Description

Technical Field

[0001] This utility model relates to the field of packaging bags, and in particular to a non-woven stand-up pouch. Background Technology

[0002] Non-woven bags are a commonly used type of tote bag. To ensure that non-woven bags can stand upright, patent publication CN221234350U discloses a non-woven bag that can stand upright. In this type of non-woven bag, an extendable connecting component is set at the bottom of the bag body made of non-woven fabric. The entire non-woven bag can stand upright by expanding the connecting component. However, there is a problem with this type of self-standing non-woven bag during use. If a heavy object is placed inside the non-woven bag and the connecting component is crushed, the entire non-woven bag will not be able to stand upright. Therefore, the reliability of using the connecting component to expand the non-woven bag to achieve self-standing is relatively poor. Utility Model Content

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

[0004] The technical solution adopted by this utility model is as follows:

[0005] A nonwoven stand-up pouch includes a bottom sheet and side sheets, which are joined together to form a cylindrical bag body. The bottom sheet is disposed on one side of the bag body. Each side sheet includes a side heat-sealing film layer, a nonwoven fabric layer, and a side printed film layer. The side heat-sealing film layer and the side printed film layer are respectively disposed on both sides of the nonwoven fabric layer. A first resin coating layer is disposed between the side heat-sealing film layer and the nonwoven fabric layer, and a second resin coating layer is disposed between the side printed film layer and the nonwoven fabric layer.

[0006] In this type of nonwoven stand-up pouch, the main body of the bag side panel is a nonwoven fabric layer. The two sides of the nonwoven fabric layer are laminated with a resin coating layer and other film layers. The resin coating layer and other film layers improve the stiffness of the nonwoven fabric layer, thus ensuring that the entire bag has relatively better stiffness. This allows the entire stand-up pouch to stand upright. Furthermore, since the items are not squeezed when placed in the bag, it ensures that the self-standing effect of the entire stand-up pouch is not affected after the items are placed inside.

[0007] In summary, this type of nonwoven stand-up pouch improves the stiffness of the nonwoven layer by attaching a resin coating layer and other films to the nonwoven layer, ensuring that the entire nonwoven bag can stand upright and that the bag will not be squeezed after items are placed inside, thus not affecting the stand-up effect of the entire bag.

[0008] Specifically, in this type of nonwoven stand-up pouch, one side of the bag body is the bag bottom piece, and the other side of the bag body is provided with a carrying strap.

[0009] Optionally, it may also include an adhesive layer disposed between the second resin coating layer and the side-printed film layer, wherein an ink printing layer is disposed between the side-printed film layer and the adhesive layer.

[0010] Optionally, the side-printed film layer includes a PET film or a BOPP film.

[0011] The printing film layer uses PET film or BOPP (biaxially oriented polypropylene) film to ensure the barrier properties and stiffness of the bag.

[0012] Optionally, the nonwoven fabric layer has a basis weight of 40 g / m², and the side-printed film layer has a thickness of 12 micrometers to 15 micrometers.

[0013] Optionally, the thickness of the first resin coating layer is 20 micrometers, and the thickness of the second resin coating layer is 20 micrometers.

[0014] Optionally, the bag bottom sheet includes a functional film layer, a bottom printed film layer, and a bottom heat-sealing film layer. The bottom heat-sealing film layer and the bottom printed film layer are respectively disposed on both sides of the functional film layer. A first adhesive layer is disposed between the bottom heat-sealing film layer and the functional film layer, and a second adhesive layer is disposed between the bottom printed film layer and the functional film layer.

[0015] Specifically, the bottom heat-sealing film layer is used for bonding with the side heat-sealing film layer on the bag side panel.

[0016] Optionally, the functional film layer includes an aluminized biaxially oriented polypropylene film or a polyester aluminized film.

[0017] The main function of the functional film layer is to ensure that the entire bag bottom can be stretched out. Therefore, the functional film layer in this type of stand-up pouch is made of aluminized biaxially oriented polypropylene film or aluminized polyester film. This ensures that the bag bottom can be stretched out to cover the entire bag, thereby enabling the stand-up pouch to stand stably.

[0018] Optionally, the bottom heat-sealing film layer includes a PE film, and the side heat-sealing film layer includes a PE film.

[0019] The beneficial effects of this utility model are: by attaching a resin coating layer and other films to the non-woven fabric layer, the stiffness of the non-woven fabric layer is improved, ensuring that the entire non-woven bag can stand upright, and the bag will not be squeezed after items are placed inside, thus not affecting the self-standing effect of the entire self-standing bag.

A first adhesive layer is disposed between the bottom heat-sealing film layer 201 and the functional film layer 203, and a second adhesive layer 204 is disposed between the bottom printed film layer 205 and the functional film layer 203.

[0039] Specifically, the bottom heat-sealing film layer 201 is used to bond and cooperate with the side heat-sealing film layer 101 on the side panel 1 of the bag.

[0040] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the functional film layer 203 includes an aluminized biaxially oriented polypropylene film or a polyester aluminized film.

[0041] The main function of the functional film layer 203 is to ensure that the entire bag bottom sheet 2 can be expanded. Therefore, the functional film layer 203 in this type of stand-up pouch is made of aluminized biaxially oriented polypropylene film or aluminized polyester film. This ensures that the bag bottom sheet 2 can expand the entire bag body, thereby enabling the entire stand-up pouch to stand stably.

[0042] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the bottom heat-sealing film layer 201 includes a PE film, and the side heat-sealing film layer 101 includes a PE film.
