Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a plate mounting tape for preventing edge warping. Background Art

[0002] Plate mounting tape is a double-sided tape specially designed for fixing photosensitive resin plates on flexible printing rollers or sleeves. At present, the tape used for printing plate mounting mainly adopts imported materials, which is expensive, and gas is easy to exist in the adhesive layer laminating space during the use of the tape, which affects the flatness of the adhesive layer. Among them, a flexographic printing plate mounting tape with application number "CN201320593315.2" includes a PE foam base layer, a pressure-sensitive adhesive and a PET exhaust release film; wherein, the pressure-sensitive adhesive is pasted on one side of the PE foam base layer, and the other side of the PE foam base layer is pasted with the PET exhaust release film through acrylic adhesive; in addition, the PE foam base layer is provided with uniform round bubbles. The utility model has good creep resistance and shear resistance, and will not leave residue when peeled off, which is convenient for replacing plates; the low initial viscosity facilitates accurate positioning of plates, and adopts removable pressure-sensitive adhesive, whose sustained viscosity can prevent the displacement of plates during machine operation, improve printing quality, and reduce printing times. However, the plate mounting tape still has the following defects when used: the connection between the PE foam base layer and the side of the pressure-sensitive adhesive is relatively weak, which is prone to debonding and warping during printing.
