What are the advantages of aluminium foil lunch boxes

1. Heat preservation and aroma retention

Aluminium foil lunch boxes are often used as paper packaging for drinks. The thickness of the aluminium foil in the bag is just 6.5 microns, a thin layer that is water resistant, fresh tasting, anti-bacterial and stain resistant. The aroma and freshness of the aluminium foil box makes it a food packaging property.

2. Harmless to the human body

Food safety is not only reflected in the food itself, but also in the food containers that come into contact with it. When disposable foamed plastic tableware is filled with hot food or boiling water at temperatures above 65 degrees, the toxic substances contained in the tableware can easily infiltrate the food, and if the concentration of such harmful substances exceeds the standard, the poison will be even greater. The main material of the aluminium foil lunch box is aluminium foil, which has a dense oxide layer on its surface. The chemical properties of this oxide layer are relatively stable, and aluminium ions will not be precipitated as long as it is not in a strong acid environment.

3. Environmentally friendly

The composition of aluminium foil lunch boxes is aluminium, which has a high recycling rate of up to 25 times and meets national food hygiene standards. Compared to the geological changes caused by white pollution, aluminium lunch boxes can be weathered in two to three years in the soil and will not cause any lasting damage to the land or change the nature of the implant.

4. Ductility and greater packaging surface area

Aluminium has a physical property, namely ductility, compared to other metals, using the same quality of aluminium can be processed to produce a larger surface area, packaging more things.
