Printing Challenges When Coding onto Sleeve Packaging<\/strong><\/h2>\n\n\n\n

Sleeve packaging is a popular choice across many consumer goods sectors, particularly in food, beverage, personal care and household products. It offers strong shelf appeal, 360-degree branding opportunities and the flexibility to package products of different shapes and sizes. <\/p>\n\n\n\n

However, when it comes to applying batch codes, best-before dates, lot numbers and other traceability information, sleeve packaging can create some specific challenges. Curved, flexible, glossy <\/strong>or shrinkable materials can make it difficult to achieve a consistently clear, accurate and durable code. <\/strong>For manufacturers, getting this right is essential. A poor-quality code can affect product traceability, create compliance risks and lead to costly rework or waste. <\/p>\n\n\n\n

Choosing the right coding and marking solution, combined with the correct setup, ink and line integration, can help manufacturers overcome these issues and maintain reliable print quality at production speeds.  <\/p>\n\n\n\n

Why sleeve packaging can be difficult to code<\/strong><\/h2>\n\n\n\n

<\/p>\n<\/div>\n\n\n\n

Unlike flat cartons or labels, sleeve packaging often involves materials that are curved, flexible, stretchable or shrinkable. This can make the surface particularly difficult to code onto. Even small variations in product position, sleeve tension or printhead alignment can affect the final code result. <\/p>\n\n\n\n

The main challenges in coding include:<\/strong><\/h2>\n\n\n\n

Code distortion<\/strong> – Sleeves may move, stretch or shrink after the code has been applied. If the print area is not carefully selected, the code can become distorted, warped or compressed, making it difficult to read. <\/p>\n\n\n\n

Print drift and misalignment<\/strong> – High-speed packaging lines leave little room for error. If the product position varies on the conveyor, or if the sleeve is not presented consistently to the printer, the code may drift from its intended location. For packs with limited clear coding space, accurate placement is particularly important. <\/p>\n\n\n\n

Ink adhesion<\/strong> – Sleeve materials can include glossy card, films, coated surfaces and other difficult substrates. These surfaces may be less absorbent than standard porous packaging, making ink adhesion more challenging. If the wrong ink is used, codes can smudge, fade or rub away during handling, packing, transport or storage. For food packaging in particular, specialist inks may be required to adhere to challenging substrates, including surfaces affected by grease, moisture or coatings. <\/p>\n\n\n\n

Production speed<\/strong> – Modern packaging lines are designed for efficiency, but faster line speeds can make consistent coding more difficult. The printer must be able to keep pace without compromising print quality, especially where products are closely spaced or moving on curved or uneven surfaces. <\/p>\n<\/div>\n<\/div>\n\n\n\n

The consequences of coding errors<\/strong><\/h2>\n\n\n\n

Coding and marking may only be one part of the packaging process, but errors can have a significant impact.<\/p>\n\n\n\n

Product recalls<\/strong><\/h3>\n\n\n\n

If a batch code, date code or traceability mark is unreadable or missing, affected products may be difficult to identify in the supply chain. In regulated sectors such as food and beverage, this can increase the risk of recalls or compliance issues. <\/p>\n\n\n\n

Production downtime<\/strong><\/h3>\n\n\n\n

When coding errors are discovered, production may need to stop while the issue is investigated and corrected. This can affect throughput, create delays and add pressure to operators and maintenance teams. <\/p>\n\n\n\n

Increased waste<\/strong><\/h3>\n\n\n\n

Incorrectly coded products may need to be rejected, reworked or repackaged. This creates unnecessary material waste, increases costs and can reduce overall line efficiency. <\/p>\n\n\n\n

Choosing the correct ink and technology<\/strong><\/h2>\n\n\n\n

The right coding technology will depend on the sleeve material, production speed, code requirements and operating environment. <\/p>\n\n\n\n

Best practice for coding onto sleeve packaging<\/strong> <\/h2>\n\n\n\n

To reduce the risk of errors, manufacturers should build coding considerations into the packaging process as early as possible. <\/p>\n\n\n\n
