Mecmesin’s force, materials and torque testing systems offer the following benefits to packaging and packaging material manufacturers around the world.

Can the robustness and reliability of your packaging be easily determined? Can your customers be provided with indisputable evidence of production quality? Is it possible to ensure that your packaging will perform under storage and transportation conditions?

Mecmesin enables packaging materials and products to be manufactured to consistently superior quality.

Can the wall thickness of the PET bottle be reduced and made lightweight with no compromise on its strength? Can the surface roughness of the packaging material be reduced to cut down processing cycle time?

Mecmesin helps manufacturers to decrease material costs and realize lean manufacturing and environmental objectives.

Do customers know the exact force needed to tear a packet, peel a seam, twist open a cap, remove a cork, pierce a foil, or actuate a pump on their packaging product? Does their packaging protect the product but remain easy for the customers to open?

Is it possible to ensure whether the products meet all pertinent national and international criteria, as well as in-house specifications?

Mecmesin’s force, materials and torque testing systems are suitable for testing a broad variety of packaging materials:

A simple tensile test is very useful in determining a wide range of packaging material properties and assessing the dissociation strength of jointed components.

For instance, tensile tests are used to find the strength and performance of heat-sealed or glued seams on foil or plastic packaging. As such, they offer a quantifiable evaluation to demonstrate whether packaging can be easily opened by a user, and they do not tear completely so that the contents do not spill out.

Resistance to top-loading is one of the most important parameters in the design and quality of any container, from drums and PET bottles through to cardboard boxes, bevcans, and food tins.

With Mecmesin’s strong and compact top-load testing systems, both maximum compressive load and container free height can be quantified by just pressing a button. Accurate top-load assessment allows manufacturers to decrease material usage, reduce costs, and fulfill environmental standards, without affecting the compressive strength of the container during the filling, capping and distribution process.

Our investment in the MultiTest 5-xt top-load test unit has paid for itself time and time again. The unit is so easy to use that no outside training was needed at start-up and training new operators was very minimal. This has resulted in no misjudgments from equipment set-up. The displayed graph makes it very easy to understand what is occurring during the test and aids in troubleshooting and correcting issues. The touch screen/computer combination reduces the footprint to less than half the size of our older unit. Overall the unit gives great performance at a very competitive price.

Adhesive or heat-sealed joints and seams must be firmly formed to guarantee that the packed contents are protected and hygienic, but at the same time, the packaging should remain easy for the customer to open. Mecmesin’s peel testing system offers a quick, repeatable, and accurate technique for evaluating the force needed to start and propagate a peel on adhesive bonds and container seals.

Form-fill-seal converting machinery must move, feed, form, stretch, cut, weld, and apply tensile load to raw packaging materials at high speeds.

The surface roughness of the material has a significant effect on the ease with which this may take place and thus the efficiency of the converting process. A valuable parameter for characterizing the surface roughness of the material is the coefficient of friction (COF).

The FPT-H1 is designed for quick and easy testing of static and dynamic coefficients of friction of a variety film and sheet materials.  Test samples are secured to the plane bed and to a sled that is linked to a traversing crosshead driven by a precision ballscrew.   Positioning and drawing of the sled is controlled by Emperor programs, which capture the test data, displaying the graph trace live, throughout the test run.  At the end of each run the data are analysed, providing results for static and/or dynamic coefficients of friction and allowing for sample comparison against quality standards if required.

A bottle cork must form an adequately tight seal to guarantee that the contents are uncontaminated, while at the same time it should also remain easy to open.  The CombiCork Extraction Tester from Mecmesin determines the release twist torque of a champagne/sparkling wine cork or spirit bottle stopper, as well as the extraction pull-out force of a classic still-wine cork.

The “Combi” Cork Extraction Tester is developed in collaboration with and authorized by Oeneo Boucharge, one of the top cork manufacturers in the world, and it enables:

As a responsible supplier we are committed to ensuring safety within our products. The solution provided by Mecmesin means we can monitor the extraction force of our corks to guarantee our customers receive a consistent end product.

In addition, Mecmesin provides a Combi Cork-i testing system, which can simultaneously measure both the extraction force and torque needed to pull and twist a cork from a sparkling wine or spirits bottle.

The delivery of products such as liquid soaps, perfumes etc. relies on the performance of aerosol or pump dispensers.  A simple compression test carried out on aerosols or hand pumps e.g. on liquid soap bottles, to a pre-determined displacement accurately determines the actuation force of spring-operated dispensers.

To conduct the test, the container is positioned underneath the crosshead/loadcell of a motorized compression testing machine and a small compression plate is brought down above the central axis of the pump/aerosol. This is compressed to a preset displacement and the maximum force recorded is the pump/aerosol actuation force.

Ring-pulls are found on food tins, beverage cans, and tennis ball tubes and must have the ability to endure an adequate level of tensile loading to open the pack, without being separated from the lid. The quality and suitability of the ring-pull mechanism can be evaluated with a simple tensile test on a ring pull.

Snap-caps must lock firmly with a positive click on closure, but it should also be easy enough to be opened. Mecmesin’s motorized force testing system enables easy testing of the compressive force needed to click shut a snap-cap as well as the tensile force needed to open it.

A vital process in the production of well-designed and consistently manufactured screw closures is torque measurement. A broad range of torque testing equipment from Mecmesin serves nearly any closure torque testing application, from tamper-evident beverage bottles to child-resistant pharmaceutical containers.

The Tornado Digital Torque Tester from Mecmesin has been developed to measure the two vital torque peaks related to tamper-evident closures. One peak is called the “slip” torque, which is the effort needed to start the movement of the cap, and the other one is the “bridge torque,” which is the smaller, secondary effort needed to break the plastic bridges between the cap and security ring.

When processing screw closures, it is necessary to apply adequate torque to ensure an airtight seal within the lid; however, the torque must not be too much or else it might damage the closure lining. A Mecmesin torque tester positioned at the point of production enables simple in-line checks to be carried out effortlessly. This guarantees that the capping heads constantly apply the right torque levels.

When child-resistant closures (CRCs) are designed, a fine balance between security and accessibility must be achieved. The CRC Tester from Mecmesin can simultaneously measure both compressive force and torque to characterize the “push and twist” action required in opening a CRC. In addition, the CRC Tester may be used to evaluate the reverse ratchet torque of CRC closures.

The success of the introduction of screw cap closures in the wine industry can be attributed to the successful application of the closure itself. In order to determine a good application, you require reliable, accurate and consistent testing equipment. The Mecmesin closure torque testers have fulfilled all the criteria and have given us great confidence in our application of the screw cap closures.

It is possible to place even awkwardly shaped containers easily in the versatile mounting table, and it is a feature of all Mecmesin torque testing equipment. Movable gripping pegs may be simply repositioned to orient the closure above the central axis of the mounting table. Furthermore, Mecmesin can provide custom-engineered gripping accessories including a wide range of cap mandrels.

The Mecmesin Vortex gives us peace of mind that our process is in control on screw cap application. Our production line does half hourly checks for measuring the seal torque and bridge break torque. The Mecmesin Vortex is a great instrument for us.
