Antibacterial active packaging material and preparation technology thereof

Abstract

The invention discloses an antibacterial active packaging material and a preparation technology thereof. The packaging material is composed of a base material and an antibacterial agent, wherein the antibacterial agent is prepared from the following components: naringin, monopotassium glycyrrhizinate, rosa laevigate michx brown, beta-apo-8'-carotenealdehyde, mesoporous carbon, corosolic acid and compound essential oil; the base material is prepared from starch, bamboo powder, vermiculite powder, bauxite, polylactic acid, polyethylene glycol, modified coconut fibers, ammonium persulfate-sodiumhydrogen sulfite and ethanol. The packaging material prepared by the preparation technology has wide antibacterial performance, and the tensile strength and the elongation at break have a relatively excellent level, so that the antibacterial agent has relatively good adaptability with the base material. Moreover, raw materials of the packaging material are green and safe; the antibacterial performance lasting time can reach 30 months or longer and the antibacterial active packaging material has a very good application prospect.

Description

technical field

[0001] The invention belongs to the technical field of packaging materials, and in particular relates to an antibacterial active packaging material and a preparation process thereof. Background technique

[0002] Antimicrobial packaging is currently one of the most promising active packaging methods. Antimicrobial packaging technology is a kind of antibacterial packaging technology that slowly releases antimicrobial agents to the surface of food to inhibit the growth and reproduction of microorganisms on the surface of food by adding antibacterial agents inside or on the surface of packaging materials on the premise of meeting the requirements of traditional packaging technology, effectively blocking spoilage bacteria and pathogenic bacteria. On the basis of infection, and further react directly with the surface of the packaged product or indirectly through the space medium, effectively reduce, inhibit, and delay the growth and reproduction of microorganisms ...
