Product Description:
Flexible Packaging Aluminum Foil Another advantage of flexible packaging aluminum foil is that it is easy to carry and open, which is convenient for consumers to use. At the same time, flexible packaging aluminum foil can also print various patterns and characters, which can increase product aesthetics and brand value. In short, flexible packaging aluminum foil is a high-quality food and pharmaceutical packaging material, which has the advantages of airtightness, water resistance, corrosion resistance and light shading, which can protect the freshness and quality of products, and at the same time facilitate the use of consumers and increase the aesthetics of products. Alloys of flexible packaging aluminum foil The aluminum foil alloy grades selected for flexible packaging are mainly 1000 series and 8000 series. From the composition point of view, 1000 series contains more other alloy components than 8000 series. Therefore, in terms of the processability of aluminum foil for flexible packaging, the performance of 8000 series aluminum foil will be better. It is superior and has better processability than the 1000 series. Among them, 8011, 8021, and 8079 aluminum foils are the key products of the 8000 series aluminum foils. With their excellent sealing, plasticity, and corrosion resistance, they are widely used in food, beverages, and cigarettes. In the packaging of medicines, household products and other products.

Characteristics of flexible packaging aluminum foil Sealing: The crystal structure of metal provides high barrier properties. For example, aluminum foil has a thickness of 6.3~9µm and is usually used for compounding with materials such as film or paper to achieve better strength and sealing. Light shielding: Aluminum foil is a solid metal that can block visible light (including ultraviolet light). Stability: Except for acids and alkalis, it has high stability to most substances. Non-absorbent: Does not absorb lipids, oils, water and other liquids. Flexible Packaging Foil Hygiene and safety: After the entire production process of aluminum foil is completed, the finished aluminum foil has been sterilized and can be shipped in a sterile state. Aluminum foil is safe for food contact and will not cause bacterial growth. Food contact: European standard EN602 aluminum foil packaging can contact food, and western aluminum foil is usually used for packaging of food, medicine and cosmetics. Taste, Smell: Aluminum foil is a tasteless, odorless product. Recyclable: Aluminum can be recycled without compromising quality. Using modern separation technology, aluminum can be separated and utilized from daily necessities. Fully folded: After the aluminum is fully annealed, it returns to a fully soft state and can maintain a good shape after forming. Plasticity: Aluminum has very good plasticity and can produce large deformations without affecting its barrier properties. Corrosion resistance: In the natural state, aluminum will form an oxide film under the action of oxygen, which plays a good shielding role. Aluminum is also stable in the range of pH 4-9. Reflectivity: The reflectivity of radiant heat and light is 98%. The reflectivity of both sides of the aluminum foil is the same. Classification of aluminum foil for flexible packaging Flexible packaging aluminum foil mainly uses the metallic luster, light barrier, air barrier and certain strength and ductility of aluminum foil. According to different uses, the emphasized performance is also different. Aluminum foil for flexible packaging can be divided into three categories according to the use: The first category, food and drug packaging, is mainly sealed, mainly emphasizing gas barrier properties, light barrier properties, and non-toxicity. This kind of aluminum foil includes: packaging of medicines and quasi-drugs (medical equipment, medical supplies), 0.02MM, 0.015MM, 0.009MM, 0.007MM. Flexible Packaging Aluminum Foil Application Food, quasi-food (toothpaste) packaging, 0.015, 0.012, 0.009, 0.007MM. The second category, decoration, mainly focuses on aesthetics, emphasizing uniform surface gloss. This kind of aluminum foil includes: various printing outer packaging, advertising. The third category, between the first and second categories, requires both a certain degree of sealing and a certain degree of aesthetics. Mainly cigarettes, alcohol, food packaging. Common requirements for flexible packaging aluminum foil ● The common requirement for flexible packaging aluminum foil is a flat shape (less than 20Ⅰ); ● Uniform surface; ● Consistent thickness (3% tolerance); ● Good expandability (less than three meters); ● Clean surface; ● Fewer pinholes; ● Few but strong joints (less than 20%); ● Appropriate mechanical properties.
