Having cultivated the aluminum foil export industry for eight years, I firmly believe that the core competitiveness of export products lies not only in upholding professional standards but also in addressing the actual pain points in customer production. Our pre-lubricated aluminum foil for food containers is an iterative product developed based on the stringent requirements of the global food packaging industry and feedback from thousands of overseas clients. It balances the core demand for food-grade safety with significantly improved production efficiency for downstream enterprises, making it a core competitive advantage in the export market.
As an exporter, the most frequent question from overseas clients is: What is the pre-lubricating oil? Is it safe? This is also our primary consideration in product development. The pre-lubricating grease we use is a custom-designed food-grade DOS lubricant, strictly compliant with US FDA 21 CFR 178.3910(a) standards and NSF H1 certification, while also meeting the requirements of Chinese GB4806.9-2016 and EU REACH regulations, with full traceability of raw materials. Unlike traditional industrial lubricants, this food-grade DOS oil is colorless, transparent, odorless, and non-toxic. Even under high-temperature molding or food contact conditions, it will not leach harmful substances or affect the flavor of food. Based on years of export experience, we have abandoned animal oil-based lubrication solutions that are prone to residue and spoilage. This DOS oil combines excellent volatility and lubricity, leaving no noticeable oil residue after stamping and requiring no additional cleaning. This reduces production costs for customers and easily passes food packaging compliance tests in various countries.
Many customers wonder why pre-lubrication is necessary when ordinary aluminum foil can be used to make food containers. This is precisely our core optimization based on industry experience. Having been in the export business for many years, we have found that ordinary aluminum foil for containers lacks sufficient surface smoothness. During high-speed stamping, the friction between the foil and the mold is high, easily leading to surface scratches, wrinkles, and even cracks. This not only reduces product yield but also accelerates mold wear, increasing production losses and maintenance costs for customers. Pre-lubrication is like putting a “protective coat” on the aluminum foil. Through electrostatic spraying, food-grade grease is evenly adhered to the aluminum foil surface, significantly reducing friction during stamping, ensuring neat container forming and a smooth surface. It also improves demolding efficiency and adapts to automated production lines. This is a key reason why our products have gained recognition from large overseas food packaging companies.
In terms of specifications and applications, we fully adapt to the needs of different global markets, creating a diversified specification system. Our core specifications use two commonly used aluminum alloys, 8011 and 3003, with thicknesses ranging from 0.04mm to 0.08mm and widths from 400mm to 800mm. Thickness tolerances are controlled within ±3%. We can customize narrow, wide, and special thickness specifications according to customer needs to adapt to the production of food containers of different sizes. In terms of applications, tailored to overseas market demands, this pre-lubricated aluminum foil is widely used in various disposable food containers, including takeout containers, baking trays, airline catering boxes, barbecue tin boxes, and pre-prepared food packaging. It boasts advantages such as high-temperature resistance, corrosion resistance, and strong barrier properties, adaptable to high and low temperature environments ranging from -18℃ to 200℃. It can be used for refrigeration and preservation, as well as direct placement in ovens and open flame heating, perfectly meeting the needs of the overseas catering and food processing industries.
With 20 years of experience in the export market, we have always adhered to the principles of “compliance first, customer foremost.” This pre-lubricated aluminum foil is not only a reflection of our professional capabilities but also a deep understanding of industry needs. We understand that exported products are not just goods, but also a representation of trust. From the selection of food-grade oils and the optimization of the pre-lubrication process to the customized specifications, every step undergoes rigorous testing. In the future, we will continue to combine global market compliance requirements with customer feedback to continuously optimize product performance, providing overseas customers with more competitive and worry-free food container aluminum foil solutions, helping them expand into global markets.
