Custom Interlining — Polypropylene (PP) with Die-Casting
We supply interlining to garment factories and brands, built in Polypropylene (PP) with die-casting for denim and workwear 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 2000 pieces per style per finish.
The failures here are predictable: colour drift between the approved sample and the bulk trim, or unclear responsibility when a defect shows up after washing. We lock material, finish, dimension and tolerance before bulk, and prepare CPSIA and California Prop 65 compliance so the shipment clears instead of sitting at port while your selling season passes.

How we produce it
- Drawing or reference sample review, with size and finish confirmed
- Material selection and a finish sample or strike-off
- Prototype made to the agreed weight

- Bulk run with die-casting applied under controlled settings
- 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 OEKO-TEX Standard 100 for dyes and trims are prepared for the destination market. We ship to Los Angeles or New York 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.
FAQ
Which compliance documents do you provide?
We prepare OEKO-TEX Standard 100 for dyes and trims and the supporting test reports for the destination market.
Can you do small runs across many designs?
Yes — many studio and boutique programmes run small quantities across a wide design set.
Can you match a reference sample?
Yes. Send the trim and we match material, finish and shade, then confirm on a pre-production sample before bulk.
How long does sampling take?
A first sample takes 12 working days, and each revision about 4 days.
