How to improve plastic packaging materials?

1. Innovate and develop new plastic materials and new processing technologies to make more excellent plastics into packaging materials, and use the high performance of new materials to achieve reduction of packaging materials;

2. Promote the progress and development of plastic blending technology, new plastic additives and application technology. Under the premise of ensuring non-toxic, hygienic and environmental protection of plastic packaging materials, low-cost technology is used to improve the performance of plastic packaging materials. Provide possible;

3. Improve and improve the recycling technology of plastics, so that the recycling rate of plastic packaging materials will be greatly improved, improve and eliminate the hidden dangers of “white pollution” caused by plastic packaging materials, and improve resource utilization;

4. Develop bio-based plastics, effectively regulate the degradation time and cycle of bio-plastics, and reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment while giving full play to the functions of bio-plastic packaging materials;

5. Through independent research and development and technological innovation, reduce the cost of new materials and technologies for plastic packaging, and avoid the problem that many plastic materials conforming to green packaging cannot be applied in a large area due to excessive cost;

6. Develop advanced packaging technologies such as intelligentization, and utilize the characteristics of edible and water-soluble of some plastic packaging materials to reduce the amount of packaging waste and improve the safety and environmental performance of plastic packaging.

At present, the proportion of plastic packaging in the packaging industry has exceeded 30%, making it a new force in the packaging industry, playing an irreplaceable role in various fields of food, beverage, daily necessities and industrial and agricultural production. The plastic packaging industry will present two major development trends in the future:

Plastic packaging will be green, and plastic packaging waste has caused widespread concern in society. Strengthen the scientific management and utilization of plastic packaging, maximize the recycling of waste plastics, and gradually develop and utilize degradable plastics. In China, biodegradable plastics have been greatly developed. It is imperative to vigorously develop and promote the use of biodegradable plastics. .

Plastic packaging will be lighter and lighter, reducing weight. Lightweight means producing packaging with less material, reducing weight on packaging, and being profitable for the environment and the business. Generally, plastic bottles and plastic cans Types of containers such as plastic hoses and plastic covers are easier to achieve weight reduction goals.
