Description

The method of testing of cigarette wrapping paper Thermal Resistant Surface performance

Technical field

The present invention relates to the stable on heating field tests of wrapping paper, specifically a kind of method of testing of cigarette wrapping paper Thermal Resistant Surface performance.

Background technology

Cigarette packs wrapping paper refers to the paper substrate embellish and pressing product for packing cigarette, and tobacco shred wrapping paper refers to the paper substrate embellish and pressing product for packing some cigarette packs.Tobacco shred and box packaging paper are mainly to protect cigarette in market circulation process, facilitate accumulating, and can represent and beautify cigarette brand, are to produce the indispensable important component part of cigarette.

The initial stage that cigarette wrapping paper produces is mainly to transport and the measure taked for cigarette being protected and facilitate.Through very long evolving development so far, the packaging of various different times, different field, different modes has formed distinctive cultural deposits separately.Cigarette package now not only gathered philosophy, sociology, psychology, linguistics, history but also concentrated expression the knowledge such as religion, custom, even digest Social Cultural Connotation, enrich the development of regional culture, realized the succession of history culture.

Abundant along with tobacco shred and box packaging paper intension, the base material of its use, typography, ink are also more aobvious of a great variety, intricate.But use complicated material, adopt bar and box packaging paper that complicated technology produces in the process of cigarette in packet, while seal with thermal shrinkage to packaging film, there is the risk of generation variable color.Part after variable color and the very obvious inharmonious sense of generation around, can produce considerable influence to cigarette product packaging quality, cause certain negative effect to brand image simultaneously.Still there is no at present a kind of method that can accurately, reasonably measure bar and box packaging paper Thermal Resistant Surface performance.

Summary of the invention

The present invention does not still have a kind of defect that can accurately, reasonably measure bar and box packaging paper Thermal Resistant Surface performance methodology at present in order to make up, and a kind of method of testing of cigarette wrapping paper Thermal Resistant Surface performance is provided.

The present invention is achieved by the following technical solutions: the method for testing of cigarette wrapping paper Thermal Resistant Surface performance, the steps include:

1. get with batch bar wrapping paper or box packaging paper sample several, more than meeting and placing 8h in the environment that YC/T 330 requires, to be checked;

2. in bar wrapping paper to be checked or box packaging paper sample, randomly draw 2, according to the characteristic that uses this Wrapping paper packer, 2 specimen surfaces are divided into heat-sealing region and thermal shrinkage region, and thermotolerance test point is chosen in an each region of specimen surface therein, the thermotolerance test point of choosing contains typographies all in this region, and thermotolerance test point is chosen in another specimen surface relevant position;

3. adopt the aberration of 2 the corresponding thermotolerance test points of sample of colour difference meter mensuration that meet ISO13655 requirement, as △ E ^*ab is less than at 0.50 o'clock, enters next step; As △ E ^*ab is greater than at 0.50 o'clock, adopts the visual method that meets YC/T 330-2009 requirements to compare, and enters next step when no color differnece;

4. will be wherein one cut into pat, each pat comprises one or more thermotolerance test points, a pat only comprises a region, and at the coated two-layer cigarette packaging film in each pat surface;

5. set the temperature of heat sealing machine according to pat region, under 0.18MPa pressure, the packaging film of pat thermotolerance test point top is carried out to the heating test of 1.0s, after heating test finishes, pat is cooled to after room temperature, removes packaging film;

If 6. a is to 3. middle △ E of step ^*ab is less than 0.50 corresponding thermotolerance test point while testing, adopts two kinds of methods tests of colour difference meter and range estimation through heating test and heat the aberration of the thermotolerance test point of testing; Now, meet △ E simultaneously ^*ab is less than 1.0 and range estimation when no color differnece, judges that this thermotolerance test point is heat-resisting, otherwise judges thermo-labile;

If b is to 3. middle △ E of step ^*ab is greater than 0.50 corresponding thermotolerance test point while testing, adopts visual method to test corresponding aberration; Now, while meeting range estimation no color differnece, judge that this thermotolerance test point is heat-resisting, otherwise judge thermo-labile;

If all thermotolerance test points of 7. choosing are all heat-resisting, judge that this batch of bar wrapping paper or box packaging paper thermotolerance are qualified; Otherwise judge defective.

The meet environment that YC/T 330 require of step of the present invention described in is 1.: temperature is 23 ° of C ± 5 ° C, and relative humidity 60% ± 5%, without UV-irradiation; Described YC/T 330, ISO13655, YC/T 330-2009 standards are general knowledge known in this field.

Step 2. in the ownership in heat-sealing region and thermal shrinkage region be to be determined by the type that uses this Wrapping paper packer, step 5. in the heating probe temperature of pat be also to be determined by the type that uses this Wrapping paper packer.

Step 3. in as △ E ^*ab is greater than at 0.50 o'clock, employing meets the visual method of YC/T 330-2009 requirements and compares, while having aberration, resample and carry out visual method comparison, if sampling repeatedly still has aberration, bar wrapping paper or the box packaging paper form and aspect of judging this batch have problem, without adopting method of testing of the present invention.

The step 4. size that cuts of middle pat is to be determined by the model of heat sealing machine.What described cigarette packaging film adopted is the packaging film of actual production.

The present invention compared with prior art, has following beneficial effect:

1, the method is divided into heat-sealing region and thermal shrinkage region by tobacco shred and box packaging paper according to the type of packaging machine, and some to representing the thermotolerance test point of all typographies in the selection of each region, and test result comprehensively, accurately;

2, the course of work of the omnidistance simulation package installation of this method, test result is pressed close to produce actual, practical;

3, the method for the invention is offset paper, art paper, white board, art post paperboard, composite card paper, vacuum aluminizing paperboard for material, technique is that common printed, fresh laser, optical wand are radium-shine, bar and the box packaging paper of intermediate color, the various materials such as gold stamping and typography are all suitable for, and usable range is wide;

4, the method for the invention is simple to operate, and measuring speed is fast;

5, the instrument that the method for the invention is used is simple and easy to get, only needs heat sealing machine and colour difference meter just can realize.
