[Chinese Packaging Network News] It is reported that in order to reduce the harm of packaging waste to the environment, China put forward the concept of "green packaging" as early as 10 years ago. Green packaging takes into consideration both the protection of the environment and the regeneration of resources, specifically:
1, reduce the packaging. That is, packaging should meet the requirements of protection, convenience, sales, etc., and the amount should be reduced as much as possible.
2. The packaging should be easy to reuse or easy to recycle. This is the most practical and feasible step in the development of green packaging materials at this stage, and it is the most active approach to waste recycling. The currently used polyester beverage bottles, baby bottles, and glass beer bottles can be reused many times. If it cannot be reused, it is decomposed as much as possible and melted to reform.
3, packaging waste can degrade and corrupt, does not form permanent waste. Degradable plastics are being studied all over the world to solve the serious environmental problems that plastics cannot degrade today. The principle of degradation is through the action of microorganisms in the soil and water, or through the action of ultraviolet rays in the sun, so that plastics are split, degraded and reduced in the natural environment, and eventually enter the ecological environment in a non-toxic form and return to nature.
4. Packaging materials should be harmless and non-toxic to humans and organisms. The packaging material should not contain toxic elements or heavy metals, or the content should be controlled below relevant standards.
5. Packing products shall not cause any pollution to the human body or the environment from the collection, processing, manufacturing of products, use of products, recovery of wastes, and up to the final treatment.
