If your label does not stick to the container immediately or lifts off after some time, consider these solutions:
Label Stock Adhesive. All of Primera's label stock has Acrylic based adhesive. Most of it has the same adhesive strength. Each label type has its own spec sheet that details the exact type of adhesive. You can find spec sheets below. However, we do make Premium Gloss Paper stock in three different levels of adhesive strength.
High Gloss Paper Removable is a low-tack adhesive meant for removable applications with an adhesive similar to a sticky note.
Premium Gloss Paper has standard adhesive,
and
High Gloss Paper Super Sticky is our strongest adhesive. They are available for
custom order in any size or shape.
Container / PackageType. After the adhesive cures, it forms a chemical bond between the adhesive and the containers. For this reason, the strength of the bond can vary between different container material types depending on the material type, texture and smoothness of the surface. Glass. Most adhesive sticks to glass very well but the process to create glass does not always produce a smooth surface. Ripples or bumps in the surface can negatively affect the strength of the adhesive bond. Plastic. There are many types of plastic used for containers. While they are generally more smooth than glass, each has its own chemical properties. The particular plastic in your containers may not be compatible with the adhesive in the label stock. Check with your container provider on options for different plastic materials. Paper boxes or Bag. Our adhesives stick very well to these products. However, if you are applying labels to bags it is critical to ensure that the bag is completely smooth before applying the label.
Application Environment. Make sure the surface is clean and free of oil, dust, or product before applying labels. Follow application temperature guidelines in the spec sheet for your material.
Cure Time. Let the adhesive cure for 24 hours before freezing or heating the container beyond optimal application temperatures.
Container diameter. Smaller diameter containers have a tight curve or radius which can affect the adhesive bond. The labels have some "memory" so they want to go back to their storage state on the roll which is curved but probably a lot less curve than a small container. This is why the labels lift over time, especially on smaller containers. Two things can help with this. 1. Overlap. Purchase labels that are slightly longer so that they overlap when they apply to your container. The adhesive always sticks better to the top surface of the label than it will to the container. 2. Pressure. After application immediately place the containers in a box or storage bin so that the containers are tightly packed together. This extra pressure especially during the first 24 hours of curing can help press the label onto the container. After the curing time feel free to pack the labels for shipment or display as you normally would.
Press the Edges after application. Immediately after application, press the label onto the container, especially at the edges. This ensures that every part of the adhesive is contacting the container. Often labels don't stick because the label was lightly applied and not enough adhesive was in contact with the container.
Storage environment. Follow Service temperature range guidelines in the specifications sheet.
