A Japanese company has developed an environmentally friendly packaging material - steel foil. When it is discarded and sent to a landfill, it can quickly rust and decompose and it will hardly pollute the surrounding environment.
The steel foil made of metal has a thickness of only 30 microns and is soft and delicate. Its elasticity and satin similar, while tough and wear-resistant. Using it to package foods such as candies and beverages can effectively prevent the invasion of microorganisms, insects and rodents, ensure the safety of foods and extend the shelf life.
