Introduction

Packaging inks play a crucial role in the aesthetics and functionality of packaging materials. Additives are vital components that enhance the performance, durability, and appeal of these inks. This article delves into the various additives used, their functions, and specific solutions provided by Topwin company.

Types of Additives Used in Packaging Inks

Additives in packaging inks are diverse, each serving a unique purpose. Some of the critical additives include:

• Dispersants: Enhance pigment dispersion and stability.
• Defoamers: Prevent foam formation during ink production and application.
• Slip Agents: Improve substrate glide and resist scratching.
• Wetters: Enhance substrate wetting for better ink adhesion.
• Resins and Binders: Provide film formation and adhesion properties.

Functionality of Additives

Different classes of additives perform distinct functions to enhance the overall ink performance.

• Dispersants: Optimize pigment dispersion by reducing agglomeration, presenting a uniform color output. Typical usage ranges from 0.5% to 3% of the total formulation weight.
• Defoamers: Provide foam control to ensure smooth ink application. Usage concentration is typically between 0.1% to 0.5%.
• Slip Agents: Offer enhanced slip and anti-blocking properties. These are used at concentrations of 1% to 5%.
• Wetters: Provide improved wetting of substrates by reducing surface tension. The dosage is commonly around 0.2% to 0.8%.
• Resins and Binders: Integral for ink film formation and substrate adhesion, employed at higher concentrations, often exceeding 20% of formulation weight.
