Heavy duty packing tape in 35 micron polypropylene film with an acrylic adhesive that unwinds quietly from the dispenser. The RAJA heavy duty low noise polypropylene packaging tape is rated for cartons over 30kg and is designed for high-throughput industrial packing lines where both load strength and quiet application are required. UV resistant once applied. Available in brown and clear, in 48mm and 75mm widths, 66m and 100m roll lengths on a 76mm core.
Heavy duty packing tape in 35 micron polypropylene with acrylic adhesive for quiet application. 55 microns total thickness, rated for cartons over 30kg, UV resistant once applied. Available in brown and clear, two widths, two roll lengths.
The low noise characteristic comes from the acrylic adhesive. Standard polypropylene hot melt tape stretches and snaps back against the film as it unwinds, producing a loud ripping sound. Acrylic adhesive releases gradually and quietly from the backing film, regardless of roll speed or dispenser type. On heavy industrial packing lines where multiple dispensers run simultaneously, switching to acrylic adhesive tape eliminates the cumulative noise of hot melt application without any change to seal strength or weight rating. Acrylic adhesive also provides UV resistance once applied, maintaining seal integrity in brightly lit and outdoor storage environments.
The 35 micron film is the thickest in the standard polypropylene tape range, providing the tensile strength needed to hold heavy carton seams under transit and stacking load. At 55 microns total thickness, the tape resists the splitting, necking and puncturing at carton edges that thinner grades are susceptible to under heavy loads. The additional film gauge also lays flat across the seams of double-wall and heavy corrugated board, which has a more pronounced surface profile than standard single-wall board.
The acrylic adhesive provides UV resistance once the tape is applied and bonded to the board surface. Seals remain intact in brightly lit industrial warehouses, outdoor holding areas and UV-exposed transit environments. Store rolls in sealed original packaging away from direct sunlight before use; UV resistance applies after application, not before.
The 48mm width suits standard carton seams on industrial lines. The 75mm width suits larger double-wall carton formats and wide base seams where greater coverage reduces the risk of bridging. The 100m roll length reduces roll change frequency on high-volume lines; the 66m roll suits lower-volume industrial operations. All rolls use a 76mm core compatible with all standard and low noise dispensers.
Acrylic adhesive on heavy carton seams requires firm pressure and adequate dwell time; the weight of the carton does not substitute for correct application technique.
Inspect the seam area for dust, moisture and contamination before taping. On heavy cartons, a contaminated surface is a greater risk than on lighter cartons because the adhesive contact area relative to the load is lower. Wipe dusty or damp seams with a dry cloth before applying. Allow cartons that have been stored in cold areas to reach ambient temperature before sealing; acrylic adhesive loses initial tack below 0°C.
Seat the roll on the dispenser spindle with the adhesive side facing the blade. Pull approximately 10cm of tape over the blade and confirm it seats flat without bunching. Use the RAJA low noise tape dispenser (PDT02202) for the quietest possible application at both the unwinding and cutting stages. On heavy carton lines, confirm the dispenser blade is sharp at the start of each shift; a blunt blade leaves frayed tape edges that reduce the bonded area at the seam ends.
Start at the centre of the top or bottom seam and draw the dispenser in one continuous pass toward the carton edge, then back to centre and out toward the opposite edge. For cartons over 30kg, run an additional strip of tape across each end panel to close the H-seal fully. The end-panel strips are particularly important on heavy cartons, where the unsupported seam area at the carton corners is under greater load stress during handling and stacking.
Run the heel of your hand or the back of the dispenser blade along the full length of the tape immediately after laying. Acrylic adhesive develops peel strength through sustained contact pressure and takes 15 to 30 seconds to reach full bond strength. On heavy cartons this dwell time is critical; a seal that has not been pressed fully and allowed to set will hold during bench handling but can fail under the impact load of stacking or conveyor movement. Do not place heavy cartons on a conveyor or stack them immediately after sealing.
