Probiotic drink packaging testing

  • Mecmesin

As demand for dietary supplements continues to surge, immune-boosting products, such as prebiotics and probiotics, are amongst the most popular.

Whilst scientific research isn’t yet completely cut-and-dry, consumers are increasingly coming to understand the connection between probiotics and immune health. Probiotics offer a natural solution to support the body’s own natural defence system by helping to ward off diarrhoea, irritable bowel syndrome, eczema, yeast and urinary tract infections.

The classic Greek yoghurt, packed full of those live microorganisms that are supposed to be good for your body, is now accompanied in the supermarket chillers by an ever-expanding range of probiotic drinks. Kombucha, a sweetened tea with a symbiotic culture of bacteria and yeasts, sits alongside fermented dairy probiotics like kefirs, available as smoothies and as sparkling bacteria-rich mineral waters.

Getting these liquid probiotic products noticed by the consumer relies on eye-catching innovative packaging which must be easy-to-open and reseal whilst remaining economic to use for the beverage producer.

  • Software-controlled tensile test stand
  • Container holding fixture (custom-made to match geometry)
  • Small pinch grip and assisted-pull peel table

Testing the quality of the sealed closure can be cost-effectively performed by using Digital Torque Meters for screw-cap closures, which rely on being correctly torqued to maintain a leak-free container to hold the contents fresh and ready-to-drink.

Peeling off those thermo-sealed aluminium foil neck land seal, often found on dairy-based probiotic drink lids, is the job of the tensile tester. Fixturing to hold the container secure, without deformation is essential to ensure repeatable results. If a constant peel angle is required, then an assisted-pull peel table facilitates this by moving the container horizontally at an equal rate to the vertical displacement of the grip. Choice of grip to avoid tearing the foil is also a consideration.

Mecmesin has worked with a plethora of packaging manufacturers, contract bottling fillers and beverage producers in supplying force and torque testing equipment across the world. Supported by a network of international distributors and service centres, Mecmesin is the ideal choice for quality-control equipment to test the mechanical strength of your packaging.

Cosmetic packaging pull-off test

A bench-top testing system was required to repeatably test the pull-off force on a variety of cosmetic containers. The system needed to allow a relatively high volume of containers to be tested with the minimum level of training required for users. Mecmesin's solution avoided the risk of damaging the loadcell by excessive torque on tightening the collet grip, and the lipstick barrel was first inserted in the grip and then connected to the gauge by a flexible chain-link.

Food packaging made from thermoformed plastics and intended for freezing, requires testing to ensure optimum functionality when closing and sealing the container. The closing effort of the lid is measured by using a motorised force tester controlled by software together with a custom-designed fixture to hold standard-sized ice cream tubs. In addition the ‘top-load’ crush strength of the container itself can also be tested on the same machine to guarantee it is rigid enough to avoid buckling and spillage when the lid is applied.

Mecmesin develops Combi Cork-i Extraction Tester for leading Scottish whisky

To improve the quality and storage of a premium product, the R&D team at a leading Scottish whisky maker needed to optimise the design of their bottle stoppers. They decided that the strength and performance of their reusable stoppers could be ensured by systematic testing of the characteristics of both portions of the stoppers. Working closely with the R&D team, Mecmesin developed the Combi Cork-i Extraction Tester, an innovative multi-function cork extraction testing system that tests both phases of de-corking synchronously.

Greek beauty product manufacturer guarantees production quality by updating to Mecmesin's digital torque testers

A manufacturer of a wide range of skin, hair-care, make-up and sun-care products based in Greece needed to replace their outdated torque testers with up-to-date digital torque testers to guarantee production quality and to ensure their products remained sealed. Mecmesin supplied the company with two Tornado 10N.m digital torque testers, which have the ability to test tamper-evident closures, an intrinsic part of their specification.
