The consumption of plastic packaging is the largest consumption in plastic consumption, with various styles and rapid technological updating. At the same time, the development of plastic packaging machinery industry is growing with the development of packaging plastic consumption. The prospect is good, and domestic and foreign market potential is huge.

 

In the plastic industry of the world, the largest amount of packaging plastics, generally accounted for 25%-70% of the total amount of plastic, takes the most developed plastics industry in America, Japan and Germany as an example. The packaging plastics account for 27.2%, 32.8% and 27.2% of the total plastic consumption, while China's plastic packaging accounts for about 25% of the plastic consumption.

 

Development prospect of international plastic packaging materials

 

1. plastic packaging has become one of the fastest growing materials in the packaging industry.

 

Internationally, although plastic packaging has been experiencing serious environmental challenges, it is hoped that plastic packaging is still one of the fastest growing materials in the packaging industry from the data published in recent years. In the United States, the average growth rate of paper and plastics in the field of packaging in the United States was 2.4% in the past 19962001 years, of which plastic was 3.4%, and the sales volume of plastic packaging materials in Japan accounted for 15.4% in the total sales of all kinds of packaging, which was second.

 

2. high barrier and multi-functional plastic packaging materials have become hot packaging materials in many countries.

 

This kind of material includes high permeability, multi-functional freshness, selection of air permeability, heat resistance, aseptic (antibacterial), antirust, deodorization, shape memory, re sealing, easy opening and other plastic packaging materials, with the development of high hinder permeability and multi-functional fresh-keeping, aseptic packaging materials and so on, will become the early twenty-first Century. The focus of development.

 

3. energy saving, environmental protection and recycling are the starting points of technology development.

 

Twenty-first Century is the century of environmental protection, plastic packaging materials will usher in a new opportunity, and will also undergo severe challenges. In order to meet the requirements of the new era, the plastic packaging materials need to meet the increasing requirements of the quality and efficiency of the market packaging, and the need to further save energy and pay attention to recycling.

 

4. developing anti-static and conductive soft plastic packaging materials has broad prospects for development.

 

5. plastic blend, plastic alloy and inorganic material filled reinforced composite (ABC) will become tomorrow's plastic star.

 

Development trend of plastic packaging materials in China

 

Rapid development of biaxial tensile thin film on 1. composite substrate

 

At present, we should introduce high and new technology equipment, develop special polyester film, produce hot sealing film through multi-layer co extrusion technology, occupy fresh food and frozen food packaging market, and introduce the technology of heat shrinkable film for production and develop label film for polyester bottle.

 

2. high barrier and multifunctional films are developing towards new technological level.

 

The original composite film is developing deeper, and the technology of bag making and printing has reached a new stage, accelerating the pace of entering the color revolution. At the same time, the entire industry has been monthly offset, intaglio, flexible color system, promoting the development of soft plastic packaging materials to the depth, anti-counterfeit packaging film is developing in a new moon, is called the soft plastic packaging often open flowers.

 

3. the development of multi-layer co extrusion technology has changed the product structure of functional thin films and containers and adapted to the market demand.

 

With the development of market economy, daily necessities packaging, cosmetics packaging, food packaging, household electrical appliances packaging have put forward higher requirements. On the one hand, with the increasing sound of environmental protection, how to reduce the amount of waste to minimize the amount of garbage under the premise of satisfying the packaging function, thus presenting the packaging film and packaging container to the light quantized and thin-walled direction, the high barrier film based on dry method, and the use of adhesive and solvent in the process of production. The development of CO extrusion packaging film is easy and convenient. The development of CO extrusion technology in the world is very fast. The relevant data show that the co extrusion packaging film in developed countries accounts for 40% of the whole soft plastic packaging material, but we only account for 6%, and the dry process composite film is still the main part, the proportion of the two is not reasonable.
