3004 Food Grade Aluminum Foil for Food Container
3004 aluminum foil is one of the commonly used raw materials for aluminum foil container. It is of food grade. What requirements should 3004 food grade aluminum foil should meet? Learn more.
Aluminum foil containers have long been one of the most efficient and cost-effective ways to package food in takeout and pre-packaged applications. These containers can be used at a wide range of temperatures and are suitable for a variety of food processing applications, improving the freshness and shelf life of food without absorbing water or grease. Consumers can complete a series of steps such as cooking, freezing, transportation and supply in simple, safe and convenient aluminum foil packaging.
3004 aluminum foil is one of the commonly used raw materials for aluminum foil container. The aluminum foil tray produced by 3004 alloy not only ensures high cost performance but also the high strength. It can be said that it combines the price advantage of 8011 and the strength advantage of 3003.
3004 alloy is an aluminum alloy with manganese as the main element. It is an aluminum alloy that cannot be strengthened by heat treatment. It has high plasticity, excellent formability, good welding performance, higher strength than 1xxx aluminum alloys and corrosion resistance is close to 1xxx aluminum alloys.
There are high standards for the food container aluminum foil. These standards stipulate the requirements for the physical properties, chemical composition, surface quality and food contact safety of food-grade aluminum foil to ensure that food packaged in aluminum foil meets national health standards and food safety requirements.
The physical properties of food-grade aluminum foil include thickness, strength, elongation and surface flatness. These indicators can be measured and inspected through standard instruments and equipment to ensure that the physical properties of the aluminum foil meet the standard requirements.
The chemical composition of food-grade aluminum foil is also one of the important contents of inspection. Common chemical components include aluminum content, alumina content, impurities and harmful substances, etc. Through chemical analysis, we can check whether the chemical composition of aluminum foil meets the standard requirements to ensure the quality and safety of aluminum foil.
Surface quality is also one of the important aspects of food-grade aluminum foil inspection. Surface quality not only directly affects the food quality and appearance of aluminum foil packaging, but is also closely related to the hygiene and safety of food. For food-grade aluminum foil, its surface should be flat and smooth, without cracks, pitting, pollution and other defects to ensure the packaging effect of the aluminum foil and the safety of food.
The food contact safety of food-grade aluminum foil is also a focus of inspection. As a food packaging material, aluminum foil is of greatest concern to consumers as to whether harmful substances will migrate when it comes into contact with food. Through the detection and analysis of migrating substances after aluminum foil comes into contact with food, it can be ensured that the food contact safety performance of aluminum foil meets standard requirements.
