Shenzhen Longfa carton factory   

        where there is Ping
selection principle of carton factory carton factory in Longgang Henggang Shajing carton factory carton factory
corrugated boxes in the selection of corrugated carton must first take into account the nature of the product, weight, storage conditions and circulation environment, secondly should be designed according to the shockproof packaging design principle and design method of corrugated carton, also follow the relevant standards, such as packaging of export commodities to meet international standards or requirements of foreign, and through the relevant tests, so the corrugated packaging selection generally should note the following points.
: corrugated cardboard corrugated type   corrugated type, according to the corrugated high for A, B, C, E four class, has different mechanical properties of different corrugated cardboard. A type of corrugated cardboard plane the highest pressure, high compressive strength, type B on the contrary, plane stress, C type vertical pressure, parallel pressure and buffer force are better; the thickness of corrugated cardboard, type A maximum, C type, B type again, E minimum, due to the paper board processing bending the small thickness is easy, therefore, the B shape is widely used for compressive strength of corrugated box for the requirements of the packaging case. According to the different mechanical properties of corrugated cardboard, single-sided corrugated carton with A or C type as well, double corrugated box with A, B type or B type C combination is appropriate, close to the outer surface of the B type, can play the anti shock effect. A, type B or B, C type combination, can improve the physical mechanical properties from the comparison of the carton; printability, B type and C type are conducive to printing.  
the tile turn carton box; under the premise of ensuring the carton quality, should try to save the cost of carton processing materials and packaging. For example. Volume in the same box, using a long: the height and the width of the material is 2:1:2, ratio of 1:1:1 and the material. Therefore, should try to avoid using the square box. Take care of by products on the box volume rate, box on the truck, train compartment volume utilization and storage transport pumping stacking stability.
