Aluminum foil liner(Aluminium foil liner) is a composite packaging material that combines the properties of paper and metallic aluminum foil, and is mainly composed of a multi-layer structure, including a base paper layer, an adhesive layer, and a thin aluminum foil layer in the middle. This material has a wide range of applications in the packaging industry, especially in food, tobacco, and pharmaceuticals. It forms a packaging liner with high strength and high barrier properties by laminating aluminum foil with specific types of paper.
Features
- excellent barrier property: the aluminum foil layer has high barrier property to water vapor, oxygen and other gases, which can effectively prevent the contents from moisture deterioration or oxidation and prolong the shelf life of the products.
- Good heat sealing and printing suitability: Aluminum foil liner can be heat sealed in various ways to ensure good sealing of the package; at the same time, its smooth surface is suitable for high-quality printing process, and it can print complex patterns, text information and anti-counterfeiting markings.
- environmental characteristics: despite the metal content, modern aluminum foil liner paper in the design and production process and strive to meet the requirements of green environmental protection, such as the use of recyclable materials, and can be discarded under certain conditions to achieve resource recycling and reuse.
- Excellent mechanical properties: Due to the composite structure, aluminum foil liner has high tensile strength and stiffness, especially suitable for high-speed operation on automatic packaging lines, and is not easy to break and deform.
Applications
Aluminum foil liner is widely used in many fields:
- Tobacco industry: as an important part of cigarette packaging, it is used in the inner packaging of cigarettes to protect the quality of cigarettes, provide moisture-proof and anti-counterfeiting functions, and enhance the brand image.
- Food Packaging: For candy, chocolate, bakery products and other types of food packaging, aluminum foil liner can ensure the freshness and flavor of the food and prevent the oxidation of fats and oils and loss of aroma.
- Pharmaceutical and healthcare products: For pharmaceuticals, healthcare products and other products that require strict control of environmental conditions, aluminum foil liners provide the necessary protective barrier to ensure product quality and safety.
- Packaging of other high-end consumer goods: in the packaging of cosmetics, alcohol and other commodities, aluminum foil liner is used to enhance the packaging grade and anti-counterfeiting effect due to its beauty and unique texture.
