Visible TPU face
Mark the finished outline, raised and recessed zones, color breaks, readable details and orientation. A front rendering cannot prove what exists on the reverse.
A TPU patch is only one layer in a finished garment system. This guide separates the visible logo, reverse construction, attachment route, textile and production trial so buyers can request evidence for the exact SKU instead of assigning a generic sew-on, heat-applied or adhesive label to every flexible patch.

Begin with five records rather than one product nickname. The face defines color, relief and shape; the reverse carries the supplier-confirmed attachment construction; the receiving textile contributes stretch, texture and finish; the placement introduces seams and access constraints; the production process applies the selected route. A decision is supportable only when those records refer to the same sample revision.
Mark the finished outline, raised and recessed zones, color breaks, readable details and orientation. A front rendering cannot prove what exists on the reverse.
Request a labeled back view and written construction statement for the quoted SKU. Do not infer a heat film, pressure-sensitive layer or sewing margin from a similar catalog image.
Identify product style, fabric composition, coating, texture, thickness, stretch direction and the exact application zone. These facts determine what the trial must represent.
The database contains three useful construction references, each with a recorded minimum order quantity of 100 pieces. They illustrate why the exact product record matters: related appearances can carry different material descriptions and dimensions. Final color, reverse, tolerances, attachment and availability still require written confirmation for the quotation.
Material: TPU
Reference size: 7.5 cm
Recorded MOQ: 100
Use this soft-rubber-logo reference to discuss face relief and outline, while keeping its unrecorded backing outside the claim.
Material: TPU silicone
Reference size: 5 cm
Recorded MOQ: 100
Its combined wording must be preserved in the brief rather than simplified into a different compound.
Material: TPU and silicone
Reference size: 5 × 3 cm
Recorded MOQ: 100
The catalog title mentions adhesive backing, but the current order must still confirm the supplied reverse and intended use.
A controlled reverse record should show the entire perimeter, any carrier or liner, the surface that meets the garment and a label tying the photograph to the quotation. Request the nominal patch thickness and edge construction when either affects a stitch path or press contact. If the reverse changes after the sample, issue a new revision instead of treating the change as invisible.
For heat-assisted proposals, obtain the SKU-specific application direction in writing. For sew proposals, obtain confirmation that the intended needle route is acceptable. For an adhesive request, define the job and ask the supplier to identify whether the proposed layer is for positioning or final retention.


Two garments with the same fiber label can behave differently because of knit structure, coatings, padding, dye, texture or seam construction. Photograph the placement at true scale and measure it from a stable landmark. Note whether a platen or sewing head can reach the area without trapping a pocket, lining or internal reinforcement.
The trial should answer a narrow question about one patch revision and one representative substrate. Do not mix several backings or garments in an unlabeled test sheet. When a result changes, preserve both observations and identify the variable that changed.
Verify project code, patch dimensions, face, reverse, quantity and supplier instructions before any assembly attempt.
Record operator, equipment, fixture or platen, protective layers and the complete sequence used for the candidate method.
Examine alignment, face distortion, perimeter contact, stitch appearance and surrounding fabric under consistent light.
State accepted, revise or rejected; attach photographs and restrict approval to the tested construction and garment.
Care or handling evaluation should follow the buyer's defined protocol and the garment supplier's limitations. Report observations from that protocol rather than converting a limited sample into a broad lifetime or wash guarantee.
A release ledger prevents a visually approved face from being mistaken for a complete assembly approval. The buyer, supplier and application team should be able to identify the same patch, reverse, garment, route and sample without interpreting a message thread.
| Controlled field | Evidence to retain | Release question |
|---|---|---|
| Patch revision | Face proof, dimensions and labeled sample | Is this the exact quoted artwork and size? |
| Reverse construction | Back image and supplier statement | Is the selected method supported for this SKU? |
| Garment interface | Style record and placement photograph | Does the trial represent production? |
| Process | Equipment sequence and operator log | Can the accepted procedure be repeated? |
| Inspection | Dated observations and approval owner | What was accepted and what remains conditional? |
