Thread Content

Current development status and future prospects of the BOPP (biaxially oriented polypropylene) film industry. BOPP film is a very important type of flexible packaging material that is widely used; it features high tensile strength, impact resistance, rigidity, toughness, and good transparency. B0PP films have a low surface energy, and corona treatment is required before coating or printing. However, after corona treatment, the B0PP film exhibits good printability, allowing for color printing to achieve an elegant appearance, which is why it is commonly used as the surface layer material in laminated films. BOPP film also has drawbacks, such as the tendency to accumulate static electricity and the lack of heat-sealability. On high-speed production lines, BOPP films tend to generate static electricity, so an antistatic device needs to be installed. To obtain heat-sealable BOPP film, the surface of the BOPP film can be corona-treated followed by the coating of a heat-sealable resin adhesive such as PVDC latex or EVA latex; solvent-based adhesives can also be used. Heat-sealable BOPP film can be produced through extrusion coating or by extrusion lamination methods. This film is widely used in the packaging of bread, clothing, shoes, and socks, as well as in the cover packaging of cigarettes and books. The initiation tear strength of B0PP film increases after stretching, but its secondary tear strength is very low; therefore, no cuts should be left on either end face of the BOPP film, otherwise it is prone to tearing during printing and lamination. Production of BOPP film BOPP film can be produced using the tubular film method or the flat film method. The properties of BOPP films obtained through different processing methods also vary. BOPP films produced by the flat film process have higher strength than those made by the tubular film process, as they feature a high stretch ratio (up to 8–10), and they also exhibit better uniformity in film thickness. To achieve better overall performance, a multi-layer composite method is typically used in the production process. BOPP can be compounded with a variety of different materials to meet specific application requirements. For example, BOPP can be compounded with LDPE (CPP), PE, PT, PO, PVA, etc. to achieve high gas and moisture barrier properties, as well as transparency, resistance to high and low temperatures, steam cooking, and oils. Different composite films can be used for packaging oily foods, delicacies, dried foods, marinated foods, various steamed dishes, monosodium glutamate, pancakes, rice cakes, and more. Uses of BOPP film: It is used as a film for printing and lamination. In the field of printing, BOPP film is primarily used in gravure printing, accounting for about 22% of all printing methods; offset printing accounts for 42%, letterpress printing for 20%, flexographic printing for 8%, and other methods for another 8%. According to incomplete statistics, China has introduced nearly 600 new production lines from countries such as Japan, Switzerland, Germany, France, Italy, South Korea, Australia, and Taiwan Province of China. In addition, there are over 4,000 domestic gravure printing production lines. The annual consumption of BOPP film amounts to around 900,000 tons, accounting for 70% of the BOPP market. This consumption is concentrated in the East China region. The companies that use the most BOPP film include Shanghai Zijiang, Dalian Dafu, Zhongshan Dafu, and Shanghai FLE*BLE Packaging. Based on performance, they are divided into three types: general-purpose cigarette packaging film, heat-shrinkable cigarette packaging film, and high-speed cigarette packaging film. General-purpose cigarette packaging film: It is suitable for various types of cigarette packaging machines; its adaptability allows it to cope with minor adjustments in the packaging machines without causing any problems. Its main advantages include good adaptability to packaging machines, excellent smoothness, a wide heat-sealing range, high rigidity, antistatic properties, and superior folding quality. Thermoshrinkable cigarette packaging film: Its main features include an excellent ability to fit tightly around the cigarettes, overcoming the problem of loosening and wrinkling associated with hard-box packaging films, as well as low-temperature thermoshrinkability and fast packaging capabilities. High-speed cigarette packaging film: Particularly suitable for high-speed cigarette packaging machines, it ensures the production of high-quality products at fast speeds. The tobacco industry is a major customer of B0PP films. According to data provided by China Tobacco Online, after the mergers and reorganizations in China’s tobacco industry, the annual production capacity is 66.75 million cases; based on this, the annual demand for tobacco packaging films in China is estimated to be 10 million units. 