Abstract
Description
1. Technical field
[0001] The invention relates to a highly filled polyolefin composite film masterbatch, in particular to a highly filled polyolefin composite film masterbatch and a preparation method thereof. 2. Technical background
[0002] The plastic film is composed of polymer resins, among which high-density polyethylene, low-density polyethylene, linear low-density polyethylene and polypropylene are the main ones. With the price increase of oil, the cost of raw resin has increased, but the price of finished products has remained at a relatively stable level, causing the plastic film industry to fall into trouble.
[0003] In order to reduce the cost of the product, inorganic fillers are usually added to the resin, at the expense of part of the mechanical properties of the plastic film. However, at present, the filling amount of inorganic fillers in films in China is basically below 30%, and it is difficult to form them if the filling amount is above 30%, resulting i...
