Barrier paper is a packaging material with special barrier properties, mainly used to prevent oxygen, moisture, grease, odour or other specific gases from passing through to maintain the quality and stability of the products inside the package. Barrier paper has the following features:

  1. High barrier properties: Barrier paper can significantly reduce the permeability of gases and water vapour 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 films, some types of barrier papers are more environmentally friendly, can meet the requirements of sustainable development, and are easy to recycle and degrade.
  3. Structural composites: Barrier papers are often designed with multi-layer structures, such as one or more layers of polymer or inorganic coatings on a paper substrate, or composites with high-barrier films such as EVOH (Ethylene Vinyl Alcohol Copolymer), to form a composite material that combines the flexibility of paper with excellent barrier properties.
  4. Processing adaptability: Barrier paper shows good processing performance in printing, slitting, folding, gluing, etc., and is suitable for various forms of packaging solutions.
