The scope of research
Leakeage testing
The test consists in checking the tightness of the closure and the packaging connections by gravity in wide-open packages or by the pressure method at overpressure of air inside the tested package for narrow-bore packages (A <70 mm).
 |
The stand is designed to test the tightness of plastic and narrow-bore plastic packaging at 20 and 30 kPa measuring pressures. Maximum package volume - 300dm3 when tested in water. |
Packages equipped with handles require tests of their resistance to loads specified in the Technical Criteria. The laboratory is equipped with a special stand for testing the strength of the handles and resistance to breaking at a given force in a given time.
 |
The stand is designed for testing the strength of holders in the range up to 5 kN packages with dimensions: width and diameter up to 700 mm, height up to 700 mm |
Impact resistance with free fall
Drops are made from the height required by the Technical Criteria for a given type of packaging. The packaging before the test is air-conditioned in the conditions required for the material from which it is packaged. The laboratory is equipped with special stands for these tests.
 |
CHUTE Designed for making drops in rigid metal, wooden, cardboard and plastic packaging. Maximum height of 4 m fall; the maximum weight of the packed packaging is 300 kg. A concrete collision surface or a steel plate. |
 |
RACHET TABLE It is designed to make drops of elastic packaging (bags) from a height of 0.3; 0.6; 0.9 and 1.2 m., Weighing up to 60 kg |
 |
DROP It is designed to make drops in semi-rigid and flexible packaging as well as small rigid packaging. The maximum height of the drop is 1.8 m. The maximum weight of the package with a content of 60 kg. A concrete crash surface or a steel plate |
Resistance to static pressure
This test reflects the exposures associated with transport and storage of packaging with packed goods under load during stacking. The weight of the load should be equal to the pressure force acting on the packaging set at the bottom of the pile at a height of at least 2.5 m. This test is carried out at special stands.
 |
PRESS FOR STATIC TESTS The stand is designed to test the resistance to pressure when stacking packages with maximum dimensions of 800x700x1200 mm and the required pressure within the limits of 40 to 600 kg |
 |
PRESS The stand is designed for testing packaging with maximum dimensions of 2,00x2,00x2,50m; maximum pressure - 100 kN and packaging with maximum dimensions of 0.6x0.6x2.0m; maximum pressure - 10.0 kN The stand is designed to test the resistance to pressure when stacking plastic packaging with maximum dimensions 800x600x1200 mm and the required pressure within 20 to 600 kg at elevated temperatures up to 45oC |
 |
 |
Resistance to horizontal impact on the ramp This test mirrors the exposure associated with railway and car transport of cardboard packaging with packed goods. This test is performed on a slipway with a ramp. The stand is designed for testing transport packaging and pallet load units with a maximum gross weight of 400 kg. Maximum speed at the moment of impact up to 3.85 m / s. Resistance to vibrations with constant low frequency.

 |
Testing the stability of shape and dimensions under the influence of elevated temperature The chamber is used for air conditioning of packaging in the programmed temperature range from -40 to + 60oC and humidity from 10 to 95% |
The laboratory conducts cardboard tests to determine the mechanical properties of cardboard used for packaging.
We can specify such cardboard parameters as:
- Total weight and basis weight of component layers
- Resistance to bursting
- Resistance of corrugated cardboard to flat crush (FCT)
- Column crush resistance (ECT)
These tests are carried out using modern research equipment.
 Scales with the required range and weighing accuracy used to determine basis weights. |
 Lorentzen & Wettre device for testing cardboard resistance for absolute rupture in the range from 250 kPa to 6000 kPa |
 Lorentzen & Wettre press for flat crumpled cardboard (FCT) test of surface corrugated cardboard samples 100; 50; 32 cm2 and column crush (ECT) of type A samples with dimensions of 25x100 mm in the pressure range up to 5 kN. |
