GAS BARRIER FILM AND PACKAGING MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18648303 titled 'GAS BARRIER FILM AND PACKAGING MATERIAL
The gas barrier film described in the patent application consists of a substrate layer with a polypropylene resin, a resin layer with a copolymer of propylene and another monomer, an anchor coat layer with (meth) acrylic resin, and a vapor deposition layer of an inorganic oxide.
- The anchor coat layer has a thickness of 0.1 μm to 0.7 μm.
- The packaging material incorporating this gas barrier film also includes a sealant layer with a polypropylene resin.
Potential Applications: This technology can be used in the packaging industry for food packaging, pharmaceutical packaging, and other applications requiring gas barrier properties.
Problems Solved: The gas barrier film addresses the need for effective gas barrier properties in packaging materials to extend the shelf life of products and maintain their quality.
Benefits: The film provides excellent gas barrier properties, ensuring the freshness and quality of packaged products. It also offers improved durability and protection.
Commercial Applications: This gas barrier film can be utilized in various commercial sectors such as food packaging, pharmaceuticals, and electronics packaging, enhancing product protection and shelf life.
Questions about Gas Barrier Film: 1. How does the anchor coat layer contribute to the overall gas barrier properties of the film? The anchor coat layer with (meth) acrylic resin helps enhance adhesion and barrier properties of the film, ensuring effective gas barrier performance.
2. What are the potential environmental benefits of using this gas barrier film in packaging applications? The use of this film can potentially reduce food waste by extending the shelf life of products, leading to less spoilage and disposal.
Original Abstract Submitted
A gas barrier film includes: a substrate layer containing a polypropylene resin; a resin layer containing a copolymer of propylene and another monomer; an anchor coat layer; and a vapor deposition layer of an inorganic oxide, laminated in this order, wherein the anchor coat layer contains (meth) acrylic resin, and the anchor coat layer has a thickness of 0.1 μm to 0.7 μm. A packaging material includes the above gas barrier film, and a sealant layer containing a polypropylene resin.
