[0002] Packaging bags refer to bags used to pack various items, so that the goods can be easily transported and stored during the production and circulation process. They are widely used in daily life and industrial production, including in the current takeaway industry. Many businesses store takeaways. After the food and goods are packed, they are generally placed in packaging bags, affixed with adhesive strips, and then delivered by takeaway deliverymen. In order to reassure customers, ordinary packaging bags are generally sealed by stores and adhesive strips are attached to the seals to form a one-time anti-damage and recovery seal. However, the sealing design of the non-packaging bag itself is easy to be re-sealed after opening, and it is difficult to ensure that there is no opening problem from the meal to the customer opening. The purpose of the packaging bag with a one-time anti-damage effect is that it will not be opened at will by other people other than customers during the delivery process after the takeaway is packed, so that the entire takeaway sales and delivery process can gain the trust of customers, ensure that the goods received by customers are directly packed by the store, protect the privacy of customers, and reduce disputes between stores, customers and deliverymen.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] like Figure 1-6 The utility model shown in the figure discloses a packaging bag structure, such as Figure 1 The bag body 1 of the packaging bag of the present embodiment shown includes a bottom film 2 for forming a pocket-shaped containing cavity 5 with an opening 4 and a plurality of side films 3, wherein the bottom film 2 and the side films 3 can be sealed and bonded with adhesive to form a pocket shape with reference to the paper bag in the prior art, and a hand rope 6 is provided at the side film 3 near the opening 4 of the containing cavity 5, and the hand rope 6 is used to pull the packaging bag when in use, and an interlayer portion 21, a moisture absorption layer 22, and an impermeable bag 23 are provided in the containing cavity 5 formed by the side film 3 and the bottom film 2. The impermeable bag 23 is provided on the bottom film 2 and attached to the side film 3, and the interlayer portion 21 is located in the impermeable bag 23, and a moisture absorption layer 22 for absorbing moisture and soup is provided below the interlayer portion 21 with leakage holes, which is used to absorb a small amount of water vapor emitted from the food and goods contained in the bag body 1 when in use, especially to absorb condensed water that is easy to occur on food and milk tea with ice cubes in summer, such as Figure 2-3 The anti-seepage bag 23 is placed in the bottom of the storage cavity 5 in a pocket shape, and the moisture-absorbing layer 22 is located between the interlayer parts 21. In addition, the hand rope 6 of this embodiment is exposed outside the side sheet 3 in the middle, and the two ends extend into the inside of the side sheet 3 through the perforations 31 provided on the side sheet 3. The side sheet 3 is provided with a viscose sealing part 7 opposite to the hand rope 6. Figure 2-3 As shown, the hand rope 6 also has the function of forming a release paper for the adhesive layer 71. When not in use, the hand rope 6 extends into the bag body 1 and adheres to the outside of the adhesive layer 71. When in use, the hand rope 6 located on the outside of the side panel 3 is pulled by external force, so that the overlapping hand rope 6 can be released from the adhesive layer 71 from the far end of the perforation 31. Figure 4 As shown, after the hand rope 6 is pulled, the hand rope 6 is pulled out from the middle, and the hand rope 6 located inside is pulled out from the middle. Figure 4 The two sides begin to shrink toward the middle, and during this process, the hand rope 6 and the adhesive layer 71 are released from adhesion. Finally, after the hand ropes 6 on the two side sheets 3 are all pulled out, the hand ropes 6 and the adhesive layer 71 are also completely released from adhesion, and the adhesive layers 71 set on the side sheets 3 on both sides can also be bonded accordingly, completing the process as shown in FIG. Figure 5 The packaging state is shown, and a Velcro parent-child surface 37 is also provided on the handle rope 6, and the Velcro parent-child surface 37 on the handle rope 6 installed on the side piece 3 on both sides of each packaging bag is respectively set to a furry surface and a thorny surface, thereby ensuring that the two handle ropes 6 of each packaging bag can be bonded to each other through the furry surface and the thorny surface of the Velcro.

