Yellow Clear Tape
Foshan Opalus Adhesive Products Co., Ltd. is a manufacturer of yellow carton sealing tape for corrugated carton closure and single-color warehouse identification. This transparent yellow BOPP carton sealing tape is used when cartons need a reliable seal and a clear yellow marking cue at the same time. It helps packing teams separate routes, batches, zones, or shipment priorities while keeping labels readable, rolls flat, slit edges clean, and unwind stable for hand dispensers and carton sealing machines.

Product Details
Product Overview
Yellow carton sealing tape is made for cartons that need sealing performance and quick visual recognition. In a busy warehouse, one yellow tape color can separate export cartons, route groups, inspection batches, or priority shipments without changing carton printing. The transparent yellow version is useful when box marks, shipping labels, or barcode areas must remain visible after sealing.
The tape uses BOPP film backing coated with acrylic, hot melt, or rubber adhesive. A typical structure may use 23-30 um BOPP film with 12-35 um adhesive coating, while total thickness is usually selected within 35-65 um. Acrylic adhesive suits standard cartons where clarity and aging stability matter. Hot melt or rubber grades may be better for recycled cartons, dusty corrugated surfaces, stronger initial tack, or flap rebound control.
Thickness should not be approved by number alone. A thicker tape may still fail if the adhesive does not wet the carton surface, the flap has strong memory, or packing-line pressure is too low. Sample testing should use actual cartons, and a retained approved sample should be kept to compare yellow shade, transparent yellow visibility, adhesive haze, roll surface, and roll-to-roll color consistency.
Benefits
- Yellow single-color sealing separates routes, carton batches, zones, or shipment priorities without extra labels.
- Transparent yellow BOPP tape keeps box codes, labels, and barcode areas more readable than opaque color tape.
- Film thickness, adhesive thickness, and total thickness can be matched to carton weight and sealing pressure.
- Adhesive options can be adjusted for recycled cartons, dusty surfaces, or stronger initial tack.
- Clean slit edge, flat roll surface, and controlled unwind reduce wandering, wrinkling, poor cut-off, and breakage.
- Retained sample comparison supports yellow shade consistency, transparency control, and roll-to-roll color stability.
What Should Be Checked When Yellow Carton Sealing Tape Is Used for Warehouse Identification?
When this tape is used for warehouse identification, the yellow tone should separate one route, batch, storage zone, or shipment priority from ordinary clear tape. For transparent yellow grades, printed marks, labels, and barcode areas should remain readable after sealing. The approved shade should be checked under real warehouse lighting. Useful checks include adhesive haze, old carton printing coverage, label readability, and whether scanning information remains visible after normal sealing pressure.

Applications
- Corrugated carton sealing for warehouse packing and outbound shipping
- Route, batch, zone, or production-lot marking on sealed cartons
- Export carton sealing where printed marks and labels must remain visible
- Recycled carton sealing after dust, flap rebound, and adhesion checks
- Hand dispenser stations requiring smooth unwind, clean tear, and firm center-seam pressure
- Automatic carton sealing machine use requiring flat rolls, stable tension, clean slit edges, and stable cut-off behavior
How Can Yellow Carton Sealing Tape Stay Stable on Hand Dispensers and Carton Sealing Machines?
This tape should be checked as both a sealing material and a running material. For hand dispensers, it should unwind smoothly, tear cleanly, and press firmly over the carton center seam without edge curling. For automatic carton sealing machines, roll flatness, 3 inch core fit, roll diameter, unwind tension, and slit-edge cleanliness matter because unstable rolls may cause wandering, wrinkling, poor cut-off, or breakage. A practical trial should include normal cartons, recycled cartons, printed cartons, and the actual machine speed used in the packing line.
FAQ
1. Is yellow carton sealing tape the same as general colored BOPP packing tape?
No. It refers to yellow or transparent yellow BOPP tape used for carton closure and single-color identification. It supports box sealing, route marking, batch separation, and warehouse zoning, not a general multi-color tape range.
2. Can transparent yellow tape keep carton labels readable?
Yes, when yellow transparency and adhesive haze are controlled. Test it over actual carton printing, labels, and barcode areas before approval.
3. What thickness should be selected for this tape?
Common total thickness is usually 35-65 um. Light cartons may use a thinner grade, while heavier or recycled cartons may need higher adhesive thickness, stronger initial tack, or better holding power.
4. Can this tape run on automatic carton sealing machines?
Yes, if roll length, 3 inch core size, roll flatness, unwind tension, and slit-edge quality match the equipment. Machine trials should check tape tracking, wrinkle control, flap hold-down, cut-off stability, and color consistency.
