How to Select the Right Hot Melt Adhesive for Your Packaging Application

‍Packaging is essential to any business that deals with physical products. It's what keeps your products safe during transportation and storage, and it's what makes them stand out on the shelves. However, have you ever thought about what holds your packaging together? That's where hot melt adhesives come in. Hot melt adhesives are a popular choice for packaging applications because of their superior bonding properties.


According to Global Market Insights, hot melt adhesives market is projected to expand at 7.5% CAGR between 2023 to 2032. However, with so many different types of hot melt adhesives available, selecting the right one for your packaging plication can be ad aunting task. In this article, we'll guide you through the process of selecting the right hot melt adhesive for your packaging application, so you can ensure your products stay safe and secure throughout their journey from the factory to your customers' hands.


Factors to Consider When Selecting Hot Melt Adhesives

When selecting a hot melt adhesive, there are several factors to consider. The first factor is the type of substrate you'll be bonding. Different substrates require different adhesives, so it's important to choose the right adhesive for your specific application.


The second factor is the environmental conditions the adhesive will be exposed to. Will the adhesive be exposed to extreme temperatures or moisture? If so, you'll need to select an adhesive that can withstand those conditions. The third factor is the speed of production. Some adhesives require a longer set time than others, so it's important to choose an adhesive that can keep up with your production speed.


Types of Hot Melt Adhesives

There are several types of hot melt adhesives available, each with their own unique properties. Some of the most common types of hot melt adhesives include:

  • Ethylene Vinyl Acetate (EVA): EVA is a versatile adhesive that is commonly used in packaging applications. It offers excellent adhesion to a wide range of substrates and is available in a variety of formulations to meet specific bonding requirements.

  • Rubber Base: Rubber base hotmelts are ideal for bonding various poly film laminated carton stock. They offer good adhesion strength. TECHNOMELT 246A is a rubber base hotmelt.

  • PSA Hotmelts: Pressure sensitive adhesives, also known as PSAs, are a type of non-reactive adhesive that forms a bond with a substrate through the application of pressure. Hotmelts that exhibit some PSA characteristics are known as Semi-PSA hotmelts.. TECHNOMELT GA 007A is a great Semi-PSA option.

  • Metallocene: Metallocene adhesives are commonly used in food packaging applictions. They offer excellent adhesion strength and are FDA approved for indirect food contact. Supra 450 is a great option for food packaging.


Understanding the Packaging Application

To select the right hot melt adhesive for your packaging application, it's important to have a thorough understanding of the application itself. What type of packaging material will you be bonding? Will the packaging be exposed to extreme temperatures or moisture? What is the speed of production? By answering these questions, you'll be able to choose an adhesive that is specifically designed to meet your bonding requirements.

Adhesive Application Methods

When selecting the correct adhesive, knowing the application method is key. Once you've identified the application method, you will be able to choose the right adhesive for the job. You will need an adhesives design for the application method that can adhere the type of substrate you're bonding and that has the correct set speed for your production.

Hot Melt Adhesive Testing

Before implementing a new hot melt adhesive, it's important to conduct thorough testing to ensure it meets your bonding requirements. This testing should include both mechanical and environmental testing to ensure the adhesive can withstand the rigors of your packaging application.

Mechanical testing should include testing the adhesive's shear and peel strength.

Environmental testing should include exposure to extreme temperatures, moisture, and humidity. By conducting thorough testing, you'll be able to ensure the adhesive will perform as expected in your specific application.

Hot Melt Adhesive Safety Considerations

When working with hot melt adhesives, it's important to take proper safety precautions to prevent injury or damage to equipment. Always wear appropriate personal protective equipment (PPE), including gloves and safety glasses. It's also important to follow all manufacturer instructions for use and disposal of the adhesive.

Choosing the Right Hot Melt Adhesive for Your Packaging Application

To choose the right hot melt adhesive for your packaging application, consider the following steps:

1. Determine the type of substrate you'll be bonding.

2. Consider the environmental conditions the adhesive will be exposed to.

3. Determine the speed of production.

4. Consider the cost of the adhesive.

5. Determine the application method for your specific application.

6. Conduct thorough testing to ensure the adhesive meets your bonding requirements.


By following these steps, you';ll be able to select the right hot melt adhesive for your packaging application, ensuring your products stay safe and secure throughout their journey from the factory to your customers' hands.


Common Mistakes to Avoid When Selecting Hot Melt Adhesives

When selecting a hot melt adhesive, there are several common mistakes to avoid.

These mistakes include:

  • Choosing an adhesive based solely on cost.

  • Using an adhesive that is not specifically designed for your substrate.

  • Neglecting to consider environmental conditions.

  • Neglecting to conduct thorough adhesive testing.

  • Choosing an adhesive designed for a different application method.

By avoiding these common mistakes, you'll be able to select an adhesive that performs well and meets your bonding requirements.


Selecting the right hot melt adhesive for your packaging application can be a daunting task, but by considering factors such as substrate type, environmental conditions, and production speed, you'll be able to choose an adhesive that meets your bonding requirements. It's important to conduct thorough testing and take proper safety precautions when working with hot melt adhesives. By avoiding common mistakes, you'll be able to ensure your products stay safe and secure throughout their journey from the factory to your customers' hands.
