As we all know, the prosperity of any industry will prompt the rapid development of other industries. The brutal growth of the electricity supplier industry has driven the boom of the logistics and express delivery industry. The prosperity of the automotive industry has spurred demand for the oil industry. In the same way, the increase in sales volume in the food industry will naturally make the food packaging industry progress together.
For food, packaging not only serves as a container, but also guarantees shelf life and extends the sale period. In the past, the food industry used a wide range of packaging materials for glass packaging, metal packaging, paper packaging and plastic packaging.
Because glass packaging and metal packaging are relatively expensive compared to plastic packaging and paper packaging, they are also cumbersome. In addition to special foods, most foods use paper packaging or plastic packaging. However, in the days to come, food packaging materials may increasingly be limited to paper packaging.
With the improvement of the social and economic level and the constant deepening of the level of civilization, the state and the government are paying more and more attention to environmental protection issues. In recent years, China has repeatedly introduced environmental protection policies, and local governments have successively enacted laws and regulations, which have greatly deepened the impression on the minds of environmental protection people. People's demands for environmental protection have naturally risen.
According to the survey, the amount of plastics used in food packaging accounts for 1/4 of the total plastic production. In supermarkets of all major shopping malls, foods in plastic packaging are commonplace. Plastic packaging used in expanded foods and plastic covering in instant noodles not only cause waste of resources due to excessive packaging, but also forms a lot of white garbage.
The amount of waste generated from such a large number of plastic packaging is inestimable and it is not easy to decompose. Landfilled in the soil, it is difficult to rot, causing great harm to land resources and water resources, that is, the use of fire burning, the gas produced will still pollute the air and damage people's health.
Therefore, at least in the high-end foods, plastic packaging in the future will be less and less, and as a substitute for paper packaging. Compared with glass packaging and metal packaging, paper packaging has lower costs, is easy to make, and lighter in quality and easier to process.
At the same time, compared with plastic packaging, paper packaging is easy to degrade and can also be recycled, with little impact on the environment. This occupies a great advantage in the rising awareness of the people's environmental protection, the zero packaging of the global industry and economic system led by the packaging revolution, the simple packaging, and the concept of green packaging.
In addition, paper packaging is moving toward the perspective of people's aesthetic appreciation. More and more people have found that the use of paper-wrapped items is not only fashionable and beautiful, but also reflects a refined and generous character. For example, in the past, plastic-packaged flowers were used in paper packaging on Valentine's Day or traditional festivals such as Tanabata Festival in recent years. This not only brings out the beauty of flowers, but also reflects the sense of high-end atmosphere.
In the food industry, in addition to foods such as fried foods and milk drinks that were originally packaged in paper, desserts such as disposable lunch boxes and chocolates have also been gradually expanded into paper packaging. It can be foreseen that in the near future, under the global environment that calls for green packaging, the food packaging industry will usher in more opportunities, and paper packaging will become the main trend of the food industry in the future.
There are opportunities that naturally have challenges.
Changes in food packaging will also bring about certain reforms in the enterprise. Problems such as industrial transformation, thinking transformation, and method transformation will all gradually manifest in this wave of trends. How to find the blank spots in the industry, how to speed up technological innovation, how to enhance service improvement, and how to gain the upper hand in the industry are all challenges that are worth pondering.
Photovoltaic(PV) Ground Screw
PV ground screw is a new type of solar photovoltaic supporting product, suitable for various solar photovoltaic, wind energy and construction industries, such as solar power station pile foundation, billboard pile foundation, sign flag pile foundation, wooden house pile foundation, etc., suitable for Various geology, such as clay, Gobi desert, gravel, etc., are favored by industry counterparts for their high load performance, stability, anti-settling and pull-out properties.
PV Ground screw is also called spiral ground pile, hot-dip galvanized spiral ground pile
Product specifications
Outer diameter 60mm---3000mm carbon steel Inner diameter 20mm---2500mm alloy steel
Pitch 60mm---3000mm stainless steel thickness 1.0mm---60.0mm
Detailed introduction:
Photovoltaic solar spiral pile is a kind of spiral drilling pile. Its characteristics include the connection of drill bit and drill pipe, drill bit or drill pipe connecting a power source. After this photovoltaic solar spiral pile is placed underground, it will no longer Take it out and use it directly as a pile.
The drill bit of the photovoltaic solar spiral pile includes the spiral drill bit at the bottom.
Specific structure:
1. Use steel pipe in the middle part
2. The top is the connecting pipe
3. The drill pipe of the photovoltaic solar spiral pile includes the upper connecting pipe
4. Steel rod in the middle part
5. The lower connecting shaft
6. After the pile is driven into the ground, it is no longer taken out, but used as a pile directly.
On the basis of the "end-bearing pile" structure and "friction pile" structure used in the construction process, it is widely used in the construction of a variety of ground piles, ground anchors, and randomly structured ground piles.
