What is a pressure sensitive label? Are they stickers,
product identifiers, decals or a component of decorative packaging? Yes! Pressure-sensitive labels are used everywhere
from toys, food bottles, medical devices, and corrugated boxes, to plastic
pouches and so much more.
Let's break it down: A
pressure-sensitive label, or self-adhesive label, is made up of three layers: a
face stock, an adhesive and a release liner. We refer to this as the
"label sandwich." When a label is manufactured, these three
components are sandwiched together to create a label material that can be
printed on, laminated, die-cut, and finally peeled off and applied to your
product.
Facestock: The
facestock is the main part of the label. The material could be paper, film, or
metallic foil. This is the layer where the ink is applied on press. For
specific applications, a topcoat or laminate may be applied to protect the
label artwork or enhance certain areas of the design.
Adhesive: The
adhesive is what makes the label stick to the surface of the product or
packaging. For glue-applied (cut & stack) labels, this process happens as
the label is being applied. A pressure-sensitive label is manufactured to have
the adhesive already applied to the face stock when you receive your roll or
sheet of labels.
The adhesive type will depend on your application and
environment in which the label will be used. Many different types of adhesive
are available including versions that stick under cold and wet conditions, some
that release easily, some that stick permanently and others that are
resealable.
For example, a label that is applied to a durable good, like
an air conditioner, will require an adhesive that sticks to metal in an outdoor
environment and can last for years. If the label is only going to be used once,
say for a shipping carton label, a strong adhesive isn't necessary. You might
even select an adhesive that is re-positionable for a peel and redeem coupon.
Liner: The liner is
the paper or film that makes up the backing web material. There are options
that range from semi-bleached paper or craft paper, to a stronger clear film
liner. The liner is coated with a special material that makes it possible to
remove the label no matter how strong the adhesive you select.