680,000 tons. If the usage in unplanned and underground cigarette factories is included, the nationwide consumption of cigarette packaging film in 2005 was likely around 130,000 tons, accounting for 10% of the average total for B0PP. These are theoretical figures; high-end cigarettes still rely mainly on imported packaging film, and only in recent years has this usage started to decline year by year. As cigarette label designs become increasingly complex and sophisticated, along with the increase in the speed of cigarette packaging machinery and the long-distance transportation of cigarettes, consumers have higher aesthetic expectations for cigarette packaging, and cigarette manufacturers have greater demands on BOPP film. Regarding capacitor films, statistics show that there are over 20 companies in the country that produce such films. The vast majority of them use specialized equipment designed for manufacturing BOPP capacitor films, while some use equipment originally intended for producing BOPP packaging and printing films, which has been modified for this purpose. The annual production capacity is 80,000 tons; however, as a portion of it has not yet been put into use, the actual output is around 60,000 tons, with market demand being roughly balanced. Once the designed capacity is reached, there will be a surplus, and profits will further decline; therefore, the situation for capacitor film manufacturers is not optimistic. Development trends of BOPP film: Based on the current situation of the BOPP industry, the main development trends at present are as follows: moving towards larger scale and greater integration, as this is the only way to reduce costs, enhance product competitiveness, and leverage the resources of large enterprises for technological innovation. There are now 91 such companies, and it won’t be long before some of the smaller factories are acquired by larger, more powerful enterprises. Currently, companies such as Jiangsu Shuangliang, Foshan Dongfang, Guangdong Hongming, Anhui Guofeng, Dalian Sanrong, Jiangsu Zhongda, Zhejiang Dadesong, and Baosu Group have production capacities ranging from 60,000 to 100,000 tons per year. They are highly specialized, innovative in technology development, and capable of competing with foreign counterparts. Production lines are evolving toward higher speed, greater width, and increased productivity: In recent years, 67 production lines with a production capacity of over 20,000 tons have been introduced. Although these lines account for only 37.22% of the total number of production lines, they generate 70.19% of the total output. Anhui Guofeng has introduced a production line that is 10 meters wide and operates at a speed of 450 m/min; it is said to be the widest production line in the world at present. Each manufacturer makes use of its strengths to offset its weaknesses and seeks development in order to survive. Those with high-capacity production lines (over 20,000 tons per year) generally use these lines to produce products of a single variety, while those with smaller capacity lines take advantage of their flexibility in changing specifications to manufacture smaller-scale products (specialized films) that the high-capacity lines are unwilling to produce. In this way, each party leverages its own advantages to coexist and thrive together. The pace of corporate restructuring is accelerating: it has been proven that private and foreign-owned enterprises perform better than state-owned enterprises, and state-owned enterprises will undergo restructuring one after another. Strive to survive. Increase investment in technological innovation: Many domestic companies recruit top talent, boost efforts in developing new products, and offer generous rewards to those who contribute to such product development, thereby effectively promoting the growth of these companies. A few years ago, the production of BOPP film yielded high profits, which spurred its rapid development. In particular, two waves of large-scale investment took place between 1996–1997 and 2001–2004, resulting in the number of BOPP film manufacturers in China rising to 109, with 180 production lines in operation (as of May 2005). These manufacturers are spread across more than 20 provinces, municipalities, and autonomous regions. The manufacturers of BOPP film in mainland China are unevenly distributed; merely the provinces of Zhejiang, Jiangsu, and Guangdong account for 67.20% of China’s BOPP production. Among them, Zhejiang accounted for 54,200 tons, representing 22.19%; Jiangsu accounted for 56,100 tons, accounting for 22.96%; Guangdong accounted for 53,860 tons, representing 22.05%. The remaining 17 provinces and municipalities accounted for only 32.80%, while 12 provinces, municipalities, and autonomous regions had no data recorded. B0PP film is an important product in the packaging industry. Thanks to its advantages such as light weight, transparency, non-toxicity, moisture resistance, low air permeability, and high mechanical strength, it is widely used in industries such as food, pharmaceuticals, light manufacturing, and tobacco. The challenges in the development of BOPP: There is a severe imbalance between supply and demand for BOPP film in the domestic market. By the end of 2004, China’s BOPP film production capacity was around 1.93 million tons, with output at approximately 1.3 million tons. Production capacity increased by about 660,000 tons compared to 2003, while demand increased by less than 200,000 tons. There is already an oversupply, and with new production lines coming online continuously, the supply generated by these new lines exacerbates the problem. Although BOPP film is currently in a downturn and it seems there is an oversupply of this product, China’s per capita consumption level is not high compared to that of developed countries. With proper adjustments, and in line with the laws of market development, if BOPP manufacturers can accurately position their markets and products, then, given the current production capacity and the rate of demand growth, it is possible for this industry to emerge from its downturn around the first half of 2007, without the need for further large-scale expansion. Rising raw material prices and shortages: As is well known, the B0PP industry is a sector that consumes large amounts of electricity on a continuous basis, and price adjustments based on time limits and quotas only serve