Easily Pull Aluminum Foil Sealing Pads (usually referring to aluminum foil sealing pads with a pull-tab design) are a common type of packaging sealing material, widely used for bottle sealing in industries such as food, pharmaceuticals, and cosmetics. The following is a detailed explanation of its usage and precautions:
---
### **1. Main Uses**
1. **Sealed Container**: Prevent air, moisture, and bacteria from entering, extending the product's shelf life.
2. **Anti-counterfeiting feature**: After tearing, there will be a noticeable residue, preventing re-use.
3. **Convenient Opening**: Easily tear open with the pull-tab design (pull-tab ear), no tools required.

### **二、使用方法**
1. **Installation Steps**：
- **Clean the bottle opening**: Ensure that the container opening is dry, free of oil or residue.
- **Placing the Gasket**: Place the aluminum foil gasket (with the shiny side facing out, and the matte side adhering to the bottle mouth) flat on the bottle mouth.
Hot-press sealing
- Heat the bottle mouth with a hot-sealing machine (adjust the temperature and time according to the equipment and the material of the gasket).
- If no specialized equipment is available, some gaskets can be manually pressed to adhere (please confirm the product instructions).
2. **Method of Activation**：
- Find the "pull tab" (pull ring or protruding part) at the edge of the gasket.
- Pinch the pull tab with your fingers and slowly pull it up, the aluminum foil will tear open with the tension.
- If the pull ring breaks, you can gently pry open the edge of the bottle opening with a small knife.

### **三、注意事项**
1. **Heat Seal Parameters**:
- Temperatures too high may burn through the aluminum foil, while temperatures too low may not seal properly. It is necessary to adjust the temperature according to the manufacturer's recommendations (common temperatures: 150-200°C).
- The hot pressing time is generally 1-3 seconds, which needs to be tested in combination with the material of the container.
2. **Applicable Containers**：
- Confirm that the container material (such as glass, plastic) is compatible with the aluminum foil gasket, and avoid high temperature deformation.
- The mouth of the bottle needs to be flat, without burrs or indentations, otherwise it will affect the sealing property.
3. **Storage Environment**：
- Unused gaskets should be stored in a cool and dry place to avoid moisture absorption or compression deformation.
- Sealed containers should be avoided from high temperatures or severe vibrations to prevent the failure of the seal.
4. **Safety Tip**：
- Be careful when tearing the aluminum foil as the edges may be sharp and cause cuts.
- After sealing food and medicines, it is necessary to check if they are completely closed to prevent contamination.

### **Section 4: Common Problem Solutions**
- **Ribbon Breakage**: Use a sharp knife tip to lightly pry the edge, or replace with higher-quality gaskets (increase thickness or strengthen the ribbon structure).
- **Sealing is not tight**：
- Check if the heat sealing temperature and pressure meet the standards.
- Confirm that the bottle opening matches the gasket size (the gasket diameter should be slightly larger than the bottle opening).
- **Residual Aluminum Foil**: Some of the pads are designed with a layered structure, and after tearing, there may be residual inner layers that need to be removed with a tool.

### **Example Scenarios**
- **Food**: Milk powder cans, seasoning bottles, coffee bottles.
- "**Personal Care**: Skin care products, perfume bottles, medicine bottles."
- **Industry**: Sealing of chemical container (requires corrosion-resistant material).

By following the above steps and precautions, it is possible to ensure that the easy-to-open aluminum foil gaskets are effectively sealed and easily accessible. If you encounter any special issues, it is recommended to contact the supplier for specific parameter support.
