The packaging industry is a dynamic and ever-evolving sector, where adhesives play a critical role in ensuring the safety and integrity of products during transportation and storage.
In addition to keeping packages securely sealed, adhesives also contribute to the appearance and functionality of packaging.
This article explores the different types of adhesives commonly used in the packaging industry, their specific applications, and how ongoing innovations are driving this field forward.
Types of adhesives in the packaging industry
Pressure-sensitive adhesives
Pressure-sensitive adhesives (PSAs) maintain their tackiness and adhere instantly when pressure is applied. They are commonly used in labels, tapes, and self-adhesive materials.
These adhesives are ideal for temporary or removable applications, such as food product labels. At Worldwide Foam, we offer a range of pressure-sensitive adhesives to meet various packaging needs.
Hot melt adhesives
Hot melt adhesives (HMA) are thermoplastic materials applied in a molten state, which then solidify as they cool. They are widely used in packaging due to their rapid setting time and strong bonding properties.
These adhesives are ideal for sealing boxes and cartons, tray forming, and packaging products like chocolates and frozen foods.
Water-based adhesives
Water-based adhesives are known for their consistency and stability. They are frequently used in labeling, laminating, and paper packaging.
In addition, water-based adhesives are an eco-friendly option because they are biodegradable and emit no volatile organic compounds (VOCs) during application.
Solvent-based adhesives
These adhesives contain solvents that evaporate after application, leaving behind a durable bond. They are often used in applications requiring enhanced resistance to moisture and certain chemicals.

There are several high-quality adhesives available to meet the varied needs of the packaging industry. Below, we highlight three widely used options, each with unique features that make them ideal for specific applications.
1) Double-coated tape
This tape is coated on both sides with pressure-sensitive, rubber-based adhesive.
Applications:
General-purpose bonding on semi-smooth surfaces.
Excellent performance on low surface energy (LSE) substrates.
Ideal for gasketing, foam assembly, insulation, and seals.
2) Adhesive Transfer Tapes
These tapes feature acrylic adhesive, designed to bond to a wide variety of surfaces, including foams, fabrics, and other substrates.
Applications
High-performance, precision bonding in the gasketing industry.
Ideal for material combinations that require good shear strength at high temperatures.
3) UC Butyl
A butyl-based adhesive formulated for high-speed converting processes, particularly in gasket cutting. It includes a mesh carrier to provide stability and allow for clean, precise cuts.
Applications
Works well with foams and other materials.
Widely used in the automotive and electronics industries, where strong, flexible seals are required.
