4 ppo plastic
 
 
concept
 
PPO plastic, the Chinese name is polyphenyl ether. It has the advantages of large rigidity, high heat resistance, flame resistance, high strength and excellent electrical properties. In addition, polyether also has wear - resistant, non - toxic, anti - pollution and other advantages. PPO's dielectric constant and dielectric loss are among the smallest varieties in engineering plastics, which are almost impervious to temperature and humidity and can be used in low, medium and high frequency electric fields. PPO load deformation temperature can reach 190 ℃ above, brittle temperature to - 170 ℃.
 
Pure PPO material has the disadvantages of poor melt fluidity and high price. The products sold in the market are all improved products with excellent comprehensive performance.
 
 
application
 
 
PPO plastic is widely used in: electronic electric: can meet under the condition of damp, load, high temperature with excellent electrical insulation, preparation of television product machine tuning, coil core, microwave insulation parts, shielding cover, high frequency electric road plate, all kinds of high voltage electronic components, such as TV sets, computers, fax machines, photocopiers shell.
 
Automobile industry: suitable for instrument panel, window frame, shock absorber, pump filter, etc.
 
Mechanical industry: used for gear, bearing, pump impeller, blower impeller, etc.
 
Chemical industry: for the production of pipelines, valves, filters and submersible pumps and other corrosion resistant parts.
 
 
5 main tasks
 
 
The main task of China's plastic packaging industry is to develop new plastic molding equipment, gradually narrow the gap with foreign manufacturers, and compete with it in the market. The plastic packaging enterprise must change the enterprise development way, the enterprise must stand on the new starting point to examine and solve the above contradiction and the question, takes the scientific development view as the guidance, the transformation development idea, the enhancement independent innovation, the enhancement market consciousness, promotes the enterprise development effectively.
 
Europe and the United States is the world's most developed plastic packaging industry countries, attaches great importance to the development and development of advanced packaging machinery. According to the international mold and metal plastic industry suppliers association secretary general luo baihui introduction, Europe and the United States of various types of packaging machinery, advanced equipment, but in order to be able to adapt to the international market competition, they are still developing and developing more advanced plastic packaging machinery and equipment.
 
Under such circumstances, China's packaging machinery industry enterprises should adhere to the "go out" development strategy, and actively expand foreign markets. ROM hundred hui pointed out that the domestic packaging machinery industry enterprises should adopt offensive operations, actively participate in the international industry and cross-industry cooperation between enterprises, mergers and acquisitions, through overseas investment and acquisition of foreign enterprises, for its advanced technology digestion, absorption, and to realize the localization as soon as possible, raise the international status of the packaging machinery industry in China.
 
The booming processing service industry has stimulated the strong demand for packaging machinery, which provides good business opportunities for Chinese packaging machinery suppliers. In the competition with European and American enterprises, China's packaging machinery enterprises have begun to appear. China is the world's largest plastic production base, but in the plastic packaging industry upstream of the plastic packaging machinery industry, is basically the monopoly of imported equipment.
 
 
 
6. Industrial development
 
 
China is a big country of packaging manufacturing and consumption in the world. The proportion of plastic packaging in the total output value of the packaging industry has exceeded 30%, becoming a new force in the packaging industry and playing an irreplaceable role in various fields of food, beverage, daily necessities and industrial and agricultural production. The plastic packaging industry's packaging products, packaging materials steady growth, new packaging materials, new processes, new technologies, new products continue to emerge.
 
From January to December 2006, China's plastic packaging and container manufacturing industries realized a cumulative industrial output value of 57,615,577,000 yuan, an increase of 22.83% over the same period last year. Realized the cumulative product sales revenue of 55,288,976,000 yuan, an increase of 23.15% over the same period of last year, realized the total cumulative profit of 3,124,783,000 yuan, an increase of 1.39% over the same period of last year.
 
From January to December 2007, China's plastic packaging and container manufacturing industries achieved a cumulative industrial output value of 73,093,169,000 yuan, an increase of 26.72% over the same period last year.
 
From January to October 2008, China's plastic packaging and container manufacturing industries achieved a cumulative industrial output value of 73,367,215,000 yuan, an increase of 21.48% over the same period last year.
 
The use of plastics in both rigid containers and flexible packaging will increase. In the case of rigid containers, such as plastic trays and plastic drums, the long-term cost is lower than that of fiberboard drums due to their reusable nature. Plastic upright bags are also intended to replace cardboard boxes as containers for dry goods such as pre-made cereals and sauces. In addition, due to the characteristics of light weight and collision resistance, plastic bottles are increasingly used in the packaging of fruit juice and fruit drinks. In flexible packaging, the small bags and films found in plastic products will continue to be useful in the field of fast food and retail.
 
