How to choose

Picking the right SUIN dividers and sheet protectors

Five tabs or eight

Five tabs suit a week (Monday to Friday) or one subject split by task; eight tabs suit a whole course load in one binder.

Insertable or adhesive

The 8-tab insertable set takes cardstock labels you can rewrite; the heavy-duty sets use self-adhesive labels.

Pockets

The insertable set has a pocket on both sides of each page; the heavy-duty sets have one slim front pocket for 10 to 15 sheets.

Protectors for what you handle most

Recipes, sheet music and certificates go into protectors; count each as three sheets when you size the binder.

Dividers

How you use our dividers and sheet protectors

A divider is a promise to your future self that the page will be where you left it. Ours are polypropylene, PVC-free and acid-free, pre-punched for any standard 3-ring binder and wide enough to show past letter-size paper.

Choose the 8-tab insertable set if your subjects change each term: the cardstock inserts slide out and take a new name. Choose the heavy-duty 5-tab or 8-tab sets if the binder lives in a backpack: the diamond texture grips, and the tabs keep their shape after months of handling.

The 500 top-loading sheet protectors fit the same binders, with a reinforced strip along the holes and a checkered finish that cuts glare under classroom lights.

Our dividers and sheet protectors are one of five shelves of the SUIN lineup, and all 24 products stand on one list with their prices.

This is general product information. The labels printed on each product and the sources linked from our guides come first.

Library of Congress, The Deterioration and Preservation of Paper: Some Essential Facts. Acids, from the paper itself or from its surroundings, break down the cellulose in paper in the presence of moisture; acids that form in alkaline paper can be neutralized by its alkaline reserve, and good paper kept in good conditions can last hundreds of years.
Library of Congress (NARA Bulletin 95-7), Establishing a National Policy on Permanent Papers. The acid in older papers speeds their decay, the alkaline papermaking process extends paper life by many decades, and permanent paper is defined as paper that lasts several hundred years under normal use and storage.
Library of Congress, Care, Handling, and Storage of Works on Paper. Papers keep best in acid- and lignin-free folders and polyester sleeves, stored cool, dry and out of strong light, with acidic papers kept apart so their acids do not migrate.
U.S. National Archives and Records Administration, General Considerations for Rehousing and Preservation Processes. Plastic boxes and enclosures made of polyester, polypropylene and polyethylene are often stable and inert, and a product containing polyvinyl chloride (PVC) should never be used.
U.S. National Archives and Records Administration, How to Preserve Family Archives (papers and photographs). Ring binders are among the safe album bindings, sleeves and corners should be made of stable plastics such as polyester, polypropylene or polyethylene, and unknown plastics or PVC are materials to avoid.
Library of Congress, Care, Handling, and Storage of Photographs. Suitable plastic enclosures for photographs are made of uncoated polyester, polyethylene and polypropylene, and they let an item be viewed without taking it out of its sleeve.

Questions

Questions about SUIN dividers and sheet protectors

Do SUIN dividers fit your standard 3-ring binder?

Yes. They are pre-punched with three holes for letter-size binders, and the tabs stand out past letter-size paper and most sheet protectors.

How much paper does a SUIN divider pocket hold?

The slim front pocket of the heavy-duty sets holds about 10 to 15 sheets. The insertable 8-tab set has a pocket on both sides of every divider.

Can you relabel SUIN dividers next term?

The insertable 8-tab set comes with a sheet of cardstock inserts. Write the new subject, slide it into the clear tab, and you are done.

Are SUIN sheet protectors safe for photos and certificates?

They are made of acid-free, PVC-free plastic, which does not lift ink or toner from the page inside. Each one has a reinforced strip along the holes.
