Power Adhesives Tecbond 355B Metallocene Hot Melt for Cold Storage Packaging

Tecbond 355B Biodegradable Bulk Packaging Hot Melt

Formulated for sustainability and cold-temperature performance, Power Adhesives Tecbond 355B is a biodegradable, metallocene-based bulk hot melt adhesive built for cold storage and automated packaging applications. Designed for high-speed packaging lines, it delivers clean-running performance, low char, and excellent thermal stability during long production runs, maintaining dependable adhesion even in environments down to -22°F (-30°C). Tecbond 355B bonds coated and specialty boards with precision and strength while minimizing maintenance in bulk hot melt systems, making it ideal for case and carton sealing, tray assembly, packaging inserts, and point-of-sale displays. Fully FDA 175.105 compliant, it supports safe indirect food contact in packaged food and beverage operations while promoting sustainable packaging practices.

Where Tecbond 355B Excels

• Cold Storage Packaging: Reliable performance for refrigerated and frozen goods.
• Tray Assembly: Holds structure in complex folded or coated packaging.
• Case and Carton Sealing: Secure bonds at high speeds with minimal maintenance.
• Packaging Inserts: Protects products by keeping inserts in place during handling.
• Point-of-Sale Displays: Strong, clean adhesion that preserves display appearance.

Biodegradable Properties

Tecbond 355B meets leading environmental certifications, including ASTM D6400, EN13432, ASTM D6954, and ASTM D6866, ensuring compliance with industrial composting and biodegradability standards. Composed of 45% bio-based materials, this adhesive naturally breaks down under oxygen, UV light, and heat. Once the polymer base is degraded, microorganisms consume the remaining material without leaving behind harmful byproducts such as microplastics.

To preserve quality and performance, store Tecbond 355B in its original packaging, away from direct sunlight, and at temperatures below 86°F (30°C).
