Description

Multi-material composite packaging materials bring difficulties in the classification, recovery, and recycling of such products. At present, there is still no effective method to separate and classify and recycle composite films of different materials. Land burial of waste packaging materials will cause soil barrenness and deterioration, and crop yields will be reduced or eliminated; the incineration of waste plastics will produce a large amount of toxic gases such as CO², CO and residual heavy metals in ash, which will increase environmental pollution and greenhouse effect; a large number of studies have found that marine organisms are Discarded packaging materials endanger life.

On the other hand, the good printing effect of consumer goods packaging and the high-quality requirements of consumers for visual perception, hope that the preservation period of food and daily chemical products will be prolonged without adding chemical substances, and there will be no odor and no peculiar smell.

Therefore, we research and develop pure polyethylene composite structures with functions and appearances that meet market demand. The inner and outer materials are mono-material, and the packaging materials that can be completely recycled and reused are realized, which is of great social significance.
