Acid-free archival boxes
Correx® is increasingly used for museum storage boxes, being cost-effective if you have a requirement for long-term storage or preservation of valuable items.
Museum storage boxes are specialist, archival-quality containers that preserve and protect their contents from environmental damage, pests, dust, humidity, and mishandling. Correx® boxes are also acid- and lignin-free, preventing yellowing and brittleness. Museums, universities, and similar organisations commonly use Correx® acid-free archival boxes to protect documents, photos, textiles, and artefacts.
At GWP Correx, we design museum archive boxes to the exact size, strength or specification you need, with our in-house team and manufacturing capability allowing us to provide a huge range of bespoke options.

What our customers say...

GWP provided an excellent solution, with the storage boxes being strong, durable, and protecting the contents from water and dust. Supplying these boxes means our community can benefit for years to come.
Elaine Dent | President | Peacock WI

An efficient, friendly, easy to deal with team of people. We have stayed with GWP because the service is so good. We buy thousands of boxes each year, plus foam and division sets. The bespoke items are always good, and the design team is excellent.
John Wayman | Managing Director | Bondline

We previously used cardboard but needed something more robust and with better performance around water. GWP supplied us with company branded Correx boxes to transport water samples back to the lab. Lead time and price were both excellent. The team and service was quick, reliable, helpful and friendly.

FAQs
Are Correx® boxes more suitable for museum storage than cardboard?
Whilst cardboard archive boxes are a low-cost option, Correx® storage boxes offer several benefits. These include being more durable and hardwearing, acid-free, water-resistant, non-shedding (i.e., do not create dust/fibres), and generally offering higher levels of protection.
What are acid-free boxes?
Acid-free boxes are used for long-term preservation, as they prevent acidic degradation, yellowing, and brittleness in valuable documents, photos, textiles, and artefacts. Unlike standard corrugated cardboard, Correx® boxes are acid-free, making them ideal for museum conservation. Correx® is also inert, unreactive, resistant to water, dust, grease, and chemicals, and easy to clean.
What are lignin-free boxes?
Lignin is a natural polymer (the second most abundant natural polymer on earth, after cellulose) that is found in plant cell walls. However, its presence in paper and corrugated cardboard can cause yellowing and brittleness when used for long-term storage and preservation. Correx® boxes contain no lignin, making them suitable for the safe storage of museum artefacts.
What sizes are Correx® storage boxes available in?
It is possible to manufacture Correx® archive boxes to the exact size you require. This dimensional flexibility means that if you have unusually shaped or sized items, you can source storage boxes that are a perfect fit. Bespoke-sized Correx® storage boxes can also help maximise the available space in your storage facility.
Can my museum storage boxes include dividers or inserts?
You can enhance any Correx® museum storage box with a range of dividers, layer pads and inserts. These can help separate items during storage, keeping them organised and better protected during handling. You can also use special materials such as foams, or anti-scuff or cushioning Bubbleboard, to protect delicate surfaces.
