Custom Self-adhesive Paper Materials Manufacturers

In the food industry (such as cold chain labels), how to solve the problem of adhesive failure of self-adhesive paper materials or paper label materials in low temperature environments?

1. The impact of low temperature environment on adhesive performance
Increase in adhesive viscosity:
Under low temperature conditions, the molecular movement of the adhesive slows down, resulting in increased viscosity and poor fluidity. This makes it difficult for the adhesive to fully wet the surface of the adherend, affecting the bonding effect.
Decreased cohesion of the adhesive:
Low temperature may cause the cohesion of the adhesive to decrease, making it more likely to undergo cohesive failure when subjected to external forces, that is, the adhesive itself breaks instead of separating from the adherend.
Changes in the surface energy of the adherend:
Under low temperature conditions, the surface energy of the adherend (such as food packaging materials) may change, affecting the wettability and bonding strength of the adhesive.
Moisture condensation:
In a cold chain environment, due to temperature differences, moisture may condense on the surface of the self-adhesive paper or label to form a water film. The presence of a water film weakens the interaction between the adhesive and the adherend, resulting in bonding failure.
2. Strategies to solve adhesive failure in low temperature environment
Choose adhesives with excellent low temperature performance:
For low temperature environment, adhesives with low temperature flexibility, good cold resistance and high bonding strength should be selected. For example, some hot melt adhesives, pressure sensitive adhesives or specially formulated water-based adhesives can still maintain good bonding performance at low temperatures.
Shanghai Baozhongbao Adhesive Products Co., Ltd, as one of the earliest domestic companies to produce self-adhesive sheets and paper materials, has rich experience in adhesive solutions. The company can provide different adhesive solutions such as acrylic, solvent-based adhesives, hot melt adhesives, etc. to meet customers' application needs in low temperature environments. By continuously optimizing the adhesive formula, the company can ensure that it still maintains good bonding performance under low temperature conditions.
Optimize the design of self-adhesive paper or label materials:
Choose substrates suitable for low temperature environments, such as low temperature resistant paper or film, to ensure that the material itself will not deform or become brittle at low temperatures.
Enhance the surface treatment of paper-based label materials to improve their wettability and bonding strength to adhesives. For example, the polarity and roughness of the material surface can be improved by methods such as corona treatment or plasma treatment.
Improve the coating process of adhesives:
Use a uniform and thin layer coating method to ensure that the adhesive can fully wet the surface of the adherend at low temperatures.
Control the coating amount to avoid the adhesive being too thick, which makes it difficult to solidify or form an effective bonding layer at low temperatures.
Strengthen pretreatment before use:
Before labeling, clean and dry the surface of the adherend to remove pollutants such as grease, dust and moisture to improve the bonding effect of the adhesive.
For particularly low temperature environments, consider preheating the self-adhesive paper materials or label and the adherend to a suitable temperature before labeling to improve the fluidity and wettability of the adhesive.
Develop an intelligent temperature control system:
Use the Internet of Things and artificial intelligence technology to develop an intelligent temperature control system to monitor and adjust the temperature in the cold chain environment in real time to ensure that the self-adhesive paper or label is within a suitable temperature range during labeling and storage.
Shanghai Baozhongbao Adhesive Products Co., Ltd has introduced the Internet of Things and artificial intelligence technologies to build smart factories, achieve precise control of the production process and optimize resource allocation. This technical foundation provides strong support for the development of intelligent temperature control systems, which helps to further solve the problem of adhesive failure in low temperature environments.
Use environmentally friendly adhesives and water-based processes:
Environmentally friendly adhesives and water-based processes not only meet the requirements of current environmental regulations, but also help reduce the emission of volatile organic compounds (VOCs) and protect employee health and environmental safety.
Water-based adhesives have good wettability and fluidity at low temperatures, can form a uniform bonding layer, and improve bonding strength.
Shanghai Baozhongbao Adhesive Products Co., Ltd uses solvent-free coating and water-based processes to reduce volatile organic compound emissions. At the same time, it actively develops new bio-based adhesives to replace traditional petrochemical materials with renewable resources, significantly reducing carbon footprint. These environmental practices provide a sustainable solution to the problem of adhesive failure in low temperature environments.
