Custom Printed Carton Sealing Tape
OPALUS PACK is a manufacturer of custom printed carton sealing tape for finished corrugated carton sealing, hand packing stations, and automatic carton sealing machines. Made with BOPP or PVC backing and acrylic or hot melt adhesive, the tape carries logos or handling marks while holding box flaps closed. Before production, we check print clarity, unwind stability, slitting edges, recycled board bonding, and edge lifting after 24 hours.
- Backing: BOPP film or PVC film
- Adhesive: acrylic or hot melt pressure sensitive adhesive
- Widths: 48mm, 50mm, and 72mm
- Thickness: 40um-65um typical production range
- Roll format: 50m-150m hand rolls, 500m-1000m machine rolls
- Base colors: clear, brown, white, or custom printed background
Product Overview
Custom printed carton sealing tape is applied across the center seam and side legs of finished corrugated cartons. Its sealing result depends on film strength, adhesive contact, carton surface, print repeat, and roll feeding stability.
BOPP backing is selected for print clarity, tensile strength, and machine use. Typical factory reference is 25-45 N/cm tensile strength and 120%-180% elongation at break. PVC film is used when smoother hand unwind, firmer film feel, or quieter manual application is preferred.
Acrylic adhesive suits clean corrugated board, warehouse storage, and export cartons. Hot melt adhesive gives faster initial grab on rougher or dustier surfaces. On recycled corrugated cartons, shorter fibers, dust, and flap rebound can cause edge lifting. In sample observation, we check seam bonding, side-leg contact, flap reopening after compression, and edge lifting after 24 hours.
Print repeat affects the finished box. If repeat length, logo direction, or distance from the slit edge is not reviewed, the message may be cut, shifted, or hidden under the carton seam.
Benefits
- Seals corrugated cartons while adding printed identification on the same tape surface.
- BOPP and PVC options match print clarity, film feel, tensile strength, and unwind behavior.
- Acrylic and hot melt adhesives support clean board, recycled board, medium-weight cartons, and faster lines.
- Peel adhesion reference of 4.5-7.5 N/25mm gives procurement teams a clearer sample comparison.
- Holding power reference of >=24 h helps evaluate resistance to carton flap rebound.
- Clean slitting edge checks reduce roll-edge tearing, rough unwind, and feeding interruption.
- Machine roll samples can be reviewed for unwind tension, 3 inch core fit, and tape head feeding stability.
How Should the Adhesive Be Matched to Recycled Corrugated Cartons?
Recycled corrugated cartons can be harder to seal than they look. The board may have shorter fibers, more dust, and stronger flap rebound. Acrylic adhesive is practical for cleaner surfaces and longer storage cycles. Hot melt adhesive is often selected when sealing speed is higher or the carton surface needs stronger initial grab. A sample check should include edge lifting after 24 hours and flap reopening after compression.

Applications
- Corrugated carton sealing for warehouse packing and export boxes
- Finished cartons requiring logo, warning text, or carton ID
- Hand roll use where smooth unwind matters
- Machine roll use requiring stable feeding and fewer roll changes
- Sealing recycled corrugated cartons where higher initial tack may be required
- 72mm wider sealing for larger cartons or wider center seams
- White base for stronger logo contrast, clear or brown base for a clean carton appearance
What Print Repeat and Roll Format Details Affect Sealing Line Stability?
Print repeat is not only a design setting. If the logo repeat is too long, too close to the slit edge, or not aligned with the sealing direction, the carton may show broken text. For hand sealing, 48mm or 50mm rolls suit standard boxes. For machine sealing, 500m-1000m rolls reduce changeover frequency, but they need stable unwind tension, smooth roll edges, and a 3 inch core.
FAQ
What is custom printed carton sealing tape used for?
It seals corrugated cartons while displaying a logo, carton message, warning text, or handling instruction.
Should I choose BOPP or PVC backing?
Choose BOPP for print clarity, tensile strength, and machine compatibility. Choose PVC for smoother hand unwind, firmer feel, or quieter application.
Which adhesive is better for recycled corrugated cartons?
Hot melt gives stronger initial tack on rough or dusty recycled board. Acrylic is better for clean cartons, longer storage, and export packing.
How is print repeat confirmed before production?
Print repeat is checked by logo size, tape width, edge distance, roll direction, and carton sealing layout. Sample rolls are reviewed for logo position, color matching, unwind stability, slitting quality, and sealing performance.
