Hot Melt Carton Sealing Tape
OPALUS PACK is a hot melt carton sealing tape manufacturer producing BOPP sealing tape with synthetic rubber hot melt adhesive for fast carton closure. It is made for recycled corrugated cartons, manual tape guns, semi-automatic sealers, and high-throughput sealing lines where the tape must grab quickly and keep flaps closed. The focus is fast initial tack, quick stick, controlled unwind, and reliable holding force during packing, storage, and export shipment.

Product Features and Benefits
Product Overview
Hot melt carton sealing tape from OPALUS PACK is built for carton sealing work that needs immediate bonding. The tape uses BOPP film coated with synthetic rubber hot melt pressure-sensitive adhesive, giving it a fast grab under hand pressure, tape gun pressure, or the compression wheels of an automatic case sealer.
This is not an acrylic-based sealing tape. Acrylic grades are often selected for clarity or aging resistance; this product is selected when sealing speed, flap holding, and quick contact with paper fibers are more important. On busy packing tables or conveyor lines, the tape must bond within seconds before the carton moves to palletizing or transfer.
The difference is clear on recycled corrugated cartons. Recycled linerboard can be rougher and more porous than virgin board. In factory sealing checks, our hot melt grade is pressed onto single-wall and double-wall cartons to observe initial grab, flap rebound, edge lifting, and center seam contact. For hand and machine rolls, unwind force is adjusted to reduce stretching, snapping, cutter drag, and roll changes during continuous shifts.
Benefits
- Fast initial tack helps carton flaps stay closed soon after sealing.
- Quick stick supports rough or porous recycled corrugated surfaces.
- Peel adhesion of 5.5-8.5 N/25 mm supports sealing checks.
- Tensile strength of 80-140 N/25 mm helps during transport.
- Holding power of >=24 h helps maintain closure after compression.
- Smooth unwind supports manual tape guns and automatic sealing machines.
- Width tolerance of +/-1 mm helps keep tape centered on seams.
How Does Synthetic Rubber Hot Melt Adhesive Improve Carton Sealing Speed?
Synthetic rubber hot melt adhesive is chosen for fast initial tack. After light pressure, it quickly contacts carton fibers and helps hold flaps before rebound occurs. This matters on a high-throughput carton sealing line where each carton stays in the sealing area briefly. Short compression tests help check stable contact before the carton leaves the packing station.

Applications
- Recycled corrugated carton sealing in warehouses and distribution centers
- Medium-weight carton closure for fulfillment and export packing
- Automatic carton sealing on high-volume packaging lines

- Outer carton sealing for dry food packing rooms after sample testing
- Printed carton sealing tape for handling marks or identification
What Should Be Checked Before Using It on Recycled Cartons or Cold Packing Areas?
Recycled corrugated cartons may have dusty fibers, uneven linerboard, or stronger flap rebound, so testing should use the actual carton material. For cold packing areas, selected hot melt grades can be checked at the real storage and sealing temperature. Key checks include bonding speed, flap holding, edge lifting, unwind stability, sealing pressure, and machine speed.
FAQ
Is this hot melt carton sealing tape an acrylic tape?
No. It uses synthetic rubber hot melt adhesive. Its focus is fast initial tack, quick stick, and carton flap holding.
Can it be used on recycled corrugated cartons?
Yes. It is suitable for rough or porous recycled linerboard. Sample testing is recommended for dusty fibers or strong flap rebound.
Is it suitable for automatic carton sealing machines?
Yes. OPALUS PACK supplies hand rolls and machine length rolls with stable unwind, controlled width tolerance, and consistent winding.
Can the tape be used in cold packing areas?
Selected hot melt grades can be tested for cold rooms, winter warehouses, or damp carton handling before bulk use.
