Sleeves

Sleeve Types

We offer three different types of sleeves. The sleeves available for each portfolio is shown on the product pages.

Polyester Sleeves

Polyester sleeves are an ultra-clear type of sleeve, especially suited for photography and have a more professional feel to them. They have a slight gloss finish.Polyester sleeves are open on three sides. This means that they are made from a single sheet of polyester which is folded on the 'outside' edge. The rings form the 'inside' edge and the images can be mounted on the black paper provided before putting them in.Because they are shaped this way there is no margin for the holes which makes the sleeves more streamlined.Polyester sleeves are archival quality and can be used for long term storage.

Polyester Sleeves

Cristal Laser Sleeves

Cristal Laser sleeves are made by Prat for their portfolios. They are clear without any texture on the sleeve, but are not a clear as the polyester sleeves. They have a more matt finish to them.They are more robust and better suited to frequent handling than the polyester sleeves and do not show up fingerprints as much. These sleeves are only open at the top, where you can slide your work in. This means that the holes are slightly reinforced and are on a margin on the side.Cristal Laser sleeves are archival quality and are suited to long term storage.

Vinyl/PVC Sleeves

These sleeves are the most robust of all and made from thicker PVC to withstand frequent handling. They have a slight texture on the surface and are not as clear as the other sleeves. They open at the top where you can slide your work in. These sleeves are not usually archival and so not suited to long term storage.

Side By Side Comparison

The pictures below show the same photograph in polyester sleeves (left) and Cristal Laser sleeves (right).

As you can see, the image is slightly clearer in the polyester sleeves. Blacks show through better and there is more contrast between the shades. The surface is also more glossy, so there is slightly more reflection.You can also see the difference between how the holes are constructed. On the Cristal Laser sleeves you can see that the holes are on a black strip on the left of the image, whereas on the polyester sleeve the holes are on the sleeve and there is no separate strip.

Archival Quality

If a product is listed as is archival it means that it is as close to being acid-free as is possible. This also means it will have a neutral PH. Almost nothing can be 100% acid free because as soon as it is touched some acid will be introduced to the product. There are no industry standards for defining archival or acid free. The benefits of using products that have a neutral PH are that they will have a longer permanence, this means they will not discolour or become brittle over time.It also means that the product is suitable for longer term storage and presentation.

Open on 3 Sides v. Open on 1 Side

Polyester sleeves are open on three sides. This means that they are made from a single sheet of polyester which is folded on the 'outside' edge. They contain a piece of black paper for mounting onto.Because they are shaped this way there is no margin for the holes which makes the sleeves more streamlined. All other sleeves are open at the top. Images will not fall out unless you hold it upside down. This has two disadvantages.The first is that to get work out you need to reach inside the sleeve to slide it out. With sleeves open on 3 sides the sleeve can simply be folded over the work.The second disadvantage is that the holes are on a separate strip, which resembles traditional ringbinder sleeves this is not some people However on the whole, sleeves open at the top are more robust and suited to more frequent handling, whereas sleeves open on 3 sides give a more streamlined professional look.

Due to the different spacing between holes on the portfolio sleeves each portfolio requires specific sleeves.
