Some label adhesives with low initial tack allow you to remove and reposition the label immediately after application, because the adhesive is designed to get stronger over time. Adhesives with a high initial tack bond almost instantly with the container, while adhesives with low initial tack have a weak bond at first and don’t reach ultimate adhesion for 24 to 48 hours. This is the holding power of the adhesive immediately upon application. If you plan to apply your labels at lower temperatures, and your containers are going to be cold during label application, you will likely need a cold-temp or all-temp label adhesive. Many adhesives, when exposed to lower temperatures, can become more viscous or thick - which can cause adhesives to collect in label applicators or can even cause failure of the adhesive. Most adhesives will maintain optimal adhesion in service temperatures from -65 to 200° F (-54 to 93° C) with a paper facestock and as high as 300° F (148.9° C) with a film facestock.Ĭold flow is an indication of how well an adhesive will adhere or bond to your containers when exposed to colder temperatures. Let’s say you apply a typical pressure-sensitive label in the recommended application temp range of 40 to 50° F and let it set for 24 hours. This describes the temperature your labels can withstand after being applied and the adhesive has completely set (see “ultimate adhesion”). If you need to apply your labels at lower temperatures - such as in a cold warehouse - then it’d be wise to choose a cold-temp adhesive, which will maintain its integrity even when applied at temperatures as low as -20° F (-28.9° C). Most adhesives have minimum application temperatures between 40 to 50° Fahrenheit (4.4 to 10° Celsius).Īpplying these types of labels at temperatures below that range will lose its pliability, become stiff and weak (called crystallization). This is the lowest temperature at which your label can be successfully applied to the container. Here, we’ve outlined the universal attributes of adhesives to help you understand what goes into choosing the “right” adhesive for your product label before reaching out to a label supplier. Your label supplier will guide you through the process, helping you choose the adhesive best suited to your product, its container and its end-use environment. It therefore stands to reason that selecting an adhesive is complicated. Yet others are designed to help labels stay snug around tight-radius containers. ![]() Some stick permanently, and some can be removed easily by the customer. Some adhesives are engineered to have good holding power at arctic temperatures. Pressure-sensitive adhesives are far from one-size-fits-all. ![]()
