Acid-resistant labels

Acid-resistant labels are specially developed for use in environments where the labels come into contact with strong acids. These labels are characterised by their exceptional resistance to a wide range of organic and inorganic acids and ensure durable and clear labelling in particularly aggressive chemical environments. They are used in many industrial, scientific and commercial applications where acids are regularly used or produced.

Chemical resistance to acids

Acid-resistant labels are specially formulated to withstand contact with strong inorganic acids such as sulphuric acid, hydrochloric acid, nitric acid and phosphoric acid. These acids are commonly found in the chemical industry, metalworking and fertiliser production. In such environments, it is crucial that the labels retain their structure and legibility even when in direct contact with these aggressive substances.

Resistance to organic acids

Organic acids such as acetic acid, citric acid or lactic acid can also be used in various production and laboratory processes. Acid-resistant labels offer the necessary durability for reliable labelling in the food industry, in chemical research and in the pharmaceutical industry, without the labels being degraded or discoloured by the acids.

Corrosion protection and adhesive strength

Acid-resistant labels not only offer chemical resistance, but also high adhesion to various surfaces that may come into contact with acids. They adhere reliably to metals, plastics, glass and other surfaces that are frequently used in chemical and industrial production. They also protect the surface from corrosion and prevent unwanted detachment, even after repeated contact with corrosive substances.

Materials and technologies for maximum acid resistance

Polyester (PET)

Polyester materials are widely used in the production of acid-resistant labels as they offer excellent resistance to both organic and inorganic acids. They are particularly resistant to phosphoric acid, sulphuric acid and other highly corrosive substances.

Polypropylene (PP) and vinyl

These materials are also highly resistant to various acids and offer additional advantages such as flexibility and water resistance. These materials are frequently used in the food and pharmaceutical industries in particular, as they are highly resistant to vinegar and citric acid.

Resin-based printing techniques

Resin-based inks or thermal printing processes are used to print text and graphics on acid-resistant labels. These printing methods are particularly resistant to acids and prevent the lettering from peeling or fading under the effect of acids

Areas of application for acid-resistant labels

Chemical industry

In chemical production and processing, where aggressive acids are used, acid-resistant labels are indispensable. They are used for labelling chemicals, raw materials, waste and production materials that regularly come into contact with sulphuric acid, hydrochloric acid or phosphoric acid.

Food and beverage industry

In food processing, where acetic acid (e.g. in vinegar) and other organic acids are used, acid-resistant labels ensure that the labelling of products remains legible even after contact with cleaning agents and chemicals.

Pharmaceutical industry

These labels are a reliable solution in pharmaceutical production and for labelling chemicals and medicines that are processed with acids. They offer resistance to nitric acid and other reactive acids that are often used in the synthesis and manufacture of pharmaceuticals.

Research laboratories

In research laboratories where various acids are used for reactions and tests, acid-resistant labels provide a reliable way of labelling reagents, sample containers and chemical substances. They ensure that the labels remain legible under extreme conditions of chemical exposure.

Advantages of acid-resistant labels

Durability and resistance

They offer high resistance to a wide range of organic and inorganic acids, ensuring their longevity in extreme environments.

Chemical and physical integrity

Acid-resistant labels do not lose their adhesive strength or legibility, even after repeated contact with highly corrosive substances.

Wide range of applications

They are indispensable in various industries such as the chemical, food production, research and pharmaceutical industries and offer reliable labelling solutions in acidic environments.

Reliable application in demanding environments

Whether in laboratory research, chemical production or food processing, they ensure that the labelling of products, containers or machines remains permanently recognisable even under extreme conditions.

Acid-resistant labels are therefore an indispensable solution for companies that work in areas where aggressive acids are regularly handled and require permanently reliable labelling.
