The former is suitable for transporting artificial gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. Compared with steel pipe, the construction technology is simple and has certain flexibility. What's more, it doesn't need anti-corrosion treatment, which will save a lot of working procedures. The disadvantage is that the equipment is not as good as the steel pipe. Special attention should be paid to the safe distance of thermal heating during construction, and it should not be exposed to the air and sunlight, and it is sensitive to chemicals to prevent the leakage of sewage pipeline from causing damage. Edible packaging film is a kind of film with porous network structure, which is made of natural edible substances (such as polysaccharides, proteins, etc.) through the interaction between different molecules. For example, chitosan edible packaging film, corn protein packaging film, modified cellulose edible packaging film and composite edible packaging film, etc., edible film can be used in the internal packaging of various ready to eat food, which has a huge market in the food industry.
