Ultrasonic Glue-Free Biodegradable Corn-Fiber PLA Pyramid Tea Bags (Zero Microplastics) vs. Nylon/PET Mesh & Stapled Paper
Peer-reviewed analytical chemistry studies (McGill University, Environmental Science & Technology) confirm that steeping a single food-grade nylon-6 or PET pyramid tea bag at 95°C releases approximately 11.6 billion microplastics and 3.1 billion nanoplastics into the beverage. YONG FOOD eliminates microplastic liability for wellness and Kampo brands by utilizing 100% plant-derived non-GMO corn-starch PLA (Polylactic Acid) 3D pyramid mesh sealed via 20kHz ultrasonic molecular welding—zero petroleum plastics, zero adhesives, and zero metal staples.

| Botanical Expansion Space | Full 3D Tetrahedral Pyramid (Allows Whole 6A Longan, Goji & Ginger Slices to Unfold) | 3D Pyramid (High Visual Appeal but Plastic Contamination) | Flat Crushed Envelope (Only Fits Dust & Fannings Grade) |
| Pesticide & Heavy Metal Standard | USP <561> 512-Pesticide Screen ND (< 0.01 mg/kg) + Pb < 0.5 ppm | Often Paired with Unscreened Commercial Tea Dust | Unscreened High-Surface-Area Crushed Herbs |
Why Ultrasonic Tag-and-String Welding Matters for EU, Japan, and US Whole Foods Buyers
Even brands that claim biodegradable mesh often fail retail compliance audits because the cotton string and paper tag are glued to the bag with synthetic polyvinyl acetate or heat-seal lacquer. Our high-speed Japanese-standard pyramid packagers weld the PLA filament string and food-ink tag strictly via 20,000 Hz ultrasonic friction—ensuring 100% adhesive-free infusion.
Pilot-to-Commercial Scaling & Workshop Line Calibration (YF-TEA-5GX15)
Procurement teams evaluating Ultrasonic Glue-Free Biodegradable Corn-Fiber PLA Pyramid Tea Bags (Zero Microplastics) vs. Nylon/PET Mesh & Stapled Paper frequently encounter texture drift or syneresis from conventional workshops. Under SOP XY261152, our formulation team balances natural fruit pectin, slow evaporative dehydration, and cold-pressed botanical lipids so finished units maintain structural integrity across 12-month ambient distribution without synthetic stabilizers, gums, or chemical preservatives.
