Characteristics of cast-rolled easy-open lid material 8011-H18 aluminum foil

  • 1. It can effectively protect food from external influences, extend the shelf life of food, and facilitate users to open and close the packaging.
  • 2. The surface of the easy-open cover can be printed with various exquisite icons and text to enhance the appearance of the product and increase its appeal.

Why is the easy-open lid material made of cast-rolled 8011-H18 aluminum foil?

  • 1. Strength and hardness: Cast-rolled 8011-H18 aluminum foil has excellent strength and hardness properties, which allows the easy-open lid to withstand greater tension and pressure during use, ensuring the sealing and stability of the packaging.
  • 2. Corrosion resistance: 8011 aluminum alloy itself has good corrosion resistance and can effectively prevent acidic or alkaline substances in food or beverages from eroding packaging, thereby maintaining the quality and safety of food.
  • 3. Processing performance: Cast-rolled 8011-H18 aluminum foil has good processing performance and can be processed into easy-open lids of various shapes and sizes through stamping, stretching and other processes, which is suitable for packaging needs of different types and specifications.
  • 4. Excellent sealing performance: Easy-open lid materials need to have good sealing performance to ensure that the food or beverages in the package will not leak or be contaminated. 8011-H18 aluminum foil has excellent sealing performance, which can effectively prevent the penetration of oxygen, water vapor and other external substances, thereby extending the shelf life of food and beverages.
  • 5. Hygiene and safety: As a food-grade material, 8011-H18 aluminum foil meets hygienic standards and will not cause pollution to packaged food or beverages, so it is widely used in easy-open lid materials.
  • 6. Recyclability: Aluminum foil is a sustainable material that can be recycled and reused, helping to reduce resource consumption and environmental pollution. Easy-open lids are usually single-use packaging, and the recyclability of 8011-H18 aluminum foil makes it an ideal choice for environmentally friendly packaging.
  • 7. Cost-effectiveness: 8011 aluminum alloy is a commonly used aluminum alloy material with relatively low cost, which can meet the needs of mass production and provide cost-effective packaging solutions.
