Plastic type of beverage packaging
With the development of the national economy and the ever-increasing living standards of the people, the beverage industry in China has developed rapidly. In particular, beverage varieties have grown from single glass bottled sodas before the 1970s to today's carbonated drinks and natural beverages. The situation. The beverage packaging industry has also emerged a trend of diversification, breaking the monopoly market pattern of single glass containers in the past. Metal, plastic, paper and other materials have been applied to beverage packaging, metal cans, PET bottles, PP bottles, Tetra Pak, Combibloc, roof packs, black-and-white films and other packaging are on the market.
According to statistics, the annual output of beverages in China is basically increasing year by year, maintaining a percentage growth rate of double digits, about 10% to 20%, and the average annual total output is close to 30 million tons, which is the fastest growing rate in the food industry. One of the fast industries. At present, the domestic beverage market is dominated by fruit pulp, fruit fiber juices, low-sugar or sugar-free tea beverages, and bottled water. It is expected that the fastest-growing beverage products in 2007 will be low-sugar or non-sugar drinks. A variety of flavored tea beverages and healthy beverages such as fruits and vegetables and flowers. As the product gradually refines and subdivides the development trend, the beverage market targeting different beverage consumption groups will be more colorful.
The status of beverage packaging market
With the appearance of various types of beverages, the beverage packaging industry has also developed rapidly. After breaking the monopoly market pattern of single glass containers, metal containers, plastic containers and paper containers have emerged in succession, and beverage packaging has shown diversified development. trend. After years of market accumulation of carbonated soft drinks, pure water, and mineral water drinks, the market has become quite stable. The classic image of cans of Coca-Cola beverages cannot be easily shaken, while mineral water drinks want to have a certain share in the market, only in PET bottles. Some changes have been made in the design and capacity of the model. In recent years, 2L packaging suitable for household and catering consumption has had a market.
First, glass bottles
Glass is a long history of packaging materials, glass bottles is also our traditional beverage packaging containers. In the case of a variety of packaging materials influx into the market, glass containers still occupy an important position in the beverage packaging because it has packaging characteristics that cannot be replaced by other packaging materials, but the use of glass containers has begun to drastically decrease. The main features of glass packaging containers are: non-toxic, odorless, transparent, beautiful, good barrier properties, airtight, rich in raw materials, low cost, and can be used many times for turnover. And it has the advantages of heat resistance, pressure resistance, and cleaning resistance. It can be used for high temperature sterilization and low temperature storage. Because of its many advantages, it has become the preferred material for beverages with high requirements for packaging containers, such as fruit tea and jujube juice. However, glass packaging containers also have some disadvantages: they are mainly self-propelled, easily damaged, have high transportation costs, and have poor secondary processing properties such as printing. As a result, their usage has started to drastically decrease. Today, the shelves of large-scale supermarkets are almost invisible to glass. Drinks in containers can be seen in inexpensive places such as schools, small shops, cafeterias, and small restaurants where low-cost glass bottles of carbonated drinks, soymilk, and herbal tea can be found.
Second, metal cans
The metal cans for beverage packaging are divided into two-piece cans and three-piece cans. The two-piece cans are mainly made of aluminum alloy plates, which are mostly used for the packaging of carbonated beverages; and the three-piece cans are mainly tin plated (tinplate), and are mostly used for carbonated beverage packaging.
Metal cans as beverage packaging have the following advantages: First, they have excellent barrier properties. Not only can the gas be blocked, it can also block light, a feature that allows beverages to have a longer shelf life. Second, it has excellent mechanical properties, mainly manifested in high temperature resistance, humidity resistance, pressure resistance, pest resistance, and resistance to harmful substances. The third is not easy to break, easy to carry, to adapt to the fast-paced life of modern society. Fourth, the surface decoration is good, it can stimulate consumption and promote sales. Fifth, it can be recycled and recycled. However, metal packaging containers also have certain shortcomings, which are mainly manifested in poor chemical stability, poor alkali resistance, poor internal paint quality or poor process, which can make beverages taste bad. At present, the annual consumption of aluminum cans in China is 6 to 7 billion, raw materials are imported in large amounts, and the price is expensive. Together with factors such as environmental pollution, the country no longer approves new aluminum can production lines.
Third, plastic packaging

Together with factors such as environmental pollution, the country no longer approves new aluminum can production lines.
Third, plastic packaging
Plastic packaging in the beverage industry has attractive business opportunities. In 2002, beverage production reached 20.24 million tons, and the demand for plastic containers for soft drinks, juices, vegetables, and beverages was increasing day by day. In today's beverage market, PET holds a major position in the application of tea, carbonated beverages, fruit juices, and bottled water containers, and its prospects are promising. For example, the Watson’s “Treasure Bottleâ€, the “Him and Her-†plastic bottle, and the “Yijing†“Oriental†conical bottle, etc., make PET beverage packaging in a variety of shapes.
