Embodiment Construction

[0014] The composite plastic woven bag for fine powder products provided by the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 is a perspective view of the structure of the composite plastic woven bag for fine powder products provided by the present invention. As shown in FIG. 1 , the composite plastic woven bag 10 for fine powder products provided by the present invention is an ordinary composite plastic woven bag, the lower edge of which is covered by sealing paper 12 . That is, the sealing paper 12 is folded and pasted on the bottom edges of the front and rear sides of the composite plastic woven bag 10. One method of pasting the sealing paper 12 is to apply a layer of ordinary adhesive or latex on the surface of the sealing paper 12. , and then stick it on the bottom edge of the composite plastic woven bag 10 . The sealing paper 12 can also be pasted on the bottom edge of the composite plastic woven bag 10 after t...

Abstract

The invention relates to a composite plastic packaging pouch of powder product. Wherein, its bottom edge is treated with ultrasonic wave to form adhesive part; the upper part of adhesive part is stitched via stitch wire; the sealing paper via fused material or coated with liquid adhesive, or packed with emulsion coats the adhesive part and stitch wire. The inventive adhesive part can avoid powder leakage.

Description

technical field [0001] The invention relates to a composite plastic woven bag for packing various powdered fertilizers, cement and chemical products, etc., for fine powder products, in particular to a fine powder that can prevent the contents in the woven bag from leaking to the outside Composite plastic woven bags for products. Background technique [0002] Generally speaking, a composite plastic woven bag is a packaging bag used to package products other than grains, such as salt, sugar, cement, fertilizer, chemicals and PVC powder, usually composed of kraft paper surface and plastic woven cloth. Lining composition. Among them, the plastic woven fabric is made of polypropylene or polyethylene as the main raw material, and the raw silk with excellent tensile strength and uniform quality is made by the method of melting and stretching, and then the raw silk is woven by a knitting machine. The production process of the composite plastic woven bag is to use molten polypropyl...
