Major European tube supplier turns to Mecmesin to seal quality consumer experience

One of the largest packaging tube suppliers in Central Europe specialises in laminated plastic and aluminium tube containers for the cosmetics industry. The aluminium tubes are self-sealed, with a reversible cap containing a spike for piercing the seal ready for use. The strength of the seal must keep it secure from bursting, whilst being easily opened by hand using the cap. The company required a means of testing seals against their own quality standards, imitating the consumer’s means of opening.

Mecmesin supplied a MultiTest 2.5-i test stand with a specially-constructed sample holder. Working in collaboration with Mecmesin engineers, a series of collars were made, into which the various tube samples are screwed. This avoids pressure on the tube, which is not being assessed. The motorised stand presents the correct plastic cap to the seal in a controlled way. A 1000 N intelligent loadcell records the applied force throughout the piercing cycle. As the Emperor™ software acquires the data, it presents the characteristics of the breaking seal as a real-time graph on the computer screen.

The software has a library of test sequences for various products so that instant pass/fail indication is given. All test data is stored for analysis and comparison. Resetting the stand and test programmes for different samples is quick and simple. The major advantage to the company is the speed of throughput for test samples, the accuracy of the measurement, and the immediacy of results.

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.
