Label applications at extreme temperatures, especially in the range of deep-freeze and cryogenic levels, are becoming increasingly important. They require reliable closure seals and labels performing perfectly even under harsh conditions. Schreiner ProSecure has taken up this challenge, developing solutions that meet even the most exacting demands.

Applications under cryogenic and deepfreeze conditions confront labels and adhesives with new challenges. Extreme temperatures—whether during storage or dispensing—result in special adhesion and performance requirements regarding a sealing function with first-opening indication. Traditional adhesives and film materials soon reach their limits under these conditions. Especially in gene therapy where active ingredients must be stored at temperatures below -150 °C it is essential that labels reliably adhere to the substrate and are tamper-proof. But even in the less extreme deep-freeze range starting at -15 °C, labels must deliver robust and reliable performance to ensure the safety and integrity of products.

Schreiner ProSecure meets these requirements with a sophisticated modular system specifically developed for use in deep-freeze and cryogenic conditions. To perfectly address the specific demands of customers in terms of temperature and process, the portfolio encompasses a large number of adhesives and surface materials that have been comprehensively analyzed and tested by the company’s in-house research and development department. The focus is not only placed on adhesion at extreme temperatures but also on functions such as distinct first-opening indication or dispensing in the required temperature range. The combination of materials expertise and comprehensive know-how in terms of tamper evidence leads to tailored solutions delivering reliable performance even under the most difficult conditions.

Schreiner ProSecure’s extensive testing expertise is a significant success factor. To ensure that the labels work perfectly in the final application environment, many different tests are performed—both in the in-house laboratory and directly at the customer’s site. Factors like humidity, handling, and storage conditions are considered in order to test the labels’ functionality under realistic conditions. Thanks to this expertise, Schreiner ProSecure offers not only first-class solutions but also certainty that they fully satisfy the customers’ specific requirements.
