BOPP Tape For Carton Sealing
- Backing: Transparent BOPP film
- Adhesive: Water-based acrylic PSA
- Core: 3 inch paper core option
- Widths: 36-72 mm common range
- Lengths: Finished rolls and machine rolls
- Use: Corrugated carton sealing
Pro Pack Tape Company is a manufacturer of BOPP Tape For Carton Sealing for warehouse packing, export cartons, and continuous sealing lines. This transparent BOPP packing tape has the familiar clear cello-style appearance used for carton closure, but the backing is tear-resistant biaxially oriented polypropylene film rather than cellophane. It is intended for corrugated cartons where readable labels, quick initial tack, dependable holding power, and smooth unwind matter during manual, semi-automatic, or automatic sealing.

Product Overview
This clear carton sealing tape keeps carton marks, shipping labels, and barcodes visible after application. Its BOPP backing adds tensile strength and tear resistance during handling, stacking, and transport. Typical grades use a total thickness of 40-65 um with a 23-40 um BOPP film backing, subject to the adhesive coat and sealing requirement.
Choosing a suitable grade involves more than carton weight. Board quality, recycled-fiber content, surface dust, flap tension, storage conditions, and the sealing method can all affect the result. Smooth cartons made from consistent board often perform well with a standard acrylic grade. Rough recycled corrugate may need a higher tack level and a more careful trial.
For repeat production, thickness, slit-width consistency, winding quality, and unwind behavior should be reviewed together. Trial cartons should be inspected immediately after sealing and again after an agreed storage period. This helps identify delayed edge lifting or flap reopening before bulk use.
Benefits
- Transparent appearance helps keep labels, barcodes, and carton marks visible.
- Tear-resistant BOPP backing supports reliable closure during shipment.
- Initial tack helps the adhesive contact the carton surface quickly.
- Holding power helps reduce edge lifting after stacking and storage.
- 3 inch core packing tape formats suit longer industrial runs.
- Acrylic adhesive packing tape options can be matched to manual or machine use.
- Consistent slitting and winding help reduce avoidable line interruptions.
How Should a 3 Inch Core BOPP Tape Be Matched to a Carton Packing Line?
A 3 inch paper core is approximately 76.2 mm and is commonly used for longer industrial rolls. The core should be considered as part of the complete roll format rather than as a stand-alone specification.
Before a line trial, review tape width, roll length, outside roll diameter, winding direction, unwind consistency, and tape-head compatibility. The automatic carton sealing tape should feed smoothly, press evenly across the center seam, and run without frequent adjustment. Wipe-down pressure also deserves attention because the adhesive needs even contact with the corrugated surface.
A 50-75 mm side tab can be used as an initial setup reference and then adjusted to the carton size and equipment settings.

What Should Be Checked If Clear BOPP Tape Starts Lifting After Carton Sealing?
Fast initial tack does not always mean the carton will remain closed after stacking or storage. If tape edges lift or carton flaps reopen, review holding power, peel adhesion, carton dust, recycled-fiber content, surface roughness, flap tension, and wipe-down pressure.
Acrylic adhesive can continue building contact after application, so the check should not stop at the end of the packing line. Compare the immediate result with a later storage inspection. Before repeat production, use retained samples to review thickness, slit-width tolerance, adhesive grade, roll format, winding quality, and unwind behavior.

FAQ
Is this product made from cellophane film?
No. It has a clear cello-style appearance, but the backing material is transparent BOPP film.
Can the tape be used on automatic carton sealing machines?
Yes. The roll format, tape-head compatibility, and unwind behavior should be checked during a line trial.
Why should recycled corrugated cartons be tested before bulk production?
Recycled cartons can have dustier, rougher, or less uniform surfaces. Testing helps verify tack, holding power, and edge-lifting performance.
Which parameters should be checked for repeat production?
Review thickness, adhesive grade, slit width, roll format, winding quality, retained samples, and agreed performance tests.