[0019] As a further configuration of the above scheme, the adhesive sealing portion 7 includes an adhesive layer 71 fixed on the side piece 3, and the adhesive layer 71 is correspondingly arranged on the inner side of the two side pieces 3 in the containing cavity 5, referring to Figure 2-4 The adhesive sealing part 7 shown is used to expose the adhesive layer 71 and make the adhesive layers 71 arranged on the side panels 3 on both sides adhere to each other by pulling the hand rope 6 after packaging, so as to complete a one-time sealing. The adhesive strength on the two side panels of the adhesive layer 71 is greater than the connection strength between the adhesive layer 71 and the side panels 3. Its function is that after the adhesive layer 71 on the two side panels 3 completes a adhesive sealing, if someone forcibly separates it midway, the adhesive layer 71 on one side will be separated from the side panel 3, so that the customer can clearly find that the packaged bag has been opened, thereby ensuring the privacy and safety of the package bag.

[0020] As a further arrangement of the above scheme, the hand rope 6 extends into the side panel 3 through the perforation 31, and both ends thereof are provided with limit buckles 61 which are larger than the perforations 31. The function of the limit buckles 61 is to prevent the ends of the hand rope 6 from being separated from the side panel 3, and the hand rope 6 is flat and has a release surface on the side facing the adhesive layer 71. The function of the release surface is to protect the adhesive layer 71, and when the packaging bag is used, the protection is released by pulling the hand rope 6 to expose the adhesive layer 71. Compared with the prior art, there is no need to tear off ordinary release paper, which, on the one hand, reduces waste and reduces the generation of release paper garbage, and on the other hand, improves the convenience of use. The parts of the hand rope 6 exposed from the side panel 3 are also respectively provided with Velcro parent and child surfaces 37.

[0021] As a further configuration of the above scheme, the bottom film 2 and the side film 3 are both made of a multi-layer composite, and the inner layer is provided with an aluminum foil insulation layer, which is compounded in the bag body 1 to improve the insulation effect of the packaging bag, and can also improve its anti-seepage, anti-leakage effect and strength, and can also be set or not according to actual needs.

[0022] As a further configuration of the above scheme, the side panel 3 is further provided with a U-shaped card sleeve 33 and a layered spacer 34. The U-shaped card sleeve 33 is arranged on the inner wall of the side panel 3, and the layered spacer 34 has an insert portion 35 and a partition plate 36 that match the U-shaped card sleeve 33. This embodiment takes into account the prior art, especially the packaging bags for takeout, which sometimes require a multi-layer design to meet the needs of isolating and placing meals that need to be separated and packaged. For example, hamburgers and French fries in fast food are easy to squeeze each other and affect the appearance of the meals. After individual packaging, they can be separated into upper and lower layers. For example, between multiple cups of milk tea with different temperatures, ice milk tea can be placed on the lower layer, and room temperature or hot milk tea can be placed on the upper layer, and the upper and lower layers can be separated and stacked.

[0023] As described above, the packaging bag of this embodiment is more convenient to use than the prior art. First, after placing food or goods in the bag of this embodiment, you only need to pull the hand rope on the outside of the side piece and pull it away from the adhesive layer to bond the side pieces on both sides at one time. Second, the design of the adhesive layer can also isolate the inside and outside, prevent the goods in the bag from falling out of the paper bag and causing loss, and prevent the items in the bag from being opened and sealed again. When the adhesive layer of this embodiment is disassembled, the two side pieces are directly torn apart along the bonding point. When tearing, based on the adhesive layer, the two side pieces can be torn apart. The setting of the adhesive capacity of the adhesive layer will inevitably cause the adhesive layer to separate from the side piece on one side, so that the adhesive will not stick to the food or hands when taking it away, and the design makes it possible for the adhesive layer to show obvious signs of being torn if the paper bag has been opened, thereby protecting privacy. The bag body of the third embodiment is also provided with a moisture-absorbing interlayer portion at the bottom of the bag body, which is convenient for absorbing a small amount of condensed water and soup dripping from the surface of the food when used for food delivery packaging, and an interlayer sheet is provided to facilitate the mutual squeezing of the upper and lower layers of the packaging boxes when the food is stacked in multiple layers.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
