Struggling with Smudged Printing on Films and Foils? Here’s the Solution

Why Coding on Flexible Packaging Demands a Different Approach

Coding challenges can arise when printing on flexible films and foils in contrast to printing on rigid substrates. Flexible packaging can stretch, wrinkle and move which can impact the code adhesion. It’s vital for manufacturers to have coding solutions that remain legible and durable for flexible packaging. Choosing the right printer for flexible packaging lines is essential for maintaining high code quality and preventing costly rework.

Understanding the Surface Challenges of Films and Foils

Films and foils typically have low surface energy, which can make it difficult for inks to bond effectively. Additives, laminates, or glossy finishes can further complicate print adhesion. Some substrates may also be heat sensitive, restricting the technologies that can be used. To ensure crisp, reliable codes, manufacturers must ensure their coding technology is suitable for their lines, along with the correct ink formulation and substrate compatibility.

CIJ, TTO, or Laser? Choosing the Right Technology for Films and Foils

There is no one-size-fits-all approach for coding flexible packaging, and selecting the right technology is critical. Some key coding technologies at Linx include:

Understanding the strengths of each technology ensures the code meets compliance, brand, and durability requirements.

Maintaining Code Clarity at High Production Speeds

High-speed lines can challenge print quality, especially on fast-moving flexible substrates. Smudging, misalignment, or incomplete prints can occur when the coding system isn’t optimised for rapid movement. Printer features such as consistent ink droplet placement, accurate ribbon control, and intelligent printhead alignment help maintain clarity even at demanding speeds. Reliable coding also supports overall equipment efficiency by reducing downtime.
