Material and Marking Requirements for Fertilizer Packaging Bags

1. Fertilizer packaging materials: In the fertilizer standards, detailed regulations are made on the packaging technical requirements of fertilizers, the quality of packaging materials, the test methods of packaging, inspection rules and the markings of packaging. The standard specifies the packaging materials of solid fertilizers: the outer bag is a plastic woven bag, and the inner bag is a high-density or low-density or modified polyethylene film bag (only the ammonium bicarbonate inner bag can use a polyethylene film bag), or a two-in-one bag. A composite bag, but the ammonium bicarbonate is not packaged in a composite bag. The standard also points out that it is not allowed to use plastic films produced from recycled materials as inner weighing bags in multi-layer bags. All packaging materials that do not meet the above requirements and are of poor quality should be noted that they may be fake and inferior products.

2. Marks on fertilizer packaging bags: The standards for fertilizers at all levels clearly stipulate that the product name, nutrient content or grade, net weight, production plant name and address, standard label and production license number must be printed on the fertilizer packaging. If the above main signs are missing or incomplete, it should be noted that they may be counterfeit and shoddy products.

In addition, pay attention to whether the fertilizer packaging is in good condition. If you find split marks or heavy seams, pay attention to those who use old packaging to fill fake and inferior fertilizers.
