In the aluminum foil product system, 8011 O soft aluminum foil is a versatile core category that balances formability, barrier properties, and economy. It is also one of the aluminum foil varieties with the highest export volume at Haomei Aluminum. As a technician who has long followed up on product formulation and customer application debugging, I firmly believe that the core value of o soft 8011 aluminum foil lies in maximizing the material’s plasticity and adaptability through a precise recrystallization annealing process. This allows it to deeply match the diverse processing needs of the food, pharmaceutical, and composite packaging industries, making it a high-tolerance and widely adaptable basic material in industrial production lines.
In terms of specifications and core performance, Haomei soft 8011 aluminum foil covers a thickness range of 0.015mm to 0.20mm, with customizable widths ranging from 100-1700mm. The maximum diameter of a finished roll is 1200mm, and the maximum weight per roll can reach 2500kg, making it suitable for large-scale slitting and deep processing production lines. In terms of performance, after sufficient recrystallization annealing, the finished product exhibits a stable tensile strength of 85-105 MPa, an elongation at break ≥22%, and a cupping test value ≥7.5 mm. Compared to the hard 8011 aluminum foil product, its plasticity is improved by more than three times, and it is less prone to edge cracking and wrinkling during deep drawing. Regarding surface quality, the pinhole rate is controlled below 0.2 pins/m², both sides are smooth and free of oil stains, and the surface wetting tension is ≥32 mN/m, allowing for direct coating, printing, and lamination. Its resistance to oxygen, water vapor, and light is close to 100%, fully meeting the core requirements for sealed and preserved food applications. Hygiene indicators comply with FDA 21 CFR and EU 1935/2004 food contact material standards, and heavy metal leaching is far below the limits.
The excellent plasticity and comprehensive performance make soft 8011 aluminum foil the preferred substrate for many downstream industries, with application depth far exceeding that of ordinary aluminum foil.
In the food packaging and container industry, it is a core material for disposable aluminum foil food containers, egg tart holders, and yogurt sealing films. After deep drawing, the cup walls are uniform and free from springback deformation, and it can withstand a temperature range from -40℃ freezing to 200℃ baking, making it suitable for fully automated stamping production lines. Our catering packaging customers exporting to Europe, America, and Southeast Asia mostly choose 0.03-0.08mm thick soft 8011 aluminium foil for food container production, with a stable yield rate of over 98%, far exceeding the industry average.
In the pharmaceutical packaging industry, 0.02-0.03mm thick soft 8011 aluminum foil is the mainstream base foil for PTP pharmaceutical blister packaging. When laminated with PVC and PVDC, it offers excellent sealing performance, effectively isolating moisture and light, extending the shelf life of medicines. It also possesses easily puncturable characteristics for convenient patient access, and the product has passed pharmaceutical packaging material certifications in multiple countries.
In the field of flexible composite packaging, soft 8011 aluminium foil, when laminated with films such as PET and PE, can be used to create vacuum packaging bags for snacks, condiments, and pet food, significantly extending product shelf life. It is also widely used in building insulation layers and appliance insulation pads, with its easy bending and bonding characteristics greatly reducing on-site construction difficulties.
To ensure the uniformity of the o soft temper aluminum foil’s performance, we use an air-cushion continuous annealing furnace for finished product processing, with furnace temperature control accuracy reaching ±1℃, ensuring consistent hardness throughout the roll and eliminating unevenness. The entire production process is equipped with X-ray thickness gauges and an online surface defect detection system, ensuring thickness tolerance is consistently within ±2%, and batch consistency of key performance parameters (CpK ≥ 1.67). For export customers, we offer vacuum-sealed, moisture-proof five-layer protective packaging suitable for ocean shipping environments. We can also adjust the elongation and surface tension according to the customer’s stamping dies and laminating equipment parameters, reducing customer debugging costs.
As a manufacturer with over a decade of experience in aluminum foil exports, our soft 8011 aluminum foil has been supplied to nearly a thousand customers in more than 40 countries and regions worldwide. Compared to industry-standard products, we place greater emphasis on the precise matching of material properties with downstream processes. Through customized process adjustments, we help customers improve yield rates and reduce overall operating costs.
