1.The static electricity of plastic film
Insulating material friction, easy to produce static electricity; the higher the insulating properties of the object, the more likely to produce static electricity. Plastic products usually belong to high insulating substances, especially packaging film used in large quantities of various plastics, in addition to polyvinyl alcohol and a very few other varieties, are highly insulating substances, and therefore very easy to produce static electricity problems.
2. anti-static, conductive packaging materials classification
The generation of static electricity, and the insulating properties of the object has a direct correlation, at the same time, different items on the packaging film antistatic requirements are not the same, some commodities not only need to have a general antistatic properties, but also need to be highly antistatic, and even require a certain degree of electrical conductivity, and therefore need to be based on the packaging materials of the resistance of the different anti-static film for specification and classification.
3. The need to develop antistatic film
Static hazards is a relatively common problem in people's lives, large such as flammable, explosive substances due to static electricity caused by fire, explosion, small such as objects due to static electricity caused by dust and dirt absorption, etc., are related to the electrostatic effect. With the development and application of plastics, synthetic rubber, synthetic fibres and other synthetic polymer materials, in people's lives, the use of insulating materials is becoming more and more widespread, static hazards are more and more, in order to improve the quality of life, people are also paying more and more attention to the prevention of static electricity, the development and application of anti-static film is also based on the realities of such a background. Is a highly insulating material packaging film, in the processing, application of static electricity and cause all sorts of disadvantages of the case has been commonplace. For example, in the use of film packaging, such as laundry detergent powder powder commodities, often because of static electricity on the heat sealing surface dust, resulting in a substantial decline in the sealing strength, caused by the storage of commodities, transport, packaging and serious damage in the process of an important reason. Another example of transparent plastic bags packaged goods, on the shelf display sales, due to electrostatic dust absorption to reduce the transparency of the packaging, thereby significantly reducing the packaging on the display effect of goods.
Packaging film in the printing process, may also be due to the film's electrostatic effect caused by the defects of the printed pattern, such as film static dust-absorbing effect of ink transfer, so that the print appears on the "flower point"; ink with static electricity caused by the so-called uneven ink on the so-called "electrostatic ink spot" and the Static electricity "ink whiskers". Anti-static film is often one of the basic conditions for the smooth operation of high-speed packaging production lines, such as cigarette packaging process, static electricity on the film cutting, conveying, stacking and other processes will have a negative impact, and even make the packaging machine can not run normally.
In particular, it should be mentioned that in recent years, with the rapid development of the IT industry, integrated circuits, components and their products are also a large number of applications of inexpensive film packaging materials packaging, if the use of static electricity prone to film packaging, will be due to film electromagnetic induction and friction generated by the accumulation of static electricity on a variety of sensitive electronic components, instrumentation, etc. to produce high-voltage discharge, so that the packaged goods have been destroyed, resulting in great economic losses, therefore, anti-static packaging. Economic losses, so the antistatic film as a functional plastic packaging film of a practical variety of people's attention, has been the rapid development.
According to the size of the plastic surface resistivity, some people also roughly divided into plastic dust level, antistatic level, conductive level, electromagnetic shielding level several levels.
3. The need to develop anti-static film
Static hazards is a relatively common problem in people's lives, large such as flammable, explosive substances due to static electricity caused by fire, explosion, small such as objects with static electricity caused by dust absorption finger, etc., are related to static electricity effect. With the development and application of plastics, synthetic rubber, synthetic fibres and other synthetic polymer materials, in people's lives, the use of insulating materials is becoming more and more widespread, static hazards are more and more, in order to improve the quality of life, people are also paying more and more attention to preventing the problem of static electricity, electrostatic film development and application is also based on the realities of such a background.
