Testing laboratories are constantly working to improve product quality. Thwing-Albert Instrument Company can help provide a single-source solution for updating and maintaining the testing machines used daily to verify that materials are meeting industry standards including ISO, ASTM, TAPPI and many others

The loop tack test measures the contact tack of an adhesive tape that has been formed into a loop. The fixture meets the requirements for ASTM D6195, FINAT FTM 9 and PSTC 16.   When used with the Vantage NX Universal Tensile Tester, a pair of grips hold the sample and the fixture during the test.  The Vantage NX Tester is paired with MAP4 Materials Testing Software which is configured to meet the industry standard and programs the test based on the method selected.  The sample’s adhesive properties are then displayed as real-time results including peak force to debond from the plate.

The quest for softness of an end user product can be quite subjective. However, when paired with MAP4 software, the Vantage^NX Universal Testing Machine can be used to calculate an objective softness value. Compression/softness results of high loft nonwovens can be evaluated to measure a combination of factors including sample loft, thickness, compressibility and structural softness. The test measures the material from the compression phase all the way through the relaxation phase of the material.

Configurable to Meet Industry Standards Including:    
NWSP 120.6, EDANA 30.4-89, ISO EN 9863-1:2005 and other ASTM, INDA, EDANA ISO, NWST, TAPPI, etc

MAP-4 Materials Testing Software from Thwing-Albert simplifies the analysis of physical properties of materials.

Compatible with Windows Operating Systems, MAP-4 is used to run tests on the Vantage Series of Universal Testing Machines. The software platform is intuitive and offers clean, easy-to-use menus. Real-time graphical results are displayed during testing and can be customized to show a variety of information.

Test methods can be selected from the built-in library of standards to meet ASTM, ISO and other unique materials testing applications. Whether the goal is to measure tensile strength, COF, puncture, pull tests, grab tests, or a number of other applications, MAP-4 can easily be configured to run the test and evaluate the data.

The Thwing-Albert JDC Precision Sample Cutter is widely recognized as the preferred sample preparation tool for tensile testing of thin sheeted materials due to the cutting accuracy.  So, how did the JDC win that reputation?  Lots of attention to detail for the blades and a strict quality control process.

When the JDC cuts test strips, they are an exact width and parallel throughout their entire length. The positive cutting action of the dual blades and precision ground base shear cut both sides of the sample at once assuring a clean, accurate cut every time. The cutting blades are made of high quality tool steel which is stress relieved by cycling between cold and hot temperatures to prevent the blades from warping.  Customers can select from models to cut widths of 1/8 to 3 inch and strip lengths of 10, 12, or 16 inches. 

Blocking is the unwanted adhesion between layers of plastic film.  Results reflect the ability of a material to adhere to itself when pulled apart.  ASTM D3354 specifications are used to program MAP-4 materials testing software to run the blocking test.  The results demonstrate the degree of blocking that exists as a result of factors including film processing, storage, temperature and pressure.

To measure the blocking load of a plastic film by the parallel plate method, the Thwing-Albert Vantage Series Tensile Testers with MAP-4 software can be used to quickly analyze the data collected from the test. 

The method can be summarized:

• Using two plastic blocks the two layers of film are pressed between them
• One layer of film is attached to the upper block and the other layer is attached to the lower block
• The upper and lower block are slowly separated
• The film layers are then pulled apart at a constant speed until separated
• The force to separate the layers of film is recorded in realtime

The Score Quality Test is used for corrugated containers according to TAPPI T829 when attached to the 1270 PCA Score Bend Tester or the EJA Vantage Series Universal Testing Machine you can study the realtive quality of scores for various packaging applicaitons. 

Cuts made to prepare a sample for tensile testing are critical to the accuracy and quality of the results. Preparing a sample without jagged edges or nicks is vital to ensure accurate tensile results. Those imperfections will affect the ability to provide consistent tensile results for the physical properties of the specimen. The way a sample is handled can also have an impact on the tensile test results and should also be handled with care once cut.

Accurate thickness measurements are critical to product quality in many manufacturing applications such as paper, plastic film, nonwovens, and textiles. Testing can optimize the raw materials for production and ultimately reduce costs. So, how do you choose the right type of thickness gauge when there are so many options on the market? To narrow the search, it will be important to consider the material to be tested, the application and the precision required to meet any specific industry standards.
