Woven / Non-woven
The term "non-wovens" refers to products made from textile fibers manufactured without traditional filaments or single-threaded processes.
The fundamental difference between "non-woven" and "woven" yarns is that the former are formed by the union of two distinct components adhering to each other, the latter having toughness to the cohesive forces between the fibers and also to mutual friction.
Duplicate adhesive tapes for paper, film and printing adhesives are used in Vibac tapes.
Acrylic foam support is mainly used by Vibac for the production of high performance Fixing Vertical Mounting Adhesive Tapes. Most commonly used for high temperature resistant permanent assemblies, on superficial surfaces. It is ideal for use before painting processes in dusty environment. Suitable for various surfaces such as glass, metals etc.
Vibac V-HP tapes with acrylic foam support are the best alternative to the classic mechanical assembly systems for rolling, such as screws and welds.
Satured semi-crepe paper
The semi-crepe paper is of varying weight (especially in the range of 40-70 g / m2) and is produced from 100% virgin fibers of excellent quality and posesses the technical characteristic of mechanical resistance to breakage. It offers a great deal of use especially for the production of masking ribbons and the crepe ensures its conformability.
Prior to being coated with different technology adhesives, the paper undergoes impregnation with lactic matter of different chemical nature to improve its mechanical properties.
WASHI cards (or Japanese paper), although having a lower weight and thickness than semi-crepe paper (about 40% less), have comparable mechanical resistance and breakage features.
The washi paper is used by Vibac in adhesive tape manufacturing for precision masking and applications on delicate surfaces, especially in the construction industry.
The low thickness of the washi paper, in fact, allows a precise cut of the ribbon and therefore an exact paint finish.
A primer is an additional layer between the support and the adhesive that serve the function of binding them. It is used to increase the holding power of the adhesive to the backing. The primer can be a liquid substance coated onto the backing material, or a physical treatment, such as corona or a flame treatment. This is especially important if the tape needs to remove cleanly, or if the tape is stressed permanently with a load.
Removable material that protects the adhesive support and is removed before application. A release liner is mainly used with double-sided tapes. It is usually made up of paper or plastic film treated with detachable agents. The optimal liner choice depends on the application. If a die-cut ability is required, polyester liners are preferable. If the tape is exposed to humidity, poly-coated papers are mainly used due to their dimensional stability. For most applications, paper liners are the liners of choice.
A layer of anti-adhesive material applied on the back of the support to allow / facilitate the roll out of the ribbon. The release coating ensures stable unwinding of the tape during the application. This is very important for automatic applications in which the tape can be unwound at high speeds. A release coating can have different release forces for either easy unwinding or harder unwinding, depending on the customer’s needs.
The inner cardboard or plastic cylinder on which the tape is wrapped. Measurements are usually expressed in inches.
A tape's ability to accept and hold a printed legend, as well as its ability to resist offset of the printing when rewound into a roll after printing.
A large roll of tape or backing which is wound up as the material emerges from the coater or treatment. It is later converted.
