Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] One embodiment of this application provides a heat-shrinkable film zipper door, such as... Figure 1 As shown, it includes: a heat shrink film zipper door body 1, which is rectangular and made of heat shrink film material; it can be used in various environments and has UV resistance; the heat shrink film zipper door body 1 is heat-pressed around its perimeter to form a first sealing edge 2;

[0022] The heat shrink film zipper door body 1 is connected to the four sides of the first connector 3. The heat shrink film zipper door body 1 is detachably connected to the preset position of the large packaging structure through the first connector 3. The first connector 3 is an adhesive strip or a snap fastener. The structure of the adhesive strip or snap fastener is the prior art and will not be described in detail here.

[0023] The heat shrink film zipper door body 1 has a groove, and a door panel 4 is formed in the groove on the heat shrink film zipper door body 1. The bottom of the door panel 4 is integrally connected to the heat shrink film zipper door body 1. The rest of the periphery of the door panel 4 is connected to the heat shrink film zipper door body 1 by a zipper 5. That is, the door panel 4 is a door or window of the heat shrink film zipper door body 1. The zipper 5 is a double zipper pull zipper, which is existing technology and will not be described in detail. The double zipper pull zipper facilitates the opening of the zipper 5 by operators inside and outside the large packaging structure.

[0024] In one embodiment, the heat-shrinkable film zipper door body 1 extends to form an extended body 6 at the end away from the zipper 5, and the extended body 6 is heat-pressed around its perimeter to form a second sealing edge 7. The extended body 6 is used to observe the internal and external conditions of large packaging structures.

[0025] The extended body 6 is connected to the four sides by a second connector 8. The extended body 6 can be detachably connected to a preset position of a large packaging structure through the second connector 8. The second connector 3 is an adhesive strip or a snap fastener. The structure of the adhesive strip or snap fastener is existing technology and will not be described in detail here.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0030] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
