Label construction could be one of the last things you think about when you finalize your product packaging. A lot of thought goes into creating a label that is best suited for your product, how the consumer will use the product, and the packaging environment — especially when it comes to pressure sensitive labels.
Before you have a label printed for your product, you need to consider a number of factors. The following are some questions you should be able to answer before choosing the best pressure sensitive label.
Take a Close Look at the Container
Although an obvious step, you need to carefully analyze the type of container you use for the product. Is it made of plastic, glass, or cardboard? Is the cardboard recycled or new? Is the plastic made from resin? Is the container flexible or can it be squeezed?
Each type of container will have unique factors that help determine the type of label you need. Different containers require different cutting and sizing requirements to remain on the product throughout its lifecycle.
You also need to consider the composition of the container. The shape and the structure of the surface is important to the type of label required. Is the shape round, curved, straight, or a combination of different shapes? Is the surface smooth, rigid, or glossy? The adhesive chosen for your container will highly depend on these factors to ensure the label adheres properly.
Consider the Application Process
The next thing you need to consider is how the label is applied to the container. What type of line is the label application in? Is the line rotary or linear? Is the label directly transferred, blown on, or tamped on the container? What speed is your applicator running? Some labels need a slower application time than others to ensure they adhere to the container.
The next thing to look at is the environment of the applicator. Is the air damp or humid? Is the temperature hot or cold? What is the temperature in your storage area? Does your facility contain any contaminates, such as oils, powders, or other liquids, which could impact the capability of the labels?
Certain adhesives have properties which do not mix with certain solvents and other materials. Knowing which ones your product will have contact with will help determine how the label is applied to the container.
Will your product go through a sterilization process before going to the store shelves? Is there any chance the label and container will get wet during the application process? Certain labels will not remain on the product in wet environments. The printing on the label could also become muddled and illegible, which is not what you want to provide your customers.
Consider Where Your Product Will End Up
Once you have a good idea of the application process, the next factor to consider is where the product will end up in the store. Will the container and label require refrigeration or time in a freezer? Does your product consist of any product which will have an impact on your label should the product leak out?
Is there the possibility the container will have contact with any solvents, chemicals, major temperature shifts, or abrasion? Is the product for indoor or outdoor use? Are you required to meet any type of compliance terms? All of these questions will help determine which adhesive, paper, and other label components you place on your product.
Keeping these factors in mind will help determine if the pressure sensitive label will last throughout the life of your product. You do not want to provide a faulty label to your customers.
A pressure sensitive label is made of different coatings, liners, and adhesives. There is no one way to construct a label specific to each product on the market.
