Aluminum Foil Self-Adhesive Seal Liner (20mm–120mm) for Aluminum Cans |

Our Aluminum Foil Self-Adhesive Seal Liner is designed specifically for aluminum cans and metal containers, providing a reliable tamper-evident seal without the need for induction sealing equipment. Available in diameters ranging from 20mm to 120mm, these pressure-sensitive seal liners adhere firmly to the container mouth after cap application, creating a secure barrier against moisture, oxygen, dust, and contamination.

Widely used in protein powder packaging, coffee cans, tea containers, nutritional supplements, health products, spices, and dry food packaging, this self-adhesive sealing solution helps manufacturers improve product freshness, extend shelf life, and enhance consumer confidence. The embossed aluminum foil surface offers a premium appearance while delivering excellent sealing performance for domestic and export packaging applications.

Many manufacturers using aluminum cans encounter several common issues:

Without an effective seal, moisture and oxygen can enter the package, causing product degradation, caking, flavor loss, or reduced shelf life.

Long-distance shipping and e-commerce logistics may result in powder leakage, product loss, and customer complaints.

Traditional induction sealing requires expensive sealing machines, maintenance costs, and additional production processes.

Consumers increasingly expect visible evidence that a package has not been opened before purchase.

International markets often require stronger package integrity and contamination protection during transportation.

The self-adhesive seal liner is inserted inside the container cap before application.

Place the seal liner into the cap.

Tighten the cap onto the aluminum can.

The pressure generated by the cap causes the adhesive layer to bond with the container opening.

When the consumer opens the container for the first time, the seal remains attached to the container mouth, providing visible tamper evidence.

This process eliminates the need for induction sealing equipment while maintaining effective package protection.

Choose a seal liner matching the internal diameter of the aluminum can opening. Available sizes range from 20mm to 120mm.

Best suited for:

• Protein powder
• Coffee powder
• Tea
