What are the standards for carton boxes?
Compressive strength of carton and its influencing factorsThe compressive strength of the carton is many goods packaging requirements of the most important quality index, the test will be placed on the two plate corrugated carton, carton crushing pressure to the pressure, the compressive strength of the carton, denoted by KN.
1, the printing quality, printing pattern: handwriting clear, consistent color, bright light; printing position error box does not exceed 7mm, the box is not more than 4mm;2, sealing quality: no holes around the box, the box lid closed, no staggered and off the seam;3 dimensional tolerances: box diameter and design tolerances should be kept in the big box small box + 5mm, + 3mm, basically the same size;4, fold the number of fold: corrugated box shake lid opened, 180 degrees, reciprocating folding more than 5 times, the one or two types of box surface and inner layer, and three types of box, the total length of cracks in the box is not greater than 70mm;In addition, requirements for joining specifications, neat edges, no overlapping angles, and no obvious damage or stains are allowed on the box surface
Six angle drum turning testPut the carton into the six corners revolving drum with the impact plate, rotate according to the specified number of revolutions and times, and then check the damage of the goods and cartons.The above dynamic experiments are destructive and improve the resistance to damage of cartons and commodities by using cushion linings, partitions or other protective measures in the packaging of goods. In addition, some cartons need to be tested for spraying, weather resistance, etc., according to the contract agreement between the two parties.
