14micron alu alu foil is a laminate consisting of aluminum foil, polyethylene and PVC film layers. Aluminium – The barrier properties of aluminum foil are critical for applications that require protection against moisture, lys, oxygen and other external factors.

14 micron aluminum foil refers to the thickness of the aluminum layer within the laminate. Thinner aluminum layers provide flexibility and cost savings, while thicker aluminum layers provide better barrier properties.

The barrier properties of 14 micron aluminum foil can be summarized as follows:

1. **Aluminum foil is moisture-proof**: Aluminum foil is impermeable to moisture and is an excellent barrier against moisture and water vapor. This feature helps maintain the integrity and quality of aluminum foil packaging products.

2. **Oxygen Barrier**: 14mic aluminum foil provides an effective oxygen barrier to prevent oxidation and spoilage of sensitive products such as medicines and food.

3. **Light Barrier**: 14mic aluminum foil reflects light and UV radiation, protecting photosensitive products from degradation and maintaining their quality over time.

4. **Aroma Barrier**: 14mic aluminum foil prevents volatile compounds from escaping, helping to preserve the aroma and flavor of packaged products.

5. **Thermal Insulation Layer**: 14mic aluminum foil has good thermal insulation properties and helps maintain the temperature of the packaged products.

6. **Mechanical Protection**: Aluminum The aluminum layer in aluminum foil adds strength and puncture resistance, protecting the contents from physical damage during handling and transportation.

Overall, 14 micron aluminum foil offers a variety of barrier properties, making it suitable for packaging sensitive products that need protection from moisture, oksygen, light and other environmental factors.
