How blister pack manufacturers identify form issues?
Finding form issues is a matter of reducing rejected materials and also sampling. And no matter what experts might think, identifying this issue first-hand is possible. The redundancy in the manufacturing steps assures there is the inclusion of some forming issues no matter how hard you try to avoid them at all times. Before blister pack manufacturers conduct the inspection process, it is important to know the sources of form issues.
Sources of Form Issues
Base material: The base material needs to be perfect, but if not, it needs to be examined as it is the root cause of the form issue.
Functionality: It is necessary to look into the process's pace, proper operation, and station settings for heating and forming.
Plug assists: The scheduling of plug-assists, mechanical plugs that pre-form the blister or tray inside the forming station. This method is often employed when it's necessary to bring the cavities down extremely far. Some of the smooth material that is now heated up is 'pushed' downwards before compressed air is used to shape out the hollow, and the remaining gap is then formed by air. This keeps the material thickness in the cavity's crucial ridges thicker than it would have been had plug-assist not been used.
New packaging materials: These, like PET, are more challenging to regulate. The elimination of PVC, which is quite simple to make, is one current initiative for many businesses across industries that have sustainability and carbon footprint measures in place. Because alternative films can be difficult to regulate in some cases, an inline monitoring system is helpful in keeping the form's quality in check.
The Inspection Process:
The inspection process conducted by the blister pack manufacturers has only 2 steps:
In-spec: This system measures the materials and components used in clear and transparent films' thickness and thickness distribution. Blisters and trays that meet specifications can be produced quickly and consistently thanks to this cutting-edge technology. When a pocket or cavity is constructed appropriately and protects its contents from outside effects, it is said to be "in-spec." The thermoformed and/or flat material is penetrated by light (sender), which is the basis for the measurement. The received signal information is converted by the receiver into a thickness in microns.
Barrier protection: The barrier to moisture is directly related to the thickness of the package's walls. Too thin allows moisture to flow more quickly and easily into the cavity, damaging the product by lowering its effectiveness and shelf life and sometimes resulting in discolouration.
Benefits of the Inspection Process
During production startup, ramp-up phases might be cut back. Outliers and quarantine are reduced.
Products are saved when a specialised feeding system is utilised and an out-of-spec cavity is found because they are not fed; only the generated material is rejected.
Packs are constantly in shape, and poorly shaped cavities—which can even meet the thickness requirements but merely look bad—are discovered right away, rather than when a patient or consumer discovers that package on the market and complains.
