The concept of green environmental protection has long been deeply rooted in people's hearts, relying only on the price of products, quality and other single product characteristics have been unable to meet the growing needs of consumers and enterprises. At this stage, many countries in the world are conducting research to replace packaging plastics on the existing market with "biodegradable resins". The "corn starch resin" successfully researched by Japan and Taiwan last year is a new type of green environmental protection material, which has broad market utilization prospects. This resin is made of corn as raw material, and is plasticized by processing, and the packaging materials made of it can be disposed of by burning, biochemical decomposition and insect feeding, so as to avoid the harm of "white pollution" and "plastic pollution". According to recent information from Taiwan Province, the number of plastic bags produced per ton of corn resin in Taiwan is almost the same as the number of plastic pellets produced. Taiwan plastics industry statistics, the world produces about 100 million tons of plastic products every year, of which 30 million tons of disposable packaging materials, to solve the pollution caused by these materials to spend a lot of social costs. If corn resin can successfully replace some of these packaging plastics, it is estimated that the market could be worth $10 billion a year.
At this stage, green packaging has not been popularized, the following aspects can also greatly reduce environmental pollution.
1. Avoid excessive packaging
The purpose of packaging is to protect the goods from damage, easy to transport, storage and consumer carry, on this basis, beautiful and generous, and conducive to the sale of goods. Proper packing is undoubtedly necessary and beneficial. However, the packaging with excessive functions such as protection, convenience, communication and decoration is excessive packaging, which makes the packaging go to the other extreme. On the one hand, excessive packaging leads to a waste of a lot of resources. Taking the packaging belt industry as an example, such as the packaging belt of pp, pet and other materials commonly used now, due to the light weight, often need multiple packaging operations, according to statistics show that developed countries use pp, pet and other materials packaging belt accounted for 30%, while China accounted for 80%, making our country spend more than one billion yuan a year to package, If you switch to polyester fiber packaging belt currently on the market rare environmental packaging belt, you can save 1/3 of the cost. On the other hand, excessive packaging has caused serious environmental pollution. At present, the annual emissions of packaging waste in China have accounted for 1/3 of municipal solid waste by weight, and the volume has reached 1/2, and the emissions are increasing at a rate of 10% per year. In addition, excessive packaging infringes on the interests of consumers, but also damages the interests of society. The wind of excessive packaging is easy to form a luxurious and grandiose social atmosphere, which is not conducive to the construction of a conservation-oriented society.
2. Material selection
The selection of green packaging materials is almost harmless to human health, has a good protective effect on the ecological environment and recycling packaging materials. However, as far as the current development prospects of green packaging materials are concerned, they are far from meeting the needs of the market. Instead, polyester fiber packaging belts have become the primary choice, and polyester fiber packaging belts have strong advantages in other aspects as well as environmental protection.
There are mainly the following points
Strong tension:
High tensile strength, can withstand 0.5-8.5 tons of tension, can replace the traditional steel strip.
High impact resistance:
Due to its ductility and resilience after deformation, polyester baling tape can absorb impact energy better than steel tape and does not become loose after the cargo contracts or expands.
High bonding strength:
The strapping belt is characterized by connecting steel buckle, which is one of the most solid connection methods and can be tightened repeatedly; In some applications, the buckle can be reused.
Safe to use:
It is lightweight and soft, do not need to wear gloves; When it is cut, it will not spring open, injuring transport workers and customers; Because of its soft texture, the used tape is also very easy to handle; There are no sharp corners, which will not damage the forklift tires during storage.
Do not harm the product:
The flexible texture protects the surface of the product from scratches.
No rust, no deterioration:
It can withstand changes in various weather conditions and will never stain your products.
Cost savings:
Considering the cost implied by all the steel tape, polyester baling tape is a very cost saving option;
Low cost of packaging tools - only a simple tool is required, and wear is minimal, and maintenance costs are low.
The necessity and positive significance of green packaging are mainly reflected in: the green packaging can reduce environmental pollution and maintain ecological balance. If a large number of non-degradable plastics are used in packaging, permanent garbage will be formed. The combustion of plastic waste will produce a large number of harmful gases, including the production of carcinogenic aromatic hydrocarbons; If a large number of wood packaging, it will destroy the ecological balance, so by adopting green packaging to protect the environment and maintain the ecological balance. Green packaging conforms to the needs of the international trend of environmental protection development. Driven by the wave of green consumption, more and more consumers are inclined to buy green products that are harmless to the environment. Products with green packaging and green marks are more easily accepted by foreign investors in foreign trade. Green packaging is the requirements of the WTO and related trade agreements in the WTO package agreement in the "trade and environment agreement", prompting enterprises in various countries to produce products and packaging that meet environmental requirements. Green packaging is one of the important ways to bypass new trade barriers The International Organization for Standardization (ISO) has formulated the corresponding standard ISO14000 on the environment, which has become an important non-tariff barrier in international trade. In addition, in May 1993, the European Community officially launched the "European environmental label", the import of goods in the European Community to obtain the green mark must apply to its Allies, and the products without the green mark will be greatly restricted to enter the above countries.
