Based on the technical requirements of Suzhou Lingyao's fully automatic self-adhesive labeling machines and the search results revealing common self-adhesive label types in industrial applications, here is a professional breakdown of label types, their pros/cons, and suitable products:
1. Coated Paper Labels
Core Characteristics:
- Material: Paper base with gloss/matte coating for ink absorption.
- Adhesive: General-purpose water-based acrylic adhesive.
Pros:
✅ Cost-Effective: Lowest material cost for high-volume printing.
✅ Print Quality: Sharp text/graphics with inkjet/laser printers.
✅ Eco-Friendly: Biodegradable paper base.
Cons:
❌ Low Durability: Not waterproof or oil-resistant; degrades in humid/chemical environments.
❌ Limited Flexibility: Prone to tearing on curved surfaces.
Ideal For:
- Pharmaceutical: Non-sterile secondary packaging (carton labels).
- Cosmetics: Product information tags on outer boxes.
- Logistics: Shipping labels for dry environments.
2. Synthetic Polymer Labels (PP/PET/PVC)
Core Characteristics:
- Material: Plastic films (Polypropylene, Polyester, PVC) with permanent adhesives.
- Surface: Waterproof, chemical-resistant.
Pros:
✅ Extreme Durability: Resists water, oils, solvents, and UV exposure .
✅ Conformability: Stretches to adhere tightly to curved containers (bottles, tubes).
✅ Temperature Resilience: Stable from -40°C to 150°C (PET).
Cons:
❌ Higher Cost: 2-3x more expensive than paper.
❌ Recycling Challenges: Non-biodegradable (requires specialized processing).
Ideal For:
- Medical Devices: Sterile instrument labels (autoclavable PET).
- Beauty Products: Waterproof labels for shampoo/serum bottles.
- Industrial Chemicals: Drum/tank labels exposed to harsh solvents.
3. Silver Foil & Metallized Labels
Core Characteristics:
- Material: Polyester film with aluminum layer + protective laminate.
- Adhesive: High-tack industrial adhesive.
Pros:
✅ Premium Aesthetics: Mirrored/chrome finish for luxury branding.
✅ Barrier Properties: Blocks oxygen/light, extending product shelf life.
✅ Tamper-Evidence: Delaminates if removed (security feature).
Cons:
❌ Print Limitations: Requires thermal transfer printing (no inkjet compatibility).
❌ Cost Premium: Highest material cost among common labels.
Ideal For:
- High-End Cosmetics: Perfume/skincare premium packaging.
- Electronics: Anti-static labels for circuit components.
- Pharma: Light-sensitive drug vials (e.g., retinoids).
4. Specialty Adhesive Labels
a) Freezer Labels
- Adhesive: Rubber-based glue adhering to frozen surfaces (-40°C).
- Use Case: Cryogenic storage (vaccines, biologics).
b) Removable Labels
- Adhesive: Low-tack adhesive for temporary marking.
- Use Case: Batch-coding trial products or reusable containers.
c) Medical PSA (Pressure-Sensitive Adhesive)
- Material: Hypoallergenic film + skin-safe adhesive.
- Use Case: Transdermal patches/wearable sensors.
