Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a degradable adhesive tape. Background Art

[0002] According to its function, tape can be divided into: high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cut tape. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to objects. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; and various polymers are widely used in modern times.

[0003] Tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. Among them, most of the tapes consumed in large quantities in express packaging are non-degradable tapes. On the one hand, the use of non-degradable tapes will cause serious environmental pollution. On the other hand, it will also make it difficult to recycle packaging boxes with non-degradable tapes, thereby increasing recycling costs. Therefore, there is an urgent need for a degradable tape to overcome the above-mentioned defects. Utility Model Content

[0006] Furthermore, the substrate layer is arranged on the top of the regenerated cellulose film, and the fiber layer is arranged on the top of the substrate layer.

[0007] Furthermore, the fiber layer includes grass fibers and cotton fibers, and the cotton fibers are arranged at the bottom of the grass fibers.

[0008] Furthermore, the thickness of the fiber layer is greater than the thickness of the substrate layer, the thickness of the substrate layer is less than the thickness of the regenerated cellulose film, and the thickness of the kraft paper is greater than the thickness of the regenerated cellulose film.

[0009] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:

[0010] The utility model winds and fixes the tape body by arranging a reel, and arranges a base material layer, which contains 30-50 parts of starch, 20-40 parts of vegetable gum, 5-20 parts of degradable fiber, 1.0-3.0 parts of coupling agent, 0.5-2.0 parts of plasticizer, 0.1-0.5 parts of lubricant, and 0.1-0.5 parts of stabilizer. The utility model arranges an adhesive layer, which contains 7-13 parts of gum arabic, 3-7 parts of guar gum, 2-4 parts of rosin, 2-4 parts of gelatin, and 110-250 parts of water. The cooperation of the base material layer and the adhesive layer greatly reduces the pollution to the environment caused by the large-scale use of the tape, and the utility model has the advantages of being degradable and having a good degradation effect, and solves the problem that most of the tapes used in express packaging are non-degradable tapes. The use of non-degradable tapes will cause serious environmental pollution on the one hand, and on the other hand, it will cause difficulty in recycling the packaging boxes bonded with the non-degradable tapes, thereby increasing the recycling cost.

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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 making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0018] In some embodiments, the substrate layer 212 is disposed on top of the regenerated cellulose film 213 , and the fiber layer 211 is disposed on top of the substrate layer 212 . More specifically, the degradation coefficient of the tape body 2 is increased by disposing the fiber layer 211 .

[0019] In some embodiments, the fiber layer 211 includes grass fiber 201 and cotton fiber 202, and the cotton fiber 202 is arranged at the bottom of the grass fiber 201. More specifically, the grass fiber 201 is one of the most common natural plant fibers, derived from cotton, and is widely used in textiles, clothing and other fields. It has good softness and breathability and is suitable for making summer clothes and home textile products. In addition, the properties of the grass fiber 201 determine that it can be harmlessly degraded to reduce pollution to the environment. By setting the cotton fiber 202, harmless degradation can be achieved, which meets environmental protection requirements.

[0020] In some embodiments, the thickness of the fiber layer 211 is greater than the thickness of the substrate layer 212, the thickness of the substrate layer 212 is less than the thickness of the regenerated cellulose film 213, and the thickness of the kraft paper 214 is greater than the thickness of the regenerated cellulose film 213. More specifically, by setting the regenerated cellulose film 213, the film is resistant to high temperatures, environmentally friendly, harmless, and convenient for writing, and can also meet the requirements of being pollution-free and degradable.

The grass fiber 201 is one of the most common natural plant fibers, which is derived from cotton and is widely used in textiles, clothing and other fields. It has good softness and breathability and is suitable for making summer clothes and home textiles. In addition, the nature of the grass fiber 201 determines that it can be harmlessly degraded to reduce pollution to the environment. The cotton fiber 202 can be harmlessly degraded to meet environmental protection requirements. The regenerated cellulose film 213 has high temperature resistance, is environmentally friendly and harmless, and is convenient for writing, and can meet the requirements of pollution-free and degradable.
