Description
Technical field
The present invention relates to packaging film fields, and in particular to the packaging film of selective absorption ethylene contains more particularly, to one kind
The plastic packaging film and preparation method of the selective absorption ethylene of diatomite.
Background technique
With the development of economy, improvement of living standard, the dietetic life of people is by past unification mistake simply having adequate food and clothing
Cross diversified auxotype till now.The demand of fruit is increasing, and the requirement to its freshness is also higher and higher.Due to
Fresh fruit picking after continue to breathe, and breathe simultaneously with metabolism, moisture evaporation and ethylene synthesis, promote fruits and vegetables into
One step is mature；This storage condition also makes bacterium be easy to breed, and breeds rapidly, and fruit is caused to rot.Ethylene gas is to plant
The hormone of object growth.Although ethylene can promote plant growth and fruit maturation, it is to cause fruits and vegetables easy
The main reason for rotten.Ethylene induces the aging of fruits and vegetables, reduces its shelf-life, drops its vision and organoleptic quality greatly
It is low.
The method for eliminating ethylene at present, which has, to be added potassium permanganate class oxidant pack, molecular sieve or activated carbon adsorbent is added
Etc. means.The ethylene absorbents such as potassium permanganate can accumulate in packaging bag to avoid ethylene, but potassium permanganate is easily dissolved ring
Moisture in border and cause fruit to be colored, and potassium permanganate is a kind of chemicals, must not contact food.Also there is report in the country
Road is clipped in corrugated case or paper pulp molding package box using molecular sieve or activated carbon as ethene adsorbent, influences whether corrugation
The intensity of carton, ethylene absorption efficiency are relatively low.Therefore, the packaging material of novel ethylene adsorption is studied increasingly by weight
Depending on.
Number of patent application 201710750677.0 discloses a kind of buffering packing film with ethylene absorption function, comprising thin
Membrane body, independent air bubble and ethylene absorption package.It is characterized in that：Film bulk is double-layer structure, and independent air bubble is in film
It is formed in this interlayer body, ethylene absorption package is located in independent air bubble according to certain arrangement mode.The beneficial effect of the invention
Fruit is：Innovative ethene adsorbent is made small package, and pre-buried to be filled in duplicature interlayer, membrane body is using high
Breathable films facilitate ethylene through and by ethylene absorption and wrap up absorption.It is pre-buried by the way of 5 points of arrangements in unit area,
Package distribution can be made regular, more completely absorb ethylene.In addition, independent air bubble in membrane body interlayer on the one hand can be with
Pre-buried absorption package, is on the other hand also beneficial to antidetonation.
Number of patent application 201310071444.X discloses the fruit and vegetable fresh-keeping agent pack and packaging film of a kind of controlled release
Production method belongs to food and postharvest technology of fruits and vegetables field, and potassium sorbate is dissolved in solvent and obtains mixing antistaling agent solution, will be mixed
It closes antistaling agent solution absorption and carries out package encapsulation in the carrier of expanded vermiculite, then with modified polyolefine material, solvent is second
Alcohol, the ethyl alcohol of acetaldehyde or arbitrary proportion, acetaldehyde mixed liquor, the dosage of potassium sorbate are the 0.5 ~ 3% of solvent quality.Modified polyolefin
Hydrocarbon material after being blended with the amorphous substance of 2 ~ 15wt%SBS or 5 ~ 50wt%, is passed through using LDPE, LLDPE, CPP as matrix resin
The film that blow molding or coextrusion are formed, amorphous substance are styrene-ethylene copolymers, styrene-butylene polymer or SEBS
One or more of Deng.The controlled release antistaling agent and its packaging of the invention, can be used for granulated sugar tangerine, grape, strawberry and holy girl
The long acting fresh-keeping of the fruits and vegetables such as fruit.
Number of patent application 201010522442.4 discloses the fruit-preserving green packing material with ethylene adsorption function
And preparation method thereof, belong to packaging material field.Material include 100 ~ 90 mass fraction polyethylene or acrylic resin and 0.5 ~
The al silicate molecular sieve that 10 mass fraction granularities are 5 ~ 100 microns, silica alumina ratio is 5 ~ 100.Preparation method includes preparing silicon first
Then sour aluminum molecular screen will be blow molded into film after al silicate molecular sieve and polyethylene or acrylic resin melt blending.It should
The packaging material ethylene absorption rate of invention reaches 0.25~0.43ml/daym2, 1300~4600ml/ of OTR oxygen transmission rate
day·m2；It can make the shelf life extension 25~125% of banana, weightlessness reduces 50% or more.
Number of patent application 201710903104.7 discloses a kind of green vegetables transport case based on ethylene absorption technology, including watt
Stupefied carton separates cardboard, ethylene absorption packet.Specially：Corrugated case by back side panel, front side board, right end plate, left side plate, flap,
Bottom plate, cover board, manufacturer's connector, tongue are constituted, and material is a kind of stupefied corrugated board of C, and corrugated case uses self-locking bear building-up
Structure, ease of assembly and use.Corrugated case is built-in with ethylene absorption packet, and the ethylene gas caning absorb in corrugated case prevents blueness
Dish turns yellow and nitrite accumulation.Separating cardboard can be separated green vegetables by layer, and separation paperboard surface, which is covered with PE film, can prevent moisture
It is lost, paperboard surface is evenly distributed with venthole, is conducive to the flowing of ethylene gas and is adsorbed.
It can be seen that it is poor to the adsorption effect of ethylene for the packaging material of fruits and vegetables in the prior art, cause fruits and vegetables easily to decline
It is old rotten, and the existing method security that potassium permanganate class oxidant pack is added is poor, and molecular sieve or active carbon adsorption is added
The problems such as means of agent easily influence the mechanical property of packaging material, and then not good enough there are service performance.
Summary of the invention
Effectively to solve above-mentioned technical problem, the invention proposes a kind of plastics of the selective absorption ethylene of containing diatomite
Packaging film and preparation method, can effective ethylene adsorption, be conducive to preserving fruit and vegetable utilizing, and to the Effect on Mechanical Properties of packaging material compared with
Small, service performance is good.
