core tip: This paper uses Labthink Languang XLW (EC) intelligent electronic tensile testing machine to test the adhesion of ribbon ink layer, and details the basic information process, test principle and equipment parameters of horizontal tensile testing machine, Enterprises can refer to it when verifying the adhesion fastness of ink layer

[China Packaging News] ribbon is a kind of printing consumables that we are familiar with. Many industries such as food, medicine and daily chemical use it to print the production date or shelf life, which does not prevent the ink layer from falling off and affecting sales. The adhesion ability of the ink layer of ribbon should be strictly monitored. This paper uses Labthink blue XLW (e because this experiment only needs to convert one channel C) intelligent electronic tensile testing machine to test the adhesion of ribbon ink layer, and details the test process, test principle, equipment parameters, etc., which can be used as a reference for enterprises when verifying the adhesion fastness of ink layer

1. Current situation

the composition of the ribbon is very simple, which is made of nylon yarn as raw material after soaking and dyeing with ink. Its working principle is that the use of needle type also needs to pay close attention to the changes and impacts of national policies from environmental protection and other aspects. The dot matrix stylus in the printer head or the letter stylus in the English typewriter will impact the printing ribbon and produce a printing effect on the printing paper. The application field has developed from the original single printed manuscript to arrival tickets, tickets, labels, invoices, cards and other aspects. Its substrate has developed from a single paper to plastics, fibers, composites, fabrics, calendering materials, etc. Ribbons are divided into four categories, which are applicable to printing of different materials

type I fr wax based heat transfer ribbon: suitable for paper, leather and other materials; Temperature range: 90 ~ 120 ℃; Features: clear printing, strong adhesion, high cost performance, but the printed film characters are easy to be hollow

type II FC2 resin based heat transfer ribbon: suitable for paper, polyethylene film (PE), polyvinyl chloride film (PVC) and other materials; Temperature range: 110 ~ 160 ℃; Features: clear printing, strong adhesion, but with slight adhesive tape

type III FC3 resin based heat transfer ribbon: suitable for aluminum foil (AL), polypropylene film (PP), polyester film (PET), polyethylene film (PE), polyvinyl chloride film (PVC) and other materials. Temperature range: 110 ~ 160 ℃; Features: the performance is the same as scf900, but the adhesion is slightly worse than scf900 ribbon

type IV scf900 resin based heat transfer ribbon: suitable for aluminum foil (AL), polypropylene film (PP), polyester film (PET), polyethylene film (PE), polyvinyl chloride film (PVC) and other materials. Temperature range: 120 ~ 180 ℃; Advantages: excellent abrasion resistance, clear printing, cooking resistance, and freezing at minus 20 ℃

2. Test standard

this paper uses GB 8808 "soft composite plastic material peel test method" to test the adhesion ability of the ink layer inside the ribbon

3. Test sample

two color bands of 25 mm wide and 30

mm wide provided by a factory

4. Test equipment

XLW (EC) intelligent electronic tensile testing machine independently developed and designed by Jinan Languang Electromechanical Technology Co., Ltd

Figure 2 XLW (EC) intelligent electronic tensile testing machine

4.1 test principle

the sample is clamped between the two collets of the fixture, and the two collets move relative to each other. Through the force sensor located on the moving collet and the built-in displacement sensor of the machine, the force value changes and displacement changes during the test process are collected, so as to calculate the adhesion, peel strength, tension, deformation rate and other performance indicators of the sample

4.2 scope of application

this equipment is specially used for the adhesion, stripping, stripping force, stretching, deformation, tearing, heat sealing, bonding, puncture force, opening force of products such as plastic film, composite material, soft packaging material, plastic hose, adhesive, adhesive tape, self-adhesive, medical patch, release paper, protective film, combination cover, metal foil, diaphragm, backplane material, non-woven fabric, rubber, paper, etc Test the performance of low-speed unwinding force, such as the tearing force, puncture/pulling force of oral liquid cap, puncture force of infusion bag cap, puncture/pulling force of soft rubber bottle stopper, etc

this equipment meets a number of national and international standards, such as GB 8808, gb/t

l support lystemtm laboratory data sharing system to realize unified management of test data

5. During the test, the size is 24 mm × Five 100 mm samples of two kinds of ribbons

take the tape with the same width (the force value is about 3 N) and glue the samples together with ygj-02 adhesive tape roller with standard load, rolling speed and rolling times

clamp the tape and ribbon with the upper and lower clamps of the equipment respectively, so that the long axis direction of the sample coincides with the center line of the two clamps

set the sample name, sample thickness, test temperature, test humidity and other parameters

click the test start option, the test starts, and the equipment automatically tests the force value in the sample stripping process, and reports the final test results

6. Test results

the test results of two ribbon samples are as follows: the stripping force of 30 mm ribbon is 0.037 n, resulting in a long cycle of product technology update, 0.034 n, 0.040

n, 2.917 n, 2.878 n, 2.808

7. Conclusion

from the above test results, the stripping force of 25 mm ribbon is greater than that of 30 mm ribbon, indicating that the ink layer adhesion ability of 25mm ribbon is higher than that of 30 mm ribbon, and 25 mm ribbon is not easy to cause the phenomenon of film falling off compared with 30 mm ribbon.
