Backing of Vibac Tape


web-based material.

A backing (or carrier) is a relatively thin, flexible, web-based material. It can be made from various kinds of materials, such as paper, film, foil, foam, fabrics, non-wovens, and laminates. Backings are often chosen due to the function they fulfill, such as cushioning, dampening, maintaining a barrier, etc.

Main types of backing:
Backing is a relatively thin flexible material to which the adhesive is applied. Theoretically any material, which is reasonably flat, relatively thin and flexible, can be used as a tape backing. Sometimes it is referred to as carrier.

Vibac backing film used:

  • Biaxially oriented polypropylene (BOPP)

Vibac backing tapes used:

  • Biaxially oriented polypropylene (BOPP)
  • Polyvinyl chloride (PVC)
  • Polyester (PET)
  • Mono-oriented polypropylene (MOPP)
  • Polyethylene (low density: LDPE, high density: HDPE)
  • Woven / Nonwoven
  • Acrylic foam


Biaxially oriented polypropylene film (BOPP)
Bi-oriented polypropylene films coated in different thicknesses and in the various adhesive technologies are available.
The bi-oriented polypropylene film has high surface gloss and good mechanical strength.
It also has excellent resistance to chemical agents such as inorganic salts, inorganic weak acids, alkaline solutions, alcohol and strong oxidizing agents.
The BOPP film is odorless and is widely used in the food industry.
It is used to a large extent for the adhesive tape manufacturing and self-adhesive packaging tapes. Vibac carton sealing tapes are also available in printed and personalized versions.

Monoaxially-oriented polypropylene film (MOPP)
Single-Oriented Polypropylene Vibac Film (MOPP) is obtained during extrusion by operating only one longitudinal orientation. MOPP is coated in various adhesive technologies in order to obtain self-adhesive tapes with very high mechanical strength.
MOPP Film is designed for adhesive tape manufacturing, self-adhesive tapes for heavy packing (ie for all manual packing operations of heavy packs, palletized loads, pipe fittings, blade handles, etc.). The MOPP Vibac film has good resistance to aging even outdoors.

PVC - Polyvinyl chloride
Film made of polyvinylchloride (PVC) polymers. PVC film has good mechanical properties and high resistance to oxidizing agents as well as good lightfastness. Moreover, it has good resistance to chemicals and fire.
PVC film is used for packaging and even for custom and personalized printing.

LD PE - Polietilene
The low density polyethylene film (LDPE) has excellent lightfastness and good resistance to chemical agents. It also has good electrical insulation capacity. It has the mechanical properties of high elasticity and therefore excellent conformability. Thus, the LDPE film is used for producing tapes for particular applications, such as self-adhesive protective tapes.

PET - Polyester
The polyethylene terephthalate (PET) film, produced for extrusion and bi-directional transverse and longitudinal orientation, has high surface gloss and excellent mechanical properties. At the same time it has good hardness, rigidity and mechanical strength as well as good thermal properties.
It is used for adhesive tape manufacturing, self-adhesive tapes specifically formulated to ensure good resistance to temperatures and to fix the components of a product in a stable and long-lasting manner.

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
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 Paper
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.

Release Liner
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.

Release Coating
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.
