The application prospects of PET plastic bottles are increasingly favored by experts and manufacturers. The development of PET is rapid both domestically and internationally, and the market prospects for PET plastic bottles are promising. Since its emergence in the 1950s, PET has rapidly developed due to its excellent performance and cost-effectiveness advantages brought by large-scale industrial production, as well as its characteristics of hygiene, safety, lightweight, and easy recycling. In 2005, the global production of PET was 41 million tons, and it is predicted to reach 50 million tons in 2008. China started relatively late, but developed rapidly, with a production of 1.7 million tons. With the increasing demand in the domestic market, PET packaging containers have entered a new market field.
The use of PET polyester bottles began with carbonated beverages. As the number and variety of beverages continue to increase, the use of PET bottles continues to grow. Currently, the number of PET containers used worldwide has reached 150 billion, with carbonated beverages accounting for 38%. China's beverage production has reached 32 million tons, growing at a rate of over 20% per year, and PET bottles in carbonated beverage packaging have accounted for 57%; With the sudden rise of the domestic tea beverage market, the production of tea beverages has reached 3 million tons. Therefore, PET bottles for hot filling (85 ℃~90 ℃) have become the fastest growing variety due to their light weight (with a capacity of only 56g per 1L, 61g for aluminum cans, and 360g for glass); In addition, bottled water, including purified water, mineral water, and distilled water, has entered thousands of households with a production of over 5 million tons. The PET bottle market required is also a sunrise market with broad development prospects. In the past two years, there have been new breakthroughs in the use of PET polyester bottles for milk packaging internationally. Italy's pasteurized milk bottles have started to be packaged in PET instead of HDPE, solving the problems of odor and poor taste in polyolefin bottle packaging. The corresponding equipment for blow molding, filling, and capping is also solved by Sidele Company. In addition, the market demand for PET bottles such as edible oil, seasonings, soy sauce, vinegar, etc. is constantly increasing, providing them with great market space. At the same time, the PET beer bottle market harbors attractive business opportunities. China is the world's largest beer producing country, with a beer production of 32 million tons in 2006. Currently, glass bottle packaging is still the main method, while some breweries in countries such as the United States, Japan, and Europe have adopted PET packaging.
