Embodiment Construction
[0031] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.
[0032] Such as Figure 1-9 As shown, a square inner bag of a container bag of the present invention includes an inner bag body 130, a feeding part 110, a necking part 120 and a discharging part 140. The inner bag body 130 includes a front, a back, a left side and a right side, The front and the left, the front and the right, the right and the back, and the back and the left are all provided with inner tie bars 2, and the inner tie bars 2 are provided with a plurality of feeding holes 220. The inner tie rib 2 is set to connect the adjacent surfaces of the inner bag body 130 to play the role of fixed support and stretching. The inner tie rib 2 is provided with a feeding hole 220, which can fully Take advantage of inner pocket space.
[0033] The feeding part 110...

The invention discloses a flexible container square inner bag and a preparation method thereof. The flexible container square inner bag comprises an inner bag body, a feeding part, a necking part anda discharge part; the inner bag body comprises a front surface, a rear surface, a left surface and a right surface; inner tension ribs are arranged between the front surface and the left surface, between the front surface and the right surface, between the right surface and the rear surface, and between the rear surface and the left surface; and the inner tension ribs are provided with a pluralityof feed ports. The flexible container square inner bag is provided with the inner tension ribs which play a role in supporting the inner bag body, mounting positions of the inner tension ribs are reasonably arranged, and the flexible container square inner bag is of a square structure when in use, so that the space is saved, and the transportation is stable. The preparation method comprises the following steps of (1) preparing a high-performance polyethylene film by using three-layer coextrusion film blowing, assisted by a collapsible folding mechanism at the same time, (2) preparing a semi-finished product by controlling heat-sealing parameters to control the heat-sealing strength, (3) manufacturing the inner tension ribs, (4) manufacturing a bag, and (5) sealing edges. The preparation process is reasonable and the operation is simple.
Description
technical field [0001] The invention belongs to the technical field of container bags, in particular to a square inner bag of container bags and a preparation method thereof Background technique [0002] With the globalization of commercial trade and the development of transportation, container bags are widely used in transportation. Due to the long transportation time of using container bags to transport goods, the transportation of goods is seriously affected by the surrounding environment. Therefore, when using container bags for transportation, it is necessary to set inner bags in the container bags, and cooperate with the container bags to serve as a storage space for the goods. effect. In the prior art, since the inner bag of the centralized bag is made of plastic inner bag blown according to the size of the container bag, the plastic inner bag is cylindrical or irregular in shape after holding objects, so it takes up a lot of space during use and increases At the sa...
