Common Tape BackingsTypes of backings:
There are several different types of backings: Acetate, Cotton Cloth, Filament Reinforced,
Metallic, Polyolefin, Polyester, Polyethylene, Polypropylene, PVC, Rayon & UPVC.
Acetate Film:
Transparent film that is moisture resistant.
Cotton Cloth Film:
Offers very good flexibility & conformability whilst retaining its tensile strength. Can be coated with
various adhesives & torn by hand.
Filament Reinforced Film:
Commonly associated as a filament tape it offers excellent tensile strength. Glass fibers give tape strength & can not be torn by hand. Can be coated with various adhesives on an OPP or Polyester film.
Metallic Film:
Usually made from aluminum the film has excellent insulation & flame retardant prosperities & resistance to solvents. Can be reinforced with woven material to provide extra tensile strength.
Polyester Film:
Synthetic film with high tensile strength to which different adhesives can be coated. Versatile film that can be used inside or outside with excellent resistance to moisture, abrasions, chemicals & solvents depending on type of adhesive coating. Film has low stretch characteristics.
Polyethylene Film:
Tough film that works well at low temperatures with good tensile strength to which different adhesives can be coated. Film that can be used inside or outside with excellent resistance to moisture, abrasions, chemicals & solvents depending on type of adhesive coating. Exhibits good isolation properties.
Polyolefin Film:
Economical film with a matt finish to which different adhesives can be coated. It can be applied easily by hand. Softer & more flexible than OPP, this film offers silent unwind with higher abrasion resistant than OPP films & is generally biodegradable. Film can be printed on.
Polypropylene Film (BOPP):
BOPP = Bi axially oriented polypropylene (same stretch along and across the film). Economical film to which different adhesives can be coated. It can be applied easily by hand or machine roll form. This is the most commonly used backing material for packaging tape & is generally biodegradable. Can be metallised for decorative & other specialist applications. Film can be printed on.
Polypropylene Film (MOPP):
MOPP = mono axially oriented polypropylene (tensalised along the length of the film ensuring no stretch). Economical film to which different adhesives can be coated. It can be applied easily by hand or machine roll form. This is mainly used for strapping / palletising tapes as the film has no stretch.
PVC Film:
Plasticised Poly-Vinyl Chloride. Softer & more flexible than UPVC, this film is highly conformable & also exhibits excellent resistance to abrasions, oils, chemicals & solvents. Film offers silent unwind with higher abrasion resistant than OPP films & offers reduced stretch. Film can be release coated for
easy unwind & is not biodegradable, therefore not considered to be environmentally friendly. Generally suitable for hand applications only.
Rayon Cloth Film:
Offers very good flexibility & high tensile strength. Usually coated with polyethylene the cloth is resistant to chemicals, solvents & weathering. Can be coated with various adhesives & torn by hand.
UPVC Film:
Unplasticised Poly-Vinyl Chloride. A tough durable film having excellent resistance to abrasions, oils, chemicals & solvents. Film offers silent unwind with higher abrasion resistant than OPP films & has low stretch. Film is hard to unwind & is not biodegradable, therefore not considered to be environmentally friendly. Can become brittle in cold conditions. Generally suitable for hand
applications only. Film can be printed on.
