6+1 Flexo Slotter Solution: Keshenglong’s Answer to High-Precision Corrugated Printing

Introduction

As the packaging industry evolves to meet increasing demands for personalization and fast delivery—especially in sectors like e-commerce and FMCG—printers and box manufacturers face growing pressure to handle diverse, small-batch orders efficiently. To meet this need, Keshenglong developed the innovative “6+1” high-precision flexo printing and slotting line, quickly becoming a benchmark in the corrugated packaging industry.

What is the “6+1” Flexo Slotter Technology?

The “6+1” setup includes six color printing units and one additional functional unit, which can be used for varnishing, die-cutting, or slotting. This design enables versatile production in a single pass.

Key Features:

• Full servo-synchronized control ensures tight registration with a print accuracy of ±0.25mm.

• Supports high-resolution halftone printing—up to 133 lines per inch (LPI).

• Compatible with eco-friendly water-based inks and low-VOC formulations.

This combination of flexibility, precision, and sustainability positions the 6+1 system as a complete solution for modern packaging needs.

Solving Common Printing Challenges for Clients

1. Enhancing Brand Identity with High Print Quality

Clean lines, sharp text, and accurate color reproduction enable packaging that boosts brand visibility. Customers in cosmetics, food, electronics, and home appliances benefit from packaging that communicates quality at first glance.

2. Maximizing Efficiency with Integrated Functions

The all-in-one workflow—from multi-color printing to die-cutting and slotting—reduces handling time. The auto job change feature minimizes downtime, with average changeovers taking less than 3 minutes, ideal for multi-SKU orders.

3. Versatile Substrate Compatibility

The system handles a wide range of corrugated materials, including E, F, B, C flutes and double-wall combinations, ensuring suitability across industries.
