subject: Carton To Use The Process And The Solution - After Printing, Carton, Corrugated - Printing Industry [print this page] In the process of using cardboard boxes, there are two main problems: one, fat package or drum kits; two cartons of damage. We analyzed the causes are as follows:
One, the causes and (1) fat bag or drum pack
1. Corrugation poor choice A watt is the highest height, the same paper, although its performance under vertical pressure is good, but is subjected to pressure as B-and C-type. A carton of tiles on the product, in the transport process, the cartons will be horizontal and vertical vibration, packaging and carton boxes between the repeated shocks to the wall thinning appeared the phenomenon of fat bag or drum package.
2. Stacking of finished shovel board
Products in the finished product warehouse stacking, it is usually very high accumulation in general is high stack of two shovel board. Cartons in the stacking process, the carton, particularly the strength of the underlying case change is a "creep" process, which is characterized by relative stability in a considerable period of time load acting on the cartons, the boxes will be produced under static load continuous deformation, if the long-term to maintain static pressure, collapsed cardboard boxes will be damaged, so the most shovel-board stacking cartons lower tympanites often occurred, and was a part of the crush. Cartons by the vertical pressure, the central panel and the maximum deformation, there appears crease after crushing a conspicuous parabolic shape to. Corrugated box compression test proved that when the strength of the best Division four corners, the midpoint of the side, intensity of the worst. Therefore, the feet of the upper blade plate direct pressure in the middle of cardboard boxes, make boxes the middle of the formation of concentrated load, will cause rupture or permanent deformation carton. As the shovel plate gap still too wide to fall into the last corner of the carton, which can cause fat bag or cardboard drum package.
3. Does not determine the exact size of high-good Box
Soda carton boxes and boxes of high water tanks generally defined as the contents of the bottle bottle high with around 2mm, as cardboard boxes stacked, the longer withstand static load, and the transport process by the impact, vibration, bumps, to carton wall thinning, increased part height, making me much more high than the tall bottles, so make fat bag or carton drum package is more evident.
(B) a large number of damaged cartons mainly due to the following factors:
1. Improper size of carton box
Carton length, width and height dimensions of the damage relations with the larger carton. Carton size is generally installed according to the number of bottles and bottles of high to set. Box length is the length direction of the bottle a few bottle diameter, box width is the width direction the number of bottle diameter bottle, box is basically a bottle of high high. Four sides of the enclosure perimeter pressure load equivalent to support the entire carton wall, generally the longer the perimeter, the higher compressive strength, but increased in proportion. If the four sides of the perimeter too much, that the contents of the bottle a few more, FCL product gross weight on a large, high demands on the carton, the need for high compressive strength and bursting, to ensure the carton performance, otherwise the cartons easier to damage in the circulation phenomena that occur during. Market, 596mL 24 bottles of pure water tank damaged in all the boxes in the most, because of its greater gross weight, it is a single tile boxes, in the circulation process prone to breakage phenomenon.
Of the carton length, width and the same case, the height of the compressive strength of a larger air box. Four sides of the carton under the same circumference as the carton height, the compressive strength lower, down about 20%.
2. Fail to meet requirements the thickness of corrugated board
Corrugated during use as will be wear and tear, making up less than the thickness of corrugated board requirements, so the low compressive strength of cartons, the cartons will fall.
3. Deformation of corrugated cartons
Produce corrugated cardboard deformation itself is relatively soft, low surface strength, rigidity is also low, with such a corrugated cardboard box compressive strength, puncture strength is also small.
