preparation example Construction

[0116] The second aspect of the present invention provides a method for preparing a thermally spliced ​​container bag, which includes at least the following steps:

[0117] 1) Woven fabric: the base fabric is woven with warp and weft, and the warp to weft ratio of the base fabric is 1: (0.7~1.2);

[0118] 2) Coating: using a double-sided coating process, in step 1) the base fabric is coated with a composite film of PE and PP on both sides to obtain a finished fabric;

[0119] 3) Forming: The finished fabric obtained in step 2) is cut, and heat-sealed, spliced, and formed to obtain.

[0120] The present invention has no special restrictions on the preparation method of the warp and weft in step 1), as long as the required warp and weft can be obtained without affecting the purpose of the present invention. For example, the preparation method of warp and weft may be: extruding the raw materials for preparing the warp and weft into a film, then cutting and slitting, and finally stretchin...

Abstract

The invention relates to flexible freight containers, in particular to a thermal splicing type flexible freight container. The thermal splicing type flexible freight container comprises a flexible freight container body 1, and a feeding port 2 and a discharging port 3 are formed in the middle of the top and in the middle of the bottom of the flexible freight container body 1 separately; the four top corners of the flexible freight container body 1 are each provided with a reinforced sling 4, and the triangular junctions of the flexible freight container body 1 are each provided with a sealed triangular module 5; and the flexible freight container body 1 comprises a waterproof layer 6, a base cloth layer 7 and a waterproof layer 6 from inside to outside, and the waterproof layers 6 are PE and PP composite membranes. According to the flexible freight container provided by the invention, a thermal seal splicing process is adopted, and the production automation degree of the flexible freight container is improved greatly; the flexible freight container has excellent sealing waterproof and moisture-proof performance, and a lining bag does not need to be added; and the overall weight ofthe flexible freight container is reduced, and raw materials are saved.

Description

Technical field [0001] The invention relates to the technical field of container bags, in particular to a thermally spliced ​​container bag. Background technique [0002] With the transformation and upgrading of the industry, new requirements such as more concentrated, efficient and convenient product packaging have been put forward. FIBCs have the advantages of good filling properties and easy loading and unloading, so they are more and more favored by the market. So far, FIBC has become one of the main tools for industrial bulk and powder packaging and transportation in the world, and is widely used in many fields such as chemical industry, minerals, agriculture, building materials, food and medicine. [0003] However, unlike high-tech products such as electronics and communications, the current FIBC is still a labor-intensive product, requiring a large number of skilled operators, labor intensive, and high labor costs. With industrial upgrading and changes in the main labor for...
