Description

TECHNICAL FIELD

[0001] The utility model relates to the field of instant food packaging material, especially to a bowl cover with water drainage function. BACKGROUND

[0002] Dry noodles, as a kind of instant noodles, are very popular among consumers. Consumers add hot water into a container, and after a certain period of time, they drain the hot water through the water drainage hole of the bowl cover, leaving the noodles in the container. A bowl cover with water drainage function is disclosed in patent publication document CN216602374U. This bowl cover with water drainage function is formed by cutting a whole composite film. After cutting, the composite film forms a mother cover (reference number 1 in the document) and a child cover (reference number 2 in the document). In order to ensure that the adhesive layer (reference number 14 in the document, made of LDPE) and the second adapter layer (reference number 15 in the document, mainly made of nylon) can be separated smoothly, a release agent is applied between the adhesive layer and the second adapter layer. The release agent ensures that the adhesive layer and the second adapter layer on both sides of the cut can be separated smoothly. However, due to the release agent, the child cover and the mother cover may be bent or even fall off at the cut, which may cause quality control problems and food safety risks. SUMMARY

[0003] To solve the above problems, the utility model provides a bowl cover with water drainage function. The paper layer and the PE resin layer are combined. The paper layer has good adsorption effect on the release agent (i.e. the release agent layer), which can ensure that the release agent layer can be stably attached to the paper layer. When the paper layer is combined with the PE resin, the part of the paper layer in the area where the release agent is applied has relatively weak composite strength when combined with the PE resin. At the same time, a dot array adhesion area is provided in this area, which adheres to the PE resin without affecting the function of the release agent, providing a certain composite strength. After cutting, the mother cover and the child cover are easily formed without the above problems.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] A bowl cover with water drainage function, comprising a first PET film layer, a second PET film layer, a paper layer, a PE resin layer, an aluminum foil layer, a third PET film layer, and an EVA coating layer. The paper layer and the first PET film layer are respectively arranged on both sides of the second PET film layer. The EVA and modified olefin layer and the aluminum foil layer are respectively arranged on both sides of the third PET film layer. The PE resin layer is arranged between the paper layer and the aluminum foil layer. A release agent layer is arranged between the paper layer and the PE resin layer. A dot array adhesion area is provided in the release agent layer area.

[0006] In the drainage bowl cover, the paper layer and the PE resin layer are combined, the paper layer has good adsorption effect on the release agent (i.e. the release agent layer is the release agent oil), so that the release agent layer can be stably attached to the paper layer, so that the part of the paper layer in the release agent oil coating area has relatively weak composite strength when being combined with the PE resin, and the mother cover and the sub-cover are easily formed after punching.

[0007] Meanwhile, in the drainage bowl cover, the PET film is used to replace the nylon film, so that the entire bowl cover has better stiffness.

[0008] Further comprising an ink printing layer, the ink printing layer is arranged between the first PET film layer and the second PET film layer.

[0009] The ink printing layer is arranged between the first PET film layer and the second PET film layer, and the first PET film layer and the second PET film layer are used to protect the ink printing layer, so as to ensure that the ink printing layer can remain stable for a long time. The specific ink printing layer is formed after the ink is printed on the first PET film layer or the second PET film layer.

[0010] Optionally, the thickness of the ink printing layer is 3um.

[0011] Optionally, the thickness of the first PET film layer is 8um-12um, the thickness of the second PET film layer is 12um, and the thickness of the third PET film layer is 12um.

In addition, a point array of adhesion areas is arranged in the area. As shown in the drawings (Figs. 1 and 2), the white round holes in the drawings are the point array. The point array is adhesively connected to the PE resin without affecting the function of the release oil. The point array provides a certain combined strength. After punching, the mother cover and the child cover are easily formed. Figure 2 As shown in the drawings (Figs. 1 and 2), the white round holes in the drawings are the point array. Figure 2 In the drainable bowl cover, the paper layer 4 is combined with the PE resin layer 6. The paper layer 4 has a good adsorption effect on the release oil (i.e., the release agent layer 5). Therefore, the release agent layer 5 can be stably attached to the paper layer 4. When the paper layer 4 is combined with the PE resin, the paper layer 4 in the area where the release agent is applied has a relatively weak combined strength. In addition, a point array of adhesion areas is arranged in the area. As shown in the drawings (Figs. 1 and 2), the white round holes in the drawings are the point array. The point array is adhesively connected to the PE resin without affecting the function of the release oil. The point array provides a certain combined strength.
