Adhesive Pack Tape Company is a Bopp Hot Melt Tape manufacturer producing BOPP hot melt carton sealing tape for hand dispensers and automatic case sealers. The tape uses biaxially oriented polypropylene film, a controlled release coating, and pressure sensitive hot melt adhesive to support quick carton grab, smooth unwind, and stable closure on corrugated boxes. Clear, transparent, brown, and buff rolls are available for warehouse packing, export cartons, and production sealing.
Product Overview
Bopp Hot Melt Tape is made for carton sealing where fast adhesion, clean unwind, and film strength all matter. The BOPP film backing is commonly controlled within 23-32 um, giving the tape tensile strength, clarity, and controlled elongation. Factory reference tests usually check tensile strength around 35-45 N/cm and elongation at break around 100-130%, which helps the tape run through a hand dispenser or case sealer without easy snapping.
The adhesive layer uses synthetic rubber hot melt technology. With adhesive coating weight commonly controlled around 16-23 g/m2, it makes fast contact with carton fibers on corrugated boxes, linerboard boxes, recycled cartons, and testliner surfaces. For rough board, fiber dust, coated cartons, or high recycled content, sample sealing should be checked before bulk use because surface condition can affect peel adhesion, holding power, and flap closure after 24-72 hours.
This tape should not be selected by total thickness alone. Total thickness, BOPP film thickness, adhesive coating weight, and release behavior work together. Clear rolls keep labels, barcodes, and printed graphics visible. Brown or buff rolls match kraft cartons better. For machine rolls, edge alignment, core fit, unwind force, and tape tracking should be confirmed before production.
Benefits
- Quick tack helps carton flaps stay closed soon after sealing.
- BOPP film backing supports tensile strength and controlled stretch.
- Release coating supports smoother unwind and steadier roll tension.
- Synthetic rubber hot melt adhesive works well on many recycled carton surfaces after sample testing.
- Machine-roll options help reduce stoppages when core fit, edge alignment, and unwind force are stable.
- Sample sealing checks can observe flap lift, edge lifting, or seam opening after 24-72 hours.
- Consistent adhesive coating helps reduce dry edge, heavy spot, weak tack, and uneven sealing problems.
How does the release coating affect carton sealing performance?
In BOPP hot melt tape, the release coating controls how the tape comes off the roll. For manual sealing, it gives a steadier pull and reduces sudden stretching. On automatic case sealers, stable release helps lower drag, uneven tension, and roll hesitation during continuous packing. This matters for longer machine rolls because poor unwind can lead to tape breakage, weak carton contact, or repeated line stops.

Applications
- Hand dispenser sealing in warehouse packing areas.
- Automatic case sealer use on continuous packing lines.
- Medium-weight corrugated carton closure for daily shipments.
- Recycled carton and testliner box sealing after sample confirmation.
- Clear sealing where labels, barcodes, or printed graphics must remain visible.
- Brown or buff sealing for kraft box packaging.
- Export carton sealing where flap rebound should be checked before bulk packing.
What makes BOPP hot melt tape different from acrylic BOPP tape?
BOPP hot melt tape is usually chosen when fast carton grab and reliable sealing on corrugated board are more important than long outdoor exposure. Its synthetic rubber hot melt adhesive bonds quickly to carton fibers, while the BOPP film backing gives strength and controlled elongation. In an acrylic BOPP tape comparison, acrylic tape is often more suitable for long storage, UV exposure, or long-term clarity. For daily warehouse packing and machine-applied sealing, hot melt construction gives a faster, more practical carton seal.

FAQ
1. Is Bopp Hot Melt Tape suitable for machine carton sealing?
Yes. Check roll edge alignment, core fit, unwind force, and tape tracking before production use.
2. Should I choose clear or brown rolls?
Choose clear rolls for visible labels or graphics. Choose brown or buff rolls for kraft cartons.
3. Can this tape seal recycled cartons?
Yes, but surface dust, fiber quality, coating condition, and flap rebound should be tested first.
4. What thickness grade should be selected?
Regular cartons can use standard grades. Machine sealing, recycled board, or heavier cartons may need higher thickness and stronger adhesive coating.
