2. Plastic packaging industry Plastics, with its unique excellent physical and chemical properties, occupy an important position in the packaging materials. Among the four modern packaging materials, namely paper, plastic, metal, and glass, plastic packaging materials have already ranked second. The province's plastic packaging industry has developed rapidly and its product range is complete. About 30% of packaging materials, some products have also become the bulk of exports of foreign exchange, such as plastic woven bags, is China's traditional export products. Zhuhai Zhonghua Plastic Bag Factory produces plastic bags for various kinds of goods sales and packaging, with an annual output of up to 70,000 tons, all of which are exported abroad. The ethylene production bases in Guangzhou, Maoming ethylene, and Nanhai Petrochemical, which will be launched, have laid a solid foundation for the development of the plastic packaging industry. Plastic packaging mainly includes plastic packaging films, plastic hollow containers (barrels, bottles, cans, etc.), plastic hoses, plastic bags (film bags and woven bags), plastic turnover boxes, trays, foam cushion packaging, insulation, fresh-keeping packaging containers, etc. . Plastic packaging industry adjustment ideas:
A. Strengthening New Product Development Our province has taken the lead in introducing and producing BOPP film and BOPET, CPP, OPP, PA, PVDC films in China. However, in recent years, the domestic BOPP film production capacity has exceeded the market demand, so our province has to develop other New, more excellent packaging substrate. Such as: for high temperature, low temperature, cooking, etc., multi-layer co-extruded high barrier performance films and sheets on food packaging; multi-layer co-extruded stretch-wound film for better wrapping performance; Hot-filled, high-temperature resistant PET beverage bottles and PET beer bottles; Synthetic papers for goods labels and bags; Water-soluble films, metallocene films, etc.
B. Urgently to introduce and develop new technologies and high strength;
New Molding Technology, Shaped Hollow, Nano-Plastic Technology, Co-Extrusion Technology and Container Thin Technology; (Degradable Plastic Technology) Applications of Microelectronics, Plasma, Ultrasound, and Infrared Technology in Films and Containers; Masterbatches; Plastics Packaging waste recycling technology and so on.
C. The development of plastic packaging and the strengthening of recycling The simultaneous increase in the share of plastics in various types of packaging has gradually increased. What follows is the recycling of plastic packaging waste. This is an important part of ensuring the sustainable development of plastic packaging. The recycling of plastic waste is a difficult and nuanced work. It is a systematic project that must be adopted. The government has legislated and managed effectively, for example, the sorting of domestic waste that Guangzhou is preparing to implement has laid a good foundation for the recycling of waste plastics. In addition, efforts should be made to increase publicity and education so as to raise the national environmental awareness. The government shall specify the recycling targets and recycling ratios for disposable plastic packaging products, and impose mandatory requirements on production and sellers.
3. Metal Containers Industrial metal containers mainly include steel drums, two-piece aluminum cans, tinned iron cans (three tin cans), metal bottle caps, can lids, and aluminum foil containers. During the initial period of reform and opening up, beer, beverages, candy, biscuits, and other foods produced in Guangdong Province were known as “Pearl River Water, Guangdong Food†and were once popular in the country. The production of metal containers matching them was also very brilliant. Now, there are 7 aluminum alloy cans production plants in our province, about 100 printed and iron canning plants, about 20 metal caps and cans production plants, 5 metal spray cans production plants, and 200 litre steel drum production plants. Home, about 20 other drum production plants. The technical equipment of the metal container industry in our province is relatively advanced. For example, in the aluminum alloy two-piece can industry, an advanced production line with a can body production capacity of 1600 cans/year and a production line of 2000 cans/can lid are introduced. In the printing and canning industry, 600 cans per minute high-speed automatic resistance welding can production line and seven-color computer printing iron production line, in addition to metal spray cans, crown caps, steel barrels, etc., have advanced automatic production lines. The scale of enterprises in the metal container industry in our province is also growing. There are more than a dozen companies with production value exceeding 100 million yuan.
