Opp Color Tape

Packaging Seal Company is an opp color tape manufacturer for carton sealing, product identification, and production dispatch color control. Made with OPP/BOPP film and acrylic adhesive, this tape helps cartons stay sealed while making product groups easier to recognize in busy packing areas. It is suitable for kraft cartons, recycled corrugated boxes, warehouse sorting, batch packing, and outbound dispatch work. Common 48mm and 50mm widths provide enough sealing contact while keeping the color mark visible.

Product Overview

Opp color tape is made for packing lines where carton sealing and visual control need to happen in the same step. A clear color on the carton helps workers recognize product groups, packing batches, warehouse zones, or dispatch routes without checking every label. Red may mark urgent orders, yellow can show inspection hold, blue can support regional sorting, and green can indicate approved batches.

The tape uses a smooth OPP/BOPP film carrier coated with pressure-sensitive acrylic adhesive. Factory test reference values show a common total thickness of 45um-60um, including 23um-28um BOPP film and 18um-32um adhesive coating. This structure gives the tape a balanced feel: firm enough for daily carton sealing, but still easy to unwind and apply by hand or dispenser. On clean and dry kraft cartons or recycled corrugated boxes, the adhesive can make stable contact with low edge lifting.

For standard carton seams, 48mm and 50mm widths are practical because they cover the center joint and leave a visible color band after stacking or transfer. As a colored OPP carton sealing tape, it also needs clean slit edges, flat roll surface, and controlled unwind, especially on repeated packing work.

Benefits

• Combines carton sealing and visible color identification in one roll.
• OPP/BOPP film provides practical tensile strength of 75-95 N/25mm.
• Acrylic adhesive supports bonding on kraft and recycled corrugated cartons.
• The BOPP color packing tape format helps separate batches, routes, and inspection status.
• Factory reference peel adhesion of 5.0-6.5 N/25mm supports regular sealing performance.
• Controlled unwind force of 2.0-4.5 N/25mm helps repeated sealing feel smoother.

How Can Opp Color Tape Improve Carton Identification During Dispatch?

In a busy dispatch area, a sealed carton still needs to be checked, grouped, moved, and loaded correctly. As OPP tape for warehouse identification, each color can carry a simple handling rule before cartons reach pallets, racks, or outbound lanes. One color may mark checked cartons, another may separate urgent orders, and another may show a product group or route. This makes cartons easier to recognize from a distance and can reduce repeated manual checking when several packing jobs run at the same time.

Applications

• Carton sealing for warehouse packing and e-commerce dispatch
• Product identification by visible carton color code
• Production batch control for different packing lines
• Dispatch route separation in outbound warehouse areas
• Inspection status marking for held, checked, or approved cartons
• High-volume packaging lines that need stable unwind and clean slit edges

What Makes OPP/BOPP Film Suitable for Color Carton Sealing Tape?

OPP/BOPP film is suitable for carton sealing because it gives the tape tensile stability, a smooth surface, and steady roll unwinding. For colored adhesive packaging tape, the film also keeps the color clear across the carton seam. The acrylic adhesive helps the tape bond to kraft cartons and many recycled corrugated boxes, but surface condition still matters. Clean, dry cartons and firm application pressure give better sealing results. If cartons are dusty, damp, or heavily coated, sample testing before bulk use is recommended to check adhesion and edge lifting.

FAQ

Is opp color tape only used for decoration?

No. Opp color tape is mainly used for carton sealing, warehouse sorting, product identification, and dispatch control. In packing areas, it also works as color coding packing tape for quick visual separation.

Can it stick to recycled corrugated cartons?

Yes. Acrylic adhesive can bond to many recycled corrugated cartons, but the surface should be dry, clean, and free from heavy dust or loose fibers.

Which width is more common for carton sealing?

48mm and 50mm are common choices because they give enough sealing contact for standard carton seams and fit most hand dispensers.

Can different colors be used for different packing rules?

Yes. Different colors can separate urgent orders, inspection status, product groups, warehouse zones, or dispatch routes.
