What is Mono-material package?
DNP Mono-material Package
Mono-material package is typically a PP or PE-based packaging that provides recyclability. DNP mono-material package further focuses on maintaining a variety of functions such as barrier, stiffness, sealability, heat-resistance, etc. In response to environmental issues such as marine plastic pollution or global warming, increasing number of sustainable packagings are being used around the world. Mono-material package is being focused, in order to realize a circular economy.
Why is it innovative?
Many flexible packagings for food and daily necessities are made from different materials with different properties to provide various functions such as preservation of contents and robustness of the packaging. On the other hand, flexible packagings made of multiple materials are difficult to be recycled since the separation to each material group is quite challenging by its nature. Mono-material package makes it easier to recycle and improve the quality of the post-recycled material.
One of the main challenges of making mono-material package is that the function of protecting the contents is diminished. By adding high barrier properties to PP or PE-based film using our unique converting technology, DNP Barrier Mono-material package can retain high level of oxygen and water vapor barrier properties without using aluminum foil, metalized PET film or PET-based transparent vapor deposition film. Transparent high barrier olefin structure is also currently under development.

How to design for recycling
As this packaging material is made of greater than 90% PP or PE, it is possible to conform to the Circular Economy for Flexible Packaging (CEFLEX) guidelines, which are published by a European consortium promoting the recycling economy in the flexible packaging industry.
