Mono-material Packaging Films

What Is Mono-material Packaging?

Mono-material packaging refers to packaging structures made from a single polymer family, such as polypropylene (PP), low-density polyethylene (LDPE), high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), or polyethylene terephthalate (PET). These recyclable packaging films are designed for easy sorting and reprocessing, making them ideal for the circular economy.
