Heat seal testers
The heat seal testers GHS-03, HST-H3, HSTH6, HTT-L1 and PSST-100 determine the optimal sealing parameters such as temperature, time and pressure for the different film materials.
The heat seal testers GHS-03 allows the simultaneous testing of 5 samples independently. The hot tack and seal property tester HTT-L1 can additionally measure the peel force, tension and shear force of tapes. The PSST-100 is a portable seal strength tester.
The models RSY-R2 and FST-02 are suitable for determining the heat shrinkage properties of films made of polyethylene, ethylenes and copolymers and mixtures thereof. The shrinkage, contraction force and the shrinkage ratio of shrink films under specified test conditions can be determined in this way. With RSY-R2 the films are tested in an oil bath without clamping in the apparatus. In the apparatus FST-02 up to 3 samples can be simultaneously and independently clamped and tested each other.
In the area of the leak tests, we offer three different leak testing devices: MFY-01, LSSD-01 and RGT-01.
Packaging materials with vulnerabilities as sealing seams or products are subjected to a pressure difference, are tested to their tightness qualities, failure and durability as well as creep characteristics and compression resistance. The devices can be used for a variety of packaging shapes. The model MFY-01 can test the tightness of seals of different packages through the differential pressure method in water and thus detect leakage and deformations in a vacuum.
The sealing quality of bottles, tubes, caps and other packaging is checked by the device LSSD-01. With the over pressure method, the creep and failure limit and the compression resistance can be measured quantitatively.
The device RGT-01 is the only product on the market, which can perform a quantitative analysis of the residual oxygen in vacuum packaging. The quantitative seal behavior of the packaging can be checked by the differential pressure method and the liquid analysis technique.
Adhesive and Tape Tester
The devices CZY-G and CZY-6S test the adhesion and adhesive properties of test samples as pressure-sensitive tape, plasters, adhesive labels and protective films. While the Model CZY-G works with the Rolling Ball method, six samples can be tested simultaneously under the influence weight with CZY-6S. This model is controlled by a microcomputer. Other testing equipment like peel adhesive tapes testers may to be found in the catalog of mechanical test instruments.
These and other test equipment will be shown at the FachPack 2015 in Nuremberg.
