Strengthen recycling and reuse, and realize ecological recycling of packaging waste

During the entire life cycle of the green packaging, it follows the principles of economic activities of “reduction, reuse, and resource recycling” of the circular economy so that the impact of packaging on the environment is minimized. In recent years, progress has been made in the recycling and reuse of plastic waste, and the secondary pollution problem has been gradually solved.

Packaging waste regulations vary from place to place, but there is a common principle: encourage the use of raw materials. In the packaging design, the same material should be used as much as possible, the coexisting materials can be separated, and tends to use a material that is simple in structure and easy to recycle.

Under the premise of satisfying the packaging function, the amount of waste generated is reduced as much as possible to present a lightweight development trend for packaging films. The key technology is to use new materials that have super toughness, can be processed thinly and are easier to process, such as bimodal positions. Polymer HDPE, polyolefins with metallocene catalysts, and high-quality barrier packaging materials.

The domestic plastic flexible packaging industry has made many progresses in reducing waste pollution. With the gradual implementation of relevant domestic environmental laws and regulations, more progress will be made this year. For example, the use of heat-sealable stretched film plus varnish significantly reduces the amount of material used, has been used in a large number of applications for cold drink ice cream packaging, and has successfully reduced the thickness of the entire packaging film by using high-strength metallocene polyolefins. Overpackaging is also being gradually reduced; coextrusion compounding technology and equipment applications are becoming more and more popular, solving the problem of precise control of the thickness of each layer of the film, the barrier layer thickness of high price can be controlled very thin, and the freshness preservation performance is doubled Even dozens of times better.

With the greening of plastic flexible packaging, the plastic flexible packaging industry will achieve better and faster development in the new century.
