According to a survey of food packaging containers conducted by a US market research company, the annual growth rate of paper containers in the past five years (19982003) was 3.2%, the annual growth rate of metal containers was 2.5%, and the annual growth rate of glass containers was 0.5. %, while the annual growth rate of plastic containers reached 5.5%. By 2003, plastic packaging accounted for nearly 30% of the total market for food packaging containers. The driving force behind the high growth of the plastic packaging container market lies in the improvement and recycling of resins and their processing methods. expand. At the same time, it is also related to many factors such as the reduction of material production cost and the improvement of product performance and production efficiency.
According to the prediction of China's authoritative departments, in the next two years, the sales of plastic flexible packaging in the food industry will exceed nearly 50% of the packaging industry's sales. It is expected that the overall development speed of flexible packaging will be slightly faster than the growth rate of the total national products.
Since the plastic material has excellent barrier properties, UV resistance, freeze resistance, heat resistance, etc., the application market is broad, especially the beverage and dairy products industries have attractive business opportunities. The application of plastics in aseptic packaging provides a space for the development of plastic packaging materials. At the same time, the improvement of plastic packaging materials will also promote the development of aseptic packaging in China.
From the perspective of environmental protection: China's State Environmental Protection Administration clearly stipulates in the definition of one-off fast food and beverage environmental labeling products: easy to recycle materials such as polypropylene (PP), high impact polystyrene (HIPS), Biaxially stretched polystyrene sheet products and high-filled natural inorganic mineral-filled polypropylene are among the environmentally-friendly materials. At present, most of the plastic materials used in liquid milk packaging in China are environmentally friendly materials.
From the trend of international food packaging development, five of the top ten development directions of US food packaging are mainly plastic packaging, the first of which is: for most new packaging, mainly based on petrochemical products. The third plastic can and plastic bottle will replace glass products, and in some cases can replace metal products, and will reduce packaging costs by improving the performance of packaging materials, rather than one-sided pursuit of price reduction; packaging lightweighting will Will continue to make progress; the promotion of filling packaging, etc. It can be seen that the development prospect of plastic packaging in the food industry is very broad.
Hunan Wanrong Packaging Co., Ltd. put forward the advocacy of “cherishing resources and striving for the simplicity of dairy packagingâ€. This action is undoubtedly in line with the current trend and will promote the healthy development of China's liquid milk packaging industry. The company is positioned as a professional dairy packaging service provider. The products are mainly based on plastics, and continue to research, develop and improve the barrier properties of packaging materials, shading, matt milk film, pearlescent milk film, milky white milk film, steamed milk film. , PP, HIPS yogurt cup, three-layer co-extruded PS sheet, heat-sealed cup cover film, providing a series of solutions for liquid milk packaging of dairy production enterprises.
At present, in the development of liquid milk plastic packaging, it is necessary to overcome the various factors that hinder the development of plastic packaging materials such as the convergence of plastic packaging materials, weak scientific and technological development capabilities, and insufficient funding sources. Good new product. In the selection of liquid milk packaging, dairy processing enterprises, in addition to the principles of the company's market, product positioning and "safe, convenient, and inexpensive", the development trend of international and domestic food packaging market and related policies are also important factors to consider. .
In summary, the application of plastic packaging materials in liquid milk packaging with its functionality, environmental protection, light weight and low cost will undoubtedly have broad prospects. It is believed that after a period of integration, the dairy industry will develop healthier and plastic packaging will continue to improve and develop in the dairy packaging industry.
Analysis of the success of plastic packaging for liquid milk
With the rapid development of liquid milk in China and the development of new varieties, the packaging of products is becoming more and more important. At present, in the process of selecting liquid milk packaging materials, many dairy processing enterprises prematurely declare the “death penalty†for plastic packaging due to “white pollutionâ€, and attempt to cancel the flexible packaging of plastics in spite of the conditions and market demand of the enterprise. Some high-cost "development ideas" under the "paper" condition packaging, which is a kind of plastic packaging still plays an important role in the food industry with the continuous improvement of materials and processing technology.
