After sealing a cardboard box with kraft paper tape, why does it still open, tear, or even require repackaging the next day? | Trusted Taiwan-Based Release Liner Supplier – Over 30 Years of Expertise

Before adopting Joypaper Kraft Paper Tape, the customer was using a standard kraft paper tape for carton sealing. However, after cartons were left overnight, some box seals would crack open or the tape would tear, requiring packaging staff to inspect, reinforce, or even completely reseal the cartons the following day. After switching to Joypaper Kraft Paper Tape, the adhesion performance and seal integrity of the cartons improved significantly. Based on the customer's actual usage results, the previous issue of requiring repackaging after overnight storage was no longer observed. This effectively reduced rework, improved packaging efficiency, and enhanced the overall stability of the packing and shipping process.

Customer Improvement Results

Before Improvement

The customer was previously using a standard kraft paper tape for carton sealing. After cartons were stored overnight, some box seals would open due to carton rebound, internal pressure, or insufficient adhesion, resulting in tape tearing, seal splitting, or edge lifting.

To avoid shipping risks, packaging staff had to inspect cartons again the following day and reinforce or reseal them when necessary. This increased labor requirements, packaging material consumption, and shipping preparation time.

Carton seal opening after overnight storage when using standard kraft paper tape

Before: After sealing with standard kraft paper tape, some cartons experienced seal opening or tape tearing after overnight storage.

After Improvement

After switching to Joypaper Self-Adhesive Kraft Paper Tape, the carton seal adhesion and overall sealing stability improved significantly. Based on the customer's actual usage results, carton seals remained intact after overnight storage and no longer required repackaging the next day.

  • Carton seals remained intact after overnight storage
  • Reduced tape tearing and seal splitting
  • Minimized repeated inspection and reinforcement before shipment
  • Reduced labor and time required for resealing cartons
  • Improved packaging efficiency and shipping process stability
