Self-adhesive pdlc film electric opaque film
1.ESWITCH electric opaque film Structure And Principle
2.ESWITCH PDLC Film Properties
a.It adopts unique liquid crystal formula, the materials are attached closely, the transmittance is very high when it’s opened, the haze is very high when it’s closed. The privacy protection effect is superior.
b.Complete product size, besides 1.2 meters, 1.5 meters, 1.8 meters of regular width, can also customize special width up to 2.2m, and has multi-color optional: milky white, gray, tea brown color.
c.Our self-adhesive PDLC film has good flexibility, can be bent freely. Easy to realize design, and widely used.
d.The working temperature difference is very large, from severe cold temperature (above -20 °C) and high temperature (below 75 °C).
e.Low driving voltage and low power consumption during use.
f.PDLC has strong adhesion and long service life.
g.Scratch resistant layer, no scratch after paste. More easier to clean.
h.Superior production technology, strict production and quality control, ensure the stability and reliability of product quality.

Packaging Protection
ESWITHC PDLC Film is attached with protective film on double-sides. Customers need to remove the protective film before using the film product.
Packing
a.The adhesive smart film can be packaged in roll, roll the product on a 6-inch paper core and wrapped in cushioning material, use the carton packaging on the outside.
b.Identification: A product label is attached to the outside of the carton box to indicate the product name, model number, batch number, quantity, date, etc.
Storage Method
The film should be stored in a warehouse that is ventilated, dry, temperature -15 ° CC ~ 50 ° C, and relatively low temperature 85% RH, away from heat sources. Do not touch acid and alkali gases and liquids during storage.
