The 100% Degradable Solution for Heavy Logistics: A Closer Look at KN-37120E

In the world of industrial packaging, there has historically been a rigid trade-off between sustainability and strength. If you needed to seal a heavy, overstuffed carton for export, you used fiberglass-reinforced tape because it was the only material strong enough to survive the journey. However, the KN-37120E (often inquired about as the 37120 series) fundamentally challenges this limitation. As listed in our technical specifications, this model is a Heavy Duty Reinforced Water-Activated Tape that is 100% degradable. It eliminates the non-recyclable fiberglass mesh found in traditional tapes and replaces it with a robust network of plant-based yarn, allowing high-volume logistics centers to maintain their heavy-duty sealing standards while achieving zero-plastic waste goals.

The engineering behind the KN-37120E is what sets it apart from standard eco-friendly tapes, which are often relegated to light-duty applications. According to our technical data sheet, this tape is constructed with a substantial paper backing composition, combining a 40g/m² top layer with a 70g/m² bottom layer. This dual-layer kraft structure provides the necessary physical bulk and puncture resistance required for heavy industrial handling. Inside this paper "sandwich" lies the critical innovation: a high-density reinforcement grid made entirely of plant-based yarn. We utilize 600D (Denier) yarn in the machine direction (MD) and 200D yarn in the cross direction (CD). This 600D rating in the longitudinal direction is significantly thicker and stronger than the yarn used in our lighter degradable models (like the JLN-3150E, which uses 300D yarn), giving the KN-37120E the tensile power needed to bundle pipes, heavy auto parts, or bulk textiles without snapping.

From an operational perspective, switching to the KN-37120E does not require a change in machinery or process. It utilizes the same starch-based adhesive system as our standard tapes , which activates immediately with water to form a permanent, tamper-proof bond with the carton fibers. The difference is purely in the end-of-life cycle. When a customer receives a box sealed with KN-37120E, they do not need to separate the tape from the cardboard for recycling. The entire package—box and seal—is mono-material and fully repulpable. For brands looking to make a serious commitment to sustainability without risking product damage during heavy transit, the KN-37120E proves that plant-based materials are ready for the heavy lifting.
