Embodiment
For the ease of understand the present invention, the present invention will be described more fully below, and give the present invention compared with
Good embodiment.But the present invention can realize in many different forms, however it is not limited to embodiment described herein.Phase
Instead, there is provided the purpose of these embodiments is to make the understanding more thorough and comprehensive to the disclosure.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The implication that technical staff is generally understood that is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein "and/or" includes one or more phases
The arbitrary and all combination of the Listed Items of pass.
The preservative film of one embodiment includes basement membrane, ethylene absorption film and the barrier film being cascading.Ethene
Adsorbent thin film is the PET resin film containing ethylene absorbent.Barrier film is the PET resin film containing montmorillonite.
Wherein, PET resin is polyethylene terephthalate.
Above-mentioned preservative film has trilamellar membrane structure, has preferable film forming using PET resin film, respectively in PET trees
Ethylene absorbent is added in membrane of lipoprotein and obtains ethylene absorption film and barrier film containing montmorillonite.In use, preservative film
Oxygen, moisture and the carbon dioxide that barrier film plays a part of outside suppression outwardly enter in preservative film.Fruits and vegetables in preservative film
The ethene of itself release can be absorbed by ethylene absorbent in ethylene absorption film, so that being in low ethylene concentration in preservative film
State, avoid in preservative film the problem of ethene accumulation causes fruits and vegetables accelerated ageing, fresh keeping time is long, fresh-keeping effect so as to reach
The good purpose of fruit.
When the preservative film is used for packaging material, when packing the products such as fruits and vegetables, fruits and vegetables need not carry out any anticorrosive mildewproof in itself
Sterilization fresh-keeping processing, clean fruits and vegetables need to be only placed in the packaging product such as preservative film, by packing the fresh-keeping work(of product in itself
Can, have the function that thing is fresh-keeping to placing in packaging product, effectively extend freshness of the fruits and vegetables in storage is transported, have
Beneficial to fruits and vegetables transportation and packing, enterprise widelys popularize, and market application foreground is wide.
In one of the embodiments, meter includes 50~60 parts of PET resin, ethene in parts by weight in ethylene absorption film
5~8 parts of 10~20 parts of absorbent and plasticizer.Wherein, PET resin is poly terephthalic acid resinoid.
Further, plasticizer is phthalic acid ester or glycerine.Preferably, plasticizer is glycerine.
Further, ethylene absorbent is the molecular sieve for being loaded with active component or the resin for being loaded with active component.Pass
The preservative film of system can not be effectively reduced the ethylene concentration around fruits and vegetables, and in order to ensure being effectively isolated often with external environment
Gas permeability is very low, causes ethylene concentration to gradually step up, and accelerates the rotten speed of fruits and vegetables, have impact on fresh-keeping effect, shortens guarantor
Fresh duration.And the preservative film of this patent is by setting ethylene absorption layer, and ethylene absorbent uses the structure of active component load,
Specific surface area of the active component on molecular sieve or resin is effectively improved, so as to improve its ethylene absorption efficiency, therefore fruits and vegetables
Because ethene caused by respiration can effectively be absorbed into ethylene absorption layer by ethylene absorbent, so as to maintain in preservative film
Low ethylene levels.
Further, the resin for being loaded with active component is the spherical cross-linked polystyrene resin for being loaded with active component.
Further, active component is in potassium permanganate, silver chlorate, aluminium chloride, yittrium oxide and methyl cyclopropene
It is at least one.Wherein potassium permanganate can promote ethylene decomposition with ethylene reaction.Silver chlorate, aluminium chloride and yittrium oxide can not only
Preferably ethylene adsorption is reached, and the decomposition of ethene can be promoted when being acted on potassium permanganate simultaneously.And methyl cyclopropene energy
It is enough to be combined during fruits and vegetables cure with ethylene receptor, and then the synthesis of ethene processed.It is therefore preferred that active component includes
Potassium permanganate, silver chlorate, aluminium chloride, yittrium oxide and methyl cyclopropene.It is highly preferred that counted in parts by weight in active component,
Potassium permanganate, silver chlorate, aluminium chloride, yittrium oxide and methyl cyclopropene are respectively 55~65 parts, 20~30 parts, 5~10 parts, 1~3
Part and 1~3 part.
In one of the embodiments, meter includes 55~65 parts of PET resin, montmorillonite 8 in parts by weight in barrier film
~12 parts and 5~10 parts of plasticizer.It is so class montmorillonite filled in PET resin so that the barrier film of formation is finer and close, such as
This oxygen, moisture and carbon dioxide for playing a part of outside suppression enter in preservative film.Further, plasticizer is adjacent benzene two
Formic acid esters or glycerine.Preferably, plasticizer is glycerine.
Further, being counted in parts by weight in barrier film also includes 5~8 parts of 5~8 parts of cordierite and kaolin.So
PET resin is jointly added to by montmorillonite, cordierite and kaolin, further improves the compactness of barrier film.
Preferably, montmorillonite, cordierite and kaolinic particle diameter are 2~6 μm.
Because the oil resistivity and air-tightness of PET resin are good, but its price is higher, while has the advantages of printing is preferable,
Therefore it is used as the cladding material of preservative film.Due to pvc material (abbreviation PVC) have to the security of human body it is certain
Influence, therefore basement membrane does not preferably use polyvinyl chloride resin.
Further, basement membrane is preferably PE resin films, PVDC resin films or PP resin films.Wherein, PE resins are thin
Film is polyvinyl resin film, and it is safest that PE resin films, which are used for preservative film,.PVDC resin films are polyvinylidene chloride
Resin film, its performance of keeping humidity is relatively good, longer for preservative film basement membrane, freshness date.PP resin films are that acrylic resin is thin
Film, its high temperature resistant, suitable for micro-wave oven.
It is furthermore preferred that the thickness of basement membrane is 12~22 μm.
The preparation method of the above-mentioned preservative film of one embodiment, comprises the following steps：By basement membrane, ethylene absorption film and resistance
After raw material is mixed and heated extrusion respectively corresponding to film, in the inner chamber, intermediate cavity and the exocoel that respectively enter extrusion screw rod, then
The trilaminate material for extruding inner chamber, intermediate cavity and exocoel by drawing stretching bonds successively, obtains preservative film.
The preparation method of above-mentioned preservative film, technique are simple, it is easy to accomplish.Obtained preservative film has trilamellar membrane structure, profit
There is preferable film forming with PET resin film, add ethylene absorbent in PET resin film respectively and obtained containing montmorillonite
To ethylene absorption film and barrier film.In use, the barrier film of preservative film play outwardly suppress outside oxygen, moisture and
The effect that carbon dioxide enters in preservative film.The ethene that fruits and vegetables itself discharge in preservative film can be inhaled by ethene in ethylene absorption film
Receive agent to absorb, so that being in the state of low ethylene concentration in preservative film, avoiding ethene accumulation in preservative film causes fruits and vegetables
The problem of accelerated ageing, so as to reach the purpose that fresh keeping time is long, fresh-keeping effect is good.
It is specific embodiment below.
