Sanlei’s TPD-compliant disposable E cigarettes are lessen the ecological toll usually associated with single-use devices. Instead of the industry-standard welded shell, Sanlei uses a snap-apart aluminium chassis that can be separated from the internal electronics in seconds, making battery, circuit board and e-liquid reservoir accessible for dedicated recycling streams. The 400 mAh cell is a high-density lithium-iron variety that contains 30 % less cobalt than typical vape batteries, reducing reliance on scarce, environmentally damaging metals . A thin food-grade PCTG tank holds only 2 ml—precisely the TPD limit—so no excess plastic is produced per puff. The entire assembly ships in a kraft box printed with water-based inks and sealed with a single cellulose sticker, eliminating the mixed-film blister packs that often contaminate paper recycling.  By merging strict TPD safety with deliberate end-of-life planning, Sanlei provides customers with environmental sustainability products and high-quality services.
