Translation guide
Corflute is a brand name for corrugated plastic sheeting, often used for signs, packaging, and temporary structures. In Japanese, it is commonly referred to by the generic term プラダン (pura-dan) or the full phrase プラスチックダンボール (purasuchikku danbōru).
Referring to the material itself, regardless of brand.
Abbreviation of プラスチックダンボール. This is the most common and natural way to refer to corflute in Japanese. Used in DIY, signage, and packaging contexts.
ホームセンターでプラダンを買ってきた。
I bought some corflute at the home center.
This sign is made of corflute.
The full term, literally 'plastic cardboard'. More formal or explanatory. Used when clarity is needed or in technical descriptions.
プラスチックダンボールは水に強い。
Plastic cardboard is water-resistant.
Direct transliteration of the brand name 'Corflute'. Rarely used; most Japanese speakers will not understand this. Only appropriate when specifically referring to the brand in a business context.
Avoid using this unless you are certain the listener knows the brand. Use プラダン instead.
コルフルートというブランドのプラダンを使っています。
We use corflute from the Corflute brand.
Referring to a sign or board made of corflute, such as real estate signs or election posters.
Literally 'corflute sign'. The most natural way to specify a sign made of this material.

Corflute election signs are standing everywhere.
More descriptive, 'plastic corrugated board'. Used in industrial or purchasing contexts.

In almost all everyday situations, プラダン is the best word for corflute. It is widely understood and used in hardware stores, online shops, and DIY communities.
Using コルフルート will likely cause confusion. Even in business settings, Japanese companies usually use プラダン or プラスチックダンボール unless specifically dealing with the Corflute brand.
