The Label
Technically, the label is built from separate layers;
Front Material is the area where information such as pictures, text or bar codes are printed.
Adhesive depends on for what purpuse the label is intended, but is divided into two mayor groups, permanent and removable.
Liner is the label carrier, with a special surface to make the label easy to lift.
Whether the label is intended for branding, security, logistics or something else, we can offer a variety of combinations from the three parts mentions above, with a high technical and quality level.
One of our core business areas is labels with more than one printable layers. It may be a dual label, where the top layer is removable and printed on the adhesive side aswell as on the base layer, meaning three printed pages that can be used for example for table of contents in several languages.
Booklet labels with up to 64 pages are produced inhouse at Jigraf. An application example is on-pack promotions where large information contents can be applied directly on the consumer goods.
Label Material
The front materials can be provided with several different qualities. Paper based materials are mainly used in less demanding environments. Most common synthetics are Polyethylen (PE) and Polyprophen (PP), often used on packaging in the same material. Polyester (PET), Polyamid and Polyuretan are other types of materials, often used for labelling in more demanding environments.
Material resistant against high temperatures are also available, peelable or non-peelable.
Printable materials are divided into thermal, thermal transfer or laser printable.
Different material thickness give different characteristics, a thinner material is preffered for labelling a curved surface, while a thicker may be preferred in a rough environment.
Application
The application can be made by hand for by a machine.
For best result the combination of surface, adhesive and applicator should be optimized. We are happy to assist in these matters.
There are five application alternatives, side, top, bottom, around or around corners.
Check List
As a guide, we have put together a check list:
-
What is the purpose of the label?
Information, sales promotion, image creating, functional, product identification, security?
-
Where will it be applicated?
Container type? Metal, glass, well, wood, painted surface, plastics (what kind, i.e. PE, PP, OPP). Inside or outside. Characteristics of the surface? Handling specification.
-
In what environment will the label be applicated?
Temperature/moist, environment (outside/inside). Water resistant. Before or after filling.
-
What will it be exposed to?
Water, fat, acid, solutions, heat or cold, UV exposure, physical wearing, customer specific tests, transport etc.
-
For how long will it stick?
Days, months, years? Life time requirements, light resistans.
-
Permanent?
…or removable? Container surface. If removable, washable, water soulable? No residues? Security features?
-
Additional information on the label?
Text or barcode? By hand or printer and if so, what kind of device and what technique, thermal / transfer / laser? Before or after application?
-
How will the label be applicated?
Manually, semi- or fully automatic? Air fastened or by mechanical pressure. Environment?
-
Design regulations?
Type of SEMKO-, UL- or CSA-demands for instance, or perhaps customer specific tests? Specifications depending on labelling environment, for example if applied on food it is essential that ink and varnish is of non odour type, EN 71-3 and CONEG approved. EINECS, CEPE and TSCA provide lists of approved ingredients.
-
What label size?
Round, rectangular, according to own drawings or adapted to a specific container. Tolerance?
-
Delivery specifications?
On roll (in- and outside diameter), sheet or zigzag. Label orientation, amount of labels on each roll, packaging size, type of packaging depending on transportation.
-
Label design?
How many colours on front and back side, or perhaps with digital print. Gloss or matt finish. Material characteristics. Environment issues - PVC, aluminium? |
