Aluminum foil for food containers has become a core material for modern packaging due to its ultra-high barrier properties, thermal conductivity, environmental friendliness, recyclability and food safety. In this article, in addition to introducing the well-known manufacturer HTMM(Henan Tendeli Metallurgical Materials Co., Ltd) from Henan, China, we will discuss the uses of aluminum foil for food containers, the reasons for adopting 3003 H24 Aluminum Foil 50 Micron, as well as the specifications used in different markets, the production process, quality control, and product packaging.
Aluminum foil for food containers is irreplaceable in food preservation, high-temperature cooking, and low-temperature freezing scenarios. It is a "container" for holding, heating, transporting and displaying food products, as well as a "multifunctional film" that extends shelf life, reduces energy consumption and enhances the brand experience. From home ovens to 10,000 meters in the air, from street takeaways to cold chain supermarkets, aluminum foil food containers cover almost all the scenarios that require "hot chain" or "cold chain", such as instant food containers, baking molds, aseptic liquid packages, frozen food trays and so on.
Generally speaking, aluminum foil for food containers is made of alloys 8011 or 3003, with thicknesses between 0.03 mm and 0.2 mm, widths between 200 mm and 1,300 mm, in H22 or H24 tempers. The inner diameter of the foil is 76 mm or 152 mm, and the outer diameter between 450 mm and 600 mm, or can be customized on request.
Our recommendation of 3003 H24 0.05mm aluminum foil for food containers is based on its excellent all-round properties.3003 aluminum alloy is an Al-Mn rust-resistant aluminum alloy with good formability and moderate strength, and in the semi-hard state (H24), its plasticity is moderate, allowing it to meet the complex stamping and forming requirements of food containers while maintaining sufficient stiffness and compression resistance. Its strong corrosion resistance can effectively resist the acid and alkali substances in food, to ensure the freshness and safety of food. The 50-micron layer within the container enhances structural integrity and formability while optimizing material expenditure, delivering balanced flexibility and tear resistance to accommodate diverse food packaging requirements. In addition, It also meets food-grade safety standards, such as FDA and EU regulations, and can be used in direct contact with food. At the same time, the recyclability of the aluminum foil meets the requirements of environmental protection and sustainable development. As a result, this specification of aluminum foil has become an ideal material for manufacturing food containers, which are widely used in various scenarios such as airline lunch boxes, takeaway lunch boxes, and home baking trays.
Aluminum foil for food containers varies from market to market depending on local regulations, eating habits and costs. The North American market tends to have a thickness of 45-55 microns, in compliance with FDA standards, while the EU market has a thickness of 48-52 microns, in compliance with EU 10/2011 and LFGB regulations. The Southeast Asian market, on the other hand, prefers low-cost aluminum foils with a thickness of 38-45 microns. These differences in specifications across markets reflect the diverse needs for aluminum foil for food containers in terms of strength, flexibility, corrosion resistance, and cost-effectiveness.
At GNEE, we control the quality of our raw materials to ensure that we produce aluminum foils that are brighter, softer, and more pliable. By rigorously inspecting the finished product, we reduce the number of joints in a single roll of foil, thereby increasing your productivity. GNEE Group maintains an established presence as a recognized foil stock provider for aluminum container manufacturing. In addition, our aluminum foil for containers can be pre-coated with food-grade lubricant before leaving the factory so that customers can use it directly in the production of stamping equipment to improve yield.
In addition, our production process strictly follows international advanced standards. The production process begins with the melting of high-purity aluminum ingots and high-quality manganese alloys, ensuring the purity of the liquid aluminum through precise composition control and refining processes. Subsequently, advanced casting and rolling technology is used to cast and roll the liquid aluminum into 7 mm thick slabs, which are then gradually thinned to 0.6 mm through multiple passes of cold rolling. After cold rolling, the aluminum foil enters the intermediate annealing process, through precise temperature control, so that the aluminum foil obtains good recrystallization organization and improves its ductility and toughness. After annealing, the aluminum foil enters the foil rolling mill again and undergoes several passes of precision rolling, and is finally rolled into an ultra-thin aluminum foil of 50 microns. During the foil rolling process, an advanced online thickness detection system is used to monitor the thickness of the foil in real time to ensure that the thickness tolerance is within ±3%. In the concluding stage, the foil undergoes precision slitting and rewinding, producing industry-compliant coils primed for QA protocols. The entire production process strictly follows the ISO 9001 quality management system to ensure that each batch of products meets high quality standards.
Our company adopts advanced testing equipment such as Germany's RAYONIC thickness gauge, Siemens shape meter and Honeywell thickness gauge, as well as physical and chemical testing equipment such as American MA950 spectrometer, Japanese universal testing machine and crystal microscope, ensuring the accuracy and reliability of test results. Starting from the procurement of raw materials, the company conducts strict tests on the composition of aluminum ingots and manganese alloys to ensure that they meet national standards and industry requirements. During the melting process, a spectrum analyzer is used to test the composition of each furnace of aluminum liquid to ensure the accuracy of the alloy composition. Slabs after casting and rolling are tested by ultrasonic flaw detection to exclude internal defects. During cold rolling and foil rolling, X-ray thickness gauge is used to monitor the thickness of aluminum foil in real time to achieve thickness uniformity. The finished aluminum foil undergoes strict physical property tests, including tensile strength, elongation, cup ting value, etc., to ensure that its mechanical properties meet the 3003 H24 standard. In terms of food safety, the company regularly sends samples to third-party testing organizations for safety testing of food contact materials to ensure that the products comply with international standards such as FDA SVHC and EU ROHS. Through these strict quality control measures, GNEE ensures that each batch of aluminum foil products meets the high quality requirements of our customers.
