Reuse is the highest level of environmental protection measures. Internationally popular reuse, reduction of weight loss, and recycling are recognized as the three principles of environmental protection. However, these three items actually have different degrees of environmental protection. Reuse is the highest level of environmental protection.
Reuse can maximize the life of products and materials. For example, glass bottles containing beer and condiments can be reused five times or more, and cans can only be used once and need to be recycled. Another example is beverage packaging. PET bottles are the most commonly used containers, and most of them need to be recycled after one use. For this reason, Europe has already begun to produce thick PET bottles, which can be recycled many times, while China is also making efforts to reduce weight. Similar to dairy products, glass bottles of milk or yogurt, bottles can be reused after drinking, while cartons and plastic cups can only be used once. The plastic turnover box is a common transportation and packaging method for beverages and beer and can be used many times. However, in recent years, many beer companies have switched to using disposable cartons. This is actually not an environmental protection practice.
Most composite materials are not environmentally friendly. Single-layer materials often fail to meet performance requirements. Therefore, paper and plastic are often used in the form of composite materials, such as composite paper containers and most plastic packaging bags for liquid food and beverage packaging.
In fact, composites are often not capable of recreating similar products. For example, a composite paper container is a composite of paper, plastic, aluminum foil, and a binder. After a single use, paper, plastic, and aluminum foil cannot be separated and can only be reconstructed into sheets for other uses. In fact, paper and plastic are actually shortened. And the "life cycle" of aluminum foil. Plastic bags made of PP, PE or PVC can be processed into plastic bags or used for the production of other plastic daily products after use, but if these materials are compounded with nylon or other high-barrier materials, they can only be incinerated after use. There is no value for re-use.
Lightening, weight reduction, and thinning can reduce the amount of packaging materials used. However, if a thicker single material can achieve the performance of thinner composites, then packaging using a single material is a more environmentally friendly practice. At this point, glass and metal packaging are undoubtedly more environmentally friendly.
To protect the “green packaging†for the protection of the environment and commercial interests, we must formulate reasonable policies. We must not only consider technical factors, but also consider the actual allocation of resources; we must not only consider costs, but also consider social benefits. “Green packaging†should be a package that is environmentally friendly from the processing of materials and products to the disposal of waste. It cannot be taken out of context. One-sided thinking that waste is easy to handle is “green packagingâ€, which is conducive to environmental protection.
If considering the whole process of manufacturing, use and recycling, glass and metal packaging are undoubtedly the most environmentally friendly materials and packaging products, but the reality is that the share of glass and metal packaging containers is shrinking. Because in modern society, whether a commodity can gain market recognition will be constrained by many factors.
The decrease in market share of glass packaging is because the glass is bulky and fragile and cannot fully meet the requirements of the modern society. The share of metal packaging is reduced because of the high cost of metal packaging and the inability to cater to young people's demand for transparent packaging; Although waste is easy to handle, China's forest resources are extremely scarce. In the face of such contradictions, consumers should realize that “environmental protection†is not a slogan but an action. To protect the environment, it may be necessary to lose some convenience and even pay a higher price. Because environmental protection as a whole is definitely not a matter that can reduce costs. Choosing "green packaging" often means paying more money.
Moreover, do not think that "green packaging" is all new products. Selecting "green packaging" is sometimes a return of choice, just like returning to nature.

No matter which kind of material, it consumes a lot of energy during the manufacturing process. There are a lot of "three wastes" in the papermaking process. The formation of acid rain is mainly related to the "three wastes" produced by papermaking. Last year, China shut down thousands of small paper mills because the waste water from these small paper mills seriously polluted rivers and lakes. Can not rule out some large foreign paper mills have a good "three wastes" treatment devices and measures, but in terms of the actual situation in China, among the four kinds of packaging materials, paper manufacturing process is the worst environmental protection. Metal plates will also produce “three wastes†in the manufacturing process, especially waste residue. However, relatively speaking, enterprises that can manufacture cold rolled sheet or aluminum plate for packaging are very large-scale metallurgical plants, and environmental protection measures are relatively complete. Similarly, the production of plastic resins can only be completed by large-scale petrochemical companies. Not only are the three resins generated during the synthesis of plastic resins less, but these modern companies also have stricter measures for environmental protection. The production of glass requires a lot of energy, and it also produces "three wastes", but the degree of harm is not high.
