A kind of packaging board that contains the cylindrical structural core paper
Technical field
The present invention relates to a kind of cardboard, relate in particular to a kind of packaging board that contains the cylindrical structural core paper.
Technical background
Existing packing board generally all is to use corrugated board, it generally is made of facial tissue, V-arrangement corrugating medium, lining paper, this traditional corrugated board ubiquity defectives such as shock-absorbing capacity is not good enough, intensity is lower, can only be used for the packing of lightweight product, and not be suitable for the packing of Heavy Product.Reason is, when carrying out the Heavy Product packing, especially at packing case during with the collision of external hard plastic environment, the outer surface of packing board can distortion of first mate's degree or damage, causes the product protection dynamics in the packing case not goodly, causes the distortion or the damage of product.
Summary of the invention
The object of the invention provides a kind of packaging board that contains the cylindrical structural core paper that possesses comfort cushioning performance and higher-strength simultaneously.
Technical scheme of the present invention is: comprise outer facial tissue, core paper, nexine facial tissue, it is characterized in that: described core paper is the compound core paper that is made of jointly cylindrical structural core paper and V-type corrugating medium, be provided with barrier paper between two kinds of core papers, described outer facial tissue, nexine facial tissue are bonded in two lateral surfaces of compound core paper respectively.
The triangle the top of the horn of described V-arrangement corrugating medium faces the central shaft of cylindrical structural core paper.
The present invention is because the triangular structure of V-arrangement corrugating medium is a kind of rigid structure, and stressed back is highly stable, thereby makes combination board have very high hardness; And the cylindrical structural core paper presents level and smooth nonlinear organization, when this structure was subjected to necessarily impacting, the response of structure impact also can present non-linear, made its distortion a stable region occur, even have very big impact also only can produce very little distortion, thereby have good shock-absorbing capacity; The present invention combines the high-strength characteristic of good shock-absorbing capacity of cylindrical structural core paper and V-arrangement corrugating medium, is not only applicable to the packing of lightweight product, also is applicable to the packing of Heavy Product, has expanded range of application greatly.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is user mode figure embodiment illustrated in fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises outer facial tissue 1, core paper, nexine facial tissue 3, described core paper is the compound core paper that is made of jointly cylindrical structural core paper 4 and V-type corrugating medium 5, be bonded with barrier paper 2 between nexine facial tissue 4 and the V-type corrugating medium 5, described outer facial tissue 1, nexine facial tissue 3 are bonded in two lateral surfaces of compound core paper respectively.
The triangle the top of the horn of described V-arrangement corrugating medium 5 faces the central shaft of cylindrical structural core paper 4.
With reference to Fig. 2; during use; product 6 is placed on nexine facial tissue 3 surfaces; near circular configuration core paper 4 one sides, when vibration taking place and impact, product produces the one-period active force to nexine facial tissue 3 under the gravity effect; because cylindrical structural core paper 4 impact have certain abirritation; make combination board have a hysteresis effect, and cylindrical structural core paper 4 has recovered deformation before another impacts arrival, can protect product to avoid shock effect effectively with respect to shock response.Opposite side is a V-arrangement corrugating medium 5, and this structural strength is bigger, can resist powerful external static pressure, can guarantee that packing case can not damage content because of crimp.
