Embodiment Construction

[0013] An environmentally friendly chemical woven bag, consisting of an outer layer, a middle layer and a base layer, the outer layer is a pearlescent film layer, the middle layer is a polyethylene layer, and the base layer is made of warp and weft threads made of polypropylene , its preparation method is as follows:

[0014] 1) After drawing polypropylene to make 10mm warp and weft, each take 36 interspersed weaves to form the base layer;

[0015] 2) Use conventional adhesives and conventional gluing methods in this industry. After gluing, compound with pearlescent film layer and polyethylene layer on a compound machine, and the oven temperature is 300°C;

[0016] 3) Enter the cooling box for cooling and forming to obtain finished products.

[0017] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be pointed out that we can make various equivalent changes and modifications to the above-mentioned embodim...

Abstract

The present invention discloses an environmentally-friendly chemical woven bag comprising an outer layer, a middle layer and a base layer, the outer layer is a pearlised film layer, the middle layer is a polyethylene layer, and the base layer is prepared by alternately weaving warp and weft prepared from polypropylene. The present invention also discloses a preparation method of the environmental chemical woven bag. The environmental chemical woven bag has good waterproof and anti-corrosion properties, is clean in appearance, and three-dimensional, has UV resistance and high and low temperature resistance, and can replace paper-plastic bags for long-term storage of chemical products.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to an environmentally friendly chemical woven bag, and also relates to a preparation method of the environmentally friendly chemical woven bag. Background technique [0002] Woven bags are widely used, mainly used for holding and packaging various items, especially in industry. The raw materials for making woven bags are generally various chemical plastic materials such as polyethylene and polypropylene, which are extruded and stretched into flat wires, and then weaved, braided, and bag-made. At present, the materials for making woven bags are easily deteriorated, damaged, and poorly packed under conditions such as exposure to sunlight and humidity. Long-term preservation, and because it cannot be reused, it will bring a certain degree of pollution to the environment. [0003] Pearlescent film is made of polypropylene resin, adding calcium carbonate and pearlescent p...
