Problems solved by technology

The current packaging industry says that the number and types of packaging substrate films required are large, and it is difficult to adapt to special packaging requirements for films produced with a single raw material
However, the existing packaging plastic film still has the disadvantages of poor stretchability and water resistance. Therefore, we propose a plastic film with water resistance and its preparation method

Abstract

The invention discloses a waterproof plastic film and a preparation method thereof. The waterproof plastic film comprises, by weight, 42-44 parts of polyvinyl chloride, 25-27 parts of epoxy resin, 18-20 parts of polyurethane resin, 56-58 parts of acetone, 53-55 parts of ethylene glycol, 3-5 parts of borax, 4-6 parts of light calcium carbonate, 9-11 parts of ASA high-rubber powder, 13-15 parts of polyamide wax powder, 5-7 parts of trehalose, 12-14 parts of tartrate and 1-3 parts of stabilizer. The waterproof plastic film and the preparation method have the advantages that the raw materials arecompounded to achieve a synergic effect, and the plastic film is good in tensile strength and water resistance; the preparation method is low in production cost, simple in production process and beneficial to industrial production; the plastic film can be produced into various plastic-film packaging bags and is high in practical value and market popularization value.
