PRODUCT AND METHOD FOR A PLASTIC BAG OR PLASTIC COMPOSITION
COMPRISING INORGANIC MINERAL
Field of the Invention 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.
Background of the Invention Printed and unprinted 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.
The amount and type of resin used, and the thickness, material weight and density of the packaging materials all affect the cost and other characteristics of the Date recue / Date received 2021-12-15 plastic bags. Key performance attributes of these packaging materials include substantial barrier protection, product protection and containment, shipping, storage, and dispensing applications, 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, Polyethylene (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. Lin-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 clear 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 polychlorotrifluoroethylene (PCTFE or CTFE), which is a plastic material characterized by exceptional moisture and good oxygen barrier characteristics as well as good clarity.

2 WO 2017/106565 pcpus2016/067035 A problem that exists with prior films is that these products do not incorporate low cost, environmentally friendly materials and designs. Environmentally friendly materials can have desirable attributes such as biodegradability, compostability, and recyclability, and may also use less energy, pollute less, and generate fewer greenhouse gases in their manufacture than previous materials. Such environmentally friendly materials are increasingly in demand from consumers and retailers.
Another significant problem that exists with prior flexible film packaging is the high concentration of expensive plastic and polymers required to achieve the performance specifications needed. Yet another problem is the very expensive combinations of plastics, foils, coatings, and metalized films to achieve structural, barrier, sealing and printability aspects.
