How Small Factories Get Crisp Dates on Glossy Kraft Paper Without CIJ Expense

The Secret to Perfect Small-Batch Coding: How to Master Printing on Glossy Kraft Paper Bags

Small food manufacturers and e-commerce brands need reliable date codes (MFG/EXP) on their packaging, including glossy Kraft paper bags. The key difficulty is cost and achieving adhesion on slick surfaces. Standard industrial coders are often too large and expensive for small-scale operation, making them inefficient.

This tutorial shares a practical marking technique focused on cost savings and compliance. We address how to mark glossy, non-porous paper without smudging or failure.

The Simple Technique: Use the Right Tool, Not the Most Expensive One

Many small factories make the mistake of choosing porous ink, which smears instantly on glossy paper. The solution is specialized equipment: an industrial stamper paired with **instant-adhesion ink** designed for smooth film and coated paper.

This method offers:

• **Low CAPEX:** Minimal investment compared to automated CIJ systems.
• **Instant Adhesion:** Ink bonds immediately to the paper's slick coating, guaranteeing zero rub-off.
• **Versatility:** The tool handles multi-line codes (MFG, EXP, Batch) and works on irregular shapes beyond just flat bags.

Implementation Tip: Ensure Consistent Pressure

For best results on glossy bags, apply firm, even pressure. This guarantees full ink transfer and helps the code cure instantly for a sharp, legible mark. This technique ensures your codes meet all food safety and regulatory standards without forcing you into an unnecessary budget expenditure.

If you are looking for a reliable, low-cost solution for small-batch product coding, this technique provides professional quality at a fraction of the price. To see our full range of industrial marking solutions, please visit our website today.
