BOPP Tape Shear Tester

BOPP Tapes are generally used as “Packing Tapes” to close the flaps of Corrugated Cartons.

The carton flaps have a spring-tendency. i.e. they try to open up.

If the quality (adhesive’s power to hold the flaps under shear stress) is not good, your cartons will reach their

destination in open condition and this can lead to product pilferage, contamination, etc.

The BOPP Tape Shear Tester is an equipment to determine the resistance to shear of tape under constant load. It is

measured in terms time in minutes for the tape to get disengaged from the holding surface under specified test load.

It consists of a single or multi-station rack or jig to

hold the test panel with the sample. The specified

weights are then hung on the sample.

Digital Timers are then activated to start counting.

The platform below the hanging weights is fitted

with actuators. As soon as the tape fails and the

weight falls on the platform, the Timers freeze the

data.

The user can come back to the machine at

anytime and record this reading.

The machine doesnot need external power supply

and the electronic timers have an LCD display (low

power consumption) and an inbuilt battery (with a

rated life span of 7-8 years). Hence you don’t have

to worry about power failures or keeping the

power ON if the test continues beyond office

hours.

Triple Station Model

Significance of test to consumers and manufactures Consumers - The quality of tape can be judged by the shear holding power of the tape. It is no more a guesswork but

a quantifiable and scientific means of measuring performance characteristics. You can know whether you are getting

the worth of money spent and assure that the packed products reach their destination intact. You can compare

between 2 suppliers to see whose material will perform better.

Manufacturers - By knowing the shear holding power of tape, you can improve over the present performance by

improved formulation adhesive and optimize the cost versus quality.
