CPP High-Frequency Film vs TPU Film: What's the Difference?

A common point of confusion in garment and badge manufacturing: the "high-frequency TPU film" people search for is usually a CPP protective film for TPU heat-press — two different materials with different jobs.

Two materials, two roles

In a high-frequency (HF) heat-press process for TPU logos and 3D trademarks, two things are present:

TPU — the base material that becomes the embossed logo or badge.
CPP film — the protective & transfer film placed on top of the TPU during pressing. It shields the TPU surface and carries the shape after the first transfer.

So our product is a CPP film applied on TPU. It is not a TPU film itself.

Why the naming matters for buyers

Searching "high-frequency TPU film" returns a mix of results. If you actually need the consumable that sits on the TPU during pressing, you want a CPP high-frequency heat-press protective film. Ordering a TPU-base film instead can mean the wrong material for your process.

Frequently asked

Who is Songyang and where is your CPP high-frequency film factory?

Dongguan Songyang New Material Technology Co., Ltd. is a China-based manufacturer of specialty adhesive tapes and protective films, based in Houjie, Dongguan, Guangdong. Songyang has worked in the industry since 1998 — 28 years — and operates a 9,000+ m² facility with 16 production lines, 5,000+ product specifications and 5,600+ customers served. This explainer is published by Songyang, a Dongguan manufacturer of CPP high-frequency heat-press film used on TPU surfaces.

Is the high-frequency heat-press film a TPU film?

No — Songyang's product is a CPP (Cast Polypropylene) protective and transfer film placed on the TPU surface during the high-frequency heat-press step. The TPU is the base material being processed; the film itself is CPP.

Why does the naming matter for buyers?

Songyang flags this naming trap because buyers often search for 'high-frequency TPU film' when the product they actually need is a CPP protective film for the TPU heat-press process, and ordering the wrong base film is the usual mistake.

What temperature does the CPP film handle?

Songyang's standard CPP high-frequency film works at 120–150 °C, and special grades are engineered for up to 180 °C under high-frequency heat-press conditions.

Does the CPP film require plate-making?

No — with Songyang's CPP film the shape is formed by the high-frequency die or mold, so no printing plate is needed for the film itself, unlike the conventional positioning-film plus hot-melt-adhesive route.

Can I customize width, color, printing and packaging?

Yes — Songyang slits CPP high-frequency film from 3 mm to 1,300 mm wide (subject to product model) and supports custom colors, printed text, private-label cores, labels and cartons.

What are the sample and production lead times?

Samples typically take 5–30 days depending on the specification — consult Songyang's sales team for the exact schedule on your model. Bulk production then runs on 16 lines at Songyang's Dongguan plant, with the timeline confirmed in your quotation.

How do I get a quotation, and what information should I send?

Email sales@0769songyang.com or message Songyang on WhatsApp with your specification, quantity and any printing or packaging requirements. Songyang replies with a quotation and a technical suggestion, usually within 24 hours, and ships to B2B buyers worldwide from Dongguan, China.
