In embodiment, using PE).The preparation method of such sandwich diaphragm is：Before compound, PET inner surfaces printing trade mark or
Symbol word marking, it is then, first that the Buddhist nun gram paper and bottom of middle layer is compound, then the PET in Buddhist nun gram paper surface recombination, form PET-
Buddhist nun gram paper-PE or CPP composite membrane, obtains sandwich diaphragm after curing.
Another type is：Trilaminate material is followed successively by Buddhist nun gram paper, PET and PE or CPP (in this implementation in sandwich diaphragm
In example, using PE).The preparation method of such sandwich diaphragm is：Before compound, PET inner surfaces printing trade mark or word
Mark, it is then, first that the PET and bottom is compound, then the Buddhist nun gram paper on pet sheet face is compound, form Buddhist nun gram paper-PET-PE
Or CPP composite membranes, sandwich diaphragm is obtained after curing.
The thickness of PE layers in above two mode is 25 μm, it is of course also possible to more than 25 μm；The thickness of layer is 12
μm or 16 μm, and the Buddhist nun gram paper is a PET plain weave non-woven membranes, and preparation method is：By PET particles through high-temperature digestion,
By high-pressure spray gun, elongated silk is sprayed at row's nozzle, then, is fallen on the conveyer belt of uniform motion, entered back into oil and add
Heat and temperature are 350 DEG C of a diameter of 600mm, and on two braking clubs of long 3.3m, swaging is obtained into film by two braking clubs
Plain weave non-woven membrane.In the present embodiment, the specification of quality of the Buddhist nun gram paper is 40g/m2, air penetrability >=400ml/kpa.
In addition, PET, PE or CPP in the medicine bag packaging material of above-mentioned first way；In the medicine bag packaging material of two ways
Bis- layers of composite membrane of PET/PE or CPP are both needed to carry out drilling processing, drilling can be a drilling according to gas permeability requirements before compound
Or secondary drilling.The gas permeability variation range of finally formed medicine bag packaging material is 40~1000ml/KPa, for different fresh-keeping envelopes
Product selection is deposited, is such as packed for meat fish preservative, usually requires that gas permeability >=400ml/kpa of packaging material, common product
It is required that the gas permeability ＜ 400ml/kpa of packaging material.
Below with two kinds of products of 7#-1 and 7#-2 that the embodiment of the present invention is prepared to traditional medicine bag packaging material and this
Two kinds of invention " Buddhist nun gram composite membrane " carries out gas permeability performance to be influenced to test by medicament moisture content, storage requirement, manner of packing etc., is passed through
Experiment is tested and is placed on above gas permeability >=400ml/kpa situations of packaging material (because such case is the problem of determining that is situated between to illustrate its quality
It is crucial), result of the test is as follows：
Two kinds of products of 7#-1 and 7#-2 that the embodiment of the present invention is prepared are packed with traditional medicine bag packaging material,
Its gas permeability is as shown in table 2 below with medicament (low-temperature deoxidant) moisture content, storage number of days variation：
Table 2：The gas permeability of traditional medicine bag packaging material is with medicament moisture content, storage number of days delta data
As shown in Table 2：After the medicament of traditional medicine bag packaging material dress different in moisture, packaging material gas permeability have it is different degrees of under
Drop, moisture is higher, and storage time is longer, and gas permeability declines more.When medicament moisture is 22%, 1 month packaging material of storage is breathed freely
Property 170ml/kpa even fallen to by 900ml/kpa.If it follows that fill high-moisture oxygen scavenger, storage with traditional packaging material
After a period of time, the performance of medicament oxygen absorption performance will be seriously affected.
It can thus be appreciated that there are following defects for traditional packaging material：
(1) itself is airtight, pricks hole by punching machine to control gas permeability during production, stability of breathing freely is poor, difficult to control, i.e.,
Make continuously to prick hole twice, gas permeability is still uneven, and some positions are 250~500ml/kpa；Some positions are 600~1000ml/
kpa；
(2) packaging material intensity declines after pricking hole, easily tears broken bag, easily leaks powder, and meeting contaminated food products and medicine bag are not defended
It is raw；
(3) existing packaging material gas permeability influences notable with medicament moisture content, storage number of days, is improved with medicament moisture, storage period prolongs
Long gas permeability can decline, and product oxygen absorption rate and efficiency is caused to reduce.
Therefore, table 2 is statistics indicate that traditional packaging material gas permeability cannot meet the fresh-keeping requirement of meat fish.
The medicine bag packaging material (PET/ Buddhist nun gram paper/PE) of itself ventilative fresh-retaining sealing agent of the present invention, low-temperature deoxidant
Gas permeability with medicament moisture content, storage number of days delta data it is as shown in table 3.
Table 3：The gas permeability of the medicine bag packaging material of low-temperature deoxidant of the present invention is with medicament moisture content, storage number of days variation number
According to
In addition, it is packed into low-temperature deoxidant described herein in traditional medicine bag packaging material and medicine bag packaging material of the present invention
Oxygen absorption rate detection be compared as follows shown in table 4.
Table 4：Oxygen scavenger oxygen absorption rate in traditional medicine bag packaging material and medicine bag packaging material of the present invention compares data
As shown in table 4：Packaging material gas permeability is substantially reduced during traditional medicine bag packaging material packaging pair material medicament, leads to product oxygen uptake
Speed also significantly slows down.Medicine bag packaging material shelf characteric of the present invention is stablized, and packs the medicament of different in moisture, stores one month
After detect：Gas permeability does not change, therefore oxygen absorption rate is faster than traditional medicine bag packaging material during packaging pair material medicament, with tradition
Medicine bag packaging material compares with substantial advance.
And the medicine bag packaging material that medicine bag packaging material used in table 4 is PET/ Buddhist nun gram paper/PE structures, since Buddhist nun gram paper is in centre,
Its gas permeability is bigger by compound influence, causes different parts gas permeability uneven, there is 150~500ml/kpa, also have 400~
850ml/kpa causes the oxygen scavenger oxygen absorption rate difference that different parts are packed more apparent.
To solve the above-mentioned problems, the technological means that the present invention takes is, using the medicine bag packaging material of another structure.I.e. by Buddhist nun
Gram paper is exchanged with pet layer position；PET/PE is compound rear by gas permeability requirements drilling, Buddhist nun gram on multiple is then done in pet sheet face again
Paper forms Buddhist nun gram paper/PET/PE composite membranes, successfully overcomes gas permeability problem of non-uniform, and can reach highly-breathable (no
Less than 400ml/kpa) requirement without leaking powder.
The gas permeability of the Buddhist nun gram paper/PET/PE composite membranes is as shown in table 5 with medicament moisture content storage number of days delta data：
Table 5：The gas permeability of Buddhist nun gram paper/PET/PE composite membranes of the present invention stores number of days delta data with medicament moisture content
