Abstract
The utility model discloses a kind of shock resistance packing board, belong to cardboard and manufacture field.Comprise original paper layer, lower original paper layer, corrugated layer, upper tack coat and lower tack coat, upper original paper layer is by upper tack coat and bonding above corrugated layer, lower original paper layer is by bonding below lower tack coat and corrugated layer, corrugated layer comprises the upright trapezoidal corrugating media being arranged alternately with each other and the trapezoidal corrugating media that stands upside down, upright trapezoidal corrugating media and stand upside down and leave gap between trapezoidal corrugating media, between any two trapezoidal corrugating medias and in the Delta Region forming between the trapezoidal corrugating media of opposition, fill the stupefied paper web of cylindricality resilient tile, elasticity corrugation paper web is connected with three trapezoidal corrugating medias.When the utility model packing board externally impacts pressurized, its upright trapezoidal corrugating media and the trapezoidal corrugating media move toward one another of standing upside down, now trapezoidal between elasticity corrugation paper web can alleviate widely impulsive force, thereby internal memory article are protected effectively.The utility model also provides a kind of packing case that comprises this cardboard.
Description
Technical field
The utility model relates to a kind of packing board and packing case, is specifically a kind of shock resistance packing board and packing case, belongs to cardboard and manufactures field.
Background technology
Packing board is the common used material of current packing case, and therefore the advantages such as it possesses, and shock resistance is good, printing, lightweight, recyclable recycling are widely used in field of product packaging.Existing packing board consists of bonding in the middle of common top and bottom ply of paper and middle corrugated paper, can have the structures such as three layers, five layers.In use it is when being subject to surpassing proof pressure, and obvious deformation will occur packing board, and then affects the safety of interior items; Meanwhile, in the process of carrying, because force part is too concentrated, easily cause corrugated case integral body to be torn, damage interior items, cause waste of material, cannot be for as the packing of the sophisticated products such as electronic product, instrument and meter.In addition, existing packing board can not return in time original state after being subject to external impacts, has affected that it is follow-up to the protection of storing articles and overall appearance.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect of prior art, and a kind of sound construction is provided, and can effectively prevent the shock resistance packing board and the packing case that impact and recover in time.
In order to solve the problems of the technologies described above, the shock resistance packing board that the utility model provides, comprise original paper layer, lower original paper layer, corrugated layer, upper tack coat and lower tack coat, described upper original paper layer is by upper tack coat and bonding above corrugated layer, lower original paper layer is by bonding below lower tack coat and corrugated layer, described corrugated layer comprises the upright trapezoidal corrugating media being arranged alternately with each other and the trapezoidal corrugating media that stands upside down, described upright trapezoidal corrugating media and stand upside down and leave gap between trapezoidal corrugating media, between any two trapezoidal corrugating medias and in the Delta Region forming between the trapezoidal corrugating media of opposition, fill the stupefied paper web of cylindricality resilient tile, described elasticity corrugation paper web is connected with three trapezoidal corrugating medias.
In the utility model, described upper original paper layer and lower original paper layer outer surface are all coated with waterproof coating.
In the utility model, described upper and lower tack coat is hydroxypropul starch layer or polyvinyl alcohol layer.
In the utility model, the thickness of described hydroxypropul starch layer or polyvinyl alcohol layer is 0.25-0.35mm.
The invention also discloses a kind of packing case that adopts above-mentioned shock resistance packing board to make.
The beneficial effects of the utility model are: (1), the utility model corrugated layer adopt the upright trapezoidal corrugating media being arranged alternately with each other and the trapezoidal corrugating media that stands upside down to be arranged alternately with each other and form, upright trapezoidal and stand upside down between trapezoidal and be provided with gap, in the Delta Region forming between trapezoidal, fill the stupefied paper web of cylindricality resilient tile, at packing board during through external impact pressurized, its upright trapezoidal corrugating media and the trapezoidal corrugating media move toward one another of standing upside down, between now trapezoidal, elasticity corrugation paper web can be alleviated impulsive force widely, thereby internal memory article are protected effectively; Meanwhile, after pressurized, can restore to the original state in time; (2), upright trapezoidal corrugating media and the trapezoidal corrugating media that stands upside down intermeshing, promoted widely the tensile strength of packing board, in handling process, can effectively prevent that packing board from tearing.
Accompanying drawing explanation
Fig. 1 is the utility model shock resistance packing board structural representation;
Fig. 2 is corrugated layer structural representation in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model shock resistance packing board, comprise original paper layer 1, lower original paper layer 2, corrugated layer 5, upper tack coat 4 and lower tack coat 3, wherein go up original paper layer 1 bonding with corrugated layer 5 by upper tack coat 4 above, lower original paper layer 2 is bonding below with corrugated layer 5 by lower tack coat 3, upper tack coat 4 and lower tack coat 3 all adopt hydroxypropul starch layer or polyvinyl alcohol layer, its thickness is about 0.25-0.35mm, adopt amylan or polyvinyl alcohol as tack coat, its adhesion strength is high and environmental pollution is little, environmental protection.At upper original paper layer 1 and lower original paper layer 2 outer surfaces, be all coated with waterproof coating 5, so that packing board has water resistance, prevent from drenching with rain or making moist.
As shown in Figure 2, in the utility model, corrugated layer comprises the upright trapezoidal corrugating media 51 being arranged alternately with each other and the trapezoidal corrugating media 52 that stands upside down, upright trapezoidal corrugating media 51 and stand upside down and leave certain interval between trapezoidal corrugating media 52 wherein, to guarantee the enough cushion spaces when the pressurized; Between any two trapezoidal corrugating medias and in the Delta Region forming between the trapezoidal corrugating media of opposition, fill the stupefied paper web 53 of cylindricality resilient tile, elasticity corrugation paper web 53 is connected with three trapezoidal corrugating medias, when because of impact pressurized, elasticity corrugation paper web 53 can shrink in time and reduce, and realizes shock resistance and recovers object; Upright trapezoidal corrugating media 51 and stand upside down intermeshingly between trapezoidal corrugating media 52, can strengthen packing board tensile strength.
The packing case that adopts the utility model packing board to make, resistance to impact is good, and bearing strength is high, and facial tissue layer cohesive is good, is difficult for peeling off, and can effectively prevent the phenomenon of tearing that occurs in external impact and use procedure, and effectively protects the safety of connection with wrapping of piece.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not depart from the utility model principle, can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
