Is polyethylene plastic archival?

Archival plastic enclosures can be made from polyester, polypropylene or polyethylene. Although polyester is the most inert of the three, it can generate static electricity which attracts dust and is very expensive.

Is polypropylene safe for archival?

Finally there are Polypropylene (PP). This material is considered archival safe as it is chemically stable and as close to PH neutral as technical possible with plastic and does not contain any plasticizers.

What type of plastic is acid-free?

Archival polyester (PET) is also known by the brand names Melinex and Mylar. It is chemically inert with a high tensile strength and chemical and dimensional stability. It is extremely clear and will never yellow or become cloudy, making it ideal for encapsulation where a detailed view of the covered item is desired.

What is the difference between acid-free and archival?

Although most places equate the two terms, “Archival” is equal OR better than “Acid-free” basically… 'archival' implies pH neutral (or less) and 'acid free', in addition to whatever other characteristics intended for the long term life of the artwork.

What materials are acid-free?

Is polypropylene good for storing photos?

Lesser quality photo storage supplies are often made from polyvinyl chloride (PVC, or vinyl). Plasticizers make this compound unstable, and it deteriorates quickly, damaging photos. Instead, look for materials made from one of these inert plastics: POLYESTER (MYLAR), POLYPROPYLENE, and POLYETHYLENE.

Is polyester fabric archival?

You can choose from a variety of archival qual- ity natural and synthetic textiles. The most common and cost-effective natural textiles used in museums are unbleached linen and cotton. Reliable synthetic products include polyester, poly-cotton blends, and acrylic felts.

Is acrylic plastic archival?

Is foam archival?

Not all foamboard is created equal. Artcare Archival Foam board from Bainbridge is the only one that's truly archival. Other foamboards offer an archival surface, while the foam itself gives off gases that can fade, damage and deteriorate your customers' artwork.

Is polyethylene foam archival?

Is plastic cover acid free?

Terms. The term "acid-free" is not used in relation to plastics. The terms "inert" and "stable" are used to describe plastics that can be safely used in preservation.

What plastic can withstand acid?

Teflon (PTFE)

As a synthetic fluoropolymer, PTFE is very non-reactive and has proven to be an exceptionally useful material. Its unique chemical inertness makes it acid-resistant and it is often used in containers and pipework for reactive and corrosive chemicals.
