HERMA Elasticated Folder A3 — Translucent Dark Green Polypropylene
A3 · 297 x 420 mmPolypropylene (PP)3 interior flapsElastic corner straps
The HERMA 19521 is an A3 elasticated folder made of translucent dark green polypropylene, with three interior flaps and elastic corner straps, for anyone who needs to carry or store loose A3 sheets — drawings, plans, posters, artwork or large-format printouts — without folding them.
HERMA describes the material as rugged, wet-wipeable and hard-wearing. Unlike a cardboard folder, a polypropylene folder does not soften if it gets damp, does not fray at the corners, and can simply be wiped clean, which makes it a good choice for school bags, workshops and sites where documents travel a lot.
Before you order: This folder is sized for A3 (297 x 420 mm). A4 sheets will slide around inside it, and A2 or larger sheets will need folding. If you only file A4, choose an A4 elasticated folder instead.
What's in the Box
- 1 x HERMA elasticated folder A3, translucent dark green polypropylene (article 19521)
- Elastic corner straps already fitted
What It Means in Practice
- A3 drawings and plans stay flat: the three interior flaps fold over the sheets on three sides so nothing slips out of the open edges.
- The elastic corner straps keep the folder closed in a bag or on a shelf — no clips, buttons or Velcro to wear out.
- Translucent green lets you see roughly what is inside and spot the folder quickly among others; for colour-coding by project or subject, combine it with other colours.
- Wet-wipeable polypropylene: marker, dust or a spilled drink can be wiped off with a damp cloth.
What Will Not Work
- It is not a box file or archive box: HERMA does not publish a capacity or spine width, and an elasticated folder is meant for a working set of sheets, not a thick stack.
- It is not waterproof or sealed — the sides are open under the flaps, so it protects against splashes and handling, not against rain or immersion.
- It has no punched holes or ring mechanism, so it cannot be filed in a lever arch file or ring binder.
- It is not opaque: confidential documents remain partly visible through the translucent cover.

Frequently Asked Questions
Will A3 sheets fit without folding?
Yes. The folder is made for the A3 format (297 x 420 mm), so A3 sheets lie flat inside.
How many sheets does it hold?
HERMA does not publish a capacity. It is designed for a working set of loose sheets; for large volumes an archive box or a box file is the better choice.
Can I clean it?
Yes. The polypropylene is wet-wipeable — use a damp cloth.
Singular Expert Insight · Buyer's Guide
Large-format paperwork is where cheap card folders fail first: the corners split and the sheets crease. A polypropylene A3 folder with interior flaps is the simplest fix for architects, technicians, students and anyone carrying artwork. Browse the rest of our
stationery range for A4 folders and filing.
✓ Buy it if you regularly carry or store A3 drawings, plans or artwork and want them flat and protected from handling.
✕ Skip it if you only work with A4 — an A4 elasticated folder is easier to handle — or you need a lockable or waterproof case.
→ Also consider HERMA elasticated folders in A4 for everyday documents, and colour-coded folders when you run several projects in parallel.
