Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to packing bag technical field especially, it is an edge sealing packing bag with card inserting structure. BACKGROUND
[0002] As a commonly used packing bag, the edge sealing packing bag has good sealing and barrier properties, can be used for packing and storing various substances with different properties (such as acid and alkali) and different states (such as solid, liquid and milk), and has low cost and is convenient for transportation. In some practical use occasions, such as display on a shelf or storage on a storage rack, a price tag or a label needs to be placed, and since the edge sealing packing bag has weak supporting property, labels are mostly pasted on the outside of the packing bag, which affects the appearance of the edge sealing packing bag and has low flexibility, especially when the price tag is placed on the shelf and the price is adjusted, the label is not easy to replace. SUMMARY
[0003] The utility model discloses a kind of edge sealing packing bags with card inserting structure, which is convenient for setting label.
[0004] To achieve the above object, the utility model adopts the following technical scheme: an edge sealing packing bag with card inserting structure, comprising an edge sealing packing bag body, a hollow slot is provided on the edge sealing packing bag body, the edge sealing packing bag body is composed of at least a PET film and a PE film, the PET film of the edge sealing packing bag body is separated from the PE film by a release layer at the hollow slot, and the PET film of the edge sealing packing bag body is provided with a slot opening at the upper end of the hollow slot.
[0005] Specifically, the side of the PE film close to the PET film is further provided with an aluminum foil layer or an aluminum plating layer.
[0006] Specifically, a pasting fixing part is provided at both ends of the slot opening, and the pasting fixing part is pasted and fixed to the outside of the PET film.
[0007] Specifically, a printing film layer is further provided on the outside of the PET film of the edge sealing packing bag body, and the printing film layer covers the outside of the pasting fixing part.
[0008] The utility model has the advantages that: by providing a slot opening on the outer PET film of the edge sealing packing bag body, and separating the outer PET film and the inner PE film by a release layer, a hollow slot is formed on the edge sealing packing bag body, which can be used for placing various labels, and the practicality of the edge sealing packing bag is improved. BRIEF DESCRIPTION OF DRAWINGS
[0009] ATTACHMENT Fig. 1 It is an external structure schematic view of the edge sealing packing bag with card inserting structure in the embodiment.
[0010] Appendix Fig. 2 This is a cross-sectional view of the sealed packaging bag with a card insertion structure in the embodiment. Detailed Implementation
[0011] Example 1, referring to Figs. 1-2 A sealed packaging bag with a card insertion structure includes a sealed packaging bag body 1, a hollow slot 2 provided on the sealed packaging bag body 1, the sealed packaging bag body 1 is composed of at least a PET film 11 and a PE film 12, the PET film 11 of the sealed packaging bag body 1 is separated from the PE film 12 at the hollow slot 2 by a release layer 13, and the PET film 11 of the sealed packaging bag body 1 has a slot opening 14 at the upper end of the hollow slot 2.
[0012] In this embodiment, the hollow slot 2 is formed between the outer PET film 11 and the inner PE film 12 of the sealed packaging bag body 1, and the PET film 11 and PE film 12 are separated by the release layer 14. For the most basic sealed packaging bag body 1, it is made by laminating the outer PET film 11 and the inner PE film 12. When making the sealed packaging bag body 1, the PET film 11 and PE film 12 are first laminated to obtain the packaging film, and then the multiple pieces of the cut packaging film are heat-sealed to obtain the sealed packaging bag. In this embodiment, before the PET film 11 and PE film 12 are laminated, a release agent is sprayed locally on the side where the PET film 11 and PE film 12 are laminated to form a release layer 14. The area where the release agent is sprayed separates the PET film 11 and PE film 12 when they are laminated, thus forming a hollow slot 2. Finally, after the processing of the sealed packaging bag body 1 is completed, an opening is cut in the hollow slot 2 on the PET film 11 to form the slot 14 opening.
[0013] In a further preferred embodiment, an aluminum foil layer 15a or an aluminized layer 15b is provided on the side of the PE film 12 near the PET film 11. When there are high requirements for the sealing and barrier performance of the sealed packaging bag, an aluminum foil layer 15a or an aluminized layer 15b is provided between the PET film 11 and the PE film 12. The aluminum foil layer 15a or the aluminized layer 15b is bonded to the PE film 12. When using the aluminum foil layer 15a, it is bonded and fixed to the PE film 12 with a specific adhesive. When using the aluminized layer 15b, the PE film 12 is subjected to an aluminum vapor deposition device to form an aluminized layer 15b on its surface. The PE film 12 with the aluminum foil layer 15a or the aluminized layer 15b is then laminated with the PET film 11 through the above processing method, and then heat-sealed to obtain the sealed packaging bag body 1 with better sealing and barrier performance.
[0014] In a further embodiment, adhesive fixing parts 3 are provided at both ends of the slot opening 14, and the adhesive fixing parts 3 are adhered and fixed to the outside of the PET film 11. The adhesive fixing parts 3 can improve the stability of both ends of the slot opening 14 and prevent the slot opening 14 from being easily torn open. In addition, in order to improve the overall aesthetics of the sealed packaging bag, a printed film layer (not shown in the figure) can be additionally provided on the outside of the PET film 11 of the sealed packaging bag body. The printed film layer also covers the outside of the adhesive fixing parts 3. The adhesive fixing parts 3 and the printed film layer can be processed before the packaging film is heat-sealed into the sealed packaging bag body. Specifically, after the PET film 11 is laminated with the PE film 12, the adhesive fixing parts 3 can be directly provided at both ends where the slot opening 14 is to be opened, and then the printed film layer is laminated on the outside of the PET film 11. After printing is completed, the slot opening 14 is opened. Both the adhesive fixing parts 3 and the printed film layer can be made of PET film material. Of course, for ease of processing, after attaching the fixing part 3, printing can be done directly on the outside of the PET film 11 without setting a separate printing film layer. Of course, this will sacrifice some of the aesthetics, and can be adjusted accordingly according to actual needs.
[0015] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
