Product Description

MPA is a material based on BOPP substrate, with one side coated with acrylic for printability and heat sealing, and the other side coated with PVDC for high barrier and heat sealing properties. It is adaptable to various types of packaging equipment. This product is widely used, especially for vertical and horizontal packaging, serving as the outer layer packaging after being laminated with PE or CPP.

Key Features


  • The acrylic coating has a low and stable coefficient of friction, ensuring the coated film is highly adaptable to packaging machines.

  • The film boasts excellent transparency and glossiness.

  • It exhibits superior moisture and oxygen barrier properties, with perfect aroma and fragrance retention capabilities.




Important Notes


  • Offers good adaptability for vertical and horizontal packaging processes.                            

  • Ideal for dry lamination applications.

  • Capable of double-sided heat sealing, suitable for lap sealing and overlap sealing techniques.                             

  • The acrylic side is well-suited for water-based ink printing.                                    

  • The acrylic side requires pre-coating with adhesive for co-extrusion lamination.           

  • The PVDC side is suitable for lamination
