Definitions

  • PRODUCT AMD METHOD FOR A PLASTIC BAG OR PLASTIC COM PQSITIQH
  • the present invention relates to products and a method of producing products which comprise polyethylene and inorganic minerals for a single layer plastic bag or plastic composition.
  • Printed and imprinted flexible and semi-rigid packaging materials are commonly used for packing retail, industrial, and commercial products into plastic bags such as T- sacks, sacks, pouches, wrappers and the like. Desired product features of plastic bags include printability and different levels of opacity. Since some plastic products may be used in a sterile environment, sterilization may also be a required step in the manufacturing process.
  • Barrier protection refers to the ability of a packaging material to stop or retard the passage of atmospheric gases or water vapor into the material from the outside environment.
  • the prior art uses metalizing to provide a lustrous metallic appearance, that when applied to plastic film, improves gas and light barrier properties of the film.
  • PE film has been used in the prior art on preparation of bags because of its transparency, toughness, heat seal-ability, low water vapor transmission rate, low temperature performance and low cost. PE films are highly permeable to oxygen and other non-polar gases and have high viscoelastic flow properties.
  • Polypropylene (PP) film is a transparent, tough, thermoplastic film. Un-oriented film is soft and becomes brittle at low temperature, however this property as well as strength, stiffness, and clarity can be improved by orientation e.g. bi-axially oriented polypropylene (BOPP), Polystyrene film Is a transparent, stiff film of high permeability and moderate temperature resistance that can be oriented to improve strength, Films can also be made of polyamide (PA), PA is used almost entirely as a film or sheet material in packaging applications. The dear film offers a good oxygen barrier, and is particularly tough and abrasion resistant. However, PA film is a poor moisture barrier, does not heat seal, and has cost disadvantages. Films can also be made of
