Problems solved by technology

[0002] Fresh-keeping film and fresh-keeping bags are commonly used plastic packaging products for fresh-keeping food. Now many families cannot do without them. However, the current fresh-keeping bags have many disadvantages. The inner wall of the center is often full of water droplets, which will cause the decay of vegetables and fruits as time goes by, and because it is colorless and transparent, it can only be used indoors or in a cool place, and it is easy to cause food deterioration when exposed to direct sunlight. Paper fresh-keeping bags can't keep the moisture of fruits and vegetables, and neither PE fresh-keeping bags nor paper fresh-keeping bags can be antibacterial, which will easily cause pollution of fruits and vegetables, which is inconvenient for people's lives

Embodiment Construction

[0013] Preferred embodiments of the present invention will be described in detail below.

[0014] A specific embodiment of a double-layer antibacterial fresh-keeping bag and its processing method of the present invention: a double-layer antibacterial fresh-keeping bag, comprising an outer layer and an inner layer, the outer layer is a paper material containing Enteromorpha fiber, and the paper The mass ratio of enteromorpha fiber and paper pulp in the quality material is 1:20, and described inner layer is plastic film, and described plastic film is connected with paper material by laminating, and the thickness of described paper material is 0.9~1.2mm, The thickness of the plastic film is 0.3-0.6mm. The parts by weight of each raw material in the plastic film are: 100 parts of LDPE particles, 2-3 parts of semi-deacetyl chitosan, 3-5 parts of nano-silver particles, 0.3-0.4 parts of deoxidizer, 0.3-0.4 parts of corrosion inhibitor share. A method for processing a double-layer a...

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.
