Power Adhesives Tecbond 351B EVA Hot Melt for High-Speed Packaging

Tecbond 351B Fast Setting Biodegradable EVA Hot Melt Pellets

Power Adhesives Tecbond 351B is a biodegradable, EVA-based bulk hot melt adhesive engineered for fast-setting performance in high-speed packaging lines. It runs cleanly through bulk hot melt systems thanks to its low viscosity, reducing downtime from nozzle blockages and ensuring smooth application during long production runs. With high molten tack, low odor, and exceptional heat stability, Tecbond 351B is ideal for case sealing, tray assembly, packaging inserts, and point-of-sale displays. It bonds paper and cardboard substrates reliably in both warm and cool ambient temperatures, and is FDA 175.105 compliant for indirect food contact in food and beverage packaging.

Common Applications of Power Adhesives Tecbond 351B

• Case and Carton Sealing: Creates strong, consistent bonds for high-speed packaging operations.
• Tray Assembly: Maintains integrity with complex folds and varied packaging substrates.
• Packaging Inserts: Secures inserts during shipping to prevent product movement.
• Point-of-Sale Displays: Provides clean, reliable bonds without affecting presentation.
• General Packaging: Performs dependably across a wide range of paper and cardboard applications.

Biodegradable Advantages

Containing 45% bio-based content, Tecbond 351B offers an environmentally responsible option for bulk hot melt applications. It meets the following recognized environmental certifications:

• ASTM D6400
• ASTM D6866
• ASTM D6954
• EN13432

Under controlled industrial composting, exposure to heat, oxygen, and UV light initiates the breakdown process. Once the adhesive’s polymer chains are reduced, naturally occurring microorganisms complete the cycle without creating microplastics or other harmful residues.

For maximum shelf life and performance, keep Tecbond 351B in its original sealed packaging, stored below 86°F (30°C) and away from direct sunlight.

Notable Features of Biodegradable Tecbond 351B

• Certified Sustainable: Meets EN13432, ASTM D6400, ASTM D6866 and ASTM D6954 standards, breaking down in industrial composting without leaving microplastics.
• FDA 175.105 Compliant: Approved for indirect food contact packaging applications.
• Fast-Setting EVA Formula: Ideal for rapid bonding in high-speed packaging environments.
• Low Viscosity Flow: Reduces application equipment blockages and ensures consistent adhesive delivery.
• High Molten Tack: Offers immediate grip for secure material positioning.
• Heat Stable: Maintains integrity during extended molten periods without degrading or charring.
