Zhenjiang Shanghao Packaging Co., Ltd. specializes in manufacturing paper CD sleeves and all kinds of envelopes. We are also one of the largest professional manufacturers of envelope machinery in China. They are the major machines to produce standard envelopes that the Ministry of Post and Telecommunication generalizes as an emphasis. Especially, the successful development of the PTF series fully automatic integrated machine has settled the leading position of our company in the domestic envelope machinery industry. Our company is also one of the largest professional manufacturers of ZYB series oil and oil-free pumps in the country. The ZYBW100 and ZYBW140 oil-free pumps are ideal substitutes for the imported pumps for printing and packaging enterprises. They have become the associated partners of printing and packaging machinery. For our further development, we will build a new modern garden type plant with an area of over 30,000 square meters step by step to enlarge the production scale. At the same time, we will introduce more advanced digital control machines and management personnel to increase the manufacture level and management level of our company. We will make efforts to improve the sales and after sales network, and work hard to create a first-class brand of envelope machines and air pumps. We welcome fellow traders at home and abroad to negotiate with us about the cooperation.
