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
The present invention relates to packaging bag manufacture field, be specifically related to a kind of double-layer antimicrobial freshness protection package and job operation thereof.
Background technology
Preservative film, freshness protection package is the plastic packing product of the class fresh-keeping foodstuff that people commonly use, a lot of family is had now all to be unable to do without them, but, current freshness protection package also exists a lot of drawbacks, PE freshness protection package is inwall often long-pending full water pearl in the process holding fruit and vegetable, prolongation along with the time also can cause rotting of vegetables and fruit, and due to its water white transparency, can only use at indoor or shady and cool place, easily food spoilage is caused by direct sunlight, and simple freshness protection package made of paper cannot keep the moisture of fruits and vegetables, and be that PE freshness protection package or papery freshness protection package all cannot be antibacterial, easily cause the pollution of fruits and vegetables, the life of inconvenient people.Invention describes a kind of double-layer antimicrobial freshness protection package and job operation thereof, it is by combining paper material with plastic sheeting, make it have the double dominant of paper material and plastic sheeting, both fruits and vegetables moisture loss can be prevented, the ventilative globule that not easily condenses again, and light tight can in outdoor application, the enteromorpha fiber in paper material and the nano silver material in plastic sheeting all have antibacterial action, prevent food by infected by microbes, health.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of double-layer antimicrobial freshness protection package and job operation thereof.
The technical matters that the present invention solves can realize by the following technical solutions: a kind of double-layer antimicrobial freshness protection package, comprise skin and internal layer, described skin is the paper material containing enteromorpha fiber, in described paper material, the mass ratio of enteromorpha fiber and paper pulp is 1:20, described internal layer is plastic sheeting, described plastic sheeting passed through to mould and was connected with paper material, and the thickness of described paper material is 0.9 ~ 1.2mm, and the thickness of described plastic sheeting is 0.3 ~ 0.6mm.
Preferably, in described plastic sheeting, shared by each raw material, weight portion is: LDPE particle 100 parts, half chitosan 2 ~ 3 parts, nano-Ag particles 3 ~ 5 parts, deoxidation reagent 0.3 ~ 0.4 part, inhibiter 0.3 ~ 0.4 part.
A job operation for double-layer antimicrobial freshness protection package, described processes step is:
(1) by after fresh Enteromorpha dehydration, be soaked in the sodium hydroxide solution of the 2mol/L of 10 times of weight, soak after 24 hours and filter, much filtrate is 120 ~ 150 DEG C in temperature, and pressure is the decatize 1 ~ 2 hour of pressurizeing under 0.1 ~ 0.2MPa condition, then takes out, polishing, pulp washing, leaches, and namely obtains enteromorpha fiber;
(2) join in paper pulp by enteromorpha fiber by allocation sheet proportion, fully after mixing, oven dry shaping through copy paper can obtain the paper containing enteromorpha fiber;
(3) by the allocation sheet of plastic sheeting, raw material is mixed rear single-screw extrusion machine and carry out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and haulage speed is 4m/min, and length-diameter ratio is 1:50;
(4) plastic sheeting after shaping is crossed by laminator on the paper moulded containing enteromorpha fiber, obtain double-layer antimicrobial freshness protection package material;
(5) double-layer antimicrobial freshness protection package material is passed through cutting, bonding, do pouch, get product.
Beneficial effect is: the present invention is a kind of double-layer antimicrobial freshness protection package and job operation thereof, it is by combining paper material with plastic sheeting, make it have the double dominant of paper material and plastic sheeting, both fruits and vegetables moisture loss can be prevented, the ventilative globule that not easily condenses again, and light tight can in outdoor application, the enteromorpha fiber in paper material and the nano silver material in plastic sheeting all have antibacterial action, prevent food by infected by microbes, health.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The detailed description of the invention of the present invention's a kind of double-layer antimicrobial freshness protection package and job operation thereof: a kind of double-layer antimicrobial freshness protection package, comprise skin and internal layer, described skin is the paper material containing enteromorpha fiber, in described paper material, the mass ratio of enteromorpha fiber and paper pulp is 1:20, described internal layer is plastic sheeting, described plastic sheeting passed through to mould and was connected with paper material, and the thickness of described paper material is 0.9 ~ 1.2mm, and the thickness of described plastic sheeting is 0.3 ~ 0.6mm.In described plastic sheeting, shared by each raw material, weight portion is: LDPE particle 100 parts, half chitosan 2 ~ 3 parts, nano-Ag particles 3 ~ 5 parts, deoxidation reagent 0.3 ~ 0.4 part, inhibiter 0.3 ~ 0.4 part.A kind of job operation of double-layer antimicrobial freshness protection package, described processes step is: (1) is by after fresh Enteromorpha dehydration, be soaked in the sodium hydroxide solution of the 2mol/L of 10 times of weight, soak after 24 hours and filter, much filtrate is 120 ~ 150 DEG C in temperature, pressure is the decatize 1 ~ 2 hour of pressurizeing under 0.1 ~ 0.2MPa condition, then take out, polishing, pulp washing, leach, namely obtain enteromorpha fiber; (2) join in paper pulp by enteromorpha fiber by allocation sheet proportion, fully after mixing, oven dry shaping through copy paper can obtain the paper containing enteromorpha fiber; (3) by the allocation sheet of plastic sheeting, raw material is mixed rear single-screw extrusion machine and carry out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and haulage speed is 4m/min, and length-diameter ratio is 1:50; (4) plastic sheeting after shaping is crossed by laminator on the paper moulded containing enteromorpha fiber, obtain double-layer antimicrobial freshness protection package material; (5) double-layer antimicrobial freshness protection package material is passed through cutting, bonding, do pouch, get product.
