The importance of building stretch film
The importance of building pallet stretch film
There are many forms of stretch film in China's chemical industry. Although currently aimed at the chemical industry, the mulch bag still occupies the main position. With the international and domestic restrictions on safety, environmental protection and resource conservation, the application range of traditional packaging forms will be smaller and smaller, which provides a good opportunity for the development of stretch film.
1.1 supply status and performance of mulch woven bags
Membrane woven bag as the main branch of woven bag, it carries on the woven bag the advantage of high tensile strength, but also has stretch film bag of good air tightness and moisture resistance, so it is a kind of typical compound packing materials. The composite film woven bag can be divided into outer composite and inner composite according to the composite method. At present, the most commonly used is internal compound, mainly with the following advantages.
1.2 supply status and performance of stretch film(bag)
As can be seen from table 1, at present, the stretch film project is mainly concentrated in the southeast coastal areas, while the vacancy is in the northwest.
China's pallet stretch film products are expected to grow by more than 10% during the 12th five-year plan period. It is expected that the recycling economy will become the main development model of the plastic packaging industry in the future, which also indicates the good development prospect of stretch film products.
1.3 comparison between stretch film bag and composite woven bag
For composite plastic woven bag production line, its advantages are: one is the source of raw materials mainly domestic raw materials, in terms of shanbei region, shaanxi oil group company in the production of polypropylene T30S as main raw material, plastic woven bag can be relatively low logistics requirements; Second, the technology content of this production method is relatively low, and in northern shaanxi, shaanxi petroleum group has 15 million per year woven bag production lines, mature production technology and equipment management methods. Third, as far as the present, plastic bags are widely used; Fourth, the production environment is not high. The disadvantages are as follows: first, the production process is long; Second, slow packaging speed; Third, more people are employed; Fourth, large energy consumption; The sales market is highly competitive. Six is to cover a large area.
For the stretch film production line, its advantages: 1. Second, the labor intensity of the workers is small; Third, fewer people are employed; Fourth, less energy consumption; Fifth, weak competition in the sales market; 6. Small land area; Seventh, environmental protection. Its disadvantages: first, the main raw materials needed for production need to be imported from abroad, high logistics requirements; Secondly, the proportion of raw materials is strict. The formula of raw materials also needs to be adjusted due to the seasonal temperature difference. Third, the production line is particularly strict with the environment. Fourth, small sales market; Fifth, the use unit needs to be matched with the corresponding filling packaging line. The necessity of building stretch film project in northern shaanxi province
The energy and chemical base of northern shaanxi was officially approved by the national development and reform commission in 1999. It is the only national energy and chemical base in China. Under the jurisdiction of yulin and yan 'an, the north shaanxi energy and chemical base covers a total area of 81,000 square kilometers, accounting for 45% of the land area of shaanxi province, and is the core area of China's ordos basin.
At present, there are many chemical projects of salt chemical industry and polyolefin chemical industry, so there is a large demand for packaging bags.
According to the situation, there is a gap of 260 million pieces per year in the demand for packaging bags in northern shaanxi. Therefore, the construction of stretch film is very necessary.
2.2 construction of pallet stretch film project is conducive to promoting industrial structure upgrading of energy and chemical base in northern shaanxi and improving product competitiveness
Stretch film for the construction of the project can effectively use of northern shaanxi energy chemical industry base in the production of polyethylene and other downstream petrochemical products, extend the industrial chain, improve chemical raw materials, its own economic added value at the same time, it can greatly enhance the external image of northern shaanxi energy chemical industry base and product added value, enhance its competitiveness in the market. The development of the project is also conducive to the adjustment of the industrial economy and industrial structure of the project site.
After the completion of the project, it can not only effectively transfer the local labor force, increase the income of local residents' labor services, improve their living standards, promote the development of local economy and stabilize social order. But also by the worker's job skills training, to improve the quality of the local human resources, make it to the market economy and knowledge economy, improve personal wealth and the ability to create wealth for the society, thus relatively long-term positive impact on local, promote local construction of new socialist countryside and harmonious society.
3. Environmental impact assessment of pallet stretch film construction
3.1 types of pollutants generated in the production process of stretch film
The pollutants produced in the production process are sewage, waste gas, solid waste and noise. Sewage is mainly the domestic sewage produced by the factory staff. Waste gas pollution is mainly the organic waste gas produced by the melting of raw materials and the volatile ink solvents in the printing process. Solid waste is mainly the secondary product produced by each section, the raw material packaging and waste ink barrels, and the household waste generated by the factory staff. The noise comes from the noise produced in the process of air compressor and air ring blowing.
3.2 pollution control measures during the production of pallet stretch film project
(3) solid waste disposal measures. The waste from the process can be recycled after granulation. Domestic waste is transported to designated landfills for intensive treatment. The waste ink barrel is recycled by the original factory.
3.3 environmental impact assessment
The construction project of pallet stretch film has little impact on the internal and external environment. From the perspective of industrial policy and environmental protection, the construction project meets the requirements of the environment.
It has been proved that building pallet stretch film in northern shaanxi province is feasible in market, policy and environment protection.
