The
painted color aluminum sheet for ropp caps has a varnish layer on the surface, thus it’s more expensive than mill finished ropp cap aluminum sheets. Generally the price is between $3000 to $4000 per metric ton. Grades for the sheet cover 1000, 3000, 5000 and 8000 series, with 1060, 3104, 3003 and 8011 the most popular. Up to specific uses of the bottle caps, the painted color aluminum sheet is made into varied tempers, such as H14, H16, H18, H19 and so on. Thickness of the sheet ranges from 0.012mm to 0.5mm, and the maximum width reaches 1600mm. All painted color aluminum sheets are hard, with a hardness between H14 and H24, tensile strength between 110 and 320, and elongation generally not less than 4. In China the most popular materials of aluminum anti-theft bottle caps are mainly 3003-H16 and 8011-H14 aluminum strip or sheet, with a 0.20-0.23mm thickness, and a 449mm-796mm width. In addition to H14 and H16, the temper of H18 is also available, too.
The ropp cap painted color aluminum sheet of Haomei follows strict technical and production rules to meet surface and mechanical standards of bottle cap materials. The surface is flat, free from roll marks, scratches, dents and stains, and the finished sheet must meet levels in elongation, tensile strength and strength. In addition, the sheet must go through bottle making test and reach relative technical rates. High-quality aluminum alloy bottle cap materials are widely processed into bottle caps for various beverages, wines, medicines and health care, cosmetics, snacks and other products. They have good sealing effects and meet the special requirements of high-temperature cooking and sterilization, and are well received by the market.
