Functional food packaging plastic film manufacturing technology of using a low temperature plasma process

摘要

1. the art that the invention defined in the claims; The present invention relates to, and more particularly useful functionality manufacturing technology of the plastic film for food packaging according to the manufacturing technique of the functional plastic material.; 2. The technical problem to be solved by the invention,; In general, food packaging plastic film is moisture and gas barrier properties, dew condensation prevention, printability, anti-microbial, such as is required for printing, such as in food freshness and trademarks. An object of the present invention to provide a method for imparting a method of improving the moisture and gas barrier properties of the conventional general-purpose plastic film, a method of improving the anti-condensation property and printing property and antibacterial.; 3. Resolution of the subject matter of the invention,; Using a low temperature plasma treatment process, the surface of a general-purpose plastic packaging material to a plasma of a reactive gas, or to coat the functional thin film by plasma polymerization. If you wish to give it an antimicrobial has is added after the ionic substitution reaction in the coating process by plasma polymerization.; 4. An important use of the invention,; The functional food packaging plastic film made by the present invention is used to maintain freshness during storage and distribution of food for long periods of time.
