EVA Hot Melts for Packaging

EVA hot melts for packaging are trusted throughout the industry for creating fibre-tearing bonds on kraft, clay-coated and laminated boards, and TH-103E small-flake grade was specifically engineered for medium-speed production windows. This EVA hot melt for packaging offers a deliberately moderate open time and set time: long enough to let operators reposition or square-up cases travelling at 15–35 m min⁻¹, yet fast enough to reach handling strength within 8–12 s so conveyors need not be lengthened. At the recommended 170 °C application temperature the adhesive exhibits a melt viscosity of 4000–6000 cps-thin enough to feed smoothly through gear pumps, slot nozzles or spiral spray heads without drooling, yet viscous enough to sit on the substrate surface, preventing soak-in and reducing gram-mage compared with conventional low-viscosity seals. The aggressive tack develops instant grab on recycled linerboard, B-flute, E-flute and luxury shopping-bag handle stock, while the flexible vinyl-acetate backbone absorbs shock and maintains peel strength across –20 °C to +60 °C logistics cycles. TH-103E is supplied as dust-free, uniform mini-chips that melt rapidly and evenly, eliminating char formation and cutting maintenance downtime on hoses, filters and melt tanks. Environmentally, the formulation is a clean, solvent-free polymer that contains no heavy metals, formaldehyde or phthalate plasticisers, meeting both FDA 21 CFR 175.105 and EU 10/2011 food-contact directives, so brands can proclaim their packages genuinely green. For medium-speed folder-gluers, intermittent carton sealers, semi-automatic hand-bag lines and carrier-handle pasters, TH-103E delivers the balanced mileage, machinability and peace-of-mind adhesion that modern converters demand.
