도시락은 식품 포장 산업에서 필수적인 포장 상자입니다.. 시중에서 흔히 볼 수 있는 도시락 포장재에는 플라스틱 도시락이 포함됩니다., 알루미늄 호일 도시락, 등. 그 중, 알루미늄 호일 도시락이 더 일반적으로 사용됩니다.. 도시락 포장용, 알루미늄 호일은 우수한 차단 특성으로 인해 널리 사용됩니다., 유연성과 가벼움.
The most suitable and common aluminum foil alloy is usually 3003 알루미늄 호일 합금. 알루미늄 호일 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% manganese. This composition provides good strength and formability while maintaining high purity.
합금 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. 알루미늄 호일 3003 provides a protective barrier against moisture, 산소 및 기타 오염물질, 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.
Aluminum foil is highly recyclable, and alloy 3003 is no exception. It can be easily collected, 재활용 및 재사용, 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, 성형성, corrosion resistance and food safety properties. 알루미늄 호일 3003 provides an effective barrier against external factors while maintaining the freshness and flavor of packaged foods.
