Aluminum foil sealing gasket (also known as induction sealing gasket) is a sealing component composed of aluminum foil, cardboard, PE/PP and other materials, widely used in industries such as food, medicine, cosmetics, etc. It tightly adheres to the container mouth through electromagnetic induction heating, forming a reliable sealing layer to ensure product leakage prevention, moisture resistance, and freshness preservation. 

Next, let's introduce some real application cases of aluminum foil sealing gaskets:

1. Liquid dairy product packaging (such as yogurt, fresh milk)

Application scenario: Sealing of bottle mouths for yogurt cups and fresh milk bottles

Function: Prevent oxygen from entering and extend shelf life

Prevent leakage during transportation

Adopting an easy to tear design, convenient for consumers to open

2. Seasoning packaging (such as soy sauce, vinegar, edible oil)

Application scenarios: Glass or plastic bottles for soy sauce, vinegar, edible oil, etc

effect:

Prevent liquid leakage and evaporation

Block air and prevent oxidation and deterioration

High end products use anti-counterfeiting aluminum foil gaskets to prevent counterfeiting

3. Instant coffee/milk powder packaging

Application scenarios: Metal or plastic cans for powdered foods such as coffee and milk powder

effect:

Moisture proof, anti caking, keep the powder dry

Prevent aroma volatilization and maintain flavor

Using tearable aluminum foil film for easy access

4. Packaging of drugs and health products

Application scenario: Sealing of medicine bottles and health product bottles

effect:

Prevent drugs from getting damp and oxidized

Ensure a sterile environment and comply with GMP standards

Some drugs are designed to prevent children from opening (such as press and rotate bottle caps+aluminum foil pads)

5. Cosmetics and daily chemical products (such as skin care products and perfume)

Application scenario: packaging of essence liquid, perfume, face cream, etc

effect:

Prevent liquid evaporation or contamination

Enhance the high-end feel of the product

Some brands use induction aluminum foil gaskets to enhance sealing performance

Aluminum foil sealing gaskets are widely used in various industries such as food, medicine, cosmetics, etc. due to their excellent sealing, moisture resistance, and freshness preservation properties. In the future, with the advancement of material technology, aluminum foil sealing gaskets will play a greater role in intelligent packaging, such as temperature control sensing and anti-counterfeiting traceability.
