Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, in particular to a green and environmentally friendly food packaging material. Background Art

[0002] Green packaging materials refer to materials or materials that can save resources and energy during production, use, scrapping, recycling and reuse, and can be quickly degraded or reused naturally after being discarded, without destroying the ecological balance. They are widely available, low in energy consumption, easy to recycle and have a high recycling rate. Common green packaging materials include degradable plastics and natural biomolecular materials.

[0003] When food needs to be packaged, green and environmentally friendly food packaging materials need to be used to package the food.

[0004] After being discarded, existing green and environmentally friendly food packaging materials will be degraded or recycled in order not to damage the ecological environment. However, in order to facilitate food packaging, the internal sealing films of existing green and environmentally friendly food packaging materials are all integrated, which is not convenient for the environmentally friendly materials to be quickly degraded.

[0005] Moreover, when the existing green and environmentally friendly food packaging materials are used to package food, the cover plate on the top is directly engaged with the green and environmentally friendly food packaging materials, so that it is easy to fall off during transportation, resulting in damage to the food inside. Summary of the invention

[0006] The purpose of the utility model is to provide a green and environmentally friendly food packaging material to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a green and environmentally friendly food packaging material, comprising a protective layer and a non-woven paperboard layer located on the inner wall of the protective layer; a sealing layer is provided inside the non-woven paperboard layer, a reinforcement strip is provided on the outer wall of the protective layer, a cover plate is provided on the top of the protective layer, a pull rod is integrally formed with the bottom of the cover plate, an end of the pull rod away from the cover plate is connected to a limit ring by a snap-fitting form, and honeycomb holes are opened on the sealing layer; the sealing layer is used to seal the connection between the non-woven paperboard layers.

[0008] Preferably, the sealing layer is connected to the corners of the non-woven paperboard layer by gluing, and the inner wall of the protective layer is connected to the outer wall of the non-woven paperboard layer by gluing.

[0009] Preferably, the honeycomb holes are distributed at equal intervals on the sealing layer.

[0010] Preferably, the reinforcement strip is connected to the four corners of the protective layer by adhesion, and the reinforcement strip wraps the four corners of the protective layer.

[0011] Preferably, one side of the limiting ring is integrally formed with the reinforcement strip, and limiting rings are arranged around the reinforcement strip.

[0012] Preferably, the protective layer is provided with dotted holes, and the dotted holes are distributed at equal intervals on the protective layer.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model can improve the degradation efficiency of green and environmentally friendly food packaging materials by setting honeycomb holes and dotted holes. After the green and environmentally friendly food packaging materials are used up, the protective layer and the non-woven paperboard layer are torn through the dotted holes, so that the volume of the green and environmentally friendly food packaging materials becomes smaller. At the same time, the sealing layer only seals the corners of the non-woven paperboard layer, and its volume is relatively small. During the degradation process, the sealing layer is no longer integrated due to the honeycomb holes, and can be degraded outwards through the honeycomb holes and inwards at the edges. At the same time, the protective layer and the non-woven paperboard layer with reduced volumes will also be rapidly degraded through the edges, effectively improving the degradation efficiency.

[0015] Second, the utility model can seal the green and environmentally friendly food packaging materials by setting a pull rod and a limit ring. After placing the food inside the non-woven paperboard layer, the cover is covered, and then one end of the pull ring is pulled to engage with the inside of the limit hole. One end of the pull ring is larger than the through hole on the limit hole. The limit ring limits the cover through the pull rod, preventing the cover from being opened by collision when transporting food through the green and environmentally friendly food packaging materials, thereby preventing food from being damaged, thereby reflecting the practicality of this device.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 , a green and environmentally friendly food packaging material comprises a protective layer 1, a non-woven paperboard layer 8 located on the inner wall of the protective layer 1; a sealing layer 6 is arranged inside the non-woven paperboard layer 8, a reinforcement strip 3 is arranged on the outer wall of the protective layer 1, a cover plate 2 is arranged on the top of the protective layer 1, a pull rod 4 is integrally formed at the bottom of the cover plate 2, and the end of the pull rod 4 away from the cover plate 2 is connected to a limit ring 5 by snapping, and a honeycomb hole 7 is opened on the sealing layer 6; the sealing layer 6 is used to seal the connection between the non-woven paperboard layer 8, when the green and environmentally friendly food packaging material is used, the protective layer 1 and the non-woven paperboard layer 8 are torn through the dotted line hole 9, so that the volume of the green and environmentally friendly food packaging material becomes smaller, and at the same time, the sealing layer 6 only seals the corners of the non-woven paperboard layer 8, and its volume is small. During the degradation process, the sealing layer 6 is no longer integrated due to the honeycomb hole 7, and can be degraded outward through the honeycomb hole 7 and degraded inward at the edge. At the same time, the protective layer 1 and the non-woven paperboard layer 8 with reduced volume will also be rapidly degraded through the edge, which effectively improves the degradation efficiency.

