Packaging Tape
Packaging tapes and films are used to seal or
wrap boxes, bottles or other packages. Packaging tape and films
include adhesive packaging tapes, shrink wraps, stretch films and
other specialty papers and roll good products such as rust preventive oil papers, volatile corrosion inhibitor (VCI) wraps or moisture barrier films.
Packaging tapes and films temporarily or permanently join materials together. Tapes consist of an adhesive-coated backing called a carrier. Single-sided tape is used to attach overlapping or adjoining materials.
Double-sided tape is coated with adhesive on both sides and allows the joining of items back-to-back. Films are synthetic resin adhesives that sometimes include a carrier fabric.
Typically, films are made of thermosetting resins and are used under heat and pressure as an interleaf in the production of bonded structures. Transfer tape, a highly versatile product that consists of a thin adhesive film without a carrier, can be transferred to most dry surfaces from a peel-away release liner.
Packaging tapes and films vary in terms of carrier material. Aluminum foil is laminated to paper or plastic films for improved strength. Electrodeposited copper foil is used in the manufacture of multilayer printed circuit boards (PCB).
Fluoropolymer films consist of plastics such as polytetrafluorethylene (PTFE) or polyvinylidene fluoride (PVDF) and are used in applications that require superior chemical resistance. Polyimide film maintains its excellent physical, mechanical, chemical and electrical properties over a wide range of physical environments.
Products that use polyester, polyethylene terephthalate (PET) and polycarbonate carriers are often available. Other backing materials include cloth, foam, paper, plastic, rubber, silicone, and urethane. |
