Topcoat for product labels: laminate vs. Varnish

While planning for custom product labeling, your packaging supplier may ask you to choose between laminate and varnish topcoat. It is necessary to understand the difference between both if you want to choose the right option.

The role of a label topcoat

There are multiple layers of materials used in the making of product labels. The first thing coming into the mind while thinking of product label materials is the face stock, which is a label onto which you have to print an image or design. It means that the appearance and performance of a label depend on this layer. That is why you have to choose this material quite carefully. There is another layer that is just as important as the face stock because it determines the feel, looks, and lifespan of a label.

The top layer of the label is known as a topcoat, which adds protection to a label. This layer deflects damage and scuffling. This layer also influences the feel and look of a finished label. The two material options that you can choose from are varnish and laminate.

Is there a need for a topcoat for a product label?

A topcoat layer is not required for the finishing of product labels. The purpose of this layer is to protect the packaging design. The absence of a topcoat layer results in ink from the unprotected face stock surface wearing off. It also results in the product label getting exposed to moisture, liquids, oil, dust, and other factors.

Varnish topcoat

This topcoat consists of a silicon-based liquid covering a printed label. These topcoats are ideal for indoor use labels. These topcoats are not much resistant to moisture and are more prone to the impact of scuffing and smudging.

Varnish topcoats are usually available in matte, gloss, and satin finishes. They provide only basic protection to everyday product labels.

The varnish techniques used for label protection are the following.

• Flood coat: This technique results in the topcoat covering the entire product label because it flows to the edges of the face stock and printed images.
• Spot varnish: This topcoat covers only a part or parts of the image or face stock. This layer maximizes the contrast between gloss and matte surfaces.
• Dimensional varnish: This varnish involves the use of several layers to give a label some dimensional qualities. It is a way to create textures without embossing or de-bossing.

Laminate topcoat

This topcoat involves the application of a film, typically made of polyester. It serves as a plastic barrier that keeps the face stock well-protected. These topcoats are more effective in preventing damage from moisture, oils, UV, scuffs, and smudges.

These topcoats come in both glossy and matte finishes. They also prevent a label from the impact of thermal transfer during secondary printing.

You can discuss with your packaging supplier the type of topcoat you can use for your product labels. First and foremost, you will need to look at your labeling requirements. It will help you select the best quality topcoat according to your needs.
