The M PET Sheet, or Metallized PET Sheet, is a polyethylene terephthalate material coated with a thin layer of metal, typically aluminum. This metallized layer enhances the sheet’s barrier properties, providing excellent protection against moisture, oxygen, and light. It is commonly used in packaging applications, such as food wraps, pouches, and labels, where preserving freshness and extending shelf life are essential. The M PET sheet is lightweight, flexible, and durable, offering a shiny, reflective appearance. Its heat-resistant and insulating properties make it ideal for a variety of industries, including food, electronics, and cosmetics. Recyclable and cost-effective, M PET sheets provide a high-performance, versatile packaging solution.