Plastic packaging upstream related machinery
 
Blow molding machine, injection molding machine, vacuum molding machine, pressure molding machine, foaming machine, plastic calender, plastic molding machine, plastic extruder, auxiliary machine
 
Plastic packaging downstream main users
 
Plastic packaging has been widely used in electronics, food, beverage, wine, tea, cigarettes, medicine, health care products, cosmetics, small household appliances, clothing, toys, sporting goods and other industries and product packaging supporting industries, is an indispensable industry.
 
 
7 arrested development
 
 
The plastic packaging market is gradually on the right track, and the development prospect is promising. As the largest piece of plastic application field, its development speed is growing day by day, which has already exceeded cardboard and other packaging materials such as metal. However, the future of the plastic packaging market is still limited by some factors, one of the biggest constraints is the problem of funds.
 
"It is difficult for plastic packaging enterprises to do, and the phenomenon of payment delay in the industry is very serious. We have not received the payment for goods last year. It's planned to expand this year, but it's very difficult to get financing from the Banks. Shenzhen simeida packaging products co., LTD., hereinafter referred to as "simeida" general manager xiao xuefeng told reporters. According to the introduction, simeda is a large professional production of all kinds of environmental protection thermal shrink film, shrink bag, PVC, PET, OPS color printing shrink label film, OPP, PE plastic bag, at the same time operating a variety of protective film, stretch film and its packaging design and processing manufacturers, the early development and production of such products in shenzhen. Shenzhen plastic packaging enterprises mainly in the face of European and American markets, with the spread of the debt crisis, gradually reduce plastic packaging companies in Europe and America market order, and even the phenomenon of zero order, along with austerity, high labor costs, raw material prices, electricity and energy saving and a series of constraints, plastic packaging enterprise's survival and development difficult.
 
"Simeida's products are sold to the pearl river delta, the mainland, Europe, the us and southeast Asia. In previous years, we received some export orders every two months on average, but this year, so far, we have not received any." Xiao xuefeng said that the reduction of export orders, so that many plastic packaging enterprises have turned to the mainland market, in order to win more customers, the competition between enterprises to play a price war, low-end products line, low prices. There are fewer export orders and less demand. The rent of the factory has gone up, the wages of the workers have gone up, and the price of raw materials has gone up. The market is in a slump. In this industry, going low-end simply doesn't work. Xiao xuefeng said: "the low-end product line of the enterprise, can only play the idea of raw materials, raw materials quality is not good, the quality of the products produced will certainly be poor, the enterprise reputation will be damaged, or even by customers in accordance with the contract deduction or fine. Last year, more than a dozen plastic packaging companies in shenzhen closed down, and many sold their multimillion-dollar equipment for hundreds of thousands or less.
 
"At present, the domestic market is also relatively mature, we have cooperation with byd, Canon, kasich milk and other companies. We are not worried about orders, but capital is still a big problem restricting the development of enterprises. In this industry chain, when we receive orders from customers, we need to pay for raw materials, and only after we deliver the goods to customers, will the customers remit the money to our company's account. 'normally, the contract says one month, but it's good to receive payment within three months,' Mr. Xiao said. Some customers delayed for half a year, a longer delay of a year did not clear the payment. Dragging money is common phenomenon, a lot of are old client again, cannot because did not fulfil contract agreement and fall out. Enterprises have short-term financing needs, lack of funds, the general will borrow money from friends.
 
Xiao xuefeng told reporters: "in this industry chain, product manufacturers caught in the middle, to buy raw materials, must come up with cash. However, the customer who placed the order would not remit the payment to the product manufacturer in time. Instead, the payment was often delayed. Based on this phenomenon of arrears, enterprises lack the capital for reinvestment. "We often receive orders of tens of millions of yuan, such as the byd company's order this year, but the enterprise lacks working capital and financing is difficult, so we have to give up. 'we can only appeal to customers to shorten the settlement time,' he said. 'many small businesses can't afford to be in arrears for a long time.'
 
Xiao xuefeng admitted that he was optimistic about the development prospects of the industry, the plastic packaging film mainly for the consumer industry, the purchase of good quality raw materials, multi-machine operation, the company's sustainable development space is still very large. The company turned to the bank for financing and finally gave up because the bank required collateral, the loan procedures were complicated and the loan time was slow.
 
Xiao xuefeng said that Banks, as enterprises, to profit but also to avoid risk, prudent lending is understandable. However, for smes in the growth stage, Banks should lower the threshold of loans and set up loan conditions according to the needs of smes. "Every enterprise needs a strong capital flow to become bigger and stronger. It needs millions or more of capital to take orders from a big customer. Without the support of bank funds, a big order may drag down an enterprise."
 
As an industry with good development prospects, the plastic packaging market should be paid attention to. Enterprises and customers to do a good job of communication, non-default, in addition, for the plastic packaging market, the bank should lower the threshold, timely for its financial support, so that the plastic packaging market more enough to have a broader prospect for development.
