On quotes and tech packs, badge material is sometimes listed as “TPU” and sometimes as “PVC”. Both are thermoplastic films that can be used in high-frequency (HF) welding, but they are not the same on hand feel, ageing or fabric fit. This guide summarises what sourcing teams should check when choosing between TPU and PVC.
What are TPU and PVC?
TPU (thermoplastic polyurethane) is a flexible, elastic film family. In the right grade it moves with the fabric and is less prone to brittle behaviour in the cold. PVC (polyvinyl chloride) is an alternative film known for a hardness–cost balance. Both can be welded under an HF mould; the difference shows up in the finished badge’s hand, long-term appearance and the brand’s technical specification.
Choice is not only “cheap versus expensive”. Sportswear, workwear and export collections set different expectations for wash, UV and chemical resistance. If the film type does not match those expectations, edge cracking, stiffening or colour shift tend to appear later.
Decision points
- Flexibility and hand: On elastane-rich fabrics or high-movement areas such as sleeves, knees and shoulders, TPU usually stays softer. PVC can feel more rigid; it may give crisp fine lines but can build stress as the garment moves.
- Yellowing and colour stability: On light, white and metallic surfaces, formulation matters. Anti-yellowing TPU grades are common; on PVC, plasticiser and stabiliser quality drive the result. Asking for a UV or ageing check on the sample makes the difference visible.
- Chemical and wash fit: Where industrial wash, dry cleaning or sweat/chlorine exposure is high, film, adhesive and fabric must be tested together. Film type alone is not enough; application parameters also affect durability.
- Brand and regulatory requirements: Some brands restrict PVC in badges or set migrant/halogen expectations. Read the tech pack before ordering; if it is unclear, ask the supplier in writing. Certificate claims should not be stretched without documents.
- Relief depth and detail: Both films take embossing in an HF mould. Deeper relief stiffens the hand; material type amplifies or softens that effect. Judge the finest logo line together with film thickness.
When TPU, when PVC?
On performance sportswear where soft hand and stretch come first, TPU is often the better fit. Where a harder plate feel is acceptable, cost pressure is high and the brand allows PVC, PVC can stay on the table. For export and premium lines, the specification and sample tests decide—do not assume.
For film finish and colour options see Premium TPU film; for the production method see HF printing. A broader film-selection frame is in the TPU selection guide.
Settle these before you ask for a quote
- Which fabric and which area of the garment will the badge go on?
- What wash temperature and cycle count are targeted?
- Does the brand ban PVC or a specific film type?
- Will yellowing be checked on light or metallic colours?
- Direct HF welding, or heat-press application later?
Answering these up front aligns film type and sample protocol, and cuts mould revisions and return risk.
