[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The terms "first," "second," and the like in the specification and claims of the present invention are used to distinguish similar objects and are not intended to describe a particular order or precedence. It should be understood that such terms are interchangeable where appropriate, so that the embodiments of the present invention can be implemented in sequences other than those illustrated or described herein. Furthermore, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the connected objects are in an "or" relationship.

[0035] like Figures 1 to 4 As shown, the packaging tape of an embodiment of the present invention includes: a carrier 10, a tape ring 20, and a waterproof layer. The carrier 10 is cylindrical and made of paper. The carrier 10 has a cavity 11 extending along the axis of the carrier 10. The cavity 11 is cylindrical. The tape ring 20 is composed of a tape layer wrapped around the outer periphery of the carrier 10. The tape layer is wound in multiple layers. The tape ring 20 is annular and can be a transparent layer. The axis of the tape ring 20 can coincide with the axis of the carrier 10. The waterproof layer can include a first waterproof layer 31 and a second waterproof layer 32. The first waterproof layer 31 is provided at the edge of the opening of the cavity 11 to prevent the edge of the opening of the cavity 11 from getting wet. The inner wall of the cavity of the carrier 10 has a second waterproof layer 32 to prevent the inner wall of the cavity of the carrier 10 from absorbing water and getting damp. The waterproof layer can isolate the carrier 10 from the external environment and is not easily affected by moisture. The waterproof layer can protect the carrier 10.

[0036] The first waterproof layer 31 and the second waterproof layer 32 can be elastic layers that provide a cushioning effect, preventing hand injuries and discomfort when gripping the carrier. The second waterproof layer 32 can have bumps distributed on its surface to prevent slippage and increased friction when sweating or wet. The first waterproof layer 31 and the second waterproof layer 32 can be transparent plastic films.

[0037] The packaging tape of the embodiment of the present invention can effectively prevent the paper carrier from getting damp by providing a waterproof layer on the paper carrier. During the use or placement of the tape, when encountering water or a humid environment, the paper carrier is not easily damp, thereby ensuring the strength of the paper carrier, making the tape carrier not easily damaged or deformed when subjected to external forces, and at the same time preventing separation or deformation between the tape layers due to damage or deformation of the carrier, thereby facilitating use by users.

[0038] Optionally, the tape layer is a degradable material layer, which is beneficial to environmental protection and reduces environmental pollution.

[0039] Optionally, the degradable material layer is a polylactic acid layer, a starch plastic layer or a photodegradable plastic layer, which is beneficial to environmental protection and reduces environmental pollution.

[0040] Optionally, the first waterproof layer 31 is connected to the second waterproof layer 32 , and the first waterproof layer 31 and the second waterproof layer 32 can be integrally formed to increase sealing performance and facilitate processing and manufacturing.

[0041] Optionally, the first waterproof layer 31 and the second waterproof layer 32 are transparent layers, and the inner side wall of the cavity of the carrier 10 can be provided with a logo or pattern to facilitate observation of the logo or pattern printed on the carrier.

[0042] In some embodiments, at least one of the first waterproof layer 31 and the second waterproof layer 32 is a plastic layer or a rubber layer. For example, the first waterproof layer 31 and the second waterproof layer 32 are plastic layers or rubber layers.

[0043] In some embodiments, as Figures 1 to 4 As shown, the tape further includes a protective layer 40, which is annular and covers the end surface of the tape loop 20. The end surface of the tape loop 20 is perpendicular to the axis of the tape loop 20. The adhesive at the edge of the tape layer on the end surface of the tape loop 20 is exposed, making the end surface of the tape loop 20 have a certain degree of adhesion and easily absorb dust, debris, fiber filaments, etc. The protective layer 40 can protect the end surface of the tape loop 20.

[0044] Alternatively, as Figures 2 to 3As shown, the protective layer 40 includes multiple protective films 50 in an annular shape. The centers of the multiple protective films 50 coincide, the edges of adjacent protective films 50 touch, and the axis of the protective film 50 coincides with the axis of the tape ring 20. The protective films 50 protect the end surface of the tape ring 20. During use, the protective film 50 on the outermost ring can be peeled off. As the number of tape layers decreases, the thickness of the tape ring 20 decreases, and the protective film 50 near the outermost ring can be removed, and the removal process continues inward. Each time a layer of protective film 50 is peeled off, only the edge of the portion of the tape layer to be used is exposed, facilitating the use of the tape layer while also protecting the edges of the remaining tape layers.

[0045] Alternatively, as Figure 4 As shown, the protective layer 40 is provided with a plurality of annular tear lines 60, the centers of the plurality of tear lines 60 coinciding with each other, and the axes of the tear lines 60 coinciding with the axis of the tape loop 20. The tear lines 60 allow the protective layers of different loops to be peeled off. The outermost loop of the protective layer can be removed by first tearing off the tear line 60 located on the outermost loop, leaving only the edge of the tape layer to be used exposed, facilitating the use of the tape layer while protecting the edges of the remaining tape layers.

[0046] Optionally, the protective layer 40 is a transparent plastic layer.

[0047] Optionally, the protective layer 40 is connected to the edge of the tape layer by adhesive bonding, and is only connected by adhesive bonding of the edge of the tape layer, without the need to apply additional adhesive.

[0048] Optionally, thickness scale lines are provided on the protective layer 40 , and the thickness scale lines are distributed along the radial direction of the protective layer, so that the remaining thickness of the tape layer can be observed.

[0049] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, all of which are within the protection of the present invention.
