How is the insulation effect of aluminum foil lunch boxes?
Functionality is the primary mission of packaging, and maintaining the taste and flavor of food is the core. In other words, the premise of packing meals is that the aroma of rice remains, but the delivery of takeaway meals takes at least 30 minutes and at most more than an hour, and the aroma of rice is easy to lose. This is also the reason why the takeaway experience has never been comparable to dine-in. Therefore, insulation has become the key to preserving aroma.
Aluminum foil lunch boxes are resistant to high temperatures (up to 200 degrees, melting point 600 degrees), oil-resistant, and have outstanding aroma-preserving performance.
Aluminum foil lunch boxes are also commonly used for paper-wrapped beverage packaging. The thickness of the aluminum foil in the packaging bag is only 6.5 microns. This thin aluminum layer can be waterproof, maintain freshness, and prevent bacteria and stains.
The properties of preserving fragrance and freshness make aluminum foil lunch boxes have the attributes of food packaging. The properties of high temperature resistance and good oil resistance allow it to easily handle various hot food types, even facing the long-standing problem of takeaway packaging - Chinese food with more oil and soup. It can be said that aluminum foil lunch boxes have natural takeaway attributes.
