The plastic packaging industry is a global and continuously growing industry. With the recovery of the world economy and the rapid development of modern commerce and logistics industries, the packaging industry has rapidly risen globally since the mid-twentieth century. Due to the multiple functions of protecting commodities, facilitating circulation, facilitating consumption, promoting sales, and enhancing added value, packaging products have become more and more widely used in modern society and have become an indispensable part of commodity circulation.
1. Market size
China is a major packaging manufacturer and consumer in the world. Plastic packaging accounts for more than 30% of the total output value of the packaging industry, and it plays an irreplaceable role in various fields of food, beverages, daily necessities, and industrial and agricultural production. In recent years, our country's plastic packaging industry has been in a trend of steady growth, ranking second only to paper packaging in the proportion of packaging product structure.
1. The performance is more secure and stable
In order to ensure the safety of the food in the package, the performance of the packaging material is particularly important. For example, oily food requires high oxygen and oil resistance, dry food requires high moisture resistance, and aromatic food requires high aroma retention; The packaging of fruit and vegetable is required to have high air permeability. The packaging of drinking water requires stable air tightness and easy opening of the bottle cap. In addition, the packaging material must have high tensile strength, tear resistance, impact resistance, excellent chemical stability, and no chemical reaction with the inner food to ensure the safety of the contents.
2. The materials are environmentally friendly and recyclable
Environmentally friendly packaging can reduce environmental pollution and maintain ecological balance, which is conducive to building a low-carbon economy and a resource-saving society. The environmental protection of the plastic packaging box and container manufacturing industry is mainly reflected in the degree of recycling. Its main technologies are plastic recycling processing technology and easy-to-degrade technology. The high recycling of plastics can improve and eliminate the hidden dangers of white pollution caused by plastic packaging materials, and improve resource utilization. In the future, with the continuous research and development of new materials, new materials will not only give full play to the functions of packaging materials, but also reduce and eliminate the environmental pollution of plastic packaging materials, and improve the safety and environmental performance of plastic packaging.
3. The product is ultra-thin and lightweight
Under the condition of meeting the existing functions, the development of plastic packaging in the direction of lightweight and ultra-thin is the inevitable trend of future industry development. Lightweight packaging can not only reduce the consumption of packaging raw materials, but also reduce the unit energy consumption and cost of products in the logistics and transportation process, bringing considerable economic benefits to enterprises, and alleviating people's concerns about environmental protection and sustainable development. A win-win situation between the economic benefits of the enterprise and the public interest.
4. The production process is automated and intelligent
With the continuous improvement of the level of science and technology and the upgrading and adjustment of the industrial structure of my country's manufacturing industry, computer-assisted fully automated production lines are becoming the trend of industry development. The popularization of automated production technology has greatly shortened the production cycle and improved production efficiency, so as to meet the goals of maximizing benefits and minimizing production costs. Automation and intelligent technology produced in the plastic packaging industry will be the development trend of the industry.
