to most of the laminated glass . Furthermore, using EVA film to laminating glass does not require autoclave. All laminating processing will be finished and completed in one vacuum laminator.  EVA Film for glass has excellent transparency, outstanding adhesion and aging-resistance (more than 20 years), can be used for architectural glass, decorative glass with fabric.

EVA film:

EVA stands for ethylene vinyl acetate, a copolymer resin used in the production of laminated glass as the interlayer sandwiched between two pieces of glass. The main function of the interlayer is to hold the two piece of glass together, thus making them safer and more secure. EVA film is translucent and has a light pattern on the surface before heating. After heating, it becomes completely transparent, offering good visibility. In the production of laminated glass with EVA interlayer, no autoclave, roller press, air bag, or vacuum rubber ring is required. As EVA interlayer can be handled under normal climatic conditions, no clean room with climatic control is required.

EVA Film is made out of macromolecule material and it performs excellent in bonding strength, heat resistance, cold resistance, humidity resistance and tensile strength in laminated. It has been partly taking the places of PVB film in laminated safety glass, laminated art glass, laminated color glass.

Advantages of EVA film :

– High tensile strength

– Excellent transparency

– Outstanding adhesion

– UV protection

– High wind resistance

– Good temperature withstanding

– Water proof

– Humidity durable

– Long-term reliable

– Sound barrier

EVA Gilm for Safety Glass:

  1. Extremely high transparency .The transmittance rate can reach 92.1%.
  2. Outstanding heat, humidity and ultraviolet ray durability and long-tem reliability
  3. Superior low moisture ingression than PVB, can fit for side-naked processing in high humidity environment.
  4. Widely use in more fields than other internal EVA films, which only laminate silk and films with glass.
  5. Highest interlayer laminating strength and security characteristics can avoid ungluing and air bubble caused by low-quality film.
  6. Superb compatibility with polymers and other insert media, such as PET,PC ,PVC, glass, wood cloth, paper liquid crystal sheet, solar cell ,etc
  7. Easy handling, using low-cost small vacuum-kiln equipment.
  8. Highest productivity, low waste.

-In the processing of EVA laminated glass, owing the ordinary glass with its green color, it will influence the original design effect.  However, using ultra-clear glass can have a excellent performance, it can make the interlayer fabric more clear.

-Processing Procedure Notes

1.)  Activate vacuum pump for 2-3min till the vacuum value reach 0.095Mpa, then start heating.

2.)The temperatures and times for processing based on 1Pc 5mm Glass +1Layer EVA Film + 1Pc 5mm Glass

3.)For thicker glass or more layers of EVA Film, the heat-holding-time should be longer, please check with “The Processing Parameter of Different Glass Thickness and EVA Film Layers” or consult us.

CNC-SC 60℃ 15-20min 130-145℃ 50-60min ≤75℃ ≤50℃





65℃ 15-20min 105-115℃ 40-50min ≤75℃ ≤50℃


1.) The plainness of the glass is poor (especially the tempered glass). Make sure the inserted film is thicker than the deformation scale of the two overlapping glasses.

2.) The film has not completely melted. Please raise the temperature or increase the time of heat-holding!

3.) Stop the vacuum pump two early. Don’t stop the vacuum pump until the temperature bellows 50℃.

4.) The Silicon Bag is leaking. Please replace the Silicon Bag to unsure that the vacuum value reaches 0.095Mpa.


Please fully confirm the corrosive and permeability of the edge sealing reagent and glass glue before using, for those may lead to films breaking away from glasses!
