Custom Sewing Thread — Polyethylene (PE) with Injection Moulding
We supply sewing thread to garment factories and brands, built in Polyethylene (PE) with injection moulding for childrenswear and schoolwear. On a trim like this the specification that decides the outcome is shade continuity across cones in one bulk lot, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 3000 pieces per style per finish.
The failures here are predictable: inconsistent sizing between production runs, or packing that arrives mixed and unusable on the line. We lock material, finish, dimension and tolerance before bulk, and prepare UKCA and REACH documentation so the shipment clears instead of sitting at port while your selling season passes.

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 GRS recycled content claim are prepared for the destination market. We ship to Felixstowe 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 shade continuity across cones in one bulk lot.
FAQ
How do you control colour on reorders?
The approved reference and the bulk standard are retained, and every reorder is checked against them before shipment.
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.
What packing options are available?
Bulk packed, carded, or packed to your own size and design ratio with barcodes applied.
How long does sampling take?
A first sample takes 7 working days, and each revision about 3 days.
