Barrier paper is a kind of packaging material with barrier coating or PE/PP/PET/PLA biodegradable material coating and special barrier performance, which is mainly used to prevent the transmission of oxygen, moisture, grease, odor or other specific gases to maintain the quality and stability of the products inside the package.

Biodegradable high barrier paper has the following features:

  1. High barrier: Barrier paper can significantly reduce the permeability of gases and water vapor through physical or chemical treatment, thus extending the shelf life of environmentally susceptible products such as food and pharmaceuticals.
  2. Environmentally friendly and recyclable: Compared with traditional plastic film, biodegradable high barrier paper is more environmentally friendly, can meet the requirements of sustainable development, easy to recycle and biodegradable.
  3. Structural Composite: Barrier papers are usually designed with a multi-layer structure, such as one or more layers of polymer or inorganic coatings on the paper substrate, or composite with high barrier biodegradable films such as PLA, forming a composite material with both paper flexibility and excellent barrier properties.
  4. Processing adaptability: Barrier papers show good processing performance in printing, slitting, folding, gluing, etc., and are suitable for various forms of packaging solutions.
