Labels are used across a wide range of industries, including food and beverage, logistics, pharmaceuticals, consumer goods, and industrial packaging. The performance of a label depends largely on the type of glue used, as the adhesive determines how well the label bonds, how long it lasts, and how it performs under different environmental conditions.
This article explains the main types of glue used for labels in industrial applications, their characteristics, and how to choose the right adhesive for specific labeling requirements.
Key requirements for label adhesives
Industrial label adhesives must meet several performance criteria:
Strong and consistent adhesion to various substrates
Compatibility with high-speed labeling equipment
Resistance to moisture, temperature changes, and handling
Clean application without stringing or residue
Stable performance during storage and transportation
Different labeling environments require different adhesive technologies.
Common types of glue used for labels
1. Pressure-sensitive adhesives (PSA)
Pressure-sensitive adhesives are the most widely used glue type for labels. They form a bond when light pressure is applied, without the need for heat or water.
Key characteristics:
Immediate tack and adhesion
Suitable for high-speed labeling lines
Compatible with a wide range of substrates
Typical applications:
Limitations:
2. Hot melt adhesives
Hot melt adhesives are widely used for labels applied through automated labeling machines.
Key characteristics:
Fast setting and high initial tack
Good adhesion to paper, cardboard, and some plastics
Suitable for high-speed production
Typical applications:
Beverage bottle labeling
Food packaging labels
Wrap-around labels
Limitations:
3. Water-based adhesives
Water-based adhesives are commonly used in paper label applications, particularly where sustainability and cost efficiency are important.
Key characteristics:
Good adhesion to paper and cardboard
Lower environmental impact
Easy cleanup and handling
Typical applications:
Paper labels
Envelope labeling
Packaging labels
Limitations:
4. Solvent-based adhesives
Solvent-based adhesives are used in
specialty labeling applications that require strong and durable bonds.
Key characteristics:
Excellent adhesion to plastics, glass, and metal
High resistance to moisture and chemicals
Stable performance in demanding environments
Typical applications:
Limitations:
Choosing the right glue for labeling applications
| Label Application | Recommended Adhesive |
|---|
| Product and logistics labels | Pressure-sensitive adhesive |
| High-speed bottle labeling | Hot melt adhesive |
| Paper labels and packaging | Water-based adhesive |
| Industrial or chemical labels | Solvent-based adhesive |
Key factors influencing label adhesive selection
Manufacturers should consider:
Substrate material: Paper, plastic, glass, or metal
Application speed: Manual vs automated labeling
Environmental exposure: Moisture, heat, or chemicals
Regulatory requirements: VOC and sustainability standards
End-use performance: Removability or permanent adhesion
Selecting the correct adhesive improves label reliability and reduces production issues.
Conclusion
Different labeling applications require different adhesive technologies. Understanding what kind of glue is used for labels helps manufacturers select adhesives that balance performance, efficiency, and compliance.
Pressure-sensitive adhesives dominate general labeling applications
Hot melt adhesives support high-speed industrial labeling
Water-based adhesives offer cost-effective solutions for paper labels
Solvent-based adhesives serve demanding and specialty environments
Choosing the right label adhesive ensures consistent application, long-term adhesion, and efficient production.