[0023] Specifically, the sealing layer 6 is connected to the corners of the non-woven paperboard layer 8 by adhesion, and the inner wall of the protective layer 1 is connected to the outer wall of the non-woven paperboard layer 8 by adhesion.

[0024] Through the above technical solution, the sealing layer 6 can be degraded from the inside out and from the outside in at the same time through the honeycomb holes 7. The sealing layer 6 is made of PET film material, the protective layer 1 is made of natural fiber material, and the non-woven paperboard layer 8 is made of non-woven paper material, which has certain waterproof performance.

[0025] Specifically, the honeycomb holes 7 are distributed at equal intervals on the sealing layer 6 .

[0026] According to the above technical solution, when food is usually packaged, a sealing film is provided on the inner wall of the green and environmentally friendly food packaging material to prevent water in the food from flowing to the outside, but the film is integrated and degrades slowly during degradation.

[0027] Specifically, the reinforcement strips 3 are connected to the four corners of the protective layer 1 by adhesion, and the reinforcement strips 3 wrap the four corners of the protective layer 1.

[0028] Through the above technical solution, the reinforcement strip 3 is used to support the green and environmentally friendly food packaging material to prevent it from being squeezed by external objects during transportation and causing deformation.

[0029] Specifically, one side of the limiting ring 5 is formed integrally with the reinforcement strip 3 , and the limiting ring 5 is arranged around the reinforcement strip 3 .

[0030] Through the above technical solution, the end of the pull ring connected to the cover plate 2 is smaller, and the other end of the pull ring is larger than the end connected to the cover plate 2, so that it can be engaged with the inside of the limit ring 5 to prevent the pull rod 4 from moving to the outside at will. Pull rods 4 are arranged around the cover plate 2.

[0031] Specifically, the protective layer 1 is provided with dotted holes 9 , which are evenly spaced on the protective layer 1 , and the honeycomb holes 7 are octagonal.

[0032] Through the above technical solution, the dotted holes 9 are used to tear the external protective layer 1 and the non-woven paperboard layer 8, so that the protective layer 1 and the non-woven paperboard layer are no longer integrated, and the edge area of ​​the protective layer 1 and the non-woven paperboard layer is increased, so that they can be quickly degraded through the edges.

[0033] When in use, first, after the use of the green and environmentally friendly food packaging material is completed, the protective layer 1 and the non-woven paperboard layer 8 are torn through the dotted hole 9 to reduce the volume of the green and environmentally friendly food packaging material. At the same time, the sealing layer 6 only seals the corners of the non-woven paperboard layer 8, and its volume is relatively small. During the degradation process, the sealing layer 6 is no longer integrated due to the honeycomb holes 7, and can be degraded outwardly through the honeycomb holes 7 and degraded inwardly at the edges. At the same time, the protective layer 1 and the non-woven paperboard layer 8 with reduced volumes will also be rapidly degraded through the edges. After placing the food inside the non-woven paperboard layer 8, cover the cover 2, and then pull one end of the pull ring to engage with the inside of the limiting hole. One end of the pull ring is larger than the through hole on the limiting hole. The limiting ring 5 limits the cover 2 through the pull rod 4, which prevents the cover 2 from being opened by collision when the food is transported through the green and environmentally friendly food packaging material, causing damage to the food, and the work can be completed.
