Hologram stickers are typically made from a polyester film that is coated with a thin layer of aluminum or a similar reflective material. This coating creates the holographic effect by diffracting light and producing a three-dimensional image or pattern.
The polyester film used for hologram stickers is usually optically clear and provides stability and durability to the sticker. It is resistant to tearing, moisture, and UV radiation, making hologram stickers suitable for both indoor and outdoor applications.
The holographic layer on the sticker is created through a process called holography, which involves recording interference patterns of light. This results in a unique visual effect that changes with the angle of view, giving the sticker a distinctive and eye-catching appearance.
Hologram stickers are commonly used for security and authentication purposes, such as on product packaging, ID cards, passports, banknotes, and other items where counterfeiting or tampering needs to be deterred. The holographic nature of these stickers makes them difficult to replicate accurately, adding an extra layer of protection against forgery.
