Embodiment Construction

[0010] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the present embodiment comprises inner layer 1, outer layer 3 and interlayer 2, inner layer 1 is glutinous rice paper, outer layer 3 is kraft paper, interlayer 2 is polypropylene or polyethylene laminating plastic woven bag, interlayer 2 and outer layer 3. Composite layer is formed by hot pressing, the inner layer 1 is an independent layer, and the composite layer is provided with a tear opening, and the tear opening is far away from the inner layer 1.

[0012] When opening the packaging bag, only need to open the tear opening from the composite layer, because the inner layer 1 is packaged with glutinous rice paper, and can be directly processed without opening the inner layer 1 in production.

[0013] The glutinous rice paper absorbs moisture, the outer layer 3 of kraft paper is moisture-proof and leak-p...

Abstract

The invention discloses a cement packing bag. The cement packing bag comprises an inner layer (1), an outer layer (3) and a sandwich (2), wherein the inner layer (1) is made from wafer paper, the outer layer (3) is made from Kraft paper, and the sandwich (2) is made from polypropylene or polyethylene laminated plastic woven bags. The packing bag can be used for effectively preventing moisture, dampness and rupture, is more suitable for long-distance transportation than woven bags and is not prone to leakage.

Description

technical field [0001] The invention relates to a cement packaging bag, which comprises an inner layer, an outer layer and an interlayer. Background technique [0002] Cement, powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. Using it to cement concrete made of crushed stones not only has higher strength after hardening , but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0003] At present, most of the cement in our country is packaged in woven bags, which is expensive, and the packaging materials will age after being used for many times, which will cause the cement to solidify due to moisture and pollute the environment. Contents of the invention [0004] ...
