Paper Based Packing Tapes

Paper Based Packing Tapes are manufactured by Yuhong, a packaging materials producer based in Xiamen, China. The product is also referred to as water-activated kraft paper tape, gummed paper tape, or kraft sealing tape. It consists of a kraft paper backing coated with a moisture-reactive starch adhesive. When wetted, the adhesive bonds to corrugated fiberboard and becomes part of the carton surface.

Yuhong water activated tape is commonly used in e-commerce, food logistics, and export packing where carton integrity and tamper evidence are required. It is available in plain or custom printed formats, and it can be applied with manual dispensers or automatic case sealers.

Technical Specifications

Two standard configurations are produced. The first is for general industrial use. The second is for reinforced export packaging and automated lines.

Custom widths and roll lengths can be discussed for volume orders.

Manufacturing and Quality Checks

Yuhong produces Paper Based Packing Tapes in a 3,000 m² facility under ISO 9001:2015 quality management. Annual production capacity is approximately 5,000 tons.

Production steps include:

1. Raw paper selection and slitting. Paper rolls are checked for density and tensile strength before slitting to produce clean edges.
2. Adhesive coating. Automated coating heads apply a uniform starch layer to avoid dry spots.
3. Low-temperature drying. The coated paper passes through drying tunnels that preserve fiber flexibility.

Quality control stages:

• Incoming inspection: kraft paper and starch adhesive are tested for moisture content and tensile strength.
• In-process monitoring: coating thickness is checked every 30 minutes with online sensors.
• Finished product testing: fiber-tear adhesion is verified on corrugated board. The bond should form within five seconds of activation.
• Pre-shipment check: core diameter, moisture-proof packaging, and pallet balance are confirmed.

Application Scenarios

• E-commerce order fulfillment. The matte paper surface accepts handwriting and printed labels without smudging.
• Food and pharmaceutical warehouses. No chemical odor is present, and the tape is safe for indirect food contact packaging.
• Heavy freight. Cartons over 20kg benefit from stronger bottom flap support than standard plastic tape.
• Export container loading. The tape remains bonded under high humidity and temperature swings.

Custom Printing and Private Label

Yuhong prints customer logos, warning symbols, or handling instructions on the paper surface using water-based inks. Up to three colors are supported. Custom core labels and barcodes are available for distributor branding. The factory supports FOB, CIF, and DDP trade terms.

Storage and Activation Recommendations

• Store rolls in original packaging at 10°C to 30°C and 40% to 60% relative humidity.
• Avoid direct contact with water before use. Moisture will activate the adhesive prematurely.
• Recommended activation water temperature is 15°C to 25°C. Very cold water slows adhesive activation; very hot water may cause excessive wetting.
• For manual dispensers, adjust the brush or sponge to apply an even water film. Too much water can weaken the paper backing; too little water results in poor adhesion.
• Allow the tape to set for 5 to 10 seconds after application before moving the carton. Full bond strength develops as the adhesive dries.

Frequently Asked Questions

1. How do I activate the adhesive on this tape?

The adhesive is moisture-reactive. Wet the adhesive side with a sponge, brush, or automatic moistening system on a dispenser. The tape should be applied to the carton within a few seconds. The bond forms as the starch adhesive penetrates the cardboard fibers and dries.

2. Will the tape stick if the carton is dusty or stored in a humid warehouse?

Yes. The starch adhesive penetrates surface dust and bonds to the paper fibers underneath. Once dry, the bond is not affected by ambient humidity. This is a key difference from plastic tape, which relies on a clean, dry surface.

3. Can this tape be used with automatic case sealers?

Yes. Reinforced export grade rolls are produced in lengths up to 1,000 meters for automated equipment. The paper backing is strong enough to withstand the tension of high-speed case sealers. Yuhong can provide roll specifications to match your machine.

4. Is the tape really tamper-evident?

Yes. Attempting to remove the tape after drying will tear the carton surface. This leaves visible damage and makes unauthorized opening obvious. For high-security applications, reinforced tape with fiberglass scrim provides additional resistance.

5. What is the minimum order quantity for custom printed tape?

Standard plain rolls can be ordered in smaller quantities. Custom printed tape usually requires a minimum of 1,000 rolls because printing plates and coating machine adjustments are needed. Contact the sales team to confirm the current MOQ for your design.

6. Can I get a sample before placing a bulk order?

Yes. Sample rolls are available. You can test the tape on your cartons and with your dispensing equipment. The sample shipping cost can be deducted from the first formal order.
