Q:What are the common materials of tea packing bags?

PE bag (plastic bag)Polyethylene bags, or PE bags, are widely used packaging materials at present. There are two kinds of low density PE bags and high-density PE bags. The low density PE bags are breathable and breathable, while the high-density PE bags are smaller.The advantages of PE bag are economical, cheap and damp proof. Its disadvantages are light transmission and poor air resistance. It can not be used in tea packaging individually. The best can add a layer of light resistance and low permeability of the outside packaging using polyethylene bags, such as synthetic paper cans, cans and other PE bag permeability is bigger, also difficult to solve the problem of oxygen in the packaging bag, and is not the ideal packaging material.
