Analysis on the development and current situation of bottle grade polyester for edible oil bottles

with the improvement of people's consumption awareness and the consumption trend of pursuing the transparency and cleanliness of packaging, polyester (PET) bottles with many advantages, such as transparency, non-toxic and tasteless, not easy to break, good oil resistance, high ability to block oxygen and ultraviolet radiation, can protect edible oil from oxidation, long-term preservation and non deterioration, are conducive to the wider promotion of degradable green packaging materials, It is more and more popular in the field of edible oil packaging

at present, the six corners of the bolt and the screw part and the pitch diameter and the screw part will be deformed. About 10% of the domestic edible oil is packed in polyester bottles of 5L or less according to the market prediction. The annual consumption of polyester exceeds 40kt, gradually replacing HDPE and PVC, and becoming the preferred packaging material for small packaged edible oil

current situation of bottle grade polyester

the development of bottle grade polyester in the world began in the 1970s, but it failed to achieve rapid development due to imperfect technology and post-processing. In the 1980s, due to the continuous maturity of production technology and the large-scale production of post-processing equipment, bottle grade polyester has made great progress. In 1990, the first 12kt bottle grade polyester production line in China was put into operation in Shantou ocean. Other domestic manufacturers (such as Yihua, Yanhua, Changzhou Huayuan, Shanghai far East, Zhuhai Yuhua, etc.) also developed bottle grade polyester products and put them into production

by 1998, the domestic bottle grade polyester production capacity had reached 0.2 MT, basically in line with the demand. After 1998, due to the Asian financial crisis in 1997, Southeast Asia and even the global economy were hit hard, and the economic growth of major industrialized countries stagnated. China has made remarkable achievements in economic growth due to its active economic policies. Therefore, global companies such as Coca Cola, Pepsi Cola, Danone Group, Dingxin international and uni president group have increased their investment in the Chinese market, At the same time, the rise of domestic beverage enterprises such as Wahaha, Nongfu Shanquan, Jianlibao, etc. has led to a rapid increase in the demand for bottle grade polyester in the domestic market, with an increase rate of more than 30% per year, and bottle grade polyester has made extraordinary profits. From 1998 to 1999, the price difference between bottle grade polyester and fiber grade polyester was 2000-2500 per ton. Driven by this high profit, domestic polyester enterprises have stepped into the production of bottle grade polyester, and its production capacity increased from 0.2Mt in 1998 to 1.57 MT in 2003

at the same time, due to the sustained, stable and high-speed development of the domestic economy, people's consumption of beverage related products is also increasing, which has led to a large increase in the demand for bottle grade polyester. From 1996 to 2002, the contradiction between supply and demand of domestic bottle grade polyester was small, and the total demand was slightly higher than the production capacity. However, in 2002, due to the new production capacity of bottle grade polyester of nearly 0.6mt, the supply far exceeded the demand, and the market competition became extremely fierce

development and current situation of small packaging of edible oil

(I) edible oil consumption shows rapid growth

with the rapid development of domestic economy and the improvement of people's living standards, the rapid development of food processing industry, catering industry, tourism and related industries, the demand for edible oil is also growing rapidly. In 1993, the total domestic consumption of edible oil was 7mt, with a per capita consumption of 6.87kg; In 1998, the total consumption was 11.3mt, with a per capita consumption of 8.47kg; By 2003, the annual consumption of domestic edible oil had reached 13mt, and the per capita consumption had also increased to 9.98kg. This means that the domestic per capita oil consumption increases by 1.5kg every five years, showing a straight-line upward trend. However, despite this, this figure is still much lower than the per capita consumption of 32kg in the United States, 20kg in Europe, and even less than 2/3 of the per capita consumption of 15kg in Singapore, Hong Kong and Taiwan. It can be seen that the domestic edible oil market has great prospects and market potential

