custom printed kraft tape
Foshan Opalus Adhesive Products Co., Ltd. is a manufacturer of custom printed kraft tape for branded carton sealing, paper-based shipping, and recyclable carton packaging. Made with kraft paper backing, the tape can be produced with a brown kraft surface for a natural carton look or a white kraft surface for sharper logo contrast. Self adhesive and water activated versions are available to match carton grade, artwork coverage, roll width, and packing-station use.

Product Overview
This printed kraft paper tape is made for cartons that need secure sealing and visible brand identification at the same time. The paper backing keeps the seal close to the carton surface, while the printable face can carry logos, product codes, QR codes, warning text, or repeated artwork across the carton seam. For packaging teams moving away from plastic-looking tape, the kraft paper structure gives shipping boxes a cleaner and more coordinated appearance.
Brown kraft is usually chosen for natural, recycled, or simple packaging designs. It works well with black, dark green, navy, or other low-color artwork. White kraft is more suitable when brighter colors, smaller text, barcodes, QR codes, or handling messages need stronger contrast. During sample approval, print repeat length, ink coverage, print direction, kraft paper gsm, and color proof should be checked together to avoid poor logo spacing or color mismatch in repeat production.
The adhesive should match the sealing method. Self adhesive kraft tape uses pressure-sensitive adhesive and bonds after firm contact with the box surface. It is convenient for hand packing, tape guns, mixed carton sizes, and short-run packaging. Water activated kraft tape uses a moistened adhesive system, normally starch-based, and is activated before application for stronger paper-to-paper bonding. Recycled boxes may carry dust or rough fibers, so initial tack, peel adhesion, and carton seam holding should be checked on the actual carton grade.
Benefits
- Converts the carton seam into a printed brand area without adding a separate label.
- Kraft paper backing gives the package a paper-based look that matches corrugated cartons.
- Brown kraft surface supports natural, recycled, and low-color packaging styles.
- White kraft surface improves logo contrast, QR code visibility, and small text clarity.
- Self adhesive structure suits hand sealing, tape guns, and mixed carton sizes.
- Water activated structure supports stronger wet-out bonding when moisture and setting time are controlled.
- Paper gsm, print repeat length, ink coverage, and artwork direction can be adjusted around carton size.
- Sample rolls can be tested for tack, peel adhesion, tensile strength, color proof, seam holding, and repeat batch consistency.
When Should Self Adhesive Kraft Tape Be Selected Instead of Water Activated Kraft Tape?
Self adhesive kraft tape is a good choice when a packing area needs fast sealing without water, sponge pads, or water-activated dispensers. The pressure-sensitive adhesive bonds after the tape is pressed firmly onto the carton, so it fits light to medium shipping boxes, subscription cartons, retail parcels, and short-run branded packaging. For recycled cartons, surface dust and paper roughness should be reviewed before approval because adhesive contact directly affects initial tack and peel performance.

How Can Brown and White Kraft Surfaces Affect Printed Packaging Results?
Brown and white kraft surfaces do not show artwork in the same way. Brown kraft gives a softer, more natural print result and works well when the package should look simple, recycled, or carton-matched. It is usually better for dark single-color logos or short printed messages. White kraft gives stronger contrast, so it is more suitable for brighter artwork, smaller text, warning messages, QR codes, and repeated brand patterns. Since kraft paper is not a coated plastic film surface, ink can absorb slightly into the paper. For repeat batches, artwork direction, print repeat length, ink coverage, paper gsm, approved color samples, and retained production samples should be confirmed before production.
FAQ
What is custom printed kraft tape used for?
It is used for branded carton sealing, e-commerce packaging, retail shipping boxes, subscription cartons, and warehouse packing. The tape combines kraft paper backing with printed logos, text, or handling messages so the carton seal also supports package identification.
Is self adhesive kraft tape or water activated kraft tape better?
Self adhesive kraft tape is easier for hand packing and small to medium carton volumes because it does not need water activation. Water activated kraft tape is better when stronger carton fiber bonding, wet-out control, and a more secure paper-to-paper seal are required.
Can the tape be printed on both brown and white kraft paper?
Yes. Brown kraft is suitable for natural carton-matched packaging and dark single-color artwork. White kraft is better for brighter logos, clearer small text, QR codes, and higher-contrast printed packaging. A color proof should be confirmed before bulk production.
What should be tested before approving bulk production?
Before approval, test the tape on the actual carton grade. Important checks include paper gsm, total thickness, peel adhesion, initial tack, tensile strength, ink coverage, print repeat length, carton seam holding, dispenser compatibility, storage condition, core size, and retained sample consistency.
