Glues for recyclable PET

At Almetac we have for years developed both cold and hot melt adhesives that ensure that bottles can be returned, washed and recycled. 

ADHESIVE COHESION

The boxes are opened and when we check both surfaces, we find that the hot melt adhesive has penetrated, however, the adhesion has not been sufficient, and the flaps remain open.

Why synthetic adhesives can be used in returnable lines

No sólo el adhesivo afecta en el lavado de las etiquetas, hay otras variables que intervienen como el tipo de papel y su fabricación, los métodos de impresión, el barniz de las etiquetas o la película plástica.

You will never run out of glue

What makes the real difference between a conventional service and the one we offer you at Almetac can be summed up in a single concept that is part of our DNA: commitment.

Torn labels

The problem

The bottles arrive at the boxer or warehouse with the labels broken.

The origin of the problem

The problem may be caused by one of the following variables not being adequate : 

The characteristics of the paper in terms of absorption capacity and wet strength are fundamental parameters.

Additionally, the initial tack of the adhesive and its evolution in the wet are also decisive.

FOAM IN THE WASHER

The problem

During the bottle washing process there is an uncomfortable foam formation.

The origin of the problem

The problem may be caused by the wrong type of defoamer being used, or by the wrong concentration.

Some adhesive formulations are more prone to foaming than others.

New training success at Heineken Sevilla

Last November 6, the technical director of Almetac, Jesús Callejón, moved to the Heineken plant in Seville to give a new training course to line managers, maintenance managers, machinists and packaging managers.

Almetac goes one step further in adhesives with bucket resistance

The bottlers grow in sales based on a growing export. The bottles travel more and more, and arrive in markets with more diverse cases, so the demand of this characteristic increases.

Label Drop

Glass bottles in untreated virgin state generate friction with each other during transport (glass factory-bottling site-market), resulting in a scratched appearance of the bottle not accepted by the market.

The adhesive to be used must always have a surface tension lower than the bottle.

When collars and labels fall, the Surface Tension of the bottle should be studied and the adhesive adapted to that batch of bottles.

Foamy glue in buckets

Deterioration of the glue observing considerable thickening and foamy appearance, which can have an impact on the properties of the glue and therefore on labeling conditions. This problem forces you to remove unconsumed glue cubes.

Labeling machine spiderwebs

Appearance of spider webs around the elements of the labeling machine.

This effect is cumbersome and has an impact on the cleaning and maintenance of the labeling machine, in addition to generate lot of expectation because it is something that usually appears spontaneously and not continuously.

Do you know what the most biodegradable glues are?

Casein and starch glues are glues of natural and sustainable origin. Almetac is a leader in the sector that produces this type of glues since its foundation in 1984. Almetac has specific formulas with a positive differential impact on the consumption of water in a treatment plant compared to other types of adhesives.

First training course 2020

The first training course for 2020 took place on 15 January at the Mahou Alovera plant. On this occasion, the course was given by the technical director of Almetac, Jesús Callejón, and by the expert in the field, Luis Mari Aldazabal.

Wrinkles on the label

The labels appear with bubbles or wrinkles on their surface which can generate major problems in the lines, as well as damaging the brand image.
