Is metal box environmentally friendly?

The answer is affirmative. The production of metal sheet boxes usually does not involve harmful substances such as formaldehyde and glue, which avoids the pollution problem caused by the release of formaldehyde from traditional boards due to glue, and also conforms to modern environmental protection concepts.

The environmental friendliness of metal plate boxes (commonly made of steel and aluminum) is mainly reflected in their "sustainability" and "low pollution residue", which are the key advantages over plastic boxes and wooden boxes
 

Metal materials have high hardness and strong impact resistance, and can be used for 5-10 years (or even longer) under normal maintenance, far exceeding plastic boxes (1-3 years) and wooden boxes (susceptible to moisture/insect damage, with fewer repeated uses).

1. Metal is currently one of the most mature and highly recyclable materials in human recycling technology
2. The steel recycling rate exceeds 90%, and the aluminum recycling rate exceeds 85%, and no toxic or harmful substances are produced during the recycling process (compared to plastic recycling which easily releases microplastics and chemical additives, wood recycling may be accompanied by preservative pollution);

Metal box production does not require the addition of plastic plasticizers or wooden box preservatives (such as formaldehyde and phenol), and does not release toxic gases or dissolve harmful substances during use. It is particularly suitable for scenarios such as food and medicine that require high levels of "pollution-free packaging", avoiding problems of plastic microplastic pollution and penetration of wooden preservatives.
