The main materials of laser stickers include laser film, adhesive, and backing paper, etc.
Laser Film
The primary material of laser stickers is laser film, a special type of film with high reflectivity that exhibits unique metallic luster and colors, creating excellent visual effects. Laser films come in various materials, mainly PET, PVC, BOPP, and PC, etc. Different materials have distinct characteristics and application scenarios. For example:
- PET-based laser film features high transparency and tear resistance, suitable for application on transparent or glossy surfaces.
- PVC-based laser film is flexible, has a smooth surface, and adapts well to curved surfaces, making it ideal for sticking on bent surfaces.
Adhesive
Adhesive is another crucial material for laser stickers, used to bond the laser film and backing paper. The selection of adhesive significantly impacts the performance of laser stickers. Currently, there are two main types of adhesives on the market:
- Water-based Adhesive: Primarily used for indoor applications, it is non-volatile, odorless, and causes minimal environmental pollution.
- Oil-based Adhesive: Suitable for outdoor use, it is water-resistant, corrosion-resistant, and aging-resistant, ensuring the long-term performance of laser stickers in outdoor environments.
Backing Paper
Backing paper is the final key material of laser stickers, referring to the paper attached to the back of the laser film. Its functions include:
- Protecting the adhesive and laser film from contamination.
- Providing fixation to facilitate the cutting of laser stickers.
