Inquiry (采购产品): Health and Pharmaceutical We need to package custom herbal formulas in heat seal teabags, approximate size of 125mmx140mm. Is your product#XHTB18G food approved and safe for boiling 1-2 hours, because customers will drink the tea after boiling. We are looking for either paper in rolls or in premade bags, closed on 3 sides and open on one side so we can put the herbs in, then seal. We also need to purchase a manua/ simple heat sealing equipment.
