Description

Technical Field

[0001] This utility model relates to the field of packaging products, and in particular to a non-woven bag. Background Technology

[0002] Non-woven bags are a commonly used packaging material. The structure of the non-woven bags currently in use is shown in patent publication document CN205837485U. There is a problem with this type of non-woven bag during use, namely, the bag opening cannot be sealed when in use. Therefore, when carrying items, it is easy for garbage and foreign objects in the environment to mix into the non-woven bag. Utility Model Content

[0003] This utility model addresses the above-mentioned problems by proposing a non-woven bag.

[0004] The technical solution adopted by this utility model is as follows: A nonwoven bag includes a composite film, which is laminated together to form a bag body. The bag body has a handle at the opening and two magnetic closures. The magnetic closures are respectively disposed on the inner walls of both sides of the bag body and are located at the opening of the bag body. The two magnetic closures are parallel to each other. The bottom of the bag body has a rigid PE material support strip, which is a flat-bottomed U-shaped support strip.

[0005] This type of non-woven bag is formed by sewing together a composite film. The bag opening has magnetic tabs that attract each other. When the bag opening needs to be closed, the two magnetic tabs attract each other. When the bag opening needs to be opened, simply pull the two handles from both sides. Pulling the handles opens the bag opening. When the pulling force is removed, the bag opening will magnetically re-enter due to the magnetic attraction of the two magnetic tabs. Therefore, this type of non-woven bag can automatically close and seal the bag opening. To open the bag, simply pull the handles.

[0006] In this type of non-woven bag, a support strip is provided at the bottom of the bag body. This flat-bottomed, U-shaped support strip has three sides: one flat-bottomed side is attached to the bottom edge of the bag body, while the other two side edges are attached to the sides of the bag body. This support strip allows the bottom of the non-woven bag to be kept open, ensuring that the bag can be used to store items that are easily compressed or deformed. Simultaneously, the support strip at the bottom of the bag acts as a reinforcing rib, further improving the load-bearing capacity of the bottom of the bag and preventing it from cracking under excessive weight.

[0007] In summary, this type of non-woven bag features magnetic suction pieces at the bag opening that attract each other, enabling the bag to automatically close. When needed, the bag can be opened by pulling the handle. Meanwhile, the support strip at the bottom of the bag ensures that the bottom of the bag is always open, thus allowing the non-woven bag to be used to store easily deformable items.

[0008] Optionally, the stretching strip is located on the outer wall of the bag, and there are at least two stretching strips, which are not in contact with each other.

[0009] The bag features multiple stretch strips that do not touch each other, which improves the stretching effect on the bottom of the bag and enhances its strength.

[0010] Optionally, the bag body has a display opening, and a transparent plate is provided on the display opening.

[0011] The transparent panel is made of PE material and is attached to the bag body by heat bonding. The purpose of the display opening is to facilitate observation of the contents inside the bag.

[0012] Optionally, the composite film includes a non-woven fabric layer, a printed film layer, a laser film layer, and a PE coating layer. The PE coating layer is disposed between the non-woven fabric layer and the printed film layer. An adhesive layer is disposed between the printed film layer and the laser film layer. A varnish layer is disposed on one side of the laser film layer.

[0013] The composite membrane is made of non-woven fabric layer, printed film layer, laser film layer and PE coating layer to ensure that the entire composite membrane has good sealing and barrier properties. If the bag contains liquid, the bag can contain the liquid and prevent it from spilling into the environment.

[0014] Optionally, the laser film layer is an OPP laser film layer, and the printed film layer is an OPP printed film layer.

[0015] Optionally, the thickness of the laser film layer is 17 micrometers, and the thickness of the printed film layer is 15 micrometers.

[0016] Optionally, the thickness of the adhesive layer is 2 micrometers, and the thickness of the PE coating layer is 15 micrometers.

[0017] Optionally, the basis weight of the nonwoven fabric layer is 100 g / m². 2 The thickness of the varnish layer is 1 micrometer to 3 micrometers.

[0018] The beneficial effects of this utility model are: by setting magnetic suction pieces with mutual attraction at the bag opening, the bag can automatically close and seal. When needed, the bag can be opened by pulling the handle. At the same time, the expansion strip at the bottom of the bag can ensure that the bottom of the bag is always in an open state, thus ensuring that the non-woven bag can be used to store some easily deformable items.
