Avoid Label Edge Lifting With Correct Materials

Many customers struggle with labeling on small-diameter tubes — one of the most common issues being label edge lifting or curling. Based on our experience in label manufacturing, here are a few practical tips to help you reduce or avoid this problem: 1. Choose a solvent-based adhesive when possible. Solvent adhesives tend to offer better stability and stronger cohesion. While hot melt adhesives have high initial tack, they often have lower cohesion and may lead to adhesive stringing and curling issues over time. 2. Option for thinner face stock materials. Materials like 60gsm semi-gloss paper, PE, and 54U synthetic paper are commonly used and better suited for curved surfaces due to their flexibility and thinness. 3. Be cautious with lamination if using paper face stock. Avoid film lamination on paper labels for small-diameter applications. The added tension from the film can cause curling. Also, when designing labels, try not to fully connect the start and end of the label — leaving a small gap can help release stress and reduce curling. 4. Always test before full production. Even with the right materials, testing is essential. Different substrates, tube diameters, and application conditions can all affect the final label performance.
