Method for processing coiled BOPP film adhesive tape

Abstract

The invention discloses a method for processing a coiled BOPP film adhesive tape, which comprises a coiled tape adhering step. The coiled tape adhering step comprises the following operations: firstly, performing surface structure homogenized treatment on an adhered surface of the adhesive tape to ensure that the surface tension of the adhered surface is 35 to 45 dynes; and while adhering a loweradhesive tape to an upper adhesive tape, uniformly extruding the surface of the upper adhesive tape along the rotary coiling opposite direction of the tape. Through the surface structure homogenized treatment, the adhered surface of the tape has uniform structural distribution, and the surface of the upper adhesive tape is extruded during coiling the tape to discharge the air between the adheringsurface and the adhered surface, so adhesion between the upper and lower tapes of the coiled BOPP film adhesive tape is quite uniform, the noise produced by the tapes is greatly reduced during drawing and breaking the tape in use, and the noise of the tape can be reduced to below 30 decibels through detection.

Description

technical field [0001] The invention relates to a processing method of roll-type BOPP film adhesive tape, in particular to a processing method of low-noise roll-type BOPP film adhesive tape. Background technique [0002] BOPP is the abbreviation of "Biaxially Oriented Polypropylene", that is, biaxially oriented polypropylene film, which is a common material for the production of adhesive tapes. The roll-type BOPP film adhesive tape of the prior art is a commonly used auxiliary material for packaging and sealing. This roll-type BOPP film adhesive tape will produce very large noise during use. According to experimental measurements, sometimes the produced The noise can reach more than 70 decibels, especially in public places, it will become an intolerable noise source for people. [0003] Because in the prior art, the processing process of the roll-type BOPP film adhesive tape, the bonded surface of the roll-type tape film is not pretreated, so that the outer surface of the r...

The roll-type BOPP film adhesive tape of the prior art is a commonly used auxiliary material for packaging and sealing. This roll-type BOPP film adhesive tape will produce very large noise during use. According to experimental measurements, sometimes the produced The noise can reach more than 70 decibels, especially in public places, it will become an intolerable noise source for people

[0003] Because in the prior art, the processing process of the roll-type BOPP film adhesive tape, the bonded surface of the roll-type tape film is not pretreated, so that the outer surface of the roll-type tape film is the side microstructure of the bonded surface 120 Shown as extremely uneven unevenness (such as image 3 As shown), in the process of bonding and reeling the adhesive tape, the bonding of the tape surface between the upper and lower layers of the roll-type tape will appear uneven. When the user pulls the upper layer of the roll-type tape forcefully When opening, due to the uneven bonding between the upper and lower tapes, the separation between the surface of the lower tape and the rubber surface 110 of the upper tape, each point of the tape in the vertical direction of tension will be pulled up and torn unevenly. open, causing the tape to vibrate intermittently and cause noise

At the same time, in the process of bonding the tape, the air between the upper and lower layers of tapes was not completely removed, so that part of the air was bonded between the upper and lower layers of tapes, which further caused the surface of the tape film between the upper and lower layers to be different. Inhomogeneous bonding occurs, which in turn will cause the tape to vibrate when the upper and lower tapes are separated, resulting in noise
