Self-adhesive labels and stickers are certainly among the most frequently printed products!

 

Self-adhesive labels are versatile tools that simplify labeling, identification, and organization of various objects and surfaces in numerous industrial and everyday applications.

Labeling materials have adhesive on the backside, allowing them to be applied to various surfaces and products. Due to their ease of use and wide applicability, labels are an extremely popular and irreplaceable print product used for a variety of purposes, such as product labeling, promotions, safety information, parcel markings, packaging, bottle labeling, pharmaceuticals, cleaning products, and many other applications.

Labels are usually printed with text, images, or other symbols (QR, EAN...), which help convey specific data about the item to which they are attached, providing essential information about the product, item, packaging, or other surfaces.

Despite differences, the terms "label" and "sticker" are often used interchangeably, so it is important to understand that both terms are related to the use of adhesive on various surfaces.

Stickers can be used for the same purposes as labels but often refer to labels with a more decorative or promotional function, such as stickers for vehicles, glass surface decorations, outdoor information stickers...

It should be emphasized that different materials are used to produce these types of stickers, as well as different printing technologies, which can generally be categorized as large format or XXL printing (UV, Latex, Solvent, Eco-solvent printers...).

Self-adhesive labels are typically more functional and serve practical purposes, such as providing product information, marking, identification, or organization. Because labels are usually small in size, they require appropriate printing technology that allows for high-resolution printing so that important information on the small label is sharp and visible. Additionally, the selection of label materials is significantly broader, offering a variety of adhesive and printing material choices.

In Demago Print, we can offer both label and sticker printing, as in both cases, we use modern technology and self-adhesive materials that ensure uncompromising print quality (HP Indigo). We can print from sheets sized 500x700 mm (Cut-sheet) or from rolls with a width of 33 cm and length of 2000 m (Roll to Roll).

Based on the chosen printing technology, the final product can be either a sticker or a label. If the self-adhesive material is printed from a sheet, the final product is a sticker; if printed from a roll to roll, the final product is a label.

Since the purpose of using labels is very broad and they are practically used in all sectors of industry, it is essential to follow certain criteria when selecting the correct label, based on which we can properly decide which type of print, material choice, and finishing is most appropriate.

During the determination phase, obtaining information about the label's intended purpose, potential legal regulations related to its use, the product's lifespan, labeling conditions, primary product packaging... is crucial.

We understand that not everyone is an expert in this field and that you may be ordering labels for your products for the first time, so we will try to present the basic characteristics of self-adhesive labels and printing materials in a few sentences.

We recommend that you read a short description about printing technologies, finishing, and materials before making a purchase, as this will help you select the optimal label for your next project more quickly and easily.

Label Printing Materials

 

Self-adhesive label materials are specially designed materials that are coated with adhesive on the backside, intended to enable easy adhesion to various product surfaces, packaging, documents...



Label printing materials
Label printing materials can generally be divided into two main groups: self-adhesive paper materials and synthetic materials.


1. Paper Materials:

Coated papers - for printing high-quality labels that require excellent contrast and fine details.

Thermo-sensitive papers - coated paper suitable for thermal printers, e.g., for printing variable data, declarations, weight labels...

Metallic papers - for achieving special visual effects or as a substitute for gold printing.

Design papers - specialty papers with special textures or color nuances, intended for wine or beer label printing...

Fluorescent papers - specialty papers in neon colors that attract attention, intended for marking products, sale prices...


2. Synthetic Materials:

PP or BOPP - Polypropylene - durable, long-lasting, slightly stretchable, and water-resistant material for various applications. Available in white, metallic silver, and transparent.

PETP - Polyester - extremely durable material, resistant to moisture, oils, chemicals, and high temperatures, making it ideal for long-lasting indoor and outdoor applications.

 




Types of Adhesives

 

Adhesives for label materials differ in their characteristics and properties, and they are chosen based on the material of the label, the surface to which the label will be applied, usage conditions, and other factors.

The type of adhesive used for self-adhesive label materials is critical, as it influences the adhesion strength, durability, and suitability for a particular application.

The adhesive is applied to the base material, chosen based on the substrate the labels will be applied to, as well as environmental conditions during application, storage, and use.

If the adhesive is improperly chosen, labels may curl or even detach from the surface, or they may be difficult to remove when required. Therefore, we recommend being attentive when selecting the adhesive.

Types of adhesives for labels
Types of Adhesives:

• Permanent Adhesive - standard acrylic water-based adhesive for bonding to most substrates. The adhesive is durable, water-resistant, and performs well at low temperatures.

• Hot Melt / Extra Permanent Adhesive
- strong permanent adhesive based on rubber, providing very high initial tack. The adhesive is durable, water-resistant, and performs well at low temperatures.

• Removable Adhesive
- easy-to-remove adhesive, where easy removal of labels is required without leaving adhesive residue.

• Deepfreeze Adhesive
- a special type of adhesive that allows bonding to frozen products (down to -10°C).

• Cover Up Adhesive
- special black or gray adhesive designed for covering or relabeling.

 




Die-Cutting Labels: Die Cut or CNC Cut?

 

Die-cutting labels is a key finishing process that defines the final shape or dimension of a label, separating it from the substrate. Labels are most often standard shapes, such as rectangular or circular, but can also be irregular shapes upon request.

Classic Die-Cutting (Die-Cut) is performed on a rotary die-cutting machine using a cutting tool or magnetic die, which, through pressure, cuts or scores the self-adhesive material into the final shape.

The process then involves separating the waste material (matrix), cross-cutting, and rewinding the labels onto rolls of the appropriate width. Since it is a modular machine, labels can also be varnished or laminated.

The biggest advantage of die-cutting with a cutting tool is the speed of the machine, making this method ideal for print runs of at least 500 pieces or more.

Digital Label Cutting (CNC-Cut)

 

Digital label cutting (CNC-Cut) is a digital process that cuts labels without the need for a cutting tool or die, instead using cutting blades mounted in heads that are computer-controlled and use an optical camera to detect markers, allowing for extremely precise cuts.

The process then involves separating the waste material (matrix), cross-cutting, and rewinding the labels onto rolls of the appropriate width. Since it is a modular machine, labels can also be laminated.

The biggest advantage of digital cutting technology is the ability to cut labels in any size and shape without the need for cutting tools, eliminating the cost of making cutting dies.

Compared to classic die-cutting, this finishing method is slower, so it is suitable for label quantities of 100-5000 pieces.

Machine or Manual Label Application?

 

Labels on rolls are an important element in industrial labeling and are commonly used for product labeling, packaging, and other applications where automated and continuous labeling is required.

Since labels are supplied on large rolls, they ensure uninterrupted supply and smooth operation of the labeling machine. Machine label application is commonly used in the food, pharmaceutical, cosmetic, packaging, logistics, and many other industries.

The advantages of machine label application include increased production efficiency, greater accuracy, and faster processing of large quantities of products. This is especially important in environments with high production capacity, where manual label application is impractical or inefficient.

When opting for machine label application, it is important to pay attention to the correct selection of label position on the roll (label width in the cross direction and label length in the longitudinal direction), label orientation on the roll (A1 - A8), the internal core diameter of the roll (25, 40, 76 mm), the maximum outer diameter of the roll, the number of labels on the roll, and the gap between labels in the longitudinal direction...

For manual label application, the data on label direction and position on the roll are not important, as the application of labels to products is done without the use of special equipment or machines.

Labels for manual application can be supplied on rolls or spools in label width, on a 33 cm wide roll (Roll to roll), or in sheets of approximately 30x33 cm (Roll to sheet).
