See the specification chart—there are six grades available: 10–20 mesh, 20–40 mesh, 40–60 mesh, 60–80 mesh, 80–100 mesh, and 100–200 mesh.
3) Product Specifications (Distillation Purification and Sublimation Purification Processes)
Two specifications: distilled flakes and sublimed superfines;
4) Product Packaging
Packaged in drums: Each paper drum is lined with a double-layer, food-grade PE plastic bag, securely sealed at the opening. The drum lid is tightly closed for storage, and the exterior of the drum is wrapped in another PE plastic bag, which is also tied tightly at the top. The drums come in two shapes—round or square—and each drum (or box) contains a net weight of 25 kg.
Paper drum dimensions: Round drum: φ36 × 45; square drum: 36 (length) × 36 (width) × 34 (height). Bagged packaging: 25 kg per bag—packed in either PP plastic woven bags or kraft paper-plastic bags, with a double-layer lining of food-grade PE plastic bags inside. 650 kg per ton
Packed in bags: outer bag made of plastic woven fabric, with an inner PE film bag. Additionally, we can package individually according to the customer’s specified weight requirements.
