[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment: a high barrier round bottom bag, including a bag body 1, the bag body 1 is made of polyethylene material, the integrity and appearance of the bag can be maintained through the design of the bag body 1, the bag body 1 is internally slidably connected with a drawstring 2, the bag opening is tightened by the drawstring 2, the outer front side of the bag body 1 is rotatably connected with an anti-drop strip 3, the outer front side of the bag body 1 is fixedly connected with a placement bag 4, a note is placed through the placement bag 4, the outer front side of the placement bag 4 is fixedly connected with a connection component, the connection component includes an adhesive strip 5, the inner side of the anti-drop strip 3 The side wall is fixedly connected with a fixing strip 6, and the sticky note placed inside the bag 4 is fixed by means of the adhesive strip 5 and the fixing strip 6. The outer wall of the adhesive strip 5 is in contact with the outer wall of the fixing strip 6. The bottom of the bag body 1 is fixedly connected with a waterproof support layer 8. The material of the waterproof support layer 8 is polyurethane. The design of the waterproof support layer 8 can effectively prevent water from seeping in from the contact with the ground and polluting the inside of the bag body 1. The top of the waterproof support layer 8 is fixedly connected with a wear-resistant layer 7. The material of the wear-resistant layer 7 is nylon membrane material. The design of the wear-resistant layer 7 can well block gas.
[0027] Reference Figure 3-Figure 4The outside of the wear-resistant layer 7 is fixedly connected with a heat-insulating layer 9, which is made of PET material. The stability of the bag is improved by the heat-insulating layer 9. The end of the heat-insulating layer 9 away from the wear-resistant layer 7 is fixedly connected with a sealing layer 10, which is made of EVOH material. The design of the sealing layer 10 isolates oxygen. The end of the sealing layer 10 away from the heat-insulating layer 9 is fixedly connected with a barrier layer 11, which is made of aluminum foil film. The design of the barrier layer 11 protects the items in the bag from light and heat.
[0028] Working principle: When the staff uses the bag body 1, the bag body 1 is placed on the ground. Due to the material design of the bag body 1 and the waterproof support layer 8, the bag body 1 remains upright and prevents external water from entering the bag body 1. After the bag body 1 is placed, the drawstring 2 is tightened to shrink the bag mouth, and then the label is placed in the placement bag 4. The anti-drop strip 3 is rotated to make the adhesive strip 5 and the fixing strip 6 adhere to prevent the label from falling. Since the wear-resistant layer 7 is made of nylon film, it can block the gas very well. Since the heat insulation layer 9 is made of PET, the stability of the bag is improved. Since the sealing layer 10 is made of EVOH, oxygen is isolated. The barrier layer 11 is made of aluminum foil film. The design of the barrier layer 11 protects the items in the bag from light and heat, thereby performing multi-directional isolation of the items inside the bag body 1 to prevent external factors from affecting the items inside the bag body 1, and at the same time maintaining the freshness of the items inside the bag body 1.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
