Aluminum foil adhesive is a kind of adhesive material with characteristics such as high-temperature resistance, moisture resistance, corrosion resistance, etc. It is often used in food packaging, electronic component labels, industrial identification and other scenes. The following are its usage method and precautions:
---
### **Step 1: Usage Procedure
1. Surface cleaning
- Ensure that the surface to be pasted is dry, flat, and free of oil or dust.
- Wipe the surface with alcohol or a neutral cleaner, and wait for it to completely dry before pasting.
2. **Cutting Aluminum Foil Tape**
- Cut the aluminum foil adhesive label to the appropriate size according to the requirement, and it is recommended to reserve a little extra margin at the edge.
3. **Peeling off the backing paper**
- Slowly tear the backing paper (release paper) from the corners, avoiding excessive force to prevent the adhesive surface from deforming.
4. **Adhering and Pressing**
- Adhere the aluminum foil adhesive side to the target location, press lightly from the center to the periphery to discharge air bubbles.
- Press the edge repeatedly with a scraping tool, roller, or fingers to ensure a complete fit.
5. Curing Time
- After pasting and allowing to stand for 24 hours, the adhesive will achieve its best adhesive strength (the specific time will depend on the environmental temperature and the type of glue).

### **二、注意事项**
1. Temperature Control
- The recommended environment temperature for pasting is between 10℃ to 35℃. Low temperature may cause the adhesive strength to decrease, and high temperature may soften the adhesive layer.
- If you need to resist high temperatures (such as oven labels), choose special high-temperature aluminum foil adhesive labels.
2. **Pressure and Speed**
- Adjust the label machine pressure during industrial labeling to avoid creasing or displacement of the aluminum foil.
- Manual labeling requires slow operation to reduce the formation of air bubbles.
3. **Special Surface Treatment**
- Rough surfaces (such as sandblasted materials) require the application of a primer to enhance adhesion.
- Curved surfaces must be adhered in different regions to avoid stretching the aluminum foil and causing cracks.

### **Section Three: Common Problem Solutions**
- "Insufficient Adhesion": Check if the surface is clean, or replace with a stronger adhesive type (e.g., strong acrylic adhesive).
- **Edge Curling**: Press lightly after heating with a hot air gun (temperature not exceeding the aluminum foil tolerance).
- **Residual glue stains**: Use alcohol or professional glue remover to remove.

### **Storage Suggestions**
- Unused aluminum foil adhesive labels should be sealed and stored to avoid direct sunlight and high-temperature and high-humidity environments.
- Storage temperature should be between 10℃ and 25℃, to prevent adhesive aging.

### **Example of Application Scenarios**
1. **Food Packaging**: Sealing labels for high-temperature steaming bags.
2. **Electronics Industry**: Anti-static labels for circuit boards and insulating labels for components.
3. **Industrial Identification**: Equipment nameplates, pipe corrosion-resistant labels.
