Description
Technical field
The present invention relates to packaging and label technique field, more particularly to one kind can wash transparent thermal contraction type beer bottle label and
It washes mark technique.
Background technology
While the development of modern packaging technology is swift and violent, higher requirement is proposed to cost efficiency environmental protection, in beer packing
Field, to reducing energy consumption, increase production efficiency, lifting label texture, preventing the requirements such as disposal of pollutants and become increasingly conspicuous.To lift beer
The brand image of wine, Brewage business is while itself quality is lifted for many years, the also innovation of moment emphasis beer label.
With extensive use of the clear label in food, cosmetic field can be washed, also cause the pass of some Brewages business
Note.StienbeisPPL companies have developed with PET shrink films and PVC shrink films etc. as plane materiel in 1999, acrylate pressure
Quick glue washes clear label for adhesive；The Thermo Wash that Spear companies developed in 2005 can wash clear label skill
Art, using being coated under pressure-sensitive adhesive layer or the technology of printed coating reaches ideal effect；South Korea east is made within 2007
Wine company uses the transparent washable label that CCL labels company newly releases, and the label uses intaglio printing.Transparent do not done although can wash
Glue label has many unique advantages, but the cleaning process of these labels has still continued to use tradition and washed beacon course sequence：In 85 DEG C of acid
A period of time is soaked in liquid or alkali lye, bottle mark can be just washed away, so not only aggravate machine loss, cleaning agent is also add and sets
Standby scale removal is paid wages.
Patent No. CN201610701800 also discloses a kind of washing and removes pressure-sensitive adhesive agent preparation method and label, passes through
Stick on the container of reusable edible, label is come off by 65 ~ 90 DEG C of 1 ~ 2min of hot-water soak, reach and wash heading,
This technique is low due to long soaking time, producing line efficiency.

National standard method is tested, and can wash the method that shrinkage uses hot-water soak；Cold resistance uses refrigerator freezing method.Main test
As a result such as table 2：
Embodiment 3
It is prepared by PETG film layers：
1）According to the label invention requirement that shrinkage factor is big, contraction speed is fast in the hot water, label transparency is high, using Isosorbide-5-Nitrae-hexamethylene
The amorphous transparent PETG copolyesters that one or more in alkane dimethanol, propane diols, 1,6-HD, pentaerythrite are modified is cut
Piece, obtained PETG copolyester sections inherent viscosity are 0.83dl/g, and glass transition temperature is 81 DEG C, and melting range is 160 ~ 190
℃；
2）By step 1）PETG copolyester sections and 0.1 ~ 1.0% anti-reflection master batch be blended, and extruded machine melting extrusion, lead to
Die head/cold founding piece is crossed, it is then under external force, longitudinal 3.5 times, horizontal 5.3 times in being carried out in 80 ~ 130 DEG C of temperature ranges
Stretching, cooling, winding, the first temperature controlled region of extruder temperature is 190 DEG C, the second temperature controlled region temperature is 230 DEG C, the 3rd temperature controlled region
Temperature is 240 DEG C, the 4th temperature controlled region temperature is 240 DEG C, the 5th temperature controlled region temperature is 230 DEG C, the 6th temperature controlled region temperature is 230
DEG C, draft temperature is 98 DEG C；
3）Further, step 2）The middle transparent heat-shrinkable film thickness 41um of gained PETG, 5s horizontal stroke is soaked in 90 DEG C of hot water
It is 82% to shrinkage factor, longitudinal contraction rate is 35%, mist degree 2.9%；
4）By step 3）The one sides of middle gained PETG shrink films carries out intaglio printing, and printing speed is 110 ~ 130m/min, drying tunnel
Temperature is 50 ~ 80 DEG C, is finally wound stand-by.
The preparation of pressure-sensitive adhesive oxidant layer：
1）Bonding force is more than according to label convergent force, and the volatilization of glue-line environmental protection VOC free, water-tolerant, the hair without cull during stripping
Bright requirement, using self-crossing emulsion type water soluble acrylic acid ester pressure-sensitive, pressure-sensitive adhesive agent rotary viscosity is 4000 mpas, Gu
Content is 56%, latex particle size 350nm.
2）By step 1）Described in self-crossing emulsion type water soluble acrylic acid ester pressure-sensitive, the coated technique on coating machine
Uniformly it is applied on release layer, and the dry solidification at 90 ~ 150 DEG C, on-line cooling, emulsion acrylic is formed in release layer surface
Ester pressure-sensitive adhensive layer, the first temperature controlled region of drying channel of coating machine temperature is 60 ~ 90 DEG C, the second temperature controlled region temperature is 90 ~ 125 DEG C,
Three temperature controlled region temperature are 125 ~ 150 DEG C, the 4th temperature controlled region temperature is 100 ~ 400 DEG C.
Release layer：
Release layer is the PET film for scribbling organic silicone oil, and off-type force 3gf, remaining then rate is 93%.
Finally, by the multi-procedure of coating machine, the non-printing surface of PETG films and surface are scribbled into emulsion acrylic
The release aspect of ester pressure-sensitive adhensive layer is compound, and winding, produce the present invention washes transparent thermal contraction type beer label.
Wash mark technique：
1）The present invention will be posted can wash the beer bottle of transparent thermal contraction type beer label and be placed in rinse bath, using 90 DEG C of hot water as
Cleansing medium；
2）Body is after 90 DEG C of hot-water soak 4s, and because shrinkage factor is big and contraction speed is fast, the convergent force of label in itself is more than glue
The bonding force of glutinous layer and body, label rapid desufflation is agglomerating and automatically disengages body；
3）Label after separation respectively enters abandoned tender collector with body and bottle disinfection trough sterilizes, and so far, completes bottle and washes
Mark flow.
Test result：
Label of the present invention is labelled through beer producer and tested, transparency, coefficient of friction, tensile strength, shrinkage factor, thickness etc. use
National standard method is tested, and can wash the method that shrinkage uses hot-water soak；Cold resistance uses refrigerator freezing method.Main test
As a result such as table 3：
It can be seen from table 1 to table 3 compared with conventional labels, tag intensity of the present invention is high, and way contracting rate is big, in 90 DEG C of heat
3 ~ 5s is placed in water, label shrinks rapidly and departed from body, effectively improves de- mark efficiency；Bottle after de- mark is clean, nothing
Cull, without vestige, the solvent-free pollution of whole flow process, meet green requirement；In addition, label of the present invention uses high transparency material
Matter, the high-quality sense of label and beer in itself is embodied well, after 0 DEG C of freezing test, label is still as excellent as before.
