Series note: Part 1 of 2. Part 2 covers performance, on-site use and ordering.

Green PP film faced plywood is one of the fastest-growing formwork products in our range, and it also generates the most questions — mostly around what "PP" actually changes, and how much of the environmental story is real.

Part 1 of this FAQ answers the six material questions we hear most from importers and distributors. Part 2 covers reuse cycles, on-site handling, sizes and ordering.

1. What is green PP film faced plywood?

Green PP film faced plywood is a concrete formwork panel whose surface is coated with a polypropylene (PP) film instead of the traditional phenolic-impregnated paper film.

The panel itself is a standard plywood build: layered hardwood or softwood veneer, bonded with water-resistant (WBP-class) glue, with a durable film hot-pressed onto both faces and the edges sealed with waterproof paint. The difference is entirely in the surface layer — and it changes both the environmental profile and the on-site performance of the panel.

Green is simply the standard colour of PP film. The same panel is also available in grey, black and other colours on request.

2. What is the difference between PP film and traditional phenolic film?

This is the question that decides most orders:

The practical summary: PP film trades a higher panel price for cleaner edges over the panel's life, less release-agent use, and a recyclable surface layer. For projects with waste-reduction targets, that trade is often worth it.

3. Why is the film green?

The green colour is the natural and standard colour of polypropylene composite film — it is not a coating added on top. Grey and black PP films are also produced; green remains the most common because it has become the recognised colour for PP-faced formwork in most markets.

The colour has no effect on performance. Buyers choosing green are typically following project specifications or market convention, not engineering requirements.

4. Is it really recyclable? What makes it "green"?

The environmental claim rests on two points:

1. The film layer is thermoplastic. Unlike phenolic film, which is a thermoset resin that cannot be re-melted, PP film can in principle be reprocessed. At end of life, the film separates from the wood content more cleanly than phenolic film does.

1. No phenol or formaldehyde chemistry in the surface layer. The film itself is emission-free; there is no resin impregnation step.

Be precise about the limits: the whole panel is not automatically "100% recyclable". Recyclability depends on the glue system in the core and the waste-handling infrastructure in the destination market. If a project's green-building documentation requires proof, request the specific test data and material declarations for the exact panel being quoted — not a generic brochure claim.

5. Does it contain formaldehyde?

The film layer contains none — PP film is a polypropylene sheet, with no resin system.

The core, however, is bonded with glue, and that is where the honest answer lives: most PP film faced plywood still uses a WBP phenolic glue line in the core. Panels are also available with lower-emission glue systems on request.

So the correct statement to your customers is: "formaldehyde-free film layer; core glue system available to specification — request the current emission test data for the item you are buying." Do not advertise the whole panel as formaldehyde-free unless the specific panel's documentation supports it.

6. What core and glue options are available?

The film gets the attention, but the core determines how the panel actually performs over its life:

The buying tip that matters: when comparing quotes, match the core and glue line first and the film colour last. Two "green PP film faced" panels with different cores are not the same product, and the price difference between them is usually justified.
