The concept of green packaging
The packaging industry is developing rapidly. The concept of green packaging makes the development of the packaging industry move to a more standard, environmentally friendly and healthy path. So what is 'green packaging'? Hefei Eagle palletizer found that green packaging has two meanings: green packaging takes into account both environmental protection and resource regeneration. Specifically:
1. Packaging reduction. That is to say, the packaging should reduce the dosage as much as possible under the conditions of protection, convenience, sales and other functions.
2. The packaging should be easy to reuse or easy to recycle. This is the most practical step in the development of green packaging materials at this stage, and it is also the most active method of waste recycling. The polyester beverage bottles, milk bottles and glass beer bottles currently used can be reused many times. If it cannot be reused, it is decomposed as much as possible, melted and reshaped.
3. Packaging waste can degrade and decay without forming permanent garbage. The world is studying degradable plastics to solve the serious environmental problems caused by the current inability of plastics to degrade. The principle of degradation is to make the plastic split and degrade and reduce in the natural environment through the action of microorganisms in the soil and water or through the action of ultraviolet rays in the sun, and finally re-enter the ecological environment and return to nature in a non-toxic form.
4. Packaging materials should be harmless and non-toxic to humans and organisms. Packaging materials should not contain toxic elements, heavy metals, or the content should be controlled below the relevant standards.
5. The whole process of packaging products from raw material collection, processing, manufacturing products, product use, waste recycling, to the final treatment should not cause public health and environmental pollution.