In the past two years, new packaging on the Chinese beverage market has gradually grown. At present, there are several types of plastics used in beverage packaging:
1, PE (polyethylene):
PE is the largest synthetic resin in the world and the largest consumer of plastic packaging materials. Polyethylene products are divided into low density, medium density and high density. Among them, high-density polyethylene (HDPE) has a high degree of crystallinity, and its hardness, airtightness, mechanical strength, and chemical resistance are good. Therefore, a large number of hollow containers such as bottles have been molded by blow molding. By using the characteristics of good heat-sealing properties of PE, containers made of various composite materials can hold various beverages such as lemon juice and fruit juice.
2, PVC (polyvinyl chloride):
PVC can be broadly divided into three categories: hard products, soft products and pasty products. The PVC bottle seamless line produced by the injection-blowing method has a uniform wall thickness and can contain gas-containing beverages such as cola and soft drinks. The PVC bottle produced by extrusion blow molding is only suitable for holding fruit juice and mineral water.
3, PP (polypropylene):
The development of polypropylene transparent packaging bottles is a hot spot for plastic packaging at home and abroad in recent years. With the successful development of the transparent modifier-nucleating agent, a 0.1% to 0.4% sorbitol xylylene (benzaldehyde) nucleating agent is added to common PP, and the highly transparent PP bottle produced can be widely used. Need heat sterilization such as juice concentrates and other beverages that require high temperature filling, its price is appropriate, pressure and temperature resistance, is the new opponent of PS, ABS, PET, PE bottles.
4, polyester (PET or PETP):
The PET bottles produced by the biaxial stretch blow molding method have good transparency, high surface gloss and a glassy appearance, and are the most suitable plastic bottles instead of glass bottles. In recent years, the production of PET bottles in China has developed rapidly and is widely used in beverages that require hot filling such as tea beverages and fruit juices, such as Pepsi 600ml, 1.25L, 2L and 2.5L PET bottles, with different volumes for individuals and families. The different needs of the general public have been well received by consumers.
From the perspective of the market share of the world’s beverage powers, the share of PET bottles exceeds 70%. According to a survey, by 2007, the European market for plastics for food and beverage packaging will increase from US$4.91 billion in 2000 to US$7.15 billion, with an average annual growth rate of 5.5%. At present, China is also in the stage of high-speed development of PET beverage packaging, and the demand for PET bottles is growing at a double-digit rate every year. The proportion of PET bottles used in domestic carbonated beverages accounted for 57.4% of the total. It can be seen that PET bottles have occupied a major share of the domestic beverage packaging market. Consumers widely believe that PET bottles have the characteristics of “large capacity, transparency, intuitive, easy to open, refrigerated, portable, sturdy, and recyclableâ€, providing a broad market prospect for their development.
Fourth, the paper container
Paper containers are used in beverage packaging and mainly refer to paper-plastic composite packaging containers made from paper composite PE film or aluminum foil, such as Tetra Pak, Kangmeibao, etc. In the shape of a roof package, sterile square brick, etc., with low cost, Lightweight, pollution-free, recyclable, and other characteristics, is a green packaging. Mainly used in short-term preservation of fresh milk, yogurt and long-term preservation of dairy beverages, tea drinks and fruit juices and other beverage packaging. However, the pressure-resistance and sealing degree of paper-plastic compound containers are not as good as those of glass bottles, metal cans and plastic containers, and they cannot be heat-sterilized. Therefore, during the preservation of the pre-formed paper boxes, the heat of the PE film will reduce its heat. Sealing performance, or due to creases, less than fiber hardening, etc., becomes uneven, resulting in difficulties in feeding the filling machine.
In April 2006, Coca-Cola selected SIG Combibloc 1.5L multi-corner aseptic carton packs, using the four large surfaces on the outside of the carton to fully display the product features, and made a special contribution to its popular Nestle NESTEA ice tea brand. Repositioning, letting it stand out on the shelves, has won consumers' favor.
The Problems and Future Trend of China's Beverage Packaging Industry
The PET bottles produced by the biaxial stretch blow molding method have good transparency, high surface gloss and a glassy appearance, and are the most suitable plastic bottles instead of glass bottles.

