Is the Gluing System Compatible With Water-Based or Hot-Melt Adhesives?

Gluing systems in flexo printers are essential for achieving secure and reliable bonding during packaging production. Whether you use water-based or hot-melt adhesives depends primarily on your application requirements and the gluing system configuration. Below, we answer the most popular questions about the compatibility and professional operation of gluing systems for flexographic printers.

What Types of Gluing Systems Are Available for Flexo Printers?

There are mainly two types of gluing systems used in the flexo printing industry:

1. Water-Based Gluing System: Uses adhesives that are dispersed in water, ideal for paperboard and corrugated board applications.

2. Hot-Melt Gluing System: Applies thermoplastic adhesives heated to liquid during application, suitable for high-speed and demanding processes.

Are Flexo Printer Gluing Systems Compatible With Both Water-Based and Hot-Melt Adhesives?

Most modern flexo printers, including models from Keshenglong&Shinko, offer compatibility with both adhesive types. However, some machines may require specific modifications or dedicated modules to switch between water-based and hot-melt systems. It's crucial to check your machine's technical specifications.

What Are the Advantages and Limitations of Each Glue Type?

- Water-Based Adhesives:

- Advantages: Environmentally friendly, easy to clean, suitable for many packaging materials.

- Limitations: Slower drying time, not ideal for high-speed production or non-porous surfaces.

- Hot-Melt Adhesives:

- Advantages: Fast-setting, excellent for high-speed applications, strong adhesion to a wide variety of substrates.

- Limitations: Requires precise temperature control, cleaning can be more challenging.

How Do I Choose the Right Adhesive and Gluing System for My Application?

- Material Type: Porous materials like corrugated board work well with water-based adhesives; coated or synthetic substrates may need hot-melt.

- Production Speed: For high-speed production lines, hot-melt adhesives are typically preferred due to their quick setting properties.

- Equipment Compatibility: Always confirm with your equipment supplier (such as Keshenglong&Shinko) regarding system compatibility and required adjustments.

Can I Switch Between Water-Based and Hot-Melt Adhesives on the Same Machine?

With the right configuration and cleaning procedures, many flexo printers support switching between adhesive types. Consult your machine’s user manual or Keshenglong&Shinko’s technical support for guidance on swapping systems and cleaning to avoid contamination.

By understanding these key points, professionals in the flexo printing industry can ensure that their gluing systems are optimized for efficient, quality production using the most suitable adhesives.
