Regpre Acetate Cake Collars Set, 3 in + 4 in Rolls, 32.8 ft Each

Why get both 3 in and 4 in acetate cake collars?

This set gives you two rolls of clear acetate cake collar, one 3 in wide and one 4 in wide, each 32.8 ft (10 m) long, for 65.6 ft in total. Most chilled desserts land at one of those two heights, so you can match the collar to each cake instead of trimming a wide roll every time. Both rolls are food-grade PET, 125 microns thick.

Which roll to reach for

Stacking the two widths for an extra-tall cake

For a cake taller than 4 in, line the ring with a 4 in strip and build the first layers. Then slide a 3 in strip between the ring and the first collar, overlapping it by about an inch, so the wall rises with the cake. With that overlap the combined wall stands close to 6 in. Tape both seams on the outside face and chill as usual.

If you would rather have one seamless wall, a single 5 in acetate roll covers cakes up to about 4.5 in.

How far does the set go?

Strip length is the ring's diameter times 3.14, plus 1 to 2 in of overlap. Each roll gives about 19 strips for 6 in rings or about 14 for 8 in rings, so the pair covers roughly 38 six-inch or 28 eight-inch desserts, split between the two heights. When one width runs out first, a single 3 in roll or 4 in roll restocks it.

What 125 microns means

125 microns is 0.125 mm, or about 4.9 mil. That is a fairly firm film for mousse and layer cakes: it curves around a ring yet holds a straight wall while the dessert sets in the fridge. If you have used 4.75 mil acetate before, this is very close. Thinner films wrap tiny desserts more easily but can buckle under a heavy filling.

Cutting, release and chocolate work

Cut strips with sharp scissors against a ruler. Once the dessert is fully chilled, the smooth face peels away cleanly without tearing a mousse wall or smudging decorations. The same surface leaves tempered chocolate glossy, so spare strips are handy for chocolate bands and shards.

Use the rolls for chilled and cold-set work, not in the oven. Store them in their packaging or a flat box at room temperature, away from heat and sunlight, so they stay flat and clear.
