Whether it is an antistatic ton bag, a container bag or a woven bag, there is a standard for the height and method of falling. In the international standard of anti-static ton bag, the drop test methods for ton bags are as follows: compared with the national standard, the bottom of the GB falls 1.2 meters, that is, longitudinal drop. At the same time, the horizontal and lateral direction falls to 1.2 meters. Each bag falls only once in flat, lateral and longitudinal, and three bags are circulate. The European standard stipulates that the bottom falls 1.2 meters high, that is, the vertical drop, the mouth of the bag facing down. At the same time, the level of flat to fall 1.6 meters high, drop two times with the front of the bag, and fall two times with the back side of the bag. The leveling is 4 times and is 1.6 meters high, so the required bag strength is much higher than that of the country. The international standard drop test mode for ton bags, the international standard ISO 23560:2008 "bulk food polypropylene ton bag", describes the structure of 50 tons or 25 kilograms ton bags of capacity antistatic, their size and the experimental method suitable for long-term storage and transportation in bags. This international standard stipulates that the polypropylene (PP) ton bag, which is suitable for transporting and storing food such as grain, sugar and beans.   

2, discussion on drop test of international standard antistatic ton bag

The antistatic ton bag international standard and the European standard drop the same way, stipulates the bottom or the tail falls falls 1.2 meters height, namely the longitudinal drop, the sealed bag mouth downward. At the same time, the level of falling or falling down 1.6 meters high, falling two times with the front of the bag, and falling two times with the back side of the bag. The horizontal direction is 4 times and is 1.6 meters high, so it is understandable not to do lateral fall.

International standard ton bag filling test specified value should be within 2% of the test bag filling amount ". However, the standard does not specify the specific filling coefficient.

Summary: the fall test of the international standard ton bag "bulk food polypropylene ton bag" is to check the bag breaking situation. Including the bag already made of the seal, excluding the downstream enterprise after the loading of material seal.

The standard stipulates that:

(1) test bag filling amount: a ton bag should be filled with the food it needs, and if there is no condition, find a kind of similar material filling bag. The test value for the filling of the food should be within 2%.

(2) the fall test should be carried out on three tons of bags and should include the following order:

1) tail fall: a ton of bags must fall from the height of 1.2m to the bottom of the bag.

2) straight down: a ton of bags must fall from the 1.6m altitude, fall one plane for the first two times, and the other two fall on the other plane.

(3) through the drop test standard: every fall must not break or leak out the material. Slight leakage, for example, from the tail and pinhole of the suture, if there is any influence, if the ton bag is improved, no more leakage will occur, and it is not considered to be unqualified.
