The BOPP Tape Shear Tester determines the resistance to shear of packaging tapes under a constant load. It consists of a rack to hold tape samples and weights that are hung from the samples. Digital timers start when the test begins and stop when a weight falls, recording the time taken for the tape to fail under the load. The tester provides a quantifiable measure of tape quality, allowing consumers to ensure tape performance and manufacturers to improve tape adhesives.

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.

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.
