Laser adhesive labels are a type of self-adhesive label material that form special optical patterns (such as holographic textures, rainbow effects, three-dimensional lighting) on the surface of the substrate through laser holographic technology. The core of these labels lies in using the principles of laser interference and diffraction to create micro-rough patterns on the surface of films or paper, which will display brilliant dynamic colors or three-dimensional visual effects when illuminated. They have both identification functions and anti-counterfeiting and decorative properties. Common substrates include PET (polyethylene terephthalate), BOPP (biaxially oriented polypropylene), and paper, with pressure-sensitive adhesive applied on the back, allowing them to be adhered to various object surfaces.
The core characteristics of laser adhesive labels
1. Unique optical decorative effects
Holographic dynamic vision: The surface patterns reflect and refract light in a directional manner, presenting color changes (such as rainbow gradients, flowing metallic luster) or three-dimensional patterns (such as three-dimensional text, embossed effect) when viewed from different angles. Their visual impact is far stronger than that of ordinary labels, quickly attracting attention.
Customized textures: Customizable exclusive laser patterns (such as brand logos, anti-counterfeiting patterns, special patterns) are available, with fine patterns that are difficult to replicate, combining decoration with brand recognition.
2. Outstanding anti-counterfeiting function
High technical threshold: The production of laser holographic patterns requires specialized equipment (such as holographic plate-making machines) and complex processes. Counterfeiters find it difficult to precisely replicate the texture details, making them particularly suitable for high-end products (such as tobacco, alcohol, cosmetics, luxury goods) for anti-counterfeiting labels.
Hidden anti-counterfeiting: Some products embed micro-sized text, invisible patterns, or special light-changing effects in the holographic textures. They can only be identified with specific tools (such as magnifying glasses, ultraviolet lamps), further enhancing the anti-counterfeiting level.
3. Appropriate substrate performance for diverse scenarios
Based on different substrates (PET, BOPP, paper), they can have corresponding characteristics:
PET substrate: Tolerant to tearing, temperature (-40°C to 120°C), waterproof and oil-resistant, suitable for outdoor, humid or frequently rubbed scenarios (such as beverage bottles, electronic products).
BOPP substrate: Good flexibility, moderate cost, suitable for food packaging, daily-use labels (such as snack bags, detergent bottles).
Paper substrate: Environmentally friendly and biodegradable, but has poor water resistance, suitable for short-term decorative scenarios such as gift boxes, handicrafts.
4. Adhesion and durability
The pressure-sensitive adhesive is stable in performance and can be selected as general adhesive (suitable for smooth surfaces), strong adhesive (rough surfaces), or removable adhesive (temporary sticking), making it less likely to fall off after application, and the initial adhesion is convenient for adjusting the position during labeling.
The weather resistance varies depending on the substrate: PET laser adhesive labels are resistant to ultraviolet rays and high/low temperatures, and are unlikely to fade in outdoor use; paper laser adhesive labels need to avoid humid environments to prevent substrate deformation.
5. Printing and processing adaptability
The surface can be compatible with various printing processes (such as screen printing, digital printing, hot stamping, UV printing), and when the laser texture and printed patterns are superimposed, a "holographic + color" composite effect can be formed (such as printing brand text on the holographic texture, with the text and background light and shadow coordinating).
Support for die-cutting processing, capable of being made into any shape (round, irregular, rounded rectangle, etc.), suitable for different packaging design requirements.
6. Environmental and safety
Main substrates (such as PET, BOPP) themselves are non-toxic, and products that comply with food contact standards can be used in scenarios where they directly come into contact with the human body (it is necessary to confirm whether the adhesive layer and ink are compliant).
Some paper laser adhesive labels are biodegradable, suitable for environmental packaging requirements.
