Embodiment 1

[0027] An anti-wrinkle film-coated woven bag is prepared by the following steps:

[0028] (1) The components of the raw materials are measured in parts by weight, and after mixing, they are dried at 90-100°C. The raw materials include polypropylene, modified filler masterbatch, and reinforcing agent; the polypropylene in the raw materials is molten Polypropylene with an index of 3g / 10min and an isotacticity of 94-96%, the modified filler masterbatch is calcium carbonate with a fineness of 400 mesh, and the reinforcing agent is a heat-resistant-dimensionally stable reinforced polypropylene masterbatch; step (1 ) The components of the raw materials are 100 parts of polypropylene, 40 parts of modified filler masterbatch and 15 parts of reinforcing agent in parts by weight.

[0029] (2) Put the dried raw materials into an extruder to extrude to form a film. The temperature of the feeding section of the extruder is controlled at 190~200°C, the temperature of the compression section...

Embodiment 2

[0038] The physical property test result of the flat wire and finished product that above-mentioned embodiment 1 method makes is as follows:

[0039]

[0040] This test proves that the finished product formed by the present invention has thin thickness and strong tensile properties.

Embodiment 3

[0042] Functional Results Test:

[0043] A kind of anti-wrinkle film-coated woven bag made by the method of the above embodiment 1 and the common woven bag fabric are carried out by a crease recovery performance tester to detect its crease recovery performance, and the comparison results are as follows,

[0044] Test items

Abstract

The invention discloses a wrinkle proof film laminated woven bag and relates to the technical field of plastic woven bags. All raw material components are mixed according to weight part ratio, and then are subject to drying treatment at the temperature of 90 to 100 DEG C; the raw materials comprise polypropylene, modified filling masterbatches and a reinforcing agent; in the raw materials, the polypropylene adopts the polypropylene with the melt index of 3g / 10min and the isotacticity of 94 to 96 percent, the modified filling masterbatches are made of calcium carbonate with the fineness of 400meshes, and the reinforcing agent adopts the special masterbatches used for increasing intensify and enhancing rigidity, which is heat-resistant and stable in dimension; the wrinkle proof film laminated woven bag has the advantages that the flat filament thickness is enven, the shrinkage ratio is low, warps and wefts in circular woven cloth are prevented from folding, marriages and chromatic aberration are avoided, the fastness in film lamination is excellent, a composite layer is even, bubbles and wrinkles are avoided, the entire thickness is small, and the tensile strength is strong.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to an anti-wrinkle film-coated woven bag. Background technique [0002] The application range of finished bags woven by polypropylene flat wire is becoming wider and wider, such as parasols, various travel bags, travel bags, logistics packaging bags, etc., not only meet the requirements of their use in terms of physical properties, but also require bright, smooth appearance, It is light and handy, giving people an aesthetic feeling in perspective, but the existing polypropylene flat wire woven bag is easy to form wrinkles, resulting in unsightly appearance. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a wrinkle-resistant film-coated woven bag, the thickness of the flat thread is uniform, the shrinkage rate is small, the warp and weft threads of the circular weaving cloth are not discount...
