Introduction to the Structure and Function of Adhesive Label Materials
surface material
Universal label materials: paper, PVC, PET, PP, etc
PMMA anti-counterfeiting label
aluminum foil label
Special label PI, etc
Product Category
• Roll material
• Sheet material
• Surface coating
Surface coating: improves adhesion with ink Surface material: provides temperature and chemical resistance
Adhesive: Ensure a strong bond between the label and the substrate
Lining paper: prevents adhesion and facilitates die-cutting
Printing method
• Needle injection
• Heat transfer printing
• Laser etching
• Digital printing
• Inkjet printing
Screen printing
Common adhesives/surface materials and their characteristics for labels
Adhesive low surface energy plastics, such as polyethylene and polypropylene
• Bonding rough surfaces
• Adhesive to oily surfaces
• High temperature resistance
• Adhesive paint or smooth surface
• Adhesive high surface energy plastics
Show evidence of tampering without leaving any residue
Excellent UV resistance performance
Polyester: The most commonly used surface material for PET
- Durability
- Available in matte/bright white or silver
- There are anti-counterfeiting products available (Void)
Soft PVC:
- Good adhesion to clothing
- Good weather resistance
- There are anti-counterfeiting products (fragile paper)
Acrylic esters:
- High temperature resistance
- Adverse operating environment
Kimdura polyolefin/synthetic paper
- Universal type
- Low cost
• Polyimide: PI
- High temperature resistance
Aluminum foil:
- High temperature resistance
- Solvent resistant
