What is the difference between self-adhesive labels, hang tags, and roll labels?

Basic definitions of the three label types

Self-adhesive labels, hang tags, and roll labels are the three most common label forms on the market. Their structures, uses, and applicable scenarios differ. Self-adhesive labels consist of three layers: face material, adhesive, and release liner; they can be peeled and applied directly, making them the most widely used label type. Hang tags refer to card-type labels attached to products, fixed with strings or plastic hooks. Roll labels are labels presented in roll form, usually containing hundreds or thousands of labels per roll, used with automatic labeling machines.

Features and uses of self-adhesive labels

The core advantage of self-adhesive labels (pressure-sensitive labels) is ease of use and strong adhesion. Face materials can be coated paper, synthetic paper, PET, PVC, etc., with adhesives divided into permanent and removable. The daily chemical industry extensively uses self-adhesive labels for bottle labeling, the logistics industry uses them for courier waybills and barcode labels. The food industry uses coated paper self-adhesive labels to indicate ingredients and shelf life information.

According to GB 4806 series standards, self-adhesive labels in direct contact with food must use adhesives that meet food contact safety requirements. Digital printing can achieve variable data (QR codes, serial numbers) on each label, suitable for anti-counterfeiting and traceability.

Features and uses of hang tags

Hang tags are usually made of white cardboard or coated paper, with a thickness of 300-400g, punched for stringing or attaching plastic clips after die-cutting. The apparel industry is the largest user of hang tags; each garment requires at least 1-2 hang tags to indicate brand LOGO, fabric composition, washing instructions, and price.

Hang tags feature rich printing processes, including hot stamping, embossing, and UV highlighting. For small-batch hang tag customization, digital printing is recommended, with no plate fees and a minimum order of 1 piece. For large batches (1000+ pieces), offset printing is more economical, with per-unit cost dropping to a few cents.

Features and uses of roll labels

Roll labels are shipped in roll form, with each label arranged at fixed intervals, used with automatic labeling machines for high-speed labeling, achieving efficiency of hundreds per minute. Roll labels typically adopt a self-adhesive structure and use flexographic or digital printing. In scenarios requiring batch labeling such as food production lines, beverage filling lines, and pharmaceutical packaging lines, roll labels are standard.

Roll labels require high die-cutting precision, and half-cut depth control directly affects labeling success rate. Experience shows that if the die-cut is too deep, it will cut through the release liner causing web breaks; if too shallow, the labels will not peel off smoothly during labeling.

Comparison summary of the three label types

Which label form to choose depends on the application scenario and production method. For scenarios requiring manual labeling and flexible quantities, choose self-adhesive labels. For scenarios that require showcasing brand image, choose hang tags. For automated production lines and high-volume labeling, choose roll labels. The three forms can also be used in combination, such as garment hang tags paired with self-adhesive price labels.
