Description
Technical Field
The utility model relates to the field of postal express delivery and packaging, in particular to a buffer sheet and a packaging bag.
Background
Currently, a buffer sheet which is wrapped or filled on the outer surface of an object and directly plays a role in buffering mainly comprises: bubble film structure, plastic foam, etc., which are not environment-friendly.
Another application is: the paper sheet is die-cut to form a plurality of arranged knife edges, and after the cut paper sheet is stretched, the knife edges are wrinkled and bent to form a three-dimensional net-shaped structure, namely the buffer pad. The buffer pad can be directly wrapped on the outer surface of an object to play a role in buffering, but the cut paper sheet needs to be stretched, most of the paper sheet is stretched manually in the stretching process, and in the manual stretching process, only one part of the die-cut paper is stretched and the other part of the paper sheet is not stretched easily due to uneven force application of the hands at the pulling points; or the die-cut paper is damaged due to overlarge pulling force when being stretched. Although the packaging bag is produced using the three-dimensional grid structure as the buffer layer, the packaging bag is produced by requiring a paper sheet to be set in the packaging bag in a stretched state and not to be retracted, which results in a complicated production process of such packaging bag.
In addition, the increase in thickness of the stretched three-dimensional grid structure compared to the paper sheet before stretching is mainly due to the wrinkling and bending of the cuts; the size of the buffering capacity of the three-dimensional grid structure depends on the length and angle of the notch wrinkling and bending, and the strength is general for paper materials, so that the buffering effect is poor, especially when stacking and pressing under heavy pressure, the bending and wrinkling positions may be directly caused to collapse, and the buffering effect is further greatly reduced.
Disclosure of Invention
The utility model aims to provide a buffer sheet, which aims to solve the technical problems that the existing buffer sheet is not environment-friendly or is easy to damage in the stretching process and has poor buffer effect.
The present utility model provides a buffer sheet, comprising:
a first face;
a second face, the second face being connected to the first face;

the first surface, the second surface and the buffer particles are all degradable paper materials, and the buffer particles comprise at least one of the following: paper tube, cut paper tube, rubbed paper strip and paper ball.
In this embodiment, the paper buffer particles are filled between the first surface and the second surface, and when the buffer sheet is wrapped by the wrapping material or filled outside the wrapper, the buffer particles have elasticity when the buffer sheet is subjected to external pressure, and can absorb part of impulse, thereby achieving the purpose of protection. Especially when the buffer particles are paper tubes, the walls of the paper tubes bear pressure deformation, and the buffer particles have a better buffer effect.
Wherein, a plurality of buffer particles are arranged between first face and second face, can evenly arrange fixedly through the fixative that sets up to guarantee that the homoenergetic obtains supporting effect on first face and the whole plane of second face.
Another object of the present utility model is to disclose a packaging bag, wherein the cushion sheet is made of the packaging bag.
The packaging bag manufactured by the buffer sheet is used, after a package is placed inside the packaging bag, both sides of the package are wrapped by the buffer sheet, and buffer particles inside the buffer sheet can play a role in buffering, so that the package is protected.
The buffer sheet and the packaging bag are made of paper materials, and can be naturally degraded after being discarded, so that the buffer sheet and the packaging bag are environment-friendly; in addition, compared with the existing three-dimensional grid structure made of paper sheets, the three-dimensional grid structure does not need stretching, and is easy to operate; when the packaging bag is manufactured, the buffer particles can be fixed only by coating the fixing agent on the first surface or the second surface and throwing or spraying the buffer particles on the first surface or the second surface, and the manufacturing process is relatively simple.

Detailed Description
The utility model is further illustrated and described below in conjunction with the specific embodiments and the accompanying drawings:
referring to fig. 1 to 3, the present utility model discloses a buffer sheet, which includes: first side 10
And a second face 20 and buffer particles 30.
Wherein the second face 20 is connected to the first face 10; the buffer particles 30 are disposed between the first surface 10 and the second surface 20, a side surface of the first surface 10 and/or the second surface 20 facing the buffer particles 30 is coated with a fixing agent, and the buffer particles 30 are connected with the first surface 10 and/or the second surface 20 through the fixing agent.
In the present utility model, the first surface 10, the second surface 20 and the buffer particles 30 are all made of degradable paper materials, and the buffer particles 30 include at least one of the following: a paper tube 31, a rubbed paper strip 32, a paper ball 33 and a cut paper tube 34.
The cut paper tube 34 is formed by cutting the paper tube 31 along the extending direction and the vertical extending direction, the cut paper tube 34 is half of the paper tube 31, the outer circumferential surface is a curved arch structure, and when the cut paper tube 34 is stressed, the curved arch structure can provide better supporting function.
In this embodiment, the paper buffer particles 30 are filled between the first surface 10 and the second surface 20, and when the buffer sheet is wrapped as a wrapping material or filled outside the package, the buffer particles 30 have elasticity when the buffer sheet is subjected to external pressure, and can absorb part of the impulse, thereby achieving the protection purpose. Particularly, when the buffer particles 30 are paper tubes 31, the walls of the paper tubes 31 are subjected to pressure deformation, so that a better buffer effect is achieved.
