Pressure-sensitive labels consist of face material + adhesive + release liner. Selection criteria:
1. Face Material
| Type | Characteristics & Applications | Food Industry Use Cases |
|---|---|---|
| Coated Paper | Low cost, high print quality; not water/oil-resistant | Dry foods (crackers, tea boxes) |
| Synthetic Paper | Water/oil-resistant, tear-resistant (e.g., PP, PE) | Frozen foods, beverage bottles |
| Film Materials | PET/PP: Temperature-resistant; PVC: Flexible (note eco-compliance) | Soy sauce bottles, chilled goods |
| Specialty Paper | Kraft paper: Natural texture; Food-grade laminated paper: Sealed against leakage | Organic foods, bakery packaging |
2. Adhesive
| Type | Properties | Applications |
|---|---|---|
| Permanent Adhesive | Strong bond; leaves residue upon removal | Glass jars/rigid packaging |
| Removable Adhesive | No residue; repositionable | Fresh produce/promotional tags |
| Freezer Adhesive | Maintains adhesion at -40°C | Frozen dumplings, ice cream |
| High-Temp Adhesive | Withstands steam sterilization (>100°C) | Canned/sterilized foods |
3. Release Liner
| Type | Properties |
|---|---|
| Glassine Liner | Thin, durable; ideal for high-speed labeling |
| Kraft Liner | Thick, rugged; suited for manual application |
| Transparent PET Liner | High clarity; used for visual-effects labels |
Key Factors for Selecting Pressure-Sensitive Labels
- Storage Conditions
- Frozen foods → Synthetic paper (PP) + Freezer adhesive
- Oily products (e.g., condiments) → PE film (barrier properties)
- Container Material
- Glass/metal → Permanent adhesive (high adhesion)
- Plastics → Test adhesive compatibility
- Printing Requirements
- High-resolution graphics → Coated paper/glossy PET
- Anti-counterfeiting needs → Specialty papers (e.g., thermochromic ink)
- Regulatory Compliance
- Direct food contact labels → Meet GB 4806 (China) / FDA (USA) / EU 10/2011 standards
- Migration testing for inks/adhesives
- Cost & Efficiency
- Mass production → Glassine liner (high-speed applicators)
- Short-term promotions → Removable adhesive
Industry Application Examples:
| Food Type | Recommended Label Material | Reason |
|---|---|---|
| Frozen Dumplings | PP synthetic paper + Freezer adhesive + Glassine liner | Cold/moisture resistance |
| Olive Oil (Glass) | Matte PET film + Permanent adhesive + Kraft liner | Oil resistance; premium appearance |
| Fresh Produce | Removable adhesive + Biodegradable paper | Residue-free removal; eco-friendly |
| Canned Foods | High-temp PET + Sterilization-resistant adhesive | Tolerates 121°C sterilization processes |
