Baby Pull-Up Training Pants (Step-In Baby Pants)
Shenghongda manufactures high-speed converted baby pull-up training pants engineered for toddlers in active developmental stages and potty-training transitions. Built with an ultrasonic-bonded 360-degree soft bubble waistband containing over 40 individual lycra strands, our training pants provide continuous tension without marking sensitive abdominal skin. The ultra-thin Japanese Sumitomo SAP core absorbs moisture within 2.3 seconds, holding up to 800-1,100 ml while maintaining a flat, unbulked profile between the toddler's legs. After voiding, parents can easily tear the ultrasonic side seams for clean removal, roll the pant into a compact bundle, and secure it with the integrated adhesive disposal tape on the backsheet. Available with hot-air nonwoven embossed liners, plant-based chamomile or aloe skin protectants, and customized cartoon backsheet graphics. Sizes include M, L, XL, XXL, and XXXL with an MOQ of 50,000 to 160,000 units, FOB $0.04 to $0.07, loading 350,000 pieces per 40HQ container.
