Abstract

The invention discloses a printable plastic film and a preparation method thereof. Raw materials of the printable plastic film comprise 85-95 wt% of a resin material, 3-10 wt% of a conductive materialand 2-5 wt% of an oily material; raw materials for preparing the resin material include 70-80 wt% of polyethylene or polypropylene and 20-30 wt% of C5 petroleum resin; and raw materials for preparingthe conductive material include 10-20 wt% of carbon black, 15-25 wt% of graphite, 15-25 wt% of ferriferrous oxide, 15-25 wt% of carbon nanotubes and 20-30 wt% of metal powder. The printable plastic film prepared in the invention has the advantages of good printability, good stability and low production cost, and the preparation method has the advantages of simplicity, easiness in process operation, and suitableness for large-scale promotion.

Description

technical field [0001] The invention relates to the field of film production and processing, in particular to a printable plastic film and a preparation method thereof. Background technique [0002] With the development of modern packaging printing, printing plastic film has become very common, but in the printing process, because the surface characteristics of plastic are different from other substrates, and some properties of printing ink can not be well adapted to plastic products, so printing Quality is often inconsistent. Therefore, the quality of printable plastic films must be improved. However, among the plastic films used for single-layer packaging in the market, double-sided heat-sealing films are often unprintable, and the printable plastic films are generally of low quality or high production cost, which will directly affect the application range of the film. [0003] The invention patent with application number 201410764684.2 provides a printable double-sided ...
