1、 Generation of static electricity:1. Friction: In daily life, any two objects made of different materials can generate static electricity after contact and separation. The most common way to generate static electricity is to generate electricity by friction. The better the insulation of materials, the easier it is to use friction to generate electricity. In addition, static electricity can also be generated when objects of any two different substances are separated after contact.2. Induction:

1. Moderate maintenance characteristics According to the different regulations of packaging design, the sponge inner support should be able to reasonably maintain the commodities, so the sponge inner support should have certain compressive strength, rigidity, ductility and extensibility, so as to incorporate the hazards of working pressure impact, vibration and other factors, and solve the problems of moisture, water vapor, vapor, light source, fragrant gas, odor, calorific value, etc. and have certain isolation working ability.

From January to November last year, the total output of plastic products in China was 49,210,500 tons, a year-on-year increase of 21.11%. According to customs statistics, from January to September last year, the total import and export value of major commodities in the plastic industry was 37.338 billion USD, up by 12.92% compared with the previous year. From January to September, the export volume of plastic products was 8,657,100 tons, down 22.32% from 11,146,000 tons in the same period last year; However, the export value was USD 24.989 billion, and plastic boxes increased by 15.58% compared with USD 21.621 billion in the same period last year. The above statistics not only reflect the current situation of export decline and inflation, but also reflect the sustained growth of domestic demand.

With the continuous progress and development of society, people's demand for all kinds of electronic products is increasing, especially for communication products, such as new IPAD products and smart phones. Many young friends are scrambling to buy the latest models to use. Therefore, this has greatly promoted the development of electronic product manufacturers, and these manufacturers are faced with a very common and severe problem, that is, anti-static phenomenon. Therefore, anti-static pad products become their indispensable products, and these anti-static pad products can make many manufacturers develop better. At present, manufacturers of anti-static products have invested a lot of production costs. By using the very advanced high-tech technology at present, they have increased the innovation and production of anti-static mats, and produced

According to G3 comprehensive report, there are two kinds of profiles, one is all-plastic profiles, and the other is composite profiles made of plastic materials and non-plastic materials. According to the degree of hardness of profile, it can be divided into soft profile and hard profile. According to the classification of plastic varieties, it can be divided into: PVC profile, ABS profile, PE profile, etc., most of which are PVC profiles. According to the cross-section characteristics, the profile can be divided into 7 categories: profile pipe, hollow profile, plug profile, open profile, segmented profile, inlaid profile and solid profile. Due to the huge market demand and broad development prospects, plastic profile has developed rapidly in China in recent years. Due to the fierce market competition, all plastic machinery manufacturers are considering a problem: how to improve the productivity and qualified rate of plastic profile products on the premise of ensuring product quality,
