Testing Peel Quality of Pharmaceutical Labels

With the increasing spread of omicron and delta variants across the nation, and the delivery of vaccinations against them rising speedily, pharmaceutical industries are gaining more and more demand in the market. With the market demanding increased deliveries of medications, covid vaccinations manufacturers are getting dependent on faster and quicker pharma packaging.

However, the issues with faster packaging firms are that they may miss out on the most important thing which is the quality aspects of pharma packaging. And when we say quality control, package labelling plays a vital role. Patients and doctors, suppliers, distributors, pharmaceuticals, all rely enormously on the package labels. The important information and date printed on the labels are mandatory and necessary.

The problem arises if these labels are not stuck properly to the product package. That happens due to poor bonding forces between the label and the package surface.

Potential peel issues that a Pharma bottle label may experience

Poor peeling strength in pharmaceutical packaging labels may result in the removal of labels during movement in the production line, while they are handled in storage and while they are getting transported. This rough mishandling of the package can lead to the removal of poorly bonded packaging labels. Medicinal products without a label have no credibility. The patients can’t consume the medicine without the knowledge of its chemical composition, manufacturing and expiry date. Hence, resulting in complete loss of the product just because of the removal of package labels.

How to evaluate the peel strength of pharma packaging labels?

Peel strength or bonding or adhesion strength of a pharma packaging label can be evaluated through a peel strength test. This test helps evaluate the packaging label quality and check its adhesion strength. To conduct the test, the sample label is clamped by two ends and pulled into opposite directions. The force applied to peel out the label sample is recorded. This force value will help categorize the quality of the peeling label.

Peel Strength Tester - The ultimate bonding strength tester for labels

Peel Strength Tester brings high accuracy testing procedure with features like high accuracy in elongation test, allowing a Vertical Clearance of 400 mm during the test. It has an Exterior Body Painted with Powder coated for an anti-corrosive effect in the long run. The test values are displayed on a Digital LCD Display Screen with a high level of accuracy. It delivers a Capacity Range of 20 Kgf/ 50 Kgf allowing a wide range of samples to be tested. It is equipped with an ‘S Type’ load-cell that allows a uniform application of peeling forces. The machine allows a Speed Range of 40mm/min to 400 mm/min so that a user can conduct a variety of testing ranges.

It comes with vice type test jaws that are by default available with the equipment, otherwise, other types of clamps are also available for conducting the test. The digital test screen records test results with high precision and are accepted across the globe. The test values recorded includes peeling force application, Load & Elongation values and keeping the memory of multiple test procedures for future comparison among products.

The machine uses an efficient single screw mechanism to deliver smooth testing and is equipped with a high brand and quality induction motor with a dedicated gearbox for accessing smooth speed variations and maintaining speed during testing procedures.

Peel / Seal / Bond and Adhesion Strength Tester

It has Inbuilt safety features like Over Load Safety and Over Travel Safety to ensure that the user conducts safe testing procedures. The equipment has Optional Features like a Computer interface through RS232 Communication that connects the machine to the computer system and delivers strategical graphs on load v/s elongation (stress v/s strain) and accessible in the form of an excel sheet.
