Container aluminum foil refers to thin aluminum metal foil used to make disposable or reusable lunch boxes, containers and packaging materials. This kind of aluminum foil is usually made of higher purity aluminum alloy through continuous rolling processing.
Container aluminum foil has excellent barrier properties (preventing the penetration of oxygen and moisture), high temperature and low temperature resistance, and no harmful substances are precipitated during the heating process, so it is especially suitable for the food packaging industry.
Aluminum foil containers are widely used in catering takeout, airline catering, home cooking (such as baking, barbecue) and other fields due to their lightweight, hygienic, good thermal insulation effect, environmental protection and recyclability.
According to different usage needs, aluminum foil containers can be designed in various shapes and sizes, and can be a single layer of aluminum foil or a multi-layer structure made of other materials to meet the functional requirements of different food packaging.
Aluminum foil for containers usually uses several specific aluminum alloys. These alloys are widely used to make disposable or recyclable meals due to their excellent processing properties, corrosion resistance, hygienic safety and suitability for food contact. box. The following are several commonly used aluminum foil alloys:
Different types of aluminum foil are selected based on specific container uses, cost considerations, and product performance requirements. Among them, 8011 and 3003 may be relatively cost-effective choices, while 8006 and 5052 may be more suitable for high-end or special requirements application scenarios.
coated aluminum foil
The thickness of container aluminum foil is generally between 0.006mm and 0.20mm. It can be divided into wrinkled and wrinkle-free, and can also be divided into disposable and reusable.
Container aluminum foil is actually made of 3000 series or 8000 series aluminum ingots as raw materials, which are cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor.
Aluminum foil containers are widely used in aviation food, home cooking and large chain cake shops. Main uses: food cooking, baking, freezing, preservation, etc.
Container aluminum foil is usually made of 8011, 8006 aluminum alloy or 3003, 3004 aluminum alloy, and there are two types: plain foil and coated foil.
Barrier performance Aluminum foil for containers has good barrier properties and can effectively block air, water vapor and odors, ensuring the freshness and taste of food. At the same time, aluminum foil also has functions such as moisture-proof, mildew-proof and rust-proof, which can extend the shelf life of food.
Processing performance Aluminum foil for containers has good processing performance and can meet the needs of various processing techniques. For example, aluminum foil can be punched, bent, welded and other processes to facilitate the production of containers of various shapes and structures. In addition, aluminum foil can also be compounded with other materials to improve the overall performance of the packaging.
Safety performance Aluminum foil for containers is a non-toxic, odorless metal material that will not contaminate or cause odor to food. At the same time, aluminum foil can still maintain good stability and safety in extreme environments such as high temperature and low temperature, and will not release harmful substances.
Thickened aluminum foil containers are different from traditional aluminum foil boxes and are increasingly favored by the takeout market.
Thickened aluminum foil containers are also called wrinkle-free aluminum foil containers, scientifically known as aviation containers, commonly known as golden aluminum foil containers, and golden aluminum foil take-out packaging boxes. It adopts multi-layer aluminum ingot drawing technology and is stamped in one step. It has the characteristics of high strength, no heavy metal residue, and can be environmentally friendly and recycled;
As take-out packaging boxes and pre-made vegetable packaging boxes, they generally need to be sealed with corresponding sealing machines.
The sealing film is also made of aluminum foil, which can effectively ensure the overall beauty and strength requirements of the lunch box. Of course, if some meals do not contain soup, or for the convenience of displaying the contents of the dishes, matching plastic lids can also be used for sealing.
The golden aluminum foil lunch box has beautiful material and is convenient for box type customization and printing.
At the same time, it has excellent heat preservation function, which can effectively protect the color and taste of dishes. Solve the problem of reduced food quality caused by plastic lunch boxes in many restaurants;
The sealing feature is also a major feature of golden aluminum foil lunch boxes that is different from traditional lunch boxes such as plastic lunch boxes, traditional aluminum foil lunch boxes, paper lunch boxes, etc. Sealing can effectively prevent leakage
The golden aluminum foil lunch box can be heated by open flame, electric ceramic stove, oven, microwave, etc.;
