FAQs On Applying Labels & Sleeves

« All Topics

  • Hand applying a label
    What type of adhesive works best for my labels?

    It’s important to understand what type of label adhesives are available and how they differ. Within the pressure-sensitive adhesive category, there are three main classifications: permanent, removable, and repositionable.

  • Label for product pasteurization
    How do I label products that will be hot-filled or pasteurized?

    A label material we use often for these types of products is white pearlescent polypropylene, a semi-conformable film. Often, high-pressure processing is used in place of heat pasteurization for juices and we also have labels that can be used with this process, such as white BOPP film with UV gloss lamination which has excellent moisture resistance.

  • Label adhesives for different surfaces
    Why do label adhesives perform differently on different surfaces?

    Label adhesives are available in different strengths but there are factors outside of the adhesive that can affect its performance – in particular, the surface that the adhesive comes into contact with is crucial to how it will perform. Why label adhesives perform differently on different surfaces is due to the composition, texture, shape, cleanliness, and temperature of the surface.

  • How microwaves and ovens affect label adhesives
    Can adhesives be used in the microwave or oven?

    Pressure sensitive adhesives (aka ‘self-stick’ adhesives that don’t require solvents or heat to activate the adhesive) shouldn’t be used in the oven or microwave for a couple of reasons.

  • Shelf life of labels vs service life
    What is the shelf life of labels?

    If your labels will be used for a short period of time, such as within six months, the majority of label materials will work for your application. On the other hand, if your labels will be outside, or face extreme conditions (freezing temperature, chemical exposure, etc.), or need to last for years, then it’s important to let us know so we can select a label material with a service life that fits your labeling needs.

  • Label curling up
    Why is my label curling up?

    There are several possibilities that can explain why your label is curling up, fortunately, most of them are relatively easy fixes: your label material may be too thick or stiff, your container shape is tricky to label, you’re not using a permanent label adhesive, or your label has square corners.

  • Label not sticking
    Why is my label not sticking?

    If you’re running into the issue of your label not sticking to the container or application surface, there are several reasons why this is happening and what you can do to fix it. Variables like container cleanliness, texture, shape, temperature, and environment can affect how well your adhesive works.

  • Bottle flaming treatment
    What is bottle flaming?

    Bottle flaming is an in-line surface treatment for caps, bottles, and lids to ensure that labels will not peel off before the label comes to the end of its lifespan. This treatment is used for bottle materials that are “chemically inert” and won’t bond with glue.

  • Type of labeling equipment
    What type of labeling equipment should I use for my labels?

    Hand applying labels is an easy and affordable method but it isn’t exactly practical for applying large label quantities. If you’ve done any research into labeling equipment, you’ll find that suppliers offer different equipment types according to price, container abilities, speeds, configurations, and more. Before you buy anything, it’s helpful to learn your options to help you make a more informed purchase decision.

  • Apply shrink sleeves
    Can I use a blow dryer or heat gun to apply shrink sleeves?

    We don’t recommend applying shrink sleeves with a blow dryer, heat gun, microwave, or shrink wrap tunnel because shrink sleeves need to be applied with a uniform spread of heat.
