جعبه های ناهار از جعبه های بسته بندی ضروری در صنعت بسته بندی مواد غذایی هستند. مواد معمول بسته بندی جعبه ناهار در بازار شامل جعبه های ناهار پلاستیکی است, جعبه های ناهار فویل آلومینیومی, و غیره. در میان آنها, جعبه های ناهار فویل آلومینیومی بیشتر مورد استفاده قرار می گیرند. برای بسته بندی جعبه ناهار, فویل آلومینیومی به دلیل خواص مانع عالی آن به طور گسترده ای مورد استفاده قرار می گیرد, انعطاف پذیری و سبکی.
The most suitable and common aluminum foil alloy is usually 3003 آلیاژ فویل آلومینیوم. ورقه ی آلومینیومی 3003 has many performance advantages in lunch box packaging.
3003 aluminum alloy contains manganese as its main alloying element, with a typical composition of approximately 98% aluminum and 1-1.5% منگنز. This composition provides good strength and formability while maintaining high purity.
آلیاژ 3003 provides sufficient strength for packaging applications while maintaining a high degree of formability. 3003 foil can be easily formed and folded to package food, making it ideal for lunchbox packaging.
Manganese is added to the 3003 alloy to enhance its corrosion resistance, making it suitable for contact with food and not harmful to the human body. ورقه ی آلومینیومی 3003 provides a protective barrier against moisture, اکسیژن و سایر آلاینده ها, helping to maintain the freshness and quality of packaged foods.
Aluminum foil made from 3003 alloy typically has a bright, shiny surface finish, which enhances the visual appeal of the aluminum foil lunch box and makes it suitable for branding and labeling purposes.
According to food safety regulations, aluminum foil made of 3003 alloy is considered safe for contact with food. It does not react with acidic or alkaline foods, ensuring that the taste and quality of packaged foods are not affected.
Aluminum foil has excellent thermal conductivity, allowing it to evenly distribute heat when cooking or reheating food inside the lunch box. This feature helps maintain the desired temperature of food for a longer period of time.
فویل آلومینیومی بسیار قابل بازیافت است, and alloy 3003 is no exception. It can be easily collected, recycled and reused, making it an environmentally friendly choice for packaging materials.
3003 aluminum alloy has become the first choice for lunch box packaging due to its combination of strength, شکل پذیری, corrosion resistance and food safety properties. ورقه ی آلومینیومی 3003 provides an effective barrier against external factors while maintaining the freshness and flavor of packaged foods.
