The dining table is covered in offcuts of clear plastic film. One exercise book has three visible air bubbles across the front cover. Another has a crooked spine line. This can be a frustrating part of getting school books ready for the new year, especially when several books need covering. 

This guide breaks the process down clearly for both contact and slip-on covers, with a focus on avoiding the bubbles that make the job frustrating. It is part of our notebooks and paper for school guide.

Quick answer

Contact paper provides a permanent protective cover when applied correctly, but it takes practice to avoid bubbles and creases. Slip-on covers are quicker, reusable and need no adhesive, although they depend more on getting the correct size. Most bubbles come from rushing the peel-and-press step rather than from the contact itself. 

Why Schools Ask for Covered Books

Some Australian schools ask students to cover their books, and covering requirements may appear on the school booklist. The reasons are practical:

• It protects covers from spills, scuffing and general daily wear.
• It helps students, especially younger ones, identify their own book quickly in a stack.
• It lets families personalise plain exercise books, which some children enjoy.

If the booklist does not specify a covering method, either contact or slip-on generally works. If it does specify one, follow that instruction, since some schools prefer a particular type for consistency across a class.

Contact vs Slip-On Covers Compared

Neither option is universally better. The right choice depends on how much time you have, how many books need covering, and whether the school has a preference.

What You Need Before You Start

Getting set up properly avoids most bubble problems before they start.

• A clean, flat, hard surface, such as a dining table or bench.
• Contact paper or slip-on covers sized to the book.
• Sharp scissors and a ruler for straight edges.
• A soft cloth or a plastic smoothing tool, such as an old gift card.
• Good lighting, so bubbles are visible while you work, not after the fact.

Key note: Wipe the book cover clean and dry before you begin. Dust or moisture trapped under contact paper creates a permanent bump that no amount of smoothing will fix later.

Choosing the right notebook to begin with also matters. A Bibbulmun Everyday A4 Wiro-Bound Notebook has a flat cover panel that provides a straightforward surface for contact covering. 

Covering With Contact, Step by Step

1. Lay the book face down on the back of the contact sheet. Leave an even border of a few centimetres on every side.
2. Trim the sheet to size, keeping the border consistent.
3. Peel back a small section of the backing, starting at the spine. Only peel a few centimetres at a time. This is the single biggest factor in avoiding bubbles, since peeling the whole backing off at once makes it almost impossible to lay the film down evenly.
4. Press the exposed sticky section onto the spine first. Line it up straight before moving outward.
5. Continue peeling a little at a time, smoothing as you go. Work from the centre outward toward the edges, using your hand or a smoothing tool to push out any air ahead of where you press down.
6. Fold the excess over the edges and corners. Snip a small triangle at each corner before folding, which allows the film to sit flat rather than bunching.
7. Smooth the whole cover one more time from the centre out, checking for any missed bubbles before moving to the next book.

Key note: Working slowly through the peel-and-press step matters more than any other single factor. Most bubbles form because the backing was removed too quickly, leaving no opportunity to lay the film down evenly before it sticks.

Fixing a Bubble After It Happens

A small bubble does not mean starting over.

• For a small bubble, gently lift the nearest edge of film and smooth it back down, working the air toward the edge.
• For a bubble that will not shift, a fine pin prick lets trapped air escape. Press gently from the centre of the bubble outward to release it through the hole, then smooth flat.
• For a larger stubborn bubble, briefly warming the film with a hairdryer on a low setting may soften the adhesive enough to lift and reseat that section. Avoid overheating the cover or book. 

This is far easier on a fresh cover than on one that has already fully bonded, so check for bubbles as you go rather than waiting until the whole book is covered.

Slip-On Covers, Step by Step

Slip-on covers are simpler, though correct sizing is the key skill.

1. Check the book's exact size against the cover's label. A cover made for a slightly different size will not sit flat.
2. Slide the front cover into the sleeve pocket first, then work the back cover in.
3. Smooth the sleeve into place, checking the spine sits centred rather than skewed to one side.
4. Trim any excess if the cover allows it, following the manufacturer's instructions.

Slip-on covers avoid the bubble problem entirely, since there is no adhesive step. Their main weak point is fit. A loose cover can slide during the year, so checking the size carefully before buying saves a return or ill-fitting cover later.

Choosing Contact Thickness and Film Type

Not all contact paper performs the same. Thinner film is more prone to tearing over a full school year of handling, while a heavier film holds up better under daily use. A heavier film may provide better resistance to tearing and everyday wear, so it can be worth comparing thickness as well as price when choosing a cover for a book used every day. 

Clear film is the most common choice for a clean, simple finish, and it lets any name label or decoration underneath remain visible. Patterned or coloured film can also work well, and busier patterns tend to disguise small imperfections better than a plain, solid colour.

Covering Different Book Types

Not every book covers the same way.

Our guide to stapled, spiral and wiro-bound notebook binding explains how each binding type behaves under daily use, which is worth checking before you decide how to cover a particular book.

Common Mistakes When Covering Books

• Peeling the entire backing off at once: This is the most common cause of bubbles and creases.
• Skipping the corner notch: Without a small triangle cut at each corner, the film bunches instead of folding flat.
• Covering a dusty or damp book. Trapped dust or moisture creates a permanent bump under the film.
• Choosing contact that is too thin for daily handling: Light film tears more easily over a full school year.
• Leaving an uneven label underneath the contact: Any label placed under the film should be completely flat and secure before covering. 
• Rushing a slip-on cover onto the wrong size: A poor fit slides and looks untidy within weeks.

Frequently Asked Questions

How do I cover school books without bubbles?

Work slowly, peeling only a small section of the contact paper's backing at a time rather than all at once. Press from the centre outward, smoothing air toward the edges as you go, and start at the spine to keep everything aligned.

Is contact or slip-on better for school books?

Contact gives a more permanent, protective finish but takes more practice. Slip-on covers are faster and reusable, but need correct sizing to sit properly. Both are reasonable choices unless your school specifies one.

How do I fix a bubble that has already set?

For a small stubborn bubble, a very small pin prick can let trapped air escape. Keep the puncture tiny and press gently from the centre outward before smoothing the area flat. 

What thickness of contact paper should I use for school books?

A heavier film generally holds up better than the lightest option for a book that will be handled daily for a full school year, though exact recommendations vary between brands.

Can I cover a spiral or wiro-bound notebook the same way as a stapled one?

Mostly, yes, though take extra care of trimming contact paper close to the coil or wire spine rather than wrapping directly over it, since the spine flexes during use.

Getting a Clean, Lasting Cover on Every Book

Contact paper gives the most durable, personalised finish once you have the peel-and-press technique down. Slip-on covers trade some of that permanence for speed and reusability. Either way, most bubble problems come down to rushing the process rather than the materials themselves.

Work slowly, start at the spine, and check for bubbles as you go rather than at the end. For the full buying picture on notebooks and paper, see our notebooks and paper for school guide. Ready to shop notebooks to cover? Browse our Notebooks & Paper collection.
