Together, we will search for the best solutions.
Machines may be freely modified or constructed from scratch in accordance with the customer’s vision and their needs. This offer is not restricted to individual machines. We also implement complex and advanced-projects such as automated production lines incorporating state-of-the-art industrial automation.
The blister packaging production is without doubt one of the most popular technological solutions in line with the principles of ecology, recycling and optimising the management of plastics. What is a blister and how to make this type of packaging?
A blister is a type of packaging material consisting of several layers: a bottom layer made of cardboard, foil or a combination of these materials and a top layer. As they are by design transparent and made of plastic, the goods in question may be viewed freely and without the need for packaging. One important feature of blister packaging is that it is contoured. This allows it to adapt to the shape of the object that is being protected. As a result, the product contained between the two layers – blister and embossing – is on the one hand very thoroughly protected and on the other hand – far more accessible for, for example, visual analysis. That is why blister packaging is so popular in a variety of industries that need a combination of both.
We can therefore assume that a blister is a colourless container of varying shape, with the main purpose of displaying the product effectively while maintaining all its protection. This is facilitated through the specific nature of this packaging, formed from a vacuum thermoformable foil.
The development of blister packaging perfectly aligns with ecological considerations and the maximisation of the use of plastics. The most common materials used to produce this type of packaging are:
Through their use, it is possible to seamlessly tailor the blister packaging to the specific product premise. The plastics used ensure that the packaged goods are well protected and, at the same time, very well displayed for those interested in buying them.. Given the fact that blister packaging itself can be shaped to a specific design, there is nothing to prevent it from having, for example, a base that is ideal for placing on display or a hang tag. It is also important to consider the properties of materials made from flexible polymers. They can either be transparent or not – providing both thermal or light protection.
It is crucial to use suitable machines – these should combine quality and the possibility of series production. This process of creating blister packaging may be based on Zemat equipment. The most important machine for this process is FORMA, namely the vacuum thermoforming machine. With a special thermoplastic foil as the basic processing base, the foil is formed into the correct shape under vacuum and temperature on a special tooling (mould). Alternatively, it can be immediately cut on the cutting modules available for the machine. They allow an efficient and economical moulding process whether for small or larger production batches. This is how the main part of the package is being prepared.
The back of the packaging – the so-called backs – should a cardboard box be used, can be created without problems using the possibilities provided by the ROLLMAT die-cutting machines. Once the die-cut is prepared to a suitable design, a pre-printed cardboard template is applied. In one pass of the machine – after cutting from the die-cutter – there can be up to several dozen usages.
The final part of the process involves connecting the two elements together permanently. The welding process may also be performed on machines manufactured by Zemat. Depending on the material type, this is carried out using the TERMA heat sealers or high frequency welders, e.g. SIGNA DUO, OPTIMA.
Blisters may adopt different formats. These include sealed packaging, but also other types of closure – standard sealing, snap-fit, roll-up, and glued. Also, the inserts themselves, with their levelling specifications , inserted into customised boxes, are considered to be blisters.
A somewhat different division of blisters involves products:
One standard use of blister packs would be for tablets – of course taking into account that the base would not be made of cardboard, but of aluminium foil. In a somewhat different form, blister packaging is used for other articles that need to both protect the product and show it to the recipient or explain the type and model. This creates blister packaging for small domestic appliances, toys, light bulbs, chemicals and cosmetics, automotive products or office products, to name but a few.
Undoubtedly, being able to showcase an item provides an important marketing advantage. Merchandising analyses suggest that when customers are presented with two identical products – sealed in standard packaging and in blister packs with the possibility of display – they are more likely to choose the latter.
Blister packaging has proved very popular due to a number of its advantages. Among the most important of these are certainly:
As a response to the growing demand for eco-friendly and functional packaging, blister manufacturers have been introducing innovations such as:
Blister packaging represents a versatile solution used across a range of industries due to its visual appeal, product protection and personalisation capabilities.
Our role is not only to deliver our customers decent, reliable machines for the blister packaging production, but also to provide extremely important technical support during their use. As experts in industrial technology, we have the best insights into the machines we have developed, which we share with our customers so that they can efficiently implement the new solutions in their companies and then ensure that they are operated correctly to achieve optimum production results and the desired high blister quality. The technical support we offer is essential to ensure the correct operation and performance of the machines that we sell to our customers. Our technical service performs its tasks under warranty and post-warranty service, with these tasks including inspection, repair and maintenance of machines.
