Custom Interlining in Polypropylene (PP) with Ultrasonic Welding for Childrenswear and Schoolwear

Custom Interlining — Polypropylene (PP) with Ultrasonic Welding

We supply interlining to garment factories and brands, built in Polypropylene (PP) with ultrasonic welding for outerwear and jacket programmes. On a trim like this the specification that decides the outcome is hand feel after fusing, which the customer feels first, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 500 pieces per style per finish.

The failures here are predictable: inconsistent sizing between production runs, or a finish that tarnishes or rubs off after washing. We lock material, finish, dimension and tolerance before bulk, and prepare SNI or SIRIM documentation per destination so the shipment clears instead of sitting at port while your selling season passes.

How we produce it

1. Drawing or reference sample review, with size and finish confirmed
2. Material selection and a finish sample or strike-off
3. Prototype made to the agreed weight
4. Fit and wash test on the actual garment fabric, then a pre-production sample
5. Bulk run with ultrasonic welding applied under controlled settings
6. In-line inspection, final AQL 2.5 inspection and packing to your ratio

Where it is used

• Denim and workwear — hard-wearing finishes that survive industrial washing
• Outerwear and tailoring — matched to the shell fabric so it drapes with the garment
• Childrenswear and schoolwear — tested to the destination's safety standard
• Bridal and eveningwear — small runs with hand-finished detail
• Uniform and corporate programmes — repeatable spec held on file for reorders

Packing, testing and delivery

Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for CPSIA lead and phthalate testing are prepared for the destination market. We ship to Jakarta or Port Klang with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same hand feel after fusing.
