1. Safety, health and safety means that the package must have reliable protection function for the packaged goods. It is a basic function that any package must have. It has universality.
Hygiene means that the use of packaging must not cause harm to humans and livestock and meet the requirements of relevant hygienic standards. Different commodities have different requirements for the hygienic properties of packaging materials. This requirement is particularly important for foods and drugs.
2. The relationship between environmental protection packaging materials and the environment must be analyzed from the viewpoint of the life cycle. From the perspective of environmental protection, packaging materials are required to start from the raw materials, to the production, processing and use of packaging materials, and to the use of waste after use. The entire process of disposal (the entire life cycle) has a good adaptability to environmental protection. The emphasis here is on the whole process, not just on one or some links, that is, on the governance of “white pollution†and to prevent the pollution of packaging waste from the natural environment. It is very important and important for the development of green packaging. On the other hand, as far as the development of green packaging is concerned, it is not enough to simply deal with "white pollution" - the disposal of packaging waste.
3, to save resources, mainly refers to the conservation of materials and energy, of course, from a deep level, there are problems of saving human resources.
To carry out green packaging work, we must now pay attention to the following aspects:
(1) The development of green packaging cannot be limited to the treatment of "white pollution." Managing "white pollution" so that packaging waste does not cause harm to the natural environment is an essential condition for carrying out green packaging work; governance "white pollution" is an important aspect of developing green packaging, and governance "white pollution" is also just green packaging. One of the aspects, not the entire contents of the green packaging. The development of green packaging is a systematic project. We must seriously study the entire “life cycle†of packaging to eliminate the harm to the natural environment and human beings through the whole “life cycle†of packaging in order to realize our original intention of developing green packaging. The true green packaging achieves the goal of sustainable development and benefit for future generations.
(2) While carrying out the work of green packaging, while we are currently focusing on the disposal of packaging waste, we must incorporate clean production into the content of green packaging. Particular attention should be paid to the issue of the clean production of paper products and plastic products that have a large amount of use and have a great impact, and minimize the negative impact of the “three wastes†substances on the surrounding environment during the production of packaging materials. For example, as far as possible in the production process, there is no solvent-free compound process, co-extrusion process, and extrusion compounding process to replace the dry compound process to produce plastic composite packaging materials without the generation of three wastes, and the energy consumption is less; Without using some toxic and hazardous substances and carrying out production, it is necessary to do a good job of the three wastes treatment in production and to achieve discharge standards.
(3) Pay attention to the problems in the recycling of packaging waste. Recycling of packaging waste has made great achievements, but there are many problems. We must attach great importance to the problems that exist. Here are some representative examples.
For example, the problem of recontamination of the environment caused by the waste water from the washing of packaging waste. The current situation of direct discharge of wastewater from washing wastes without treatment is widespread. On the one hand, packaging wastes are recycled and reused, which reduces the environmental pollution caused by packaging waste, but at the same time it generates a large amount of waste water, which is environmentally friendly. Pollution may be even worse than environmental pollution caused by packaging waste. This method of sacrificing the environment and recycling waste materials is not desirable.
Another example is the rational use of recyclables from packaging waste, which is also a question worthy of exploration and attention. At present, a large number of recycled materials of "undetermined sources" of packaging waste are used to make packaging materials that are in direct contact with food. For example, in Shanghai, a large number of recycled polyethylene shopping bags are produced. In the farmers' market, they are used to package fruits and vegetables, and meat. As for foods such as aquatic products and other foods, whether or not they were packaged with pesticides, chemical fertilizers, and other substances that are toxic to the human body are unknown in their previous applications, and these materials are used to make bags. The enormous potential danger to human health from food can be imagined. I once questioned the application of black vest bags in food packaging in the internal publication of “Green Packaging and Environmental Protectionâ€. Here again, I hope to The attention of relevant parties.
(4) Increase scientific and technological input and continuously improve the environmental adaptability of packaging materials. For those varieties with excellent performance and poor environmental adaptability, such as excellent gas barrier properties and excellent moisture resistance PVDC, the effect is remarkable in the packaging of food and medicine, but its adaptability to environmental protection is poor. : Poor thermal stability, difficulty in recycling, and toxic and hazardous substances such as hydrogen chloride and dioxins during incineration treatment; scattered in nature or buried in the ground and difficult to degrade, is an advantage and disadvantage. Outstanding varieties, for such packaging materials, before there is no better material to replace, it is recommended to control the use of them (you can not use the case, try not to use, use it as much as possible) It also organized efforts to strengthen the research on the collection, utilization and harmless disposal of its packaging waste.
