Adhesive labels for refrigerated foods must maintain their integrity and legibility from the moment they are applied until the product reaches the consumer. In a sector where humidity, cold, and health regulations are constant factors, choosing the wrong one can lead to a failure in the quality chain. It’s not enough to look good; it must be durable, adhere properly, and comply with current regulations.
At Adhesivas Ibi, we are well aware of these challenges and we can help you choose the best solution for each type of refrigerated product.
What challenges does labeling on refrigerated products present?
Cold-resistant labels must meet very specific technical requirements to maintain their functionality. These environments require materials, adhesives, and finishes that guarantee impeccable performance at every stage of the logistics cycle.
These are the most common:
- Humidity, condensation, and low temperatures: These cause alterations to the packaging surface and make it difficult to apply the adhesive if the appropriate adhesive is not used.
- Risk of adhesive detachment: If the label does not adhere well from the start, it can peel off in the freezer or during transport.
- Transportation and storage conditions: These require materials that can withstand constant cold, thermal shock, and continuous exposure to moisture.
- Direct or indirect contact with food: This requires working with solutions that comply with food safety regulations, without migration or residue.
Taking these factors into account allows you to reduce errors, maintain traceability, and comply with regulations without incident.
Types of adhesive labels suitable for cold
Choosing labels that won’t peel off in the cold isn’t just a matter of material. The type of adhesive, surface finish, and substrate treatment also play a role.
Special adhesives for low temperatures
Refrigerated products require labels that won’t peel off in the refrigerator, and that perform well even when applied to wet or cold packaging. These adhesives maintain their adhesion flawlessly from the first contact, ensuring the label’s durability throughout the entire cold chain.
Plastic materials vs. technical paper
In situations where humidity is constant, it’s advisable to use durable substrates. Moisture-resistant technical paper is an effective option for products that require a more natural or eco-friendly look, while plastic materials offer better performance against grease, water, and extreme temperatures.
Water and grease resistant labels
When the contents of the packaging contain oils or liquids, you need plastic food labels that can withstand splashes and stains without deteriorating. This material maintains the print intact and adapts well to automatic or manual production lines.
Adhesives approved for food use (FDA/BRC)
Working with FDA-approved BRC-certified labels ensures that the labeling system meets all health and legal requirements. They are the best option for products that may come into contact with the label during use or storage.
Keys to ensuring a secure and long-lasting adhesion
Labels for refrigerated products should be selected based on the product type, packaging, application temperature, and life cycle length. An adhesive that performs well in cold conditions, combined with a waterproof material and a good finish, ensures that the label remains firm, legible, and functional throughout the entire logistics journey. Working with specialized suppliers allows you to avoid common pitfalls and tailor the solution to each specific need.
Compatibility between adhesive and type of packaging (PET, glass, cardboard)
Adhesive performance depends on the type of packaging, the application environment, and the product’s end use. Labels for fresh produce must be precisely tailored to each of these factors to avoid failures under real-world conditions.
- Application on wet or frozen surfaces: The adhesive must maintain its effectiveness even in the presence of condensation or frost, which is very common on refrigerated packaging lines.
- Adhesion and durability testing in cold storage: Testing the entire system under real-world conditions allows for anticipating problems and confirming that the label will hold up without peeling or deteriorating.
- Real-life examples of failures due to poor adhesive selection: cardboard packaging with inadequate labels tend to peel off when absorbing moisture; on glass, some adhesives lose strength after sudden temperature changes.
Selecting the right adhesive system for the packaging type prevents critical errors and guarantees functional labeling throughout the logistics cycle.
Regulations to take into account in food labeling
European food label regulations establish strict requirements to ensure consumer safety. The materials used must demonstrate that they do not transfer substances to the food or alter its composition, both in the case of the backing and the adhesive, complying with EU and FDA food contact regulations.
Furthermore, BRC Packaging certifications require rigorous control of the manufacturing process, including traceability, hygiene, and technical documentation from the source of raw materials to the final product.
Every labeling system must be supported by supplier declarations of conformity attesting to its suitability for food use and available for any audit.
How a specialized provider can help you
Having a specialist in cold-weather food labels gives you access to proven solutions tailored to your needs. Here are some of the key benefits:
- Technical advice and samples: Analyzing the product and validating actual performance before production prevents errors and optimizes results.
- Customization by product and logistics: Adapting the solution to the type of packaging, format, and distribution improves overall performance.
- Traceability and documentary compliance: Having technical documentation and certifications facilitates audits and demonstrates compliance.
At Adhesivas Ibi, as manufacturers of adhesive labels, we understand the technical requirements of labels that must function in very cold environments.
