Pressure sensitive adhesives (PSAs) are a convenient option for your packaging strategy when it comes to sealing your products inside their parcels. They are adhered using the pressure of application, which means there’s no need for solvents, water, or heat to make them work. PSAs can be used on a variety of materials, including paper, glass, wood, plastic, or metal. They are inherently tacky and eliminate the need for surface refinishing or mechanical fasteners.

There are three main types of pressure sensitive adhesives, which are: rubber, acrylic, and silicone. Keep reading to see a quick overview of each of these adhesive options.

Rubber adhesives can be made from natural or synthetic rubbers. These are the most cost-efficient option for your company, and they present quick stick capabilities. They work well in a variety of situations but are not recommended for high-temperature applications. Rubber adhesives function well on both smooth and rough surfaces.

Acrylic adhesives are formed with acrylic polymers, which can be classified as plastic. These types of adhesives are resistant to sunlight and UV rays, and their bonds are not easily broken by water or humidity. Acrylic adhesives are also able to withstand temperature fluctuations, making them useful in a number of industries.

Silicone adhesives are formed with silicone polymers and are the only option when working with other silicone substrates. These types of adhesives provide exceptionally high heat resistance, which makes them a good option for the electronics, aerospace and automotive industries. They can be priced higher than the other two options listed above, and they will also present a low initial tack at first contact. Silicone adhesives can migrate, which means there can be adhesion left on the application surface.

Now that you have a basic overview of these three pressure sensitive adhesives, you can predict the needs of your business and make the right packaging decisions.
