Description
Technical field
The present invention relates to food packaging food fresh keeping membrane, in particular to a kind of nano material preservative film.
Background technique
Currently, with the development of e-commerce, requirement of the people to food especially fruit and vegetables freshness is increasingly
Height, in the transportational process of fruits and vegetables, " fresh-keeping " is the index that people pursue jointly.It is usually at present to pass through cold chain
The mode of transport is fresh-keeping to achieve the purpose that, in this process, low temperature can reduce fruits and vegetables respiration, reduces self and disappears
Consumption, extends the freshness date of fruits and vegetables.Wherein, Cold Chain Logistics play a crucial role preserving fruit and vegetable utilizing, but Cold Chain Logistics at
This height, it is high to complete sets of basic equipment facility requirements, it also needs constantly to explore new preservation technology and means for now cold to make up
The deficiency in chain market.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of nano material preservative films that can be used for food packaging.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of nano material preservative film, the preservative film be followed successively by from the inside to the outside hot sealing layer, the first adhesive layer, barrier layer,
Second adhesive layer and outer layer five-layer structure；
The hot sealing layer is the mixture of polyvinyl resin and nano-functional material；
The barrier layer is nylon；
The outer layer is polyvinyl resin.
Preferably, the hot sealing layer thickness accounts for the 20-35% of overall thickness；First bondline thickness accounts for overall thickness
15-20%；The barrier layer thickness accounts for the 15-30% of overall thickness；Second bondline thickness accounts for the 10-15% of overall thickness；
The outer layer thickness accounts for the 15-20% of overall thickness.
Preferably, the preservative film with a thickness of 25 μm -100 μm.
Preferably, the hot sealing layer is by linear low density polyethylene, low density polyethylene (LDPE) or metallocene low density polyethylene (LDPE)
At least one of mixed with nano-functional material.
Preferably, the nylon of the barrier layer is at least one of homopolymerization nylon or copolymer nylon.
Preferably, the polyvinyl resin of the outer layer is that linear low density polyethylene, low density polyethylene (LDPE) or metallocene are low
At least one of density polyethylene.
Preferably, the density of the linear low density polyethylene is 0.918g/cm3~0.935g/cm3；The low-density is poly-
The density of ethylene is 0.920g/cm3~0.950g/cm3；The density of the metallocene low density polyethylene (LDPE) is 0.918g/cm3~
0.942g/cm3。
By adopting the above technical scheme, using the functionality of the barrier property of nylon and nano material, the food for being made novel is protected
Fresh film, the material is degradable, and the ethylene discharged when can be by fruit vegetables storing resolves into CO2And H2O reduces ethylene in packaging
Content fresh keeping time under room temperature can be made to extend 3-5 days to achieve the effect that fresh-keeping.The product can improve existing
Transportation Model, realization remove cold chain transportation, reduce corresponding cost；The product has the left and right of fungus-resistant simultaneously, inhibits benzene
The activity of alanine aminonialyase, polyphenol oxidase, peroxidase；Being tangled by the stabilization that nano material quantum tunneling generates makes
Fruits and vegetables in a dormant state, delay respiration, so that freshness and mouthfeel be made to get a promotion.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, 1- hot sealing layer, the first adhesive layer of 2-, 3- barrier layer, the second adhesive layer of 4-, 5- outer layer.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
Embodiment 1
As shown in Figure 1, a kind of nano material preservative film, the preservative film is followed successively by hot sealing layer, the first bonding from the inside to the outside
Layer, barrier layer, the second adhesive layer and outer layer five-layer structure；
The hot sealing layer is the mixture of polyvinyl resin and nano-functional material；The nano-functional material can be selected
But it is not limited to the nanometer grade powder of the polymer such as polyethylene and polyamide；
The barrier layer is nylon；
The outer layer is polyvinyl resin.
Preferably, the hot sealing layer thickness accounts for the 20-35% of overall thickness；First bondline thickness accounts for overall thickness
15-20%；The barrier layer thickness accounts for the 15-30% of overall thickness；Second bondline thickness accounts for the 10-15% of overall thickness；
The outer layer thickness accounts for the 15-20% of overall thickness.
Preferably, the preservative film with a thickness of 25 μm -100 μm.
Preferably, the hot sealing layer is by linear low density polyethylene, low density polyethylene (LDPE) or metallocene low density polyethylene (LDPE)
At least one of mixed with nano-functional material, polyethylene and poly- can be selected but be not limited to the nano-functional material
