With the internationalization of the domestic market, in 2005 the total output of domestic plastic products has reached 21,985,500 tons, an increase of 12.9%, of which 442 million tons of film products, agricultural film reached 873,100 tons. Accounting for 24% of the share of the entire plastic products, an increase of 14.98% over the previous year, higher than the growth of the entire product.
At present, the international oil prices continue to rise, the plastic raw materials is also in the high market, coupled with the rising wages of domestic workers, electricity prices, making the film production costs increase, the domestic film manufacturers in a production increase, and profit decline in operating conditions The
Film manufacturers to follow up the market, increase profits, often want to produce some high value-added, special-purpose film, which on the existing domestic blown film machinery made a major requirement: whether to adapt to the current domestic market for thin film products Proposed performance requirements.
First, the direction of production
Throughout the domestic manufacturers of some presses produced blown film machine technology, basically the late 80s of last century, the early 90s introduced by foreign technology, production models are basically three co-extruded models , And occupy the dominant position, and 5 layers and more than 5 layers of co-extruded film, still the main imported equipment, only a small part of the domestic by a few of the few joint venture production, the equipment share of the country Less than 10%, only about 7%, so the majority of the existing domestic blown film manufacturers have not suited to the current market demand, the urgent need to improve technology to produce the market for blown film machinery.
(A) should be gradually extended and applied flat and tapered superimposed mold.
(B) to improve the screw to adapt to the performance of new plastic raw materials, improve the plasticizing capacity, increase production, reduce energy consumption and save energy.
(C) the production of 5 or more layers of multi-layer co-extruded blown film machinery.
(D) the production of multi-layer co-extruded heavy packaging film blown film machinery.
(5) blown film machines capable of producing environmentally friendly films (such as water-soluble films, starch films, photodegradable films, biodegradable films, etc.).
(6) to produce high-performance film blown film machinery. (Such as high-performance barrier film, high-performance nylon film, high-performance medical film and high-performance composite shrink film, etc.).
From the domestic market, in 2005 the output value of plastic machinery reached 18.873 billion yuan, an increase of 18%, extruder products amounted to 18,254 sets (sets). Extruder class of the total output value of 3.87 billion yuan. And high-grade, high-performance blown film machine (the price of 100 million yuan or more, only 100 or so) accounted for only about 1% of the total share.
Therefore, to improve product quality, increase the technological transformation of the press, improve the performance of equipment blown film manufacturers is imperative, but also these manufacturers to survive and develop the only way.
From the international market, in 2005 China's export blow molding machine 3 022 units, the total amount is 34 406 220 US dollars, imports are 365 units, the total amount is 80 837 344 US dollars, the number of net exports is 2 657 units, while the amount is Deficit of 46 431 123 dollars, which shows that China's blow molding machine exports are low-grade, low-priced products in the number of advantages, while the high-end products is almost no.
Second, the conclusion
Internationally, the Middle East, South America, the CIS and Southeast Asian countries of the press market, in recent years has gradually opened, due to institutional reasons, the economic development of different countries, the required plastic machinery is not the same, It can be said that still a virgin land to be people to develop, hope that the domestic presses manufacturing enterprises, seize the opportunity, worked hard to develop the potential of domestic and foreign presses market, so that their enterprises have greater development.
