I need to source fully printed HVAC duct tape that carries our company logo across the entire roll. The tape must deliver high adhesive strength so it can maintain an airtight seal on galvanized steel and flexible ducting without lifting over time. Scope • Identify manufacturers or converters capable of producing custom-printed HVAC duct tape in standard 48–50 mm widths. • Confirm print method (full-surface logo repeat) and colour fidelity against our supplied vector artwork. • Provide adhesive performance data demonstrating high tack and shear suitable for HVAC applications; temperature and moisture resistance are desirable but not mandatory. • Submit pricing tiers, minimum order quantities, sample lead time, full production lead time, and available sh...

The goal is to formulate a shelf-stable liquid that behaves like cow's/Buffalo's milk when run through standard milk-testing analyzers, yet contains no perishable dairy components. The solution must be tunable so that I can call for any value within these working windows: • Fat: 2.5 % – 12 % • SNF: 6.5 % – 10 % • Protein: 3 % – 6 % Accuracy should match typical calibration-grade samples (±0.05 % for fat, ±0.1 % for SNF and protein) and hold that performance for at least six months at room temperature. Key considerations The mimic has to flow, foam and disperse pigments just as fresh milk does, without clogging or coating optical or ultrasonic sensors. Viscosity, density and dielectric properties therefore need to si...

Help finding a manufacturer(custom) for a certain product

I’m refining a food formulation that must remain 100 % EU Organic compliant while moving from benchtop trials to a clean, well-documented pilot batch. My top priority is maintaining impeccable hygiene throughout production—recipes, SOPs, and any equipment recommendations must reflect that. Here’s what I need from you: • Review and, if necessary, tweak the current formula so it stays stable and meets EU Organic regulations. • Translate lab-scale quantities into a clear, scalable process flow (ingredient prep, critical control points, hold times, etc.). • Draft concise hygiene SOPs tailored to the proposed equipment line, highlighting surfaces, sanitation cycles, and allergen separation. • Prepare a pilot-batch protocol (yield ≈ 25&ndas...
