A word about Grain Bag Quality

It is important to make sure you choose the right grain bag if you plan to be successful in grain bagging this year. There are lots of bags out on the market and we strive to provide you with the best bags because we believe we sell the best grain bagging system, the Richiger Grain Bagging Systems- so we would not want to short our customers on the bags. We provide Plastar grain bags in various mils and lengths, for both 9 and 10 ft baggers. Our bags have been tested by the State of Missouri in order to determine the actual mil thickness and quality of bags. Some customers choose to go by price only when choosing grain bags, but this can be risky if the quality is low. We try to give our customers the best quality bags at a reasonable price so that you can rest assured that your grain is safe inside our bags. Take a look below at what Richiger has to say about bag quality:


"All storage bags are not made equal. Although some bags are still manufactured using a single thick layer of plastic, today’s industry standard is the three-layer, co-extruded polyethylene tube, and the norm is one that is 9 ft. (2.70 meters) in diameter and 200 ft. (60 meters) in length, capable of holding about 200 tons of grain (some 8,000 bushels of corn) or more. It is important to lay emphasis on the fact that these bags are specifically designed to hold grain, not chopped forage.

Although they may look similar, a grain bag must conform to more demanding standards, basically because grain’s higher specific weight and the fact that it flows freely impose a far heavier load on a bag’s sidewalls and underside than forage does.

The outer layer of a grain bag is a bright off-white color to reflect infrared radiation (i.e., heat from the sun) back into the atmosphere, while its inner layer is black in order to help maintain a lower than ambient temperature inside the bag by acting as a sunlight (i.e., visible light) barrier.
Even though polyethylene is the basic material of all grainbags, manufacturers have developed proprietary resin formulations to withstand the rigors that bags are subject to. In a top quality bag the plastic sheet should possess several attributes:

a.It must have the prescribed thickness. 

 b.It must be capable of withstanding the pressure exerted by the grain and stretch within the assigned limits without undue deformation. 

 c.It must be airtight to prevent the entrance of oxygen and any gaseous exchange with the atmosphere. 

 d.It must be impervious to water and moisture. 

 e.It must be resistant to mechanical damage and punctures from outside sources. 

 f.It must preserve its resilience and endure aging and material fatigue after many months under the sun, so it is requisite that the plastic resin be formulated with effective ultraviolet ray inhibitors. Your Flexi-Grain Storage dealer stocks grain bags that comply with all of the above and will guarantee successful completion of your grain storing and handling agenda, besides providing the peace of mind that comes from getting the job done right by using the best materials available."
