Hemaokang Steel (Shandong) Co., Ltd. is a professional manufacturer and supplier of high-quality aluminum coils. Established in 2025, we have quickly grown to generate an annual export value of US$50 million – US$100 million, serving clients across North America, South America, Europe, Southeast Asia, Africa, and beyond. Our 1235 Aluminum Coil in O Temper is specifically engineered for flexible packaging and food contact applications, combining superior cleanliness, precise thickness control, and excellent formability. This product meets stringent hygiene standards and offers reliable performance for printing, lamination, and conversion processes.
The 1235 alloy is widely recognized for its high purity (minimum 99.35% aluminum) and exceptional ductility after O temper annealing. This makes it the ideal choice for producing thin-gauge aluminum foil used in food wrappers, pharmaceutical blister packs, and flexible pouches. With our advanced production lines and strict quality management system certified under ISO9001:2015, every coil is inspected to ensure consistent mechanical properties and surface finish.
Product Features & Benefits
- High Purity & Food Safety: 1235 alloy contains minimal heavy metals, ensuring compliance with food contact regulations. The O temper provides a clean, non-toxic surface suitable for direct contact with food.
- Excellent Formability: The fully annealed (O temper) state offers extreme softness and flexibility, allowing the coil to be rolled into ultra-thin foils (down to 0.006mm) without cracking or tearing.
- Consistent Thickness Tolerance: Our advanced rolling mills maintain thickness variations within ±5% of nominal value, critical for uniform coating and printing in flexible packaging.
- Superior Surface Quality: The coil surface is free of oil stains, scratches, and pinholes, ensuring high-quality lamination and barrier properties.
- Customizable Dimensions: Available in widths from 200mm to 1600mm, inner diameters 76mm or 152mm, and thicknesses from 0.006mm to 0.2mm to meet specific production requirements.
- Reliable Packaging: Each coil is packed with moisture-proof paper, plastic film, and wooden pallets to prevent damage during long-distance sea freight from Qingdao port.

Our 1235 Aluminum Coil O Temper is extensively tested in-house for pinhole count, oil residue, and adhesion properties. The product is ideal for subsequent coating, printing, or lamination processes used in the production of flexible packaging films, food containers, cigarette packaging, and pharmaceutical blister foils. The O temper ensures that the material can be easily shaped around products without spring-back, reducing waste and improving production efficiency.
