Regpre
Regpre Acetate Cake Collar Roll, 3 in x 32.8 ft, 125 Micron
$13.99
Cake Collar 3 Inch
A 3 inch (about 8 cm) cake collar is the standard height for lining a cake ring or wrapping a chilled layer cake, mousse or cheesecake so the sides set straight. Shoppers here mostly choose the Regpre 3 inch acetate roll: one continuous 32.8 ft (10 m) strip of clear, 125 micron food-grade PET that you cut to the length of each cake. If some of your cakes stand taller than 3 in, the 3 in and 4 in collar set gives you a 32.8 ft roll of each width. Both are for cold-set work, not the oven.

Regpre Acetate Cake Collars Set, 3 in + 4 in Rolls, 32.8 ft Each
$15.99
Two 32.8 ft rolls, one 3 in and one 4 in wide, both 125 micron PET, for bakers who also make taller cakes.
What to look for
- Measure the finished height first. A 3 in collar suits a single cake ring or a short layered cake; for taller entremets or stacked mousse layers, go 4 in, or stand a second strip above the first.
- Cut each strip to the cake's circumference plus about 1 in of overlap, then tape the overlap on the outside so the seam stays smooth against the cake.
- Fit the collar inside a cake ring or springform for heavy fillings. The ring takes the outward pressure while the acetate gives the clean, glossy side.
- Chill or freeze the dessert fully before you peel the collar. Pull it away in one slow, steady motion along the side rather than lifting it straight up.
- Keep acetate out of the oven. The listing states it is not heat-resistant, so use it for chilled cakes, mousse, cheesecake and chocolate work.
- Store the roll flat and dry so the strip does not pick up kinks; a crease will print onto a smooth mousse side.
How long to cut a cake collar for each cake size
The collar length is the circumference of the ring or cake: diameter x 3.14 (pi). Add about 1 in of overlap to tape the seam. The table rounds to the nearest inch and is an estimate; measure your own ring, since ring sizes vary slightly. A 32.8 ft roll is about 393 in long.
| Cake or ring diameter | Circumference (approx.) | Cut length with 1 in overlap | Collars per 32.8 ft roll (approx.) |
|---|---|---|---|
| 4 in (10 cm) | 12.6 in | 14 in | 28 |
| 6 in (15 cm) | 18.8 in | 20 in | 19 |
| 7 in (18 cm) | 22.0 in | 23 in | 17 |
| 8 in (20 cm) | 25.1 in | 26 in | 15 |
| 9 in (23 cm) | 28.3 in | 29 in | 13 |
| 10 in (25 cm) | 31.4 in | 32 in | 12 |
| 12 in (30 cm) | 37.7 in | 39 in | 10 |
3 inch or 4 inch: which collar width?
Choose the width that is at least as tall as the finished cake, or a little taller, so the top edge stays clean while you fill. A 3 in collar matches most single-ring desserts and short layer cakes. A 4 in collar gives room for tall layer cakes, mousse cakes with several fillings and anything you plan to top with a glaze that should set inside the collar. If you bake both styles, the two-roll set saves buying twice.
Frequently asked questions
How wide is a 3 inch cake collar in centimeters?
3 in is about 7.6 cm; the Regpre roll is listed as 3 in (8 cm) wide. It comes as one continuous 32.8 ft (10 m) roll, so you cut each collar to length.
How thick is this acetate, and is it food grade?
Both rolls are 125 micron PET (polyethylene terephthalate) acetate, listed as food grade for direct contact with desserts. That thickness is flexible enough to curve around a round or shaped cake and firm enough to hold a filled layer.
Can I bake a cake in an acetate collar?
No. The listing states the acetate is not heat-resistant and must not go in the oven. Bake first, then use the collar to assemble, fill and chill the cake, or for mousse, cheesecake and chocolate work.
Can I reuse a cake collar?
Collars are usually treated as single-use once they have touched cream or mousse, since they can crease when peeled. A long roll is the practical answer: one 32.8 ft roll makes about 15 collars for 8 in cakes.
Should I get the 3 in roll or the 3 in and 4 in set?
If your cakes finish at 3 in tall or less, the single 3 in roll is enough. If you also make taller layer or mousse cakes, the set gives you a 32.8 ft roll of each width, 65.6 ft in total.
