发明名称 Flexible container with nonstick interior
摘要 A pouch suitable for packaging disposable consumer products having a pressure sensitive adhesive coated on a portion of a surface thereof. The pouch is formed from a silicone polymer coated paper with the silicone coating forming an internal surface of the pouch, thereby allowing easy removal of the product from the pouch and avoiding permanent sticking of the pressure sensitive adhesive coating to the pouch material. The silicone polymer coated paper used to form the pouch has, as a part of the composition thereof, a thermoplastic component which can be a thermoplastic basecoat, or an admixed thermoplastic polymer included in the silicone polymer coating, or a thermoplastic coating on the surface of the paper opposite the silicone coating, or combinations of these alternatives. In all cases, the thermoplastic component is provided in the form of a water-based emulsion or dispersion of a thermoplastic polymer, such as an emulsion of an ethylene vinyl acetate copolymer. The pouch is sealed along at least one edge where two layers of material are joined, the inward facing surface of at least one of the layers being silicone coated. The edge seal is formed by a process that provides simultaneous heating and embossing effects in the seal area.
