Core reminder: After long-term struggle and openness to the world, China's plastics industry has formed a relatively complete industrial system and has become a basic material industry that keeps pace with steel, cement, and wood. As a new type of material, its application field has been far Surpassing the above three materials Since entering the 21st century, China's plastics industry has made world-renowned achievements and achieved a historic leap. In this era of environmental protection, is there still a market for plastic products?
After long-term struggle and openness to the world, China’s plastics industry has formed a relatively complete industrial system, and has become a basic material industry that goes hand in hand with steel, cement, and wood. As a new type of material, its application fields have far surpassed the above three. Since these materials entered the 21st century, China’s plastics industry has made remarkable achievements and achieved a historic leap. In this era of environmental protection, is there still a market for plastic products?
As one of the pillar industries of the light industry, the plastics industry has maintained a growth rate of more than 10% in recent years. While maintaining a relatively fast development rate, economic benefits have also been improved. The total output value of enterprises above designated size in the plastic products industry ranks third among the 19 major industries of light industry, achieving a product sales rate of 97.8%, which is higher than the average level of the light industry. Judging from the production of synthetic resins, plastic machinery and plastic products, they all show the strong development momentum of China's plastics industry. From January to December 2007, China's plastic products enterprises achieved a cumulative industrial output value of RMB 80,181,565,700, an increase of 27.06% over the same period of the previous year; from January to October 2008, China’s plastic products companies achieved a cumulative industrial output value of RMB 788,006,448 thousand, which was a year-on-year increase. A year-on-year increase of 22.16%.
Plastic bottles use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, after high temperature heating, there are reports that the side effects of plastic mold materials indicate that long-term consumption is Food contaminated by ethylene molecules can cause dizziness, headache, nausea, loss of appetite, memory loss, etc., and even anemia. Therefore, using plastic bottles to pack vinegar is harmful to human health but not beneficial. Therefore, glassware should be used in the home instead of plastic products to contain condiments and so on. Pay special attention when using plastic products, do not touch vinegar, and clean plastic containers that have been blow-molded, extruded, or injection molded. It is mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oil, and agricultural and veterinary drugs. Plastic bottles are not easily broken, low cost, high transparency, and food-grade raw materials. Avoid direct sunlight, high temperature, etc. to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, less decorative patterns, colorless, odorless, and smooth surface.
With the development of plastic bottle packaging materials and packaging technology, plastic bottles are widely used in the packaging of cosmetics and detergents. They are cheap, rich in sources and plastic materials with good molding properties, and can be manufactured into plastic bottles of various structures and shapes.
Ordinary cosmetics and detergent packaging containers are mostly made of high-density polyethylene. Transparent packaging includes fully transparent packaging and partially transparent packaging. It is through transparent packaging materials that partially or fully Display the product form of the food inside, allowing buyers to directly see the image, color and quality of the food, which can reflect the natural beauty of the product. It is also convenient for customers to identify and purchase. Such as transparent plastic food bottles, candy cans, wine bottles, etc. at a glance, so that consumers can not help but donate money, sales soaring.
Since the transparent plastic bottle container allows consumers to see the contents clearly, consumers have more and more requirements for transparent PP plastic bottle containers, and transparent polypropylene is the main material to meet this requirement. The development of pp transparent packaging bottles It is a hot spot for plastic bottle packaging at home and abroad in recent years. Highly transparent polypropylene containers have good transparency and gloss, and are highly appreciated and popular.
In order to meet the packaging requirements of different products, the materials used for plastic bottles are becoming more abundant.
