[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0022] like Figures 1 to 5 As shown, the embodiment of the utility model discloses a packaging material with a self-peelable sealing tape plastic layer, comprising a fixed bottom edge 8, a packaging material body and a sealing tape, wherein the sealing tape comprises an adhesive portion 5 and a plastic sheet 6, wherein the adhesive portion can be bonded to the packaging material body, the fixed bottom edge can be installed at a preset position, the bottom of the packaging material body is connected to the fixed bottom edge through a separating portion, the plastic sheet is connected to the fixed bottom edge, the plastic sheet covers the adhesive portion in a first state, and is separated from the adhesive portion in a second state. In this embodiment, the first state is the original state without food, and the second state is the state after food is loaded.

[0023] The fixed bottom edge comprises a bottom edge body, and a preset position of the bottom edge body is provided with at least one fixed process hole 7. The provided fixed hole is used to fix the packaging material body on the operating table for food packaging, and accordingly, a fixed column or fixed support corresponding to the fixed hole is provided on the operating table.

[0024] At least one heat sealing hole 9 is provided at a preset position of the bottom edge body. In this embodiment, the fixed bottom edge is composed of a plurality of plastic sheets stacked together. By providing heat sealing holes at the preset positions, a certain number of plastic sheets can be stacked and placed, so as to facilitate the completion of a certain number of food packaging at a fixed station.

[0025] The packaging material body includes a front sheet 4 and a back sheet 11. The front sheet and the back sheet have the same main body specifications and are connected at their edges. A sealing tape is provided on the portion of the front sheet protruding from the back sheet. Specifically, the front sheet and the back sheet are both food-grade packaging materials capable of packaging food. The connection between the front sheet and the back sheet is bent based on a bending mechanism or connected as a whole by heat sealing to form an integral packaging material.

[0026] In order to facilitate the removal of certain types of food, such as ready-to-eat food, as a preferred embodiment, the front sheet of the packaging material body is provided with a tearing opening 1 and a pull strip 3, and a circle of head heat seal 2 is provided around the tearing opening, that is, the head heat seal is provided on the front sheet and the back sheet, and one end of the pull strip is provided in the tearing opening. The user can separate the front sheet by pulling down the pull strip through the tearing opening, and then conveniently take out the food in the packaging material body.

[0027] As an optional embodiment, in this embodiment, the pull strip is arranged along the midline of the front sheet. In other optional embodiments, the pull strip can also be arranged on the side or any other suitable position.

[0028] Furthermore, the separation part is specifically a dotted line 10 cutting process performed on the connection between the packaging material body and the fixed bottom edge, and the other end of the dotted line cutting is the fixed bottom edge. The dotted line cutting facilitates the staff who fills the food to conveniently separate the fixed bottom edge from the packaging material body. After the fixed bottom edge and the packaging material body are separated from the dotted line, the plastic layer of the sealing tape is fixed on the fixed bottom edge, so that no independent plastic sheet foreign matter is generated.

[0029] The packaging material disclosed in the utility model is not limited to the structure of the packaging material body, and any possible shape that can realize food packaging is acceptable. The shape and size of the packaging material body and the fixed bottom edge are different for different food materials. The packaging material can be in the form of a bag or a sheet, and the material of the packaging material can be plastic, paper, or paper plastic, etc. Figure 6 As shown, it is an optional packaging material structure, which may specifically include independent graphics, that is, a packaging bag with a complete rectangular structure, or a combination of multiple segments of graphics, such as being divided into two parts from top to bottom, or three parts, upper, middle and lower, or other shapes suitable for food ingredients. Among them, the middle part is a trapezoidal structure, the upper part is a rectangular head, and the lower part is processed into a short inverted trapezoidal structure; or an arc surface adjustment is performed at any of the above graphics, that is, a trapezoidal structure with arc edges on the side, and / or a hemispherical head and / or a regular / irregular bottom edge graphic that is easy to detach from the bottom edge. The above statements and the changes described in the corresponding drawings are only to illustrate that the structure of the packaging bag can be adaptively adjusted, and are not limited to specific shapes and the number of multi-segment graphics.

[0030] The structure and shape of the fixed bottom edge can be adjusted according to actual conditions; the upper end of the fixed bottom edge, that is, the structure connected to the packaging material body, can also be adjusted according to actual conditions, that is, the length of the sealing tape can be the same as or different from the overall length of the fixed bottom edge.

[0031] As mentioned above, at least one fixed process hole is provided at a preset position of the bottom edge body, and at least one heat sealing hole is provided at a preset position of the bottom edge body. Figure 7 As shown, the number and position of the fixing holes can be set to ensure that they match the fixing parts corresponding to the packaging table. As a preferred embodiment, there are at least two fixing holes to ensure stable fixation during packaging. When the number of fixing holes is multiple, each fixing hole can be regularly arranged or irregularly arranged.

[0032] Similarly, the shapes and sizes of the fixed process holes and heat-sealing holes will also vary on different packaging materials, and will be adjusted according to specific practical scenarios. The number of heat-sealing holes is generally multiple. When the number of heat-sealing holes is multiple, each heat-sealing hole can be regularly or irregularly arranged. The location of the heat-sealing holes can be inside the bottom body, or on any side / bottom of the bottom body, and the bottom is more preferred.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
