Abstract

The invention discloses a double-layer anti-bacterial freshness protection package and a processing method thereof. The double-layer anti-bacterial freshness protection package comprises an outer layer and an inner layer. The outer layer is made of a paper material containing enteromorpha fibers. The mass ratio of the enteromorpha fibers and pulp in the paper material is 1:20. The inner layer is made of a plastic film. The plastic film is connected with the paper material through excessive plasticizing. The thickness of the paper material is 0.9-1.2 mm. The thickness of the plastic film is 0.3-0.6 mm. According to the double-layer anti-bacterial freshness protection package and the processing method thereof, the paper material and the plastic film are combined, so that the double-layer anti-bacterial freshness protection package both has the advantages of the paper material and has the advantages of the plastic film, the loss of moisture of fruits and vegetables can be prevented, the freshness protection package is breathable, and condensation of water drops is unlikely to occur; in addition, the double-layer anti-bacterial freshness protection package is not pervious to light and can be used outdoors; the enteromorpha fibers in the paper material and nano-silver materials in the plastic film both has the anti-bacterial function, so that food is prevented from being infected by microorganisms, and health and sanitation are guaranteed.

Description

technical field [0001] The invention relates to the field of packaging bag processing, in particular to a double-layer antibacterial fresh-keeping bag and a processing method thereof.
