Description
Technical field
The present invention relates to a kind of packaging composite films and preparation method thereof, and in particular to a kind of high resistant with oxygen absorption function
Every intelligent active packing laminated film and preparation method thereof, belong to chemical technology field, belongs to oxygen scavenging packaging technical field, can be used for
Food fresh keeping and product are sealed up for safekeeping.
Background technique
The first oxygen scavenger in China, which comes out, has had updated three generation products with fork-like farm tool used in ancient China:
First generation oxygen scavenger should close male proposition by 1980.10 the applicant " air-independent missile components deoxygenation seals up for safekeeping
Lengthen the life research " it starts, stop to Chinese style oxygen scavenger--504 double absorption agent (ZL88105412.7) invention in 1988, representativeness produces
Product have and should close the first oxygen scavenger in China " 801 " that male leader develops, and main feature has: acidity formula, have oxygen uptake single suction function,
Make medicine bag with the modeling paper for being scalded hole or prick hole processing, that there are shelf characterics is unstable, oxygen uptake ability is relatively low, iron powder needs vacuum activating
The problems such as processing, the Hong Kong of outlet in 1984 stop promoting after the quality accident that entire block is scrapped occurs
Second generation oxygen scavenger should close the male Chinese style double absorption agent of oxygen scavenger--504 invented by the applicant in 1988
It calculates, by 2014, first moisture film oxygen absorbent (ZL201410558108.2) came out and stops, and mainstream product has 504 double absorption agent more than 20
Series of products, main feature have: in, base formulation, double suction more inhale function, with through scald hole or prick hole processing three layers (film/
Paper/polyethylene) oil resistant waterproof composite film makees medicine bag, and it is tired that there are the Special Products recipe determinations such as low-temperature deoxidant, medicinal oxygen scavenger
The problems such as difficult and dust pollution is serious, it is inadaptable with environmental requirement, it is therefore desirable to update to adapt to requirements of the times
Third generation oxygen scavenger by the applicant in 2014 should close it is male invent first moisture film oxygen absorbent (referring to
ZL201410558108.2 it) starts, is currently in initial development phase, mainstream product has Nanjing Tian Hua company to produce
504M, 504My and 504R meat antistaling agent etc., main feature has: in, base formulation, double suction inhale function, ventilative with itself more
Three layers of (film/paper/polyethylene) composite membrane " Buddhist nun gram paper " make medicine bag, meet environmental requirement.
Iron powder in oxygen scavenger after processing, improves oxygen absorption performance and reaction speed, and processing iron powder is inherently a kind of
Oxygen scavenger is suitable for making the oxygen uptake ingredient of ' intelligent active film ', is able to satisfy this Special Products exploitation needs, therefore, moisture film
The appearance of oxygen scavenger is that intelligent active film functionization is laid a good foundation.
Packaging material with fresh-keeping function and it can indicate that the novel package technology whether food goes bad is referred to as " activity packet
Dress " or " intelligent packaging " technology.Functional fresh products are combined into one by active intelligent packaging technology with flexible packing material, shape
At " the active smart membranes " really with preservation, simplifies fresh-keeping packaging intelligence, advantageously reduce packing cost
With fresh-keeping cost；Be conducive to preservation technology to promote and packing technique change；The shelf-life that food can be extended, be conducive to food
Storage and transport；It can be convenient consumer and select safe and secure food, be regarded as the revolution of packaging industry, be current
Fresh-retaining sealing technical research forward position, who swings first accounts for the technology who just occupies initiative and dominant right in fresh-retaining sealing industry, accounts for
There is the market share of over ten billion more than one hundred billion, therefore the development for being engaged in active intelligent packaging technology has huge social effect
Economic significance.
Nineteen ninety is released for the laboratory Sydney, AUS CSIR O by the developmental research to active packing film first
A kind of photochemistry oxygen absorbing film.The inner wall of this film is coated with particular dye, and oxygen can be absorbed after being irradiated by light, is one
The light-operated oxygen scavenging packaging film of kind is automatically stopped deoxygenation reaction without light.Countries in the world are all ground in development " active film " since then
Study carefully, but practical product is seldom so far, reason first is that " active film " traditionally shapes, activity oxygen uptake composition therein accounts for
Film weight is no more than 30%, and the packaging bag oxygen uptake ability being made into this film is relatively low, and when packaged food or article can not inhale
