Published

on

Custom food labels are a great way to add appeal and personality to your food packaging. However, all the hard work in food label printing will be in vain if you do not choose the right adhesive. For instance, what if the label falls off during transit, and the consumer doesn’t know whether or not it is within the consumption timeline? It will create trust issues among the customers, and they will cease the purchase. Therefore, always be wary of the adhesive on your food label. 

We’ll review the different types of adhesives available and help you determine the best for your needs. Keep reading-

What Is a Label Adhesive?

Label adhesive is a type of adhesive used to attach labels to surfaces. Companies can use it on various surfaces, including paper, plastic, and metal. Different food label adhesives exist, and one can choose the best one depending on the requirement.

What Are the Different Types of Adhesives?

By adhesive, you may envision that it must be something that firmly holds the label onto the package. Though it’s partially correct, one must understand that label adhesives are available in different types depending on their characteristics. Before are a few types of food label printing adhesives and their unique features-

Pressure Sensitive Adhesives

The most common type of adhesive in food label printers is a pressure-sensitive adhesive (PSA). Food brands can use this adhesive on nonporous surfaces such as glass and metal. It features high tack properties, so it sticks well onto the surface with little pressure. However, PSA does not have much resistance to water or moisture. Therefore, it can easily slip and fall off the package if it gets wet. It’s recommended not to use pressure-sensitive adhesives on a food product suspected to come into contact with liquids. 

Permanent Adhesives

Another popular option is a permanent adhesive. These usually feature higher strength than PSA adhesives and generally provide better resistance to moisture and other environmental conditions. Permanent adhesives are often on paper labels or plastic film, but they can also be applied directly onto some materials, such as glass or metal containers. 

Removable Adhesives

The next category is the removable adhesives that offer good shelf life but are easily removable when necessary. These types of adhesives feature a weaker bond than permanent or pressure-sensitive adhesives. Hence, they are ideal for applications where the package requires easily removable labels without damaging the surface underneath. Removable adhesive labels are handy in restaurants where there is a need to change them quickly due to menu changes or other factors. 

Freeze-Grade Adhesives

A freezer-grade type of label adhesive is a type of adhesive that can withstand temperatures as low as -40°C and remain firmly and securely attached to a surface. It is a strong and durable polymer that can withstand extreme cold without breaking down or losing its bonding power. This adhesive is often used on labels and packaging materials in the food industries, as it can maintain a strong bond even at extremely low temperatures. Some examples of freezer-grade label adhesives include acrylic, rubber, and silicone-based adhesives.

Repositionable Labels

As the name suggests, a repositionable label is easily removable from one package and attachable to another. It also doesn’t leave residue or damage the surface. It is common as a temporary labelling or for labels that need to be removed and reapplied frequently, such as in a retail or office setting. Some common types of repositionable adhesives include removable glue dots, pressure-sensitive adhesives, and static cling adhesives.

Things to Consider When Choosing Adhesive for Your Food Labels

Adhesives are a vital element of food labels. Therefore, brands are highly cautious when choosing adhesives. There are multiple elements to consider when selecting an adhesive for food labels. Below are a few of the crucial points one must consider before determining the right adhesive for labels-

  1. Compatibility with the label material: The adhesive should be compatible with the label material to ensure that it adheres properly and does not cause any damage.

  2. Temperature tolerance: If the retailer or distributor requires you to store the food at a specific temperature, you must ensure that the adhesive doesn’t fall off in such storage conditions. It must be able to withstand the temperature in different situations.

  3. Resistance to moisture and humidity: Sometimes, a food package has moisture over it due to saturation. In such a situation, there are chances that the label will fall off if you use the wrong adhesive. Therefore, choose an adhesive resistant to these conditions to prevent the label from peeling or falling off.

  4. Chemical resistance: The adhesive should be resistant to chemicals that may come into contact with the label, such as cleaning agents or food additives.

  5. Ease of removal: If the label needs to be removed, the adhesive should allow for easy removal without leaving any residue or causing damage to the container or packaging.

  6. Cost: Consider the cost of the adhesive and ensure that it fits within your budget.

Summing Up

Whether you’re labelling jars, cans, bottles or boxes, selecting the suitable adhesive for your food labels will ensure that your labels stay put until you’re ready to take them off. With an understanding of the different types of adhesives available and their strengths and weaknesses, you can ensure that whatever label material you choose will work perfectly for your product packaging needs.
