Feeding mixed into plastic bags, plastic bags are generally 17 cm wide, 35 cm long, high temperature resistance of high-quality low-pressure polyethylene or polypropylene folded bag, the bag loaded with the same density of the material to maintain a smooth surface without bumps and bumps, the surface of the material and the bag tightly pasted, the mouth of the bag with a plastic set of rings or cotton plugs with a thin rope tightly, each bag can be loaded with dry material 0.35 kg or so, about 0.75 kilograms of wet weight.
