BOPP Jumbo Roll Adhesive Tape

BOPP Jumbo Roll Adhesive Tape is supplied before final slitting and rewinding. It is not a small finished roll for direct carton sealing. It is a coated web used by tape converting plants to make finished packing tape in different widths. A reliable Jumbo roll should unwind smoothly, keep balanced web tension, and hold consistent adhesion from the outer layer to the core.

Procurement teams should compare more than nominal width and total thickness. Film thickness, adhesive coating layer, peel adhesion, and holding force affect carton sealing performance. Tensile strength, elongation, bopp jumbo roll weight, end-face flatness, roll hardness, and usable coating width affect slitting yield. A 1280mm or 1620mm roll may look correct on paper, but uneven edge coating or unstable unwind force can reduce output.

Product Range / Covered Products

This category covers clear BOPP jumbo roll adhesive tape, super clear OPP adhesive jumbo rolls, yellowish and tan jumbo rolls, standard acrylic adhesive jumbo rolls, stronger holding grades, and long-run rolls for fewer machine changeovers.

Selection Guide

Select the bopp jumbo roll size by machine width, finished tape width, knife layout, usable coating width, and trimming loss. A 1280mm roll is common for 1300mm-class slitting lines, while 1620mm suits wider machines and higher output. Before edge trimming, 1280mm can be planned for about 26 lanes of 48mm tape, 25 lanes of 50mm tape, or 17 lanes of 72mm tape. A 1620mm roll can be planned for about 33 lanes of 48mm tape, 32 lanes of 50mm tape, or 22 lanes of 72mm tape.

Thickness should match the finished carton sealing requirement. About 33um-45um supports lighter output. About 45um-52um is common for standard carton sealing tape. About 55um-70um is better for stronger film, higher holding force, or heavier cartons. Film thickness and adhesive layer should be confirmed separately because the same total thickness can behave differently in tack, elongation, and rewound roll density.

Benefits

• Converts efficiently into 48mm, 50mm, 60mm, 72mm, and custom widths.
• Reduces trimming loss when usable coating width is confirmed early.
• Keeps adhesive performance consistent across different slitting lanes.
• Supports cleaner cutting with stable BOPP film strength.
• Allows tack, peel adhesion, holding force, and unwind force adjustment.
• Helps reduce telescoping, loose finished rolls, and uneven side faces.
• Supports checks such as bubble, fish-eye, blade-edge cleanliness, unwind tracking, and rewound roll density.

How Should Converters Select BOPP Jumbo Roll Adhesive Tape for Finished Tape Output?

The right selection starts with jumbo width, usable coating width, trimming allowance, and target finished tape size. For a 1280mm or 1620mm jumbo roll, the useful value is not only the printed width, but the coated area that can be slit cleanly. Converters should test the roll under real machine tension and check whether 48mm, 50mm, or 72mm finished rolls keep a clean side face after rewinding.

TDS / Technical Range

Applications

• Tape converting plants producing finished carton sealing tape.
• Slitting and rewinding workshops using 1300mm-class or 1600mm-class equipment.
• Packaging material suppliers converting jumbo rolls into different finished widths.
• Regional distributors needing stable jumbo roll supply for repeated output.
• Bulk conversion batches where roll weight, coating width, rewind stability, and slitting yield affect production.

Customization Options

China Pack Suppliers Company can adjust width, roll length, total thickness, film thickness, adhesive coating layer, color tone, tack level, peel adhesion, holding force, unwind force, roll hardness, core size, and usable coating width. For accurate matching, procurement teams should share target finished tape width, machine width, roll length, thickness, storage conditions, and final carton sealing application.

Before bulk production, useful checks include 24-hour adhesion observation on corrugated carton, unwind tension tracking at machine speed, edge lifting check after slitting, side-face flatness after rewinding, and finished roll tightness from outer layer to core.

What Affects Rewinding Stability During BOPP Tape Jumbo Roll Conversion?

Rewinding stability depends on coating uniformity, web tension, roll hardness, end-face condition, and adhesive behavior during cutting. If the adhesive layer is uneven or the roll releases with unstable tension, the line may face wrinkles, telescoping, glue transfer, loose rolls, or uneven finished roll density. A stable roll should unwind smoothly and keep the rewound tape side face flat after machine conversion.

FAQ

What bopp jumbo roll size is suitable for 48mm, 50mm, and 72mm finished tape?

1280mm and 1620mm are common choices. The suitable bopp jumbo roll size depends on machine width, knife layout, usable coating width, edge trimming allowance, and planned finished tape width.

How is bopp jumbo roll weight estimated?

Bopp jumbo roll weight is affected by width, roll length, total thickness, film thickness, adhesive layer, paper core, and wrapping method. For example, 1280mm x 4000m x about 45um may be around 200kg-230kg net weight.

Which thickness should be selected for carton sealing tape production?

About 33um-45um suits lighter output, 45um-52um is common for standard tape, and 55um-70um is more suitable for stronger holding or heavier cartons.

What should be checked before bulk conversion?

Check coating uniformity, unwind tension, usable coating width, blade-edge cleanliness, trimming loss, glue transfer, and finished roll density after trial slitting.
