    Peel testing is used to assess bond quality and is a simple way of determining the adhesion strength of a material, especially in the case of a thin film deposited on a substrate.

    By measuring the tension characteristics between the adhesive and the adherend surface, it is extremely useful in assessing the effects of processes (e.g. surface treatment) or real-life performance (e.g. environmental exposure).

    There are various methods of peel testing but they all require at least one flexible adherend to be held in a tensile grip and separated from the other surface. The tensile force-extension values are continuously recorded to obtain precise data for calculating peel values. The main differences between the methods are the angles of peel and whether the peel angle remains constant during the test.

    In the below video, a 135 degree peel test is carried out on a sample of medical packaging to ensure maximum seal with minimum peel. A custom-designed vacuum fixture attached to a MultiTest-i PC-controlled force tester holds the sample firmly so that repeatable results are achieved when the lid is peeled off at a constant speed of 500 mm/min.

    Ensuring the packaging container does not deform when the seal is peeled open is essential for accurate, repeatable results. This flexible medical device packaging is held rigid by vacuum suction to prohibit its movement.

    Mecmesin OmniTest machine demo by the Duchess of Sussex at University of Chichester Tech Park opening

    The Duke and Duchess of Sussex officially opened the University of Chichester’s new Engineering and Digital Technology Park on 3rd October 2018. Part of the tour of the £35million development, based at the Bognor Regis campus, was a visit to the Department of Engineering and Design. The laboratory features several Mecmesin force measurement machines, notably a 50 kN OmniTest Universal Testing Machine (UTM); a state-of-the-art software-controlled materials testing system.

    Methods of force and torque testing for food packaging quality

    Packaging solutions for food are incredibly diverse; in all aspects of physical design, mechanical function and aesthetic appeal. Their purpose is more straightforward: be safe, secure, yet easy to open, close or reliably re-seal; dispense cleanly and efficiently; minimise loss and waste; maximise shelf life; be cost-effective to manufacture and ultimately recycle or dispose of. Add to that, the consumer desire for attractive and innovative new designs, and the straightforward ultimate purpose can become quite involved in terms of meeting each individual challenge.

    Mecmesin white paper: Force testing in medical tubing

    Plastic medical tubing is central to the provision of effective health care in the 21st century. It is essential for the delivery of blood, nutrients and gases to the patient, and for the execution of minimally invasive surgical procedures such as cardiac angioplasty, which have proliferated widely over recent years. This article examines four force testing procedures for plastic medical tubing and explores the benefits and methodological considerations of each.

    Universal testing machine range (0.5 - 5 kN)

    Mecmesin offers a wide range of universal testing machines (UTM) for tension and compression testing. At the top end, our MultiTest-i systems are driven by the powerful Emperor™ control and analysis software on a separate PC, while our production-level testers in the MultiTest-xt series offer touch-screen ease of use and rapid processing. All of these systems give fully programmed control and accurate, repeatable testing, with test libraries for instant recall.