Store rolls horizontally in original sealed packaging at 15°C to 25°C with humidity below 65%. Do not store in unheated areas, near external doors or in warm storage areas near heat sources. Shelf life is 12 months from manufacture. Write the delivery date on each case on arrival and rotate stock using a first-in, first-out system. Beyond 12 months, acrylic adhesive degrades and will not develop full bond strength on heavy cartons even under correct application conditions.
This heavy duty packing tape sits at the top of the low noise range. Step down for lighter loads; step across to the 32 micron grade where noise is not a concern.
Cartons are up to 20kg and quiet application is needed. The same acrylic adhesive chemistry, lower film gauge and lower cost per roll make this the correct choice for lighter loads in noise-sensitive environments.
Cartons are over 30kg and quiet application must be maintained. The 35 micron film provides the load strength for heavy industrial cartons while the acrylic adhesive keeps unwinding noise to a minimum. This is the correct choice for operations that have outgrown the standard low noise grade on weight but cannot accept the noise of hot melt tape.
Cartons are between 20kg and 30kg and noise is not a concern. The natural rubber adhesive on the 32 micron grade provides faster initial grab and bonds more quickly on contact than acrylic, making it the right choice for fast lines where dwell time is limited and noise is acceptable.
The operation requires kerbside recyclable packaging on heavy cartons. Self-adhesive reinforced paper tape is rated for cartons over 30kg and is recyclable with the box without tape removal.
RAJA heavy duty packing tape (PDT01547) is a 35 micron polypropylene film tape with an acrylic adhesive that unwinds quietly from the dispenser. At 55 microns total thickness, it is rated for cartons over 30kg and is designed for high-throughput industrial packing lines where both load strength and quiet application are required. Available in brown and clear, in 48mm and 75mm widths, 66m and 100m roll lengths on a 76mm core.
The heavy duty low noise grade (PDT01547) uses a 35 micron film, has a 55 micron total thickness, and is rated for cartons over 30kg. The standard low noise grade (PDT01868) uses a 28 micron film, has a 46 micron total thickness, and is rated for cartons up to 20kg. Both use an acrylic adhesive for quiet unwinding. The heavy duty grade is the correct choice where load capacity needs to increase but quiet application must be maintained.
The low noise characteristic comes from the acrylic adhesive. Standard polypropylene tape uses a hot melt adhesive that stretches and snaps back against the film as it unwinds, creating a loud ripping sound. Acrylic adhesive releases from the backing film gradually and quietly. This applies whether the tape is used with a standard dispenser or the RAJA low noise tape dispenser (PDT02202).
Polypropylene tape cannot be recycled in paper or cardboard streams. The polypropylene film must be removed from corrugated board before the board is recycled. Polypropylene tape requires specialist plastic film collection; it cannot go in household kerbside recycling. For operations where kerbside recyclability is required, use self-adhesive reinforced paper tape, which is recyclable with the box.
Yes. All rolls are wound on a 76mm core, which fits all standard pistol-grip and bench-mounted tape dispensers. Use the RAJA low noise tape dispenser (PDT02202) for the quietest possible application at both the unwinding and cutting stages.
Heavy duty low noise tape is rated for cartons over 30kg. For cartons up to 20kg where quiet application is needed, use the standard low noise grade (PDT01868). For cartons between 20kg and 30kg where noise is not a concern, the 32 micron heavy duty grade (PDT00449) is an option.
Acrylic adhesive requires a clean, dry surface and firm pressure along the full seal length to develop its bond. It takes 15 to 30 seconds to reach full peel strength after application. Applying to dusty, damp or cold board, or failing to press the tape down after laying, are the most common causes of failure. Do not move or stack sealed cartons immediately; allow the bond to develop first.
Store rolls horizontally in original sealed packaging at 15°C to 25°C with humidity below 65%. Shelf life is 12 months from manufacture. Do not store in unheated areas or near external doors. Rotate stock using a first-in, first-out system and do not use rolls beyond the shelf life date.
