Cosmetics Labelling — Label Types, Application Methods, and Batch Coding

Labelling is where a filled and capped product becomes a branded product. It is also one of the production steps with the most variables — label material, finish, shape, application method, and batch coding all affect the final result and require specific equipment and setup. Understanding how cosmetics labelling works helps you design labels that will apply cleanly, code correctly, and present consistently on shelf.

The main label types in cosmetics

Cosmetics use several distinct label types, each suited to different container shapes and product positions. Round bottle labels — also called wraparound or roll-feed labels — wrap around cylindrical bottles. They are applied by rotary labelling machines and are the most common label type for perfume bottles, serum bottles, body lotion bottles, and other cylindrical containers. Flat bottle labels — applied to flat or oval containers, bottles with flat front panels, or tubes. Applied by flat bed labelling machines or by hand for smaller production runs. Front and back labels — two separate labels, one on each face of the container. Common for larger bottles, body care products, and products where the front face carries the brand design and the back panel carries the ingredient list and regulatory information. Cap labels — labels applied to the top or side face of a cap. Used for identification, batch coding, or branding. Common on perfume caps, jar lids, and tube caps. Tamper-evident labels — applied across the cap and bottle neck to indicate if the product has been opened. Required for some product types and retail channels.

Label materials and finishes

The label material affects both the visual result and the durability of the label in use. Paper labels — the most economical option, suitable for products stored in dry conditions. Paper labels are susceptible to moisture damage and are not suitable for products that will be used in wet environments (shower gels, bath products) without a protective overlaminate. White or clear BOPP (polypropylene) labels — a plastic film label that is water-resistant, more durable than paper, and available in gloss, satin, or matt finishes. Clear BOPP labels on a clear bottle create a ‘no-label look’ that is popular for premium skincare. White BOPP labels have excellent ink adhesion and are the standard choice for most cosmetics. Metallised labels — chrome or gold metallic effect, applied to paper or film base. Popular for luxury fragrance and premium positioning. Textured and specialty materials — linen-effect, velvet laminate, soft-touch coatings — available from specialist label printers for premium packaging. The label material and finish must be agreed with your label printer before artwork is finalised, as different materials have different print specifications and application characteristics.

Label application — machine vs hand

Labels are applied either by automatic labelling machine or by hand. Automatic labelling machines apply labels at speed with consistent positioning. They are calibrated for specific container dimensions and label dimensions, and require changeover time when switching between container types. Automatic application is cost-effective for medium and large batches and produces very consistent label positioning. Hand labelling is used for small batches, unusual container shapes that cannot run on standard machines, and specialist packaging. It is more labour-intensive and produces less consistent positioning than machine application, but requires no minimum batch size and no machine setup. For most cosmetics operations, automatic labelling is the norm for any batch above a few hundred units. Confirm with your manufacturer whether your container is suitable for automatic labelling and what the minimum batch for their labelling machines is.

Label registration — getting positioning right

Label registration refers to the accuracy of label positioning on the container. On a cylindrical bottle, the label should start and end at exactly the same point on every unit; the top edge should be consistent across all bottles; and if there are front and back labels, they should be positioned symmetrically. Poor label registration — wonky labels, inconsistent heights, labels wrapping over onto the bottle base or neck — is one of the most visible quality defects in finished cosmetics. Good label registration requires: containers that are dimensionally consistent (minimal variation in diameter and height); labels that are consistent in their printed dimensions; correctly calibrated labelling machines with appropriate guides and sensors; and regular in-process checks during production. If your container has a particularly challenging shape — tall and narrow, with embossing or surface texture, or with a complex neck profile — test a small sample run before committing to full production.

Batch coding and lot number application

Every cosmetics batch must carry a batch number (lot number) that enables traceability back to the manufacturing record. In addition, products may carry a best-before date or PAO indication, a manufacturing date, or other variable information that changes batch by batch. This variable information cannot be pre-printed on labels because it changes with every production run. It is applied by batch coding equipment as part of the production process. Common batch coding methods include: inkjet coding — a non-contact method that prints directly onto the container or label surface using fast-drying inks. The most common method in cosmetics production. Can print on glass, metal, plastic, and most label materials. Laser coding — uses a laser to mark directly into the surface of the container or label. Produces a permanent, high-quality mark that cannot be rubbed off. More expensive than inkjet but preferred for premium fragrance and cosmetics. Thermal transfer coding — applies code via a heated ribbon, commonly used on pouches and flexible packaging. Hot stamp coding — applies code via a heated die, used on some aluminium tubes and closures. Agree the coding method and the information to be coded with your manufacturer before production. Provide your batch number allocation system — or ask the manufacturer to assign batch numbers according to their system — so that records are consistent.

Cap labelling

Cap labels require specific equipment — typically a top labelling machine or a cap labeller — and present some challenges that body labels do not. Caps are often uneven in diameter (tapered) or have raised features that affect label adhesion. Cap labels must be sized to fit the cap face without overhang that would interfere with closure function. The label material must adhere securely to the cap material — metal caps, wooden caps, and plastic caps all have different surface characteristics. If your product uses cap labels for brand identification, batch coding, or tamper evidence, confirm that your manufacturer has the equipment and experience to apply them to your specific cap type before production.

What to prepare for a labelling production run

To ensure your labelling run goes smoothly, prepare: label artwork finalised and approved — artwork changes after labels are printed create waste cost; label specifications — material, size, finish, adhesive type, core size for machine compatibility; container specifications — dimensions, surface material, any features that affect label application; batch coding information — batch number, date format, information to be coded and where; labelling position specification — distance from base, from neck, gap between front and back labels; and sample containers for machine setup before production begins.