The Problems and Future Trend of China's Beverage Packaging Industry
I. Problems with the domestic beverage packaging industry
1, beverage packaging is facing the era of low profit
Beverage packaging is an integral part of the beverage market. In the situation where the beverage trend continues to rise, it looks promising. However, due to the price war in the beverage market, beverage companies, including internationally renowned brands, have almost equal control over packaging costs. Harsh, so that domestic beverage packaging manufacturers have almost no profit at all. At the same time, it has been squeezed by the upstream industries (raw materials), the competition in the same industry, and the downstream enterprises (customers), and the severe test of the low profit era of the packaging industry. Enterprises with weak economic strength will face greater pressure to survive. Between packaging companies It will also expand the scale of the industry through mergers and reorganizations to increase overall competitiveness. For example, the establishment of Chengdu Baobo, Lianyungang Zhongjin, Fosu Group built a factory in Sichuan, Jiangsu Shuangliang construction of Shuangliang Industrial Park, the establishment of Zijiang Industrial Park, and other examples, confirmed the advent of the era of industrial mergers and reorganization. At the same time, technology-based sales and functional packaging materials are hot spots in the industry and deserve attention from companies.
2. Beverage packaging companies are lagging behind in scale
The scale of China's beverage packaging companies is uneven, the quality of production is not effectively monitored, and there is a clear disorder in market competition, which has led to a continuous decline in the profits of the entire industry. Most of the large-scale and group-oriented enterprises are concentrated in the Pearl River Delta, Jiangsu, and Zhejiang provinces, resulting in an uneven distribution of South and North, which is uneven across the North and South. At present, domestic beverage packaging companies mainly import equipment manufactured in Japan and South Korea, and domestic machinery can only be in an auxiliary position due to the scale of investment and technical level. Most of them use SMEs as the main sales target. The production environment of the enterprise is also not optimistic. Except for one or two well-known enterprises that have GMP workshops, waste water and waste gas treatment facilities, most of the companies have inadequate production workshops. At the same time, along with the rapid development of domestic packaging companies, the upstream raw material production enterprises have been fully expanded.
The domestic beverage packaging companies’ technological processes and overall management levels lag behind the fast-growing food packaging industry. Competition is intensified, standards are raised, raw material prices are increased, and greatly reduced profits make companies exposed to management weaknesses under external pressure and how to effectively improve management levels. , To reduce internal losses and expenses, in order to increase the overall competitiveness of the market, has become an urgent need to consider the beverage packaging business operators.
Second, the future development trend of beverage packaging industry
1, the development of the beverage industry to promote the technological progress of the packaging industry
In the future beverage packaging market, the unique advantages of low consumption of raw materials, low cost, and ease of portability will determine that beverage packaging must be continuously improved in technology, so as to closely follow the pace of beverage development, using cans or glass as a packaging material for beer, Red wine, white wine, coffee, honey and carbonated beverages and other beverages, with the continuous improvement of functional films, plastic flexible packaging replacement of bottled containers and widely used is an inevitable trend. The greening of packaging materials and production processes indicates that solvent-free composites and extruded composite multi-layer co-extruded functional films will find more applications in beverage packaging.
2. Differentiation of product packaging requirements
"More and more products require more differentiated packaging" has become the trend of the beverage industry. The development of beverage packaging machinery technology will become the ultimate driving force of this trend. In the next 3 to 5 years, the beverage market will develop low-sugar or sugar-free beverages as well as natural and dairy-containing products while developing existing juices, teas, bottled drinking water, functional beverages, and carbonated beverages. And other healthy beverages are developing. The development trend of the products will further promote the development of differentiated packaging, such as PET aseptic cold filling packaging, HDPE (barrier layer middle) milk packaging, and aseptic carton packaging. The diversity of beverage product development will ultimately drive innovation in beverage packaging materials and structures.
3. Strengthen technical research and development is the basis for the sustainable development of the beverage packaging industry
After entering the year 2000, with the continuous growth of the demand in the Chinese beverage market, domestic beverage equipment manufacturers will further strengthen their own equipment technology research and development efforts, and began to engage in the development and application of high-end beverage packaging technology. At present, domestic equipment suppliers have made great progress in this regard, and have a strong competitive strength in terms of price and after-sales service. Some domestic beverage equipment manufacturers such as Guangzhou Tech-Long, Lehui Enterprises, GuangGuang, NanGuang, XinMeiXing, etc. have demonstrated their potential and advantages in offering low-to-medium-speed (18 000 BPH to 24 000 BPH) beverage packaging lines. Its main performance is in very competitive overall line prices, good local technical support and after-sales service, relatively low equipment maintenance and spare parts prices. It can be said that it is this demand of beverage companies that has promoted the common development and progress of beverage companies and beverage packaging companies.
Beverage packaging will develop into a distinctive packaging industry with green environmental protection, profit reduction, merger and reorganization, brand sales, and high quality and high energy. How to better develop the packaging industry based on the purpose of “safety, health, and environmental protection†is an issue that companies need to consider urgently. Enterprises that deviate from the mainstream will eventually be eliminated by a gradual sound market competition system.
