Abstract

The invention provides a manufacturing method for a package bag which utilizes plastic bags in daily lives in the manufacturing process. Polypropylene (PP) plastic material is extruded through an extruding machine to form liquid film which is cooled and shaped in a water cooling chamber. A blade set cuts the shaped PP bars into PP slices having predetermined widths. In addition, the PP slices is evened, extended, and curved to form a barrel for further using. A bag weaving machine weaves the PP slices into PP weaved layers having predetermined widths and integrated with a bi-axial oriented PP film, and curved to a barrel. The method further includes introducing a folding mechanism to recess sewing the PP weaved layers to form a bag having a PP unit hollow bag, its bottom and a predetermined width.

Description

201016555 VIII. Description of the invention: [Technical field to which the invention pertains] The present invention provides a method for manufacturing a package, which is mainly for the manufacture of an environmentally-friendly bag for use in various types of articles, or for the usual shopping. The ρρ woven layer formed by PP (Polypropylene Polypropylene) plastic is combined with a biaxially stretched polypropylene film XBi-axial 〇riented PolyPr〇pylene,: pp). The leg is in the unit of hollow size of the required size, so that the button has good water penetration characteristics for use. [Prior Art] According to the current bag for wrapping various objects/or the bag for daily shopping, the manufacturing method is quite large; the bag for wrapping is the required volume of the outer kraft paper. Wide-width seams, which are combined in a kraft paper bag--transfer layer with Weidu hollow bubble distribution to form the 'objects in the packaged turn-over bag (4) to avoid the external f-face tearing, or the water infiltrating the object; The other environmentally-friendly bag body is a sacrificial material that is cut and positioned to be sewn into a preset shape.