to exacerbate the difficulties faced by these companies. B0PP is also a manufacturing enterprise with high transportation volumes, and overloading occurs from time to time. The measure introduced by the central government this year to address the problem of overloaded freight trucks over a period of two years was originally a good thing, but it has at the same time increased transportation costs for B0PP manufacturers. From 2002 to 2004, new production facilities were put into operation across the country, adding approximately 1.5 million tons of capacity. This led to a severe shortage of raw materials. Coupled with increasing uncertainties in the international oil market for the companies that supply these raw materials, prices for raw materials both domestically and internationally kept rising sharply, rendering the already marginally profitable BOPP industry unprofitable. As B0PP processing enterprises, most of them produce goods on demand and basically have no inventory. If there are problems with the suppliers of raw materials or if funding is insufficient, it becomes impossible to supply the necessary raw materials in a timely manner, which affects the normal progress of production. The product development capability is low. Since the introduction of production lines, over 20 years have passed, during which equipment has been updated rapidly – from low speed to high speed, from narrow membranes to wider ones, and with an increasing number of membrane layers. However, our ability to digest and absorb these technologies after introducing them still needs further improvement. Even after more than 20 years, there are very few companies that possess their own intellectual property; they continue to produce ordinary products and rely on price wars to maintain their market share. For high-end devices with five layers, due to technical limitations and capacity constraints, it is not possible to fully utilize their advantages; as a result, only ordinary three-layer products can be manufactured, which makes these products less competitive. Blind expansion and repeated introductions of new production facilities led to waste of resources. Before 2002, the profit margin in the BOPP industry was generally above 20%, with better-performing companies achieving profits of over 30%; it could thus be considered an industry with extremely high profits. Coupled with promotional efforts in various media, the industry’s potential for growth seemed enormous, which prompted many companies to enter this field in a rush, without considering the development pace of industries at the downstream end. Between 2001 and 2002 alone, more than 30 new production lines were put into operation, resulting in an additional production capacity of over 600,000 tons. Originally, the normal annual growth rate for BOPP demand was only around 10%, but capacity increased at a rate of 50%, resulting in an oversupply of BOPP products. Equipment was operated at about 80% capacity, leaving some equipment idle and leading to waste of resources. This also increases costs and reduces profit margins. A way out for the BOPP industry in its current difficulties: At present, BOPP film production lines are still under construction in China, and their total output is more than twice the current domestic demand for BOPP film, resulting in an oversupply. With fierce market competition, how to achieve growth in such an environment is the primary issue that BOPP film manufacturers need to consider. Strengthening internal management and reducing costs: As BOPP companies are mostly new enterprises, it is necessary to adopt advanced management methods to enhance their resilience and build stronger, more efficient organizations. By taking into account the actual conditions of the enterprise, advanced management methods are introduced and integrated into its operations, thereby laying a solid foundation for improving product quality, reducing raw material consumption and manufacturing costs, and advancing toward larger-scale and more efficient operations. Only in this way can costs be reduced and product competitiveness improved. Leverage the resources of large enterprises to drive technological innovation. It is necessary to determine the market positioning of one’s products and develop appropriate marketing strategies. Currently, the BOPP industry faces a significant imbalance between supply and demand, with intense competition – it’s a truly fierce environment. But I need to calm down and think things through; I shouldn’t produce blindly. I need to figure out which varieties are in excess, which ones have a balanced supply and demand, and which ones are in short supply. Then, based on my own strengths, I should find… ; Determine the market positioning of its own products. Develop appropriate marketing strategies for different customers, market environments, and competitors. Increase the intensity of technological innovation, and establish sound information systems to understand the patterns of market development. Many domestic companies recruit talented individuals, focus on the development of new products, and offer generous rewards to those who contribute to such product development, thereby fostering the growth of their businesses. It is also important to conduct thorough market research to gather market information, which includes understanding customer demands, the current state and trends of the industry, as well as the market conditions in upstream industries. Through market segmentation, understand the development of customer diversity. Meeting personalized needs is one of the good strategies for small-scale BOPP production companies.
