Biodegradable Low Temp Metallocene Hot Melt Adhesive for Automated Packaging

Power Adhesives Tecbond 355B Biodegradable Hot Melt Pellets

Power Adhesives Tecbond 355B is a biodegradable, metallocene-based bulk hot melt adhesive designed for cold storage and automated packaging applications. Engineered for high-speed performance and exceptional cold-temperature reliability down to -22°F (-30°C), it delivers clean-running performance, low char, and excellent thermal stability during long production runs. Tecbond 355B bonds challenging substrates such as lacquered and varnished boards, making it a dependable choice for case and carton sealing, tray assembly, packaging inserts, and point-of-sale displays. Fully FDA 175.105 compliant for indirect food contact, it supports demanding food and beverage packaging operations while promoting sustainable practices.

Common Applications

• Case and Carton Sealing: Fast, secure bonds for high-speed production lines.
• Tray Assembly: Maintains strength with complex folds and coated boards.
• Packaging Inserts: Keeps inserts firmly in place during transit.
• Point-of-Sale Displays: Delivers strong, clean bonds without affecting presentation quality.
• Cold Storage Packaging: Dependable adhesion in environments down to -22°F (-30°C).

Biodegradable Benefits

Tecbond 355B is 45% bio-based and non-toxic, offering a sustainable alternative to standard bulk hot melt adhesives. It has been tested to meet the following certifications:

• ASTM D6400
• ASTM D6866
• ASTM D6954
• EN13432

Biodegradable under industrial composting conditions, Tecbond 355B pellets begin to degrade when exposed to oxygen, UV light, and heat. After the long-chain polymers are broken down, microorganisms consume the remaining material without leaving behind microplastics or harmful byproducts.

To maintain quality and performance, store the adhesive in its original packaging, away from direct sunlight, and at temperatures below 86°F (30°C).

Performance Highlights

• Eco-Conscious Degradation: Meets EN13432, ASTM D6954, ASTM D6866, and ASTM D6400 standards, breaking down naturally without producing microplastics.
• Metallocene-Based Chemistry: Offers clean-running performance, low char, and exceptional thermal stability during extended production runs.
• Cold Temperature Reliability: Maintains strong adhesion in storage environments down to -22°F (-30°C).
• Strong on Difficult Substrates: Bonds reliably to lacquered and varnished boards, as well as other coated packaging materials.
• FDA 175.105 Compliant: Safe for indirect food contact applications.
