Types of Label Adhesives 

To choose the right adhesive for your label, it helps to know a little about them. Label adhesives exist in four main categories: 

1. Permanent Adhesive. This type of label adhesive is essentially impossible to remove without damaging or distorting the label to which it is applied. Choosing the right type of permanent adhesive requires considering the amount of UV exposure, moisture levels, temperature range, substrate, and the surface material of the product. For example, a label for a small vial would require different permanent adhesive than a medical device which goes through sterilization.
2. Removable Adhesive. This type of label adhesive leaves behind little to no residue when removed. Removable adhesive is designed for temporary use and not to damage the substrate when removed.
3. Repositionable Adhesives. These label adhesives are ideal for removing and reusing labels from products, such as large products that need flat, even application. Removable labels allow end users to place labels exactly as needed. Sticky notes are a common example of a product that relies on repositionable adhesives.
4. Temperature-Specific Adhesive. These label adhesives are ideal for difficult label applications. If a label needs to be straightened out or a crease or bubble removed. Repositionable adhesive is also widely used in applications such as baby wipes, wet wipes, and makeup wipes.

Once you have narrowed down the type of label and label adhesive a product will require, break down each option's performance factors to find the ideal type. 


Rubber Vs. Acrylic Adhesives

Now, a label adhesive can made be made from one of two things. Rubber or acrylic. Rubber-based adhesives are great for the long-term. If your product is housed in a plastic container, then these are your go-to. Just make sure the plastic container itself is stored in a reasonable room temperature environment. See, most rubber adhesives tend to lose their stickiness when made to endure really cold or really warm temperatures. Speaking of warmness, exposure to direct sunlight can also reduce the label's ability to stick. If you have a product that is not meant to be left outside, or stored in extreme temperature conditions then you'll want to give rubber adhesives a try. Otherwise, consider acrylic adhesives. Acrylic adhesive is made with the capacity to endure a wider range of temperatures. It can take on direct sunlight without losing any of its stickiness. It has difficulty clinging to plastic or other low surface-tension surfaces, but will adhere to most other containers and items with ease, and for a long time too.
