Imagine a daily life without labels. It would be impossible to live without. Labels have so many functions. They help customers to identify products ...
Narrow web products can be used for various applications, such as self-adhesive labels, wet-glue labels, wrap-around, in-mould, tube-laminate, shrink sleeves, multiweb or pouches/sachets.
For the production of labels various printing and converting processes can be used, depending on applications and market segments.
Imagine a daily life without labels. It would be impossible to live without. Labels have so many functions. They help customers to identify products and to navigate them through life. Labelling is significant as it fetches customers’ attention to purchase the product because of visual appeal. They provide us with a range of relevant information like brand name, product details like ingredients or best-before-date, legal, logistical, security or technical information.
Narrow web products can be used for various applications such as:
- Self-adhesive labels / pressure-sensitive labels (PSA)
- Wet-glue labels
- In-mould labelling / In-mold labeling (IML)
- Multiweb (Peel-off)
- Pouches / sachets

Which are the most important label applications? Roger Oberholzer from Flexo Service explains briefly: self-adhesive labels, shrink sleeves, ROSO labels, wrap-around …
For the production of labels various printing and converting processes can be used, depending on applications and market segments, such as:
- Flexo(graphic) printing
Straightforward application and excellent process reliability make flexo printing the most widely used process in narrow web label printing.
- Offset printing
This printing process is particularly popular when top quality halftone printing and colour fidelity are required.
- Digital inkjet
The digital DoD (Drop on Demand) inkjet method is a perfect addition to high-quality flexo, offset and screen printing and is ideal for short runs of labels or individualized labels.
- Gravure printing
In gravure printing the image is engraved onto a cylinder because, like offset and flexographic printing, it uses a rotary printing press.
- Screen printing
Rotary screen printing is integrated into many narrow web presses. Screen printing equipment can work equally well in combination with letterpress printing, flexo printing, offset printing and hot foil embossing with a variety of processing functions.
- Letterpress printing
Letterpress printing is a technique of relief printing using a printing press, a process by which many copies are produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper.
- Hot foil and cold foil stamping
Foil stamping is the application of metallic or pigmented foil onto a solid surface by application of a heated die onto foil, making it permanently adhere to the surface below leaving the design of the dye.
Laminates, or composite materials as they are also known, are used in application with functional and decorative requirements.
Embossing and debossing are the processes of creating either raised or recessed relief images and designs in paper and other materials.
- Die cutting
Die cutting is the process of using a die to shear webs of low-strength materials. Die cutting can be done on either flat bet or rotary presses.
