Labels and stickers: the most flexible solution

Among all types of packaging, labels are the most flexible and easiest to start with. You do not need to invest in a custom mold, do not need to print in bulk to be cost-effective, and can change designs almost anytime. But fulfilling the correct role is essential to leverage that advantage. Misusing the role, labels become a setback instead of a stepping stone.

What are labels and stickers?

A label is a graphic layer attached to an existing container surface (bottle, jar, tube, box, primary packaging). A label is not a container and does not create a barrier for the product inside. The entire role of the label lies in the information and branding layer on the surface.

There are four main label groups you will encounter:

• Pressure-sensitive label: the adhesive layer sticks when pressed by hand, without the need for heat or water, adhering to flat or slightly curved surfaces such as glass bottles, plastic jars, and metal boxes. This is the most common type.
• Shrink sleeve: a plastic film that shrinks with heat, covering the entire surface 360 degrees including complex shapes. It is available with tamper-evident sealing, meaning it shows immediately if it has been opened or cut. The cost per unit is higher than pressure-sensitive labels and requires heating equipment at the labeling facility.
• Wet glue labels: use water-based adhesive, compatible with high-speed production lines, most economical for very large batches like beer and beverages.
• In-mold labels: attached to the item during the blowing or injection molding process, cannot be removed, only used for plastic containers produced in that manner.

The label surface can be made of regular paper, art paper, plastic film, or metallic foil. Additional processing like foil stamping, embossing, or localized UV coating can enhance the premium feel. For anti-counterfeiting labels, holograms (three-dimensional images that diffract light), QR codes, microtext, UV-reactive ink, or VOID labels that leave a mark when removed can be integrated.

When to choose, when not to

The most suitable label in the following situations:

• Market testing: label containers in stock to gauge feedback before investing in cohesive printed packaging.
• Customizing common containers: using the same type of bottle or jar purchased off the shelf, with different labels for each product or line without needing a separate mold.
• Small batches with frequent design changes: low setup costs, design changes are not as expensive as offset printing in large quantities.
• Goods need anti-counterfeiting and traceability: integrate QR codes, GS1 standard DataMatrix, holograms, or VOID labels.
• You need to seal the original: shrink wrap is a more economical choice compared to upgrading the entire container.
• B2B channels like roasted coffee: 1 kg bags as common containers, labeled with the blend name and roasting date for each order.

Do not use labels in the following three cases. First, an official launch in the premium segment requires seamless packaging: labels applied to ordinary containers often do not achieve the seamless feel that segment demands. Second, products needing moisture or gas barriers: this is the role of the container, not the label. Third, complex curved surfaces when only using flat pressure labels: in that case, consider shrink film.

Costs, time and quantity

Regarding product labeling, Decree 43/2017/ND-CP stipulates mandatory content on labels: product name, quantity, origin, and additional requirements depending on the industry. For example, cosmetics must list ingredients according to INCI nomenclature, and functional foods must include mandatory warning lines. This compliance section needs to be reviewed by a packaging legal expert to ensure it meets the terms and checks font height before printing.

Sinh Vũ is responsible for designing label structure, graphics, and technical files for print. Sinh Vũ does not guarantee printing prices as they depend on the printer, quantity, label surface, and finishing you choose.

What does Sinh Vũ need from you to get started

To allow Sinh Vũ to advise on the right type of label and provide appropriate design direction, you need to provide:

• Container type: Bottle, jar, tube, box, or any surface, material, and shape. Having a real sample container makes it clearer.
• SKU number (unique product code): A type of label or multiple versions, whether flavor, volume, or product line differentiation is needed.
• Market and sales channels: domestic or export, online, modern retail, or corporate. Export markets may entail specific language and compliance requirements.
• Usage objective: market testing, official launch, anti-counterfeiting, sealing, or replacing old labels.
• Industry compliance requirements: Cosmetics, food, pharmaceuticals, or other sectors. Each industry has different labeling regulations.
• Guided budget and timeline: an exact number is not needed right away, but knowing the range helps Sinh Vũ propose the correct printing techniques and label specifications.

When you have clarified the above points, the next step is to send information to Sinh Vũ to begin discussions. Sinh Vũ will confirm the appropriate label type, production orientation, and the list of content that needs to be prepared before moving into design.
