Productos Colcar adhesivos hotmelt etiquetado PET

How many times have you participated in a raffle or contest for which you needed a soft drink label? Many, right? And, in some cases, getting the label off the ground was a very difficult task. Explanation can be found in that, surely, bonding has been carried out using hotmelt adhesives, very resistant and durable, ideal for plastic containers. Next, we will tell you about its benefits.

The label of a product is a “piece of paper, cardboard or other similar material, generally rectangular, that is placed on an object for identification, valuation, classification, etc…” This is one of the meanings that the Royal Spanish Academy collects in its dictionary to define this term specifically known to all.

It is an element that, in addition to identifying the product, projects its image and that of the manufacturer, and our objective is to inform about the characteristics of the product, how to use it and, in some cases, legal aspects related to the handling and use of the product  itself.

To the consumer, label not only allows them to learn more about the product, but also helps them in their decision-making. Because, let’s not forget that the image is one of the factors that interpose in the purchase decision. In this sense, as we already mentioned in the post about the benefits of hotmelt adhesives for food packaging, the proliferation of new references forces the manufacturer for constant innovation and product differentiation with the aim of obtaining the attention of the consumer by designing personalized labels.

Hotmelt adhesives deliver the best results for labelling plastic containers

Among all the adhesives that Productos Colcar custom designs for food labeling, today we are going to focus on those for plastic bottles, with PET being the most popular type of plastic among food and non-food product packaging due to its resistance, thermal stability and transparency.

When opting for one or the other, we must know that each bottle requires certain glue that must be adapted to the characteristics of the labeling and the material from which the container is made.

The most effective solution is the use of hotmelt adhesives. Using this alternative of casein adhesives is optimizing for gluing paper or plastic labels on plastic containers, but also on materials such as glass, metal, paper and cardboard.
