Abstract
The invention discloses a waist-binding lining bag for flexible ton packaging, which is made of a high-strength heat-sealable woven cloth composite film and comprises a bag body, wherein the bag body is of a hexahedral structure, a feed inlet is formed in the center of the top of the bag body, and a discharge outlet is formed in the center of the bottom of the bag body; the bag body part of the bag body is formed by connecting a plurality of surfaces through heat sealing, an arc-shaped welding line is formed between two adjacent surfaces through heat sealing, the arc-shaped welding line is perpendicular to the horizontal plane, a flash is left outside the arc-shaped welding line, and the flash is connected with an outer bag of a flexible bulk-packed (FIBC) bag. The lining bag can bear larger tensile stress, the vertical edges are connected by the arc-shaped welding lines, and the lining bag can share part of the tensile stress borne by the flexible ton package, so that the problem of bulging after the flexible ton package is filled with materials is effectively relieved.
Description
Technical Field
The invention relates to the technical field of packaging, in particular to a girdling lining bag for flexible ton packaging (FIBC).
Background
The flexible ton packaging bag (FIBC), also called flexible container bag, has the characteristics of large volume, light weight, suitability for mechanized operation, convenient loading and unloading, etc., and is an ideal choice for packaging, transporting and storing granular goods. Flexible container bag is generally made by rubber coating cloth, resin processing cloth or soft material, leads to the bag body to have certain elasticity, and the bag body is after filling with the material, under the effect of material gravity, can have the condition of "tripe" to appear expanding, and the whole bag body is toward cylindrical orientation inflation. The standard container is adopted for sea transportation or land transportation, the sizes of the flexible freight bags are customized according to the size of the container, for example, three flexible freight bags can be loaded in a row of the container, but only two flexible freight bags can be loaded due to the expansion of the container, so that the transportation efficiency is greatly reduced, and the transportation cost is increased. The traditional processing mode is processed on the outer bag of the packaging bag, reinforcing ribs are arranged on the outer bag, reinforcing hoops are arranged on the reinforcing hoops, reinforcing pieces, lacing wires and the like to offset the phenomenon of 'bulging', the processing method not only increases the cost of the outer bag, but also influences the attractiveness and the use of the outer bag, a new method is needed, a method is found, the phenomenon of 'bulging' is offset under the condition that the outer bag is not changed, and the flexible packaging bag is still perfect in plasticity after being filled with materials. Based on this, the present invention proposes a corset lining bag for flexible ton packaging (FIBC) to solve the above problems.
Disclosure of Invention
The present invention is directed to solving the problems of the prior art by providing a corset lining bag for flexible ton packaging (FIBC).
The invention is realized by the following technical scheme:
a waist-binding lining bag for flexible ton packaging comprises a bag body, wherein a feeding hole is formed in the top of the bag body, and a discharging hole is formed in the bottom of the bag body; the bag body part of the bag body is formed by connecting a plurality of surfaces through heat sealing, an arc-shaped welding line is formed between two adjacent surfaces through heat sealing, the arc-shaped welding line is perpendicular to the horizontal plane, and a flash is left outside the arc-shaped welding line.
Furthermore, the bag body is of a hexahedral structure, and is connected through heat sealing to form four arc-shaped welding lines which are vertical to the horizontal plane.
Further, the arc height of the arc-shaped welding line is 80mm, and the chord length is 1150 mm.
Furthermore, the lining bag is made of a high-strength heat-sealing woven cloth composite film.
Further, the flash is connected to a flexible ton packing (FIBC) outer bag.
Further, the feed inlet sets up in bag body top central authorities, and the discharge gate sets up in bag body bottom central authorities.
Furthermore, the feed inlet and the discharge outlet are both square tubular.
The invention has the beneficial effects that:
the waist-binding lining bag for flexible ton packaging adopts the heat-sealable woven cloth composite film material, and can bear larger tensile stress. After the bag body is filled with the material, the middle part of the bag body receives that tensile moment is the biggest, therefore the expansion deformation is also the biggest, the arc welding seam connection is adopted to the vertical edge, and the bag body middle part is gone to, two welding seam intervals of every face are short more, can effectively offset the bag body and at the expansion extension after filling with the material, play the effect of giving bag body middle part "beam waist", greatly reduced the tensile stress that the outer bag of flexible ton packing received, make ordinary flexible container bag after filling with the material, still keep original tetragonal body appearance.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1-2, an embodiment of the invention provides a waist-restraining lining bag for flexible ton packaging, the lining bag is made of a high-strength heat-sealable woven fabric composite film, the lining bag comprises a bag body 1, a feeding hole 2 is formed in the top of the bag body 1, and a discharging hole 3 is formed in the bottom of the bag body; the bag body part of the bag body 1 is formed by connecting a plurality of surfaces through heat sealing, an arc-shaped welding line 4 is formed between two adjacent surfaces through heat sealing, the arc-shaped welding line 4 is vertical to the horizontal plane, a flange 5 is reserved outside the arc-shaped welding line 4, and the flange 5 is connected with an outer bag of a flexible bulk-packed (FIBC) bag.
In the embodiment of the invention, the bag body 1 is of a hexahedral structure, the bag body has four faces, the four faces are connected through heat sealing to form four arc-shaped welding lines 4, and the arc-shaped welding lines 4 are vertical to the horizontal plane; the arc height of the arc-shaped welding line 4 is 80mm, and the chord length is 1150 mm. The feed port 2 is arranged in the center of the top of the bag body 1, and the discharge port 3 is arranged in the center of the bottom of the bag body 1; the feed inlet 2 and the discharge outlet 3 are both square tubular.
