お弁当箱は食品包装業界に欠かせない包装箱です. 市販されている一般的な弁当箱の包装材には、プラスチック製の弁当箱が含まれます。, アルミホイルのお弁当箱, 等. その中で, アルミホイルのお弁当箱がよく使われています. お弁当の包装に, アルミ箔はバリア性に優れているため広く使用されています。, 柔軟性と軽さ.
The most suitable and common aluminum foil alloy is usually 3003 アルミ箔合金. アルミホイル 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% マンガン. This composition provides good strength and formability while maintaining high purity.
合金 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. アルミホイル 3003 provides a protective barrier against moisture, oxygen and other contaminants, 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.
アルミ箔は熱伝導性に優れています, 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, 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, 成形性, corrosion resistance and food safety properties. アルミホイル 3003 provides an effective barrier against external factors while maintaining the freshness and flavor of packaged foods.
