Modification of the chemical modification of the plastic film

Chemical modification of polymer surfaces to improve the performance of a polymer barrier methods widely people's concern, but there is a barrier between the polymer is considered to be an ideal material for packaging. Polyolefin film despite poor gas barrier properties, but due to the low cost, high toughness, good processing performance, excellent barrier properties to water, and therefore attractive. Very suitable for surface treatment of the film, in the process because the surface modification or processing to easily processed to make a better barrier material.

The surface modification of the surface of the reaction gas without altering the performance of conventional polymer matrix. The reaction of the polymer surface with the gas can achieve this modification. Research has been surface-modified with fluorine, hydrogen fluoride, sulfur tetrafluoride, the chlorine and bromine.