As the market competition becomes more intense, especially with the loss of advantages in beverages and foods in Guangdong Province, the metal container industry in our province is also experiencing more and more difficulties. For this reason, the adjustment ideas for this industry are:
A. Consolidate and increase the current production capacity of metal containers The current production capacity of metal containers in our province is excessive, so it is not appropriate to launch new production lines in the near future to avoid further deterioration of the situation. Due to the large volume and light weight of metal containers, the sales radius is limited. Under normal circumstances, long-distance transportation is not appropriate. The balance of production and sales of metal containers is solved. The first is to work together with supporting industries (especially the food and beverage industry). Develop marketable products to expand the market share of canned foods. For example, aluminum alloy two-piece cans consume an average of 400 cans per person per year in the United States. They are mainly used for the loading of carbonated beverages such as beer and cola, while China’s current average is only about 4 cans.
B. Development of marketable new products and new technology Tinplate two-piece cans, the cost is lower than the aluminum alloy two-piece cans, but the strength is better, now only one company in Shanghai produces, the annual output is 800 million cans. In addition, in order to expand the market share of tinplate three-piece cans, it is necessary to develop and introduce a full-pot make-up coating technology to improve the corrosion resistance of the three-piece cans. The development of new (eg, salted) canned foods and beverages, such as spray cans, currently produces only two sizes, φ65mm and φ52mm, which have not yet been serialized. This has limited the development of spray products to some extent. In fact, for example, in the pharmaceutical and food industries, spray packaging has certain development prospects, but it is necessary to develop a series of applicable specifications.
C. Development of raw material production base After years of development, the production capacity of tinplate (tin-plated steel sheet) in our province and in China has met the needs. However, as the province with the largest concentration of aluminum alloy two-piece cans in China, the province should consider the preparation of a tank aluminum alloy plate production enterprise (there is no such enterprise in China at present), which can not only solve the problem of raw materials for aluminum alloy two-piece can manufacturing enterprises. Problems, but also through the recycling of two-piece cans and scrap, to solve environmental problems and further reduce the canning cost. Aluminum foil is an important substrate for packaging. It is mainly used for the packaging of tobacco, composite flexible packaging, candy, daily chemicals, pharmaceuticals and other products. At present, the varieties and quality of aluminum foil products in China are difficult to meet the needs of the domestic market, and a large amount of imports are still needed each year. Therefore, our province should also consider the preparation of a high-quality aluminum foil production enterprise to meet various needs.
4. Packaging and Printing Industry Packaging printing has the fastest development in the packaging industry. There are more than 6,000 enterprises engaged in packaging and printing in Guangdong, of which about 30 have sales of over 100 million. The revised “Management Regulations of the Printing Industry†allows foreigners to set up wholly-owned packaging and printing companies, which is expected to further promote the development of this industry. The idea of ​​packaging and printing industry adjustment is:
A. Strengthen management and standardize the market Due to the special nature of the packaging and printing industry, it is necessary to strengthen the management of the packaging and printing industry so as to avoid the occurrence of illegal activities such as fraud. To strengthen management, the first is through the government, and more importantly through industry organizations to help companies raise awareness and strengthen self-discipline and mutual supervision. In addition, newly established enterprises must appropriately improve market access conditions and resolutely crack down on packaging and printing companies that are illegally operating underground.
B. Enhancing the position of flexo printing in packaging printing Flexo printing belongs to the traditional category of letterpress printing. Since the 1980s, due to the use of a large number of modern technologies in flexo printing, flexographic printing has been greatly improved. In Europe and the United States and other developed countries, the proportion of flexographic printing in packaging and printing has exceeded 50%, while the flexographic printing in China is still in its infancy, accounting for less than 2%. Flexible printing equipment usually uses reel-type printing materials, which can be completed from two-sided or single-side printing to finishing, laminating, bronzing, die-cutting, discharging, winding or slitting, etc. The printing cycle reduces costs. The range of flexo printing and gravure printing is comparable, but the investment is only about 30% of gravure printing. Flexographic printing can also use water-based ink, which is conducive to environmental protection. In recent years, China has made great breakthroughs in the development of all kinds of technical equipment such as flexo printing machines, anilox rollers, inks, and printing plates. The time for the promotion and application of flexo printing in packaging and printing has gradually matured. The overall goal is to increase the proportion of flexo printing in packaging printing to 12%-15% by 2010. Therefore, first of all, we must do a good job in the flexo printing industry's process operations and management training. Followed by a good grasp of supporting equipment (flexo printing machines, plate making machines, etc.) and supporting materials (plate, anilox roller, ink, varnishes, etc.) products to improve work.