(II) the rapid development of small packaged edible oil

with the continuous improvement of the living standards of urban and rural residents, especially large and medium-sized cities, new concepts such as safety, hygiene, health and nutrition are becoming more and more prominent in the development trend of edible oil consumption, which makes the small packaged edible oil in a high-speed development stage, and the consumption increases at an average rate of 25% per year. By 2000, the small packaged edible oil accounted for 10% of the sales of edible oil. In some large and medium-sized cities, the sales volume of small packaged edible oil reaches 50% - 60% of the total sales volume of edible oil. If calculated by 10%, the bottle grade polyester used for small package edible oil can reach more than 40kt

in foreign countries, small packaged edible oil accounts for 30% - 35% of the total edible oil market, and the market potential is huge. In 2002, Shanghai "sea lion" edible oil launched a variety of small packaged edible oils for different consumption levels, reversing the difficult situation of operation in one fell swoop, making its edible oil sales rise by 50% year-on-year, seizing "half" of the edible oil market in Shanghai, and its production of small and medium packaged edible oil increased from 10% to 40%

(III) bottle grade polyester replaces other materials

before 1999, small packaged edible oil was basically packaged with HDPE and PVC. Since 1999, polyester bottles have advantages over HDPE and PVC in transparency, smoothness, no odor, hygiene and so on. At the same time, polyester has good extensibility and strength, which makes up for the disadvantage of low material consumption and high price. It has been recognized by major domestic edible oil production enterprises, and a large number of polyester bottles are used as the packaging of small packaged edible oil. Except for some special requirements, such as Fulin menwei a oil and other varieties, the vast majority of small packaged edible oil uses polyester bottles, which is also the current situation for a long time in the future

(IV) comparison of polyester bottle making equipment

in previous years, most domestic edible oil polyester bottle production enterprises were private enterprises, and the equipment used were domestic injection molding machines and bottle blowing machines, which were mostly produced manually or semi automatically. Its one-time investment, maintenance costs, labor costs and other aspects are relatively low, but the disadvantages are miscellaneous materials, unstable product quality, and unsatisfactory transparency, odor, hygiene and other aspects. Subsequently, large domestic oil enterprises such as Kerry Group (golden dragon fish) and COFCO group (Fulinmen) increased their investment, introduced large foreign injection molding machines and bottle blowing machines, and adopted bottle grade polyester that met the requirements. Their products were effectively guaranteed in terms of quality, transparency, hygiene and so on

current situation and development of bottle grade polyester for edible oil bottles

the continuous expansion of domestic bottle grade polyester production capacity has far exceeded the speed required by domestic beverages, and the contradiction between supply and demand is becoming increasingly prominent. However, the demand for polyester for edible oil bottles has increased rapidly, and its peak demand season is just in the off-season of other kinds of bottle grade polyester, with strong seasonal demand complementarity, which provides opportunities for domestic bottle grade polyester production enterprises to develop new products

most of the original edible oil polyester bottles used bottle grade polyester for the production of mineral water bottles, and even a considerable number of manufacturers chose super fiber Dimensional polyester whose hygiene requirements could not meet the national requirements, and their products were insufficient in transparency and strength. Changzhou Huayuan redys Co., Ltd. was the first to develop bottle grade polyester for edible oil. Its brand name is wb-8863, which was immediately recognized by oil bottle manufacturers after it was introduced to the market and maintained air circulation quickly; Open and occupy the market. Subsequently, bottle grade polyester manufacturers such as Yizheng Chemical fiber and Zhuhai Yuhua also successively developed and launched special materials for oil bottles

although all major bottle grade polyester production enterprises have developed and launched special materials for edible oil bottles, at present, a considerable number of small and medium-sized oil bottle manufacturers in the market still use super fiber Dimensional polyester or its tackifying products due to price factors, and their health indicators cannot meet the corresponding national requirements. The national health supervision department also noticed this phenomenon. In 2002, it made a corresponding investigation on oil bottles and bottle grade polyester and confirmed the hygienic inspection standard of oil bottles

with the continuous improvement of national laws and regulations and the continuous strengthening of law enforcement, small and medium-sized oil bottle manufacturers will eventually give up using super fiber Dimensional polyester or its tackifying products and use bottle grade polyester that meets the national food hygiene laws and regulations
