India's new technology to replace metal cans with multilayer films

The use of multi-layer membranes instead of canned foods by a food company in India has not only reduced the cost of packaging, but also preserved the anti-corrosion effect. The multi-layer film is a composite of three layers of polyester film, aluminum film and polypropylene film. It is used for food packaging. It can not only ensure the strength of flexible packaging cans, but also prevent light leakage and oxidation. According to reports, sardines are packed in multi-layer films and their shelf life is more than two years.
