BioPak Solutions in Roquefort-les-Pins, France, are leaders in the production of Polylactic Acid (PLA) bottles. The bottles are oil-free, contain no PET or Bisphenol A, and are made 100% from carbon-absorbing plants. Using plant-based raw materials (corn) rather than petrochemicals they are eco- and vegan-friendly, require less energy to produce, are toxin-free, and are fully biodegradable.
To better evaluate the physical properties of their range of PLA bottles used for mineral water, BioPak Solutions turned to Mecmesin for help in testing their containers’ Top-Load Strength. The objective behind the testing was to identify core performance differences between resins to reveal areas for product design improvement.
To make sure that the plastic bottle can withstand the forces encountered when the screw-cap is pushed down onto it after the filling process and later when it is stacked in the warehouse, an axial compressive strength test is performed.
This methodology involved a traditional ‘single-bottle’ crush test whereby an empty bottle is compressed at a set speed until it deforms and the maximum load is recorded. A further test method was developed to perform a ‘dual bottle stack’ test, which was instrumental in differentiating the crush and buckling strength characteristics of bottles with different resins.
The Mecmesin OmniTest 5, in conjunction with VectorPro MT software, was deployed to carry out the top-load test. The peak load results were presented in newtons and incorporated into a test report, compatible with MS Excel, to enable analysis of the comparative performance of these plant-based products against those made from traditional materials.

"The Mecmesin team was very flexible and easy to work with, showing a positive `can-do’ attitude for designing tests outside the normal scope of work. Through their advanced testing equipment, Mecmesin was able to accurately identify core performance differences between resins and provide an accurate measure of bottle strength metrics.
As a result of the testing, we are able to appropriately select raw materials to suit each market, which allows us to accurately control packing, loading and supply of our products." — Sandy Nielson, Founding Director, BioPak

Adhesive test on capsulated cork stoppers
A capsulated stopper (T-top, Bar-Top or Altop) is a natural or synthetic cork stopper where the end is glued into a cap of wood, PVC, porcelain, metal, glass or other material. Testing the quality of the adhesive bond between cork and cap is a fundamental check performed by manufacturers of capsulated stoppers and their customers
Vial stopper needle penetrability residual seal force and torque testing
COVID-19 vaccines, as parenteral medications, enter the body by injection through the tissue and circulatory system. Testing the physical properties of these vital drug container systems is a key factor in quality-control testing
Hand sanitiser dispenser pump testing
Sales of antibacterial gels have soared enormously following National Health Service advice telling the public to thoroughly wash hands in order to stay protected from Coronavirus. In fact, even before the 2020 pandemic crisis, the presence of hand sanitisers had already become commonplace, not only in hospitals but also in schools, restaurants and offices.
Adhesion peel strength of COVID-19 tapes and stickers
In the wake of the Covid-19 lockdown, there have been clear guidelines issued to businesses on keeping staff and customers safe. These include wall signs encouraging people to follow hygiene guidelines through to purpose-made floor tape to help enforce social distancing rules. For successful long-lasting application to surfaces, they all rely on the stickiness provided by the humble self-adhesive.
Break-loose and sustaining force tests of pre-filled drug cartridges to ISO 11608-3
Mechanical pen injectors for delivering drugs, such as insulin, have found increasing acceptance over the traditional vial-and-syringe method. To validate new pen injector designs and maintain quality when they are mass-produced requires extensive testing.
Vaccine delivery device and packaging testing
As COVID-19 has rapidly spread around the world, there is a concerted global effort to find a vaccine. Whether administered via an oral, subcutaneous, intramuscular, intradermal, or intranasal route, vaccines need to be administered via a medical device, and these must be tested to esnure they are safe and meet stringent standards and regulations
PET preforms - repurposing production for COVID-19 test kits
PET preforms are typically blow-moulded to create the ubiquitous plastic bottles containing carbonated and still beverages. The production process to fill and seal these bottles with a screw-cap is a demanding one, so a number of tests are performed to ensure quality control specifications are met for this core packaging.
