7 micron aluminum foil refers to aluminum foil products with a thickness of 7 microns (0.007 mm), characterized by its thinness, lightness, and flexibility. Aluminum foil is widely used in food packaging, cooking, preservation, heat insulation, and electronic products, among other fields. Due to its excellent barrier properties, light weight, and malleability, 7 micron aluminium foil performs well in these applications.
Specifications of 7 micron aluminum foil:
– Common alloys:
Primarily 1235, 8079, and 8011 aluminum alloys. Among them, 1235 aluminum foil has good corrosion resistance, while 8079 alloy aluminum foil has high strength and excellent heat-sealing performance.
– Common Specifications:
Width is generally between 50mm and 1730mm, with inner diameters of 76mm and 152mm, and thickness tolerance is typically ±2%.
Performance characteristics of 7 micron aluminum foil:
– Strong barrier properties:
Despite its ultra-thin thickness, it effectively blocks oxygen, moisture, grease, and light, effectively maintaining the freshness and quality of the contents and extending shelf life.
– Good flexibility:
It possesses excellent flexibility and ductility, allowing for easy bending and folding without easily breaking, making it suitable for various complex packaging and forming processes.
– High Strength:
Taking 8079 aluminum foil as an example, its strength can reach 150N-250N, 30%-50% higher than ordinary aluminum foil, providing a certain degree of protection for the contents from external damage.
– Excellent printability:
Its smooth and flat surface effectively absorbs ink, enabling clear and vibrant printing results through various printing methods such as flexographic and screen printing. The printed patterns are also resistant to fading and peeling.
– Environmentally friendly and recyclable:
Made from recyclable aluminum materials, it can be completely recycled and reused after use, contributing to resource conservation and environmental protection.
Applications of 7 micron aluminium foil:
– Food packaging:
Suitable for candy wrapping paper, baking trays, snack bags, fresh meat and frozen food packaging, effectively maintaining the flavor and freshness of food.
– Pharmaceutical packaging:
Commonly used in blister packaging for pharmaceuticals, it blocks light, moisture, and oxygen, protecting the stability and efficacy of the medicine and ensuring it exerts its optimal effect within its shelf life.
– Battery manufacturing:
A commonly used current collector material in the production of lithium-ion and lead-acid batteries, it facilitates the conduction and collection of electrons within the battery.
– Electronics:
Can be used to manufacture electromagnetic shielding materials for electronic devices, effectively blocking electromagnetic interference and ensuring the normal operation of electronic equipment.
– Other applications:
It can also be used to manufacture thermal insulation materials, sunshade materials, and emergency thermal blankets, utilizing its thermal insulation and reflective properties to provide heat preservation and insulation.
