Preparation and Properties Research of Anti-Fogging Polypropylene Packaging Films

Abstract:

The anti-fogging properties of a new anti-fogging agent containing silicon sprayed on polypropylene were discussed. The anti-fogging agent was prepared by using silicone hydride and silica sol, the new anti-fogging agent with different consistency was daubed on the polypropylene film .The contact angle, first dripping time and ten drippings time of the anti-fogging PP films were tested. According to the range analysis, the best mixture ratio, which was just the optimum formula was found. The relationship between the anti-fogging agent consistence and the anti-fogging performance was discussed too. The result showed that the anti-fogging properties of the coated film were better and the mechanical properties of the coated film enhanced in some sort. The mixture ratio of the anti-fogging agent was that the silica sol was 12phr; the span 80 was 15%; the pH was 5.5. After the film was coated, the tensile strength of machine direction raised by 109.14% than the contrast. The elongation at break of transverse direction raised by 32.51MPa and that of machine direction raised by 17.95MPa. This anti-fogging agent containing silicon was preferable to polypropylene.