When the buffer particles 30 are paper tubes 31, paper materials with different elastic coefficients can be used for manufacturing the buffer sheet, and the plurality of paper tubes 31 with different elastic properties can enable the buffer sheet to have a better buffer effect. For example, one paper tube 31 has a stronger elastic strength but is smaller in size, and the other paper tube 31 has a smaller elastic strength, more flexible but larger in size; when the buffer sheet receives an external force, the paper tube 31 having a slightly smaller elastic dimension and a larger elastic dimension first receives the impact and changes the thickness of the buffer sheet, and then the force acts on the other paper tube 31 having a smaller elastic dimension and a larger elastic strength, the paper tube 31 further reduces the effect of the external force on the buffer sheet, and the buffer particles 30 having two different elastic strengths and sizes are mixed and filled between the first face 10 and the second face 20, so that the buffer effect of the buffer sheet can be improved.
In the present embodiment, as shown in fig. 2, the paper tube 31 or the cut paper tube 34 has the same length and diameter, and is preferably set to a size of 2-30 mm. When the paper tube 31 is disposed between the first surface 10 and the second surface 20, since the length and the diameter of the paper tube 31 are the same, there is a more flexible manner of disposing, for example, a plurality of paper tube 31 particles are directly laid between the first surface 10 and the second surface 20, a part of the paper tube 31 is in an erected state, that is, the wall of the paper tube 31 is vertical or inclined to the first surface 10 or the second surface 20, and a part of the paper tube 31 is in a horizontal state, that is, the wall of the paper tube 31 is parallel to the first surface 10 or the second surface 20, in which the erected paper tube 31 exhibits a stronger elastic strength and the horizontal paper tube 31 exhibits a smaller elastic strength, and the buffering performance of the entire buffer sheet can be improved by realizing a combination of a plurality of different elastic strengths by only one kind of buffering particles 30.
In one embodiment, the buffer particles 30 in the buffer sheet are composed of the paper tube 31, the paper strip 32 or the paper ball 33 mixed together, and the plurality of buffer particles 30 in the buffer sheet have different identical lengths, diameters and elasticity.
In the present embodiment, it is preferable that the buffer particles 30 having smaller elastic strength have a length or diameter larger than those of the buffer particles 30 having larger elastic strength, in which case, when an external force acts on the buffer sheet, the buffer particles 30 having larger diameter or length receive the impact first, and the buffer particles 30 having larger elastic strength in a smaller size receive the impact again with a reduced external force, so that the buffer protection can be better performed without causing direct impact to the buffer particles 30 having larger elastic strength due to an excessive external force, thereby causing the breakage of the first face 10 or the second face 20.
Wherein, a plurality of buffer particles 30 are arranged between the first surface 10 and the second surface 20, and can be uniformly arranged and fixed by the fixing agent, and the buffer particles 30 are relatively uniformly arranged between the first surface 10 or the second surface 20 at random, so that the whole planes of the first surface 10 and the second surface 20 can obtain supporting and buffering effects.
Wherein edges of the second surface 20 and the first surface 10 are fixed to each other, so that a closed space is formed between the first surface 10 and the second surface 20. In this embodiment, the airtight space is sealed with a gas, where the gas includes air or other gases, and when the force acts on the buffer sheet, on one hand, the buffer particles 30 located between the first surface 10 and the second surface 20 can absorb the force to achieve a buffering effect, and on the other hand, the gas in the interior also can provide a certain buffering effect, so that the force on the whole plane of the buffer sheet is relatively uniform, and the situation that the first surface 10 or the second surface 20 is broken does not occur.
In the present utility model, the fixative is preferably a degradable glue extracted from plant pulp, such as a resin fixative, so that the fixative can be degraded together with the paper first side 10, second side 20 and buffer particles 30 after the buffer sheet is discarded, which is more environment friendly.
As shown in fig. 4 to 6, in the present utility model, a package bag is also disclosed, which is made of a buffer sheet, and when the package bag is made of the buffer sheet, there are two manufacturing processes corresponding to two different structures of the package bag.
First, as shown in fig. 4, the buffer sheet is provided with a folding line, the folding line is located at the center of the buffer sheet, the packaging bag comprises a bag bottom, the bag bottom is overlapped with the folding line, the buffer sheet is folded along the folding line to form the bag bottom, and two side edges of the buffer sheet perpendicular to the folding line are fixed with each other.
In this case, the buffer sheet is folded to form a bag bottom, and the two sides of the buffer sheet are sealed to form a packaging bag with an opening at one side, a sealing structure 40 is stuck near the outer side surface of the reserved opening, and the opening can be sealed after the sealing structure 40 is folded and stuck, so that a sealed bag body is formed.
Second, as shown in fig. 5, the buffer sheet has two sheets, two sheets of the buffer sheet are overlapped with each other, and a bottom edge of the two sheets of the buffer sheet and both side edges perpendicular to the bottom edge are fixed to each other to form the package bag.
In this manner, the bag body is formed by edge sealing three sides of the buffer sheet, and the opening on one side is reserved.
When the packaging bag is manufactured in the utility model, the buffer particles 30 can be fixed by only coating the fixing agent on the first surface 10 or the second surface 20 and throwing or spraying the buffer particles 30 on the first surface 10 or the second surface 20, so that the manufacturing process is relatively simple.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the scope of the present utility model, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
