Tape dispensers are used to hold and cut tape depending upon the type of dispenser. The most portable are called "Tape guns" that are handheld and useful for small quantity box sealing or home/office environments.
Tabletop dispensers allow an operator to grab the tape and take it to the point of application.
Manual tabletop dispensers allow an operator to pull and tear any amount of tape, or to dispense a fixed amount of tape by use of a hand lever.
Electric dispensers can be set to dispense a fixed amount of tape automatically either by a push of a button or foot switch or a sensor that detects when the previously cut length of tape has been removed.
It is recommended to test all tapes prior to purchase to make sure you are getting the best dispenser for your application.
