The two watt calcium of one side is moulded corrugated case
Technical field
The utility model relates to a kind of corrugated case, relates in particular to the two watt calcium of a kind of one side and moulds corrugated case.
Background technology
Corrugated case is a kind of good packed and transported part, because its recyclable environmental protection is liked by the people, but in chemical industry, heavy type or long-term packaging and storing, the phenomenons such as the easy bulge of carton, the bag that collapses, carton cracking.According to mechanics principle and corrugated case compression test, be subject to pressure break deformation situation, in corrugated case pressurized when fission,, center outward bulge is opened, and then place, the upper and lower two ends of carton height starts crack, and carton is impaired, bulk strength and destroyed.But hygroscopic character and moisture resistance are the weaknesses of full paper wrapper.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and two layers of corrugated layer that form carton adopt calcic-plastic composite material to make, and improve its compressive strength and flat crushing strength, can carry out heavy wrapping; In carton, ply of paper adopts calcic-plastic composite material, improves its water-proofness and exposes intensity, can carry out the packed and transported of the products such as aquatic products and thin dish; Facial tissue adopts craft paper or white board, can carry out on carton surface fineness printing, retains the printability of carton and stacking skid resistance; Middle core paper adopts craft paper, improve itself and the bond strength of two layers of corrugated layer, and the one side reducing costs pair watt calcium is moulded corrugated case.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The two watt calcium of a kind of one side is moulded corrugated case, comprise casing, described casing comprises facial tissue layer, corrugated layer, laminboard layer and inner ply of paper, described facial tissue layer, corrugated layer, laminboard layer, corrugated layer and inner ply of paper are bonded in order mutually, described corrugated layer and the material of inner ply of paper are respectively calcium and mould, and described facial tissue layer and the material of laminboard layer are white board or craft paper.
As preferably, the stupefied type of two layers of corrugated layer is symmetry or mal-distribution.
This structure can be carried out larger weight or be had the packing of waterproof requirement product, has powerful flat crushing strength, and exquisite pattern printing can be carried out in its surface, and its product degradable reclaims.
Therefore, the two watt calcium of one side of the present utility model is moulded corrugated case, and structural strength is high, and suitability is strong, is convenient to packing and transportation, has certain water resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the two watt calcium of a kind of one side is moulded corrugated case, comprise casing 1, described casing 1 comprises facial tissue layer 2, corrugated layer 3-1,3-2, laminboard layer 4 and inner ply of paper 5, described facial tissue layer 2, corrugated layer 3-1, laminboard layer 4, corrugated layer 3-2 and inner ply of paper 5 are bonded in order mutually, described corrugated layer 3-1, the material of 3-2 and inner ply of paper 5 is respectively calcium and moulds, and described facial tissue layer 2 and the material of laminboard layer 4 are white board or craft paper.Two layers of corrugated layer 3-1, the stupefied type of 3-2 is symmetry or mal-distribution.
