Packaging and Flexo labels going on packaging are a very common subject at Label Tech Inc. The application of the label on a package can make all the difference when it comes to the printer's choice of materials such as face stocks, adhesives, laminates, and even varnishes. Is your packaging flexible or firm? Are you applying a label to a box, a jar, or a bag? What is the temperature of the product that we are putting the label on? These are all key elements in determining what materials and adhesives we will be printing on. A company that truly knows their product should be able to answer all of these questions with ease. Now let's dive a little deeper into this subject.
Typically, if we are talking about packaging and labeling, we need to discuss the preparation, transport, warehousing, sale, and end use of your product. All of this information is relevant to your business and to your label company. For instance, a label may appear to have enough protection with a simple UV Varnish on it, but if it is shipping across country with no dividers in the box separating the product the varnish may wear and cause your label to de-face. On the other hand, if your product is going to be labeled for use in a freezer then you may want to consider using a freezer grade adhesive. If you were to use a simple permanent adhesive then the label would most likely fall off of your product. If you are labeling in a freezer and then the product is going to be put in a room temperature environment then you definitely are going to want to laminate it to prevent condensation from ruining your label. Removable adhesives are popular for putting a label on a product that you want the customer to be able to easily remove- didn't see that one coming huh!? If you are going to be machine applying labels and want the ability to peel a label off that goes on crooked and then put it back on straight then you may want to consider using a "re-positionable" adhesive.
There are many face stocks and adhesives that can be mixed and matched based on the specific need your product has. When you are choosing a commercial printer you should try to find one that has a good working relationship with their stock supplier. This can mean all the difference if you have a special label application need. The printer can easily bring in their supplier to ensure your label is going to stick how you need it to.
Other things to take in to consideration can be simply overlooked and cause big problems later for your product's label identity. For example, if your label is going to be exposed to extreme heat at some point in it's lifetime then your printer is going to need to know. An example of this type of label could be something that is going on a furnace or hot water heater. There are many things to take into consideration when talking to your printer about your label. If you are lucky, then you will stumble upon a printer with employees that are already in the know about what questions to ask about application. Who knows, the printer you are looking for may be right under your nose!
