Line 02: 15g×10 4-Layer Oil-Barrier Foil Nitrogen-Flushed Botanical Paste Stick Pack OEM (YF-STICK-15GX10)
Traditional botanical pastes cooked in cold-pressed black sesame oil rapidly delaminate standard 3-layer plastic sachets due to free fatty-acid migration into the adhesive layer.

Solving Cold-Pressed Black Sesame Oil Delamination in Single-Serve Liquid Supplements
When formulating authentic Eastern warming tonics with first-press black sesame oil and Yunnan Luoping small yellow ginger, standard polyurethane adhesives and polyethylene sealant films swell and peel within 30 days. Our RCPP35 (Retort-Grade Cast Polypropylene) inner layer paired with solvent-free oil-resistant curing adhesive withstands 85°C hot-filling and 15 kgf compression load testing without a single micro-leak.
