Double zero foil is usually between 0.0063mm and 0.0075mm thick. The thickness of this aluminum foil is measured in mm with two zeros after the decimal point, and is usually less than 0.0075 mm. Double zero aluminium foil is a type of aluminum foil with a thickness of less than 0.0075 mm, and is commonly used in the production of food packaging and pharmaceutical packaging, among other things. During the manufacturing process, the thickness of double zero aluminum foil is controlled to within two units of zero, i.e. one thousandth of a millimeter. This type of aluminum foil is lightweight, attractive, moisture-proof and corrosion-resistant, and also has good mechanical and processing properties to meet a variety of packaging and processing needs.
Double zero foil is usually made with advanced production processes and equipment, such as cold rolling, annealing, rolling and slitting, to ensure its quality and precision. In addition, Double zero aluminum foil also has better environmental performance and can be recycled to reduce pollution to the environment. Precision Rolling: After multi-pass roll rolling, the aluminum strip is gradually pressed into aluminum foil. This process involves multiple rolls rolling and milling to obtain aluminum foils of different specifications and sizes. In this process, precise rolls, roll path design and scientific rolling scheme are required to ensure the thickness, uniformity and surface flatness of the aluminum foil.
Double zero foil has a wide range of uses, including:
Packaging food:
It can be used to package a variety of foodstuffs, such as chocolate, candy, coffee, instant noodles, roasted meat and so on. It has excellent moisture-proof, oxidation-proof, odor-proof, heat insulation and heat preservation functions, which can effectively prolong the shelf life of food and maintain the taste, quality and nutrients of food.
Packaging drugs:
Double zero aluminum foil is also an important material for drug packaging, which can be used to package various drugs, nutrients and so on. In addition, double-zero aluminum foil can also be used in electrolytic capacitor materials, insulating materials for buildings, vehicles, ships, etc., as well as decorative gold and silver wires, wallpapers and other fields.
In short, double zero foil is a high-quality, high-precision, environmentally friendly packaging material, which is widely used in food, medicine, cosmetics and other fields.
