Common materials used for general-purpose labels include:
1. **Paper**: The most widely used material, paper labels are cost-effective and suitable for indoor applications. They can be coated or uncoated, with options for gloss, matte, or semi-gloss finishes.
2. **Polypropylene (PP)**: Known for its durability and resistance to water, oil, and chemicals, PP labels are ideal for products that require a longer lifespan or exposure to harsh conditions.
3. **Polyethylene (PE)**: Flexible and resistant to moisture and chemicals, PE labels are often used for squeezable containers and products that require a high degree of flexibility.
4. **Polyester (PET)**: Highly durable and resistant to tearing, heat, and chemicals, PET labels are suitable for industrial applications and outdoor use.
5. **Vinyl**: Known for its durability and weather resistance, vinyl labels are often used for outdoor applications, including bumper stickers and signage.
6. **Thermal Paper**: Used for direct thermal printing, these labels are heat-sensitive and suitable for short-term applications like shipping labels and receipts.
7. **Foil**: Metallic foil labels offer a premium look and are often used for branding and decorative purposes. They can be made from aluminum or other metals.
8. **Fabric**: Used for clothing and textiles, fabric labels are made from materials like cotton, satin, or nylon, providing durability and comfort.
9. **Adhesives**: Labels can have permanent, removable, or repositionable adhesives, depending on the application requirements.
10. **Laminates and Coatings**: To enhance durability and appearance, labels may be laminated or coated with UV-resistant, waterproof, or scratch-resistant materials.
These materials are selected based on factors like the intended use, environmental conditions, and cost considerations.
