加拿大采购需求：大麻包装咖啡袋、蒸煮吸嘴袋、食品包装袋、冷冻食品包装袋、带侧边折边的牛皮纸袋、宠物食品袋制造商

I'm in search of Stand Up Pouches suitable for packaging larger quantities of Cannabis Flower for export purposes. Our company, located in BC, Canada, is focused on the legal cannabis industry and currently struggles to find a cost-effective solution for packaging 3KG of flower. The existing bags we use are on the pricier side, measuring approximately 20 inches wide by 29 inches high, with a thickness of 4.0 MIL and no bottom gusset. I'm interested in receiving quotes for similar or appropriately sized bags you may offer. If you do have standard sizes or the option for custom ones, I'd love to hear about that too. My preference would be for matte black bags with a gusset, and no graphics needed. Additionally, if you provide samples, that would be appreciated to assess your product quality. Looking forward to your response!
