Society’s perception and opinion about single-use plastic packaging is evolving and as a result, the demand for packaging that has a clear sustainability value is increasing, marking a trend of innovation in the application of these materials.


Our team is dedicated to finding viable solutions for a transition from conventional plastics to more circular materials, such as compostable bioplastics. We are currently innovating in various applications such as:


  • E-commerce packaging
  • Resins and films for high speed food wrapping
  • Higher renewable content resins and films
  • High barrier resins and films
  • Pallet and bundle wrapping films


The norms and laws of various countries are changing to promote compostable materials and their disposal. This drives the businesses, distributors and consumers of bags to migrate to these sustainable products. Some examples of regulatory standards that countries have adopted to support the shift to compostable bioplastics are: 


    • US Standard ASTM D6400 
    • Australian Standard – AS 4736 
    • European Norm: EN 13432 
    • Mexican Norm NMX-E-NYCE-273-2019 
    • Chilean legislation  Ley  21.100 
    • Colombian legislation  PL-2019-0724
