These fertilizer packaging drums use HDPE. We add 2% carbon black or UV masterbatch. The drum can handle 2 years of outdoor sun exposure. The neck has a vent pipe. When the internal pressure reaches 0.02 MPa, the valve opens automatically. The drum will not deform. Each batch goes through a stack test with six layers for 72 hours. Workers check 100% of the drums.
Liquid fertilizers can ferment and produce gas. Regular drums will bulge. Our drums have a one-way vent valve. The gas escapes. A US liquid fertilizer company made fermented fertilizer. Their old drums bulged. We gave them drums with a vent valve. They tested for three months. The drums did not deform. Their first order was 100,000 pieces. Now they reorder every quarter. MOQ is 10,000 pieces. Sample takes 7 to 10 days. We support FOB. If goods get damaged, we send new ones for free. Our after-sales team follows up.
