This is a single-sided splice. The paper is not overlapped; rather it butts up against each other and you use a single-sided tape to connect the two pieces over the seam. Overlap splice. This is a double-sided splice, where the ends are overlapped.
W or V splice. Although W and V splices are being phased out, the process was most often used in newsprint and paper mills. The W or V pattern of the tape application creates more surface area, making the seam less likely to tear. Is this a Single or Double Coated application? Single-coated splicing tape is suitable for butt splicing. Double-coated splicing tapes are suitable for use with laminators, coaters, and other converting operations.
Double-sided tapes are commonly used in flying splices, manual splices, core starting, and roll finishing applications. What field conditions are you dealing with? Will the splice be subjected to heat? For example, in certain manufacturing processes, flying splices may often need to go through a heat chamber and so high-temperature resistance is critical so the tape does not fail.
How fast or how slow? Manual or zero speed splices happen by hand, so the roll or machine is either not moving or is moving so slowly zero speed that getting a good stick is easier. Flying splices, on the other hand, happen quickly. Both rolls are moving very quickly, yet the splice still needs to get made. Moisture or Humidity. Repulpable splicing tapes dissolve in water.
These splicing tapes ensure that the substrate and adhesive do not gum up the machinery and stop the production process in the production of paper, where water is used. Need something else? See all products. In our experience, splicing tape failures typically occur for one of five reasons: Temperature.
Once a splice is made, many times they will get subjected to high heat down the manufacturing line. And as we already know, the tackiness of the adhesive tape is very temperature-dependent.
Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick.
It typically has higher tack will feel stickier to the touch , but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE : it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools you do not need to apply heat to the tape yourself.
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't recycled fibers, dust, cold, heat and heavy loads. It provides good overall adhesion and moisture resistance. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons.
While it has good initial adhesion it does take hours to cure and to achieve its maximum bond strength has gradual adhesion buildup. Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier e.
It is the best choice for clarity, UV resistance and aging characteristics. Splicing tapes are commonly used in the manufacturing industry such as joining two PVC pipes , film joining film stock , electrical joining two wires and the printing industry joining two paper rolls for continuous web printing.
Channeled Resources offers a variety of splicing tapes to fit your needs. Our silicone splicing tapes, ST-1 and ST-2, provide high-performance splicing of silicone coated films, papers, and release coated surfaces. ST-1 silicone splicing tapes are self-wound and are a perfect choice for use in most processing equipment due to its high bonding strength high-temperature integrity. ST-2 silicone splicing tapes are also self-wound, maintain their integrity in higher heat environments, and have a high-tack silicone adhesive which allows it to create a superior bond.
Elite Tape offers an extensive line of single-coated and double-coated splicing tape formulations that will function in the most complex applications. The most important things to remember in identifying the right splicing tape is finding the balance of initial adhesive bond, shear holding power, and temperature resistance required for your application. Non-Repulpable Splicing tapes are most commonly used for core startup, splicing and roll end tabbing in the coating, laminating, printing, converting and die cut processes.
Our single-coated and double-coated splicing tapes are specifically designed to provide superior adhesion to the most challenging LSE surfaces such as coated films and papers, as well as provide high heat and shear resistance for all of your application conditions. Attaching two substrates by overlapping the roll ends and applying a double coated splicing tape to bond the overlapped section.
Butt Splice: Attaching two substrates by butting the roll ends together and applying a single-coated splicing tape over the top and bottom of the seam.