C. Accelerating the development of high-tech lithographic printing technology At present, plain printing is still the main force of packaging and printing. More than 50% of the packaging and printing products use plain printing technology. In recent years, the lithography technology has been continuously incorporated into high technologies such as optical, chemical and electronic computer systems, reflecting the level of contemporary high technology. The printing technology is still developing rapidly and we must keep up. Mainly include: direct plate making technology; direct printing technology; no horizontal printing technology; FM network technology.
D. Steady development of gravure gravure Printing has the advantages of high speed, wide width, low consumption, short downtime, and best results on various substrates. Due to the good quality of gravure printing and the completeness of supporting equipment, China has more experience in use. Therefore, gravure has formed a scale in packaging printing. The proportion of gravure printing in packaging printing has exceeded 10%, and it should still develop steadily in the future. By 2010, this proportion should rise to 12%-15%.
E. Broadening the market scope of special printing technologies The special printing used in the field of packaging and printing is screen printing. The screen printing screen is soft and flexible, and can be printed on various materials and different shapes of substrates. The screen printing ink has a thick layer and a strong glue effect. Silk screen printing and electrolysis processes, bronzing processes, calcining processes, plastic molding processes, etc., can produce different types, rich and colorful artwork, and therefore are more and more popular for packaging users. Silkscreen now accounts for less than 2% of packaging printing. Hope to increase to 7%-8% by 2010. Other special printing technologies, such as the application of laser holographic printing technology in packaging and decorating materials, and the application of transfer printing technology on flat curved surface printing materials, have been developed and improved in breadth and depth.
5. Glass Container Industry Glass container production industry mainly provides products for beer, liquor, beverages, food, medicine, chemicals, pesticides and other industries. Since the reform and opening up, the production of glass containers in our province has introduced and digested and absorbed foreign advanced technology and equipment, which has greatly improved the level of technical equipment in the entire industry, and greatly increased the variety and variety of products. Taking beer bottles as an example, the single varieties that have remained unchanged in the past few decades have now developed green, brown, and white 640 ml, 500 ml, 355 ml, 296 ml beer bottles that have been developed and put into the market. Our glass container industry now has a number of large-scale backbone enterprises such as Guangdong Aolian Glass Company. Glass containers have significant advantages such as good barrier properties, corrosion resistance, and transparency and intuition. However, they also have disadvantages such as heavy weight, difficulty in carrying, and being easily damaged. In particular, the occurrence of personal injury due to blasting of beer bottles occurs from time to time. Plastic hollow containers have captured an increasing share of the glass container market. In the face of competition, the adjustment ideas of the glass container industry are:
A. Deepening technological transformation and enhancing competitiveness Even though the weight of beer bottles has been reduced by 5%-15%, the weight ratio is still larger than that of hollow plastic containers. To this end, advanced production techniques and processes should be further introduced to produce glass containers that are lighter and have higher strength.
B. Upgrade the grade of glass containers In the developed countries, glass containers belong to high-grade packaging containers. However, the existing glass containers in our province are still in short supply, especially high-grade special-shaped bottles and frosted bottles for cosmetics and high-grade wines. And deep processing products such as printing technology are still lacking and need to be developed to meet market needs.
Third, catch up with the development trend of the world packaging industry With the rapid development of China's economy, the level of consumption is increasing, and consumption patterns are gradually in line with international standards. In terms of packaging, we should pay close attention to the following trends and catch up with our actual situation.
1. The packaging industry rapidly responds to changes in consumer demand and production tends to diversify. The development of new products is fast and short.
2. The packaging industry is committed to providing consumers with more convenient packaging. For example
