A cosmetics brand replaced 1,400 acrylic counter stands after a quarter of them arrived at stores with corner cracks. The replacement run was PETG. Six months later, none had cracked, and the brand has not gone back. The interesting part is what they did not change: the design, the dimensions and the print.
What the rollout actually showed
- Breakage in transit fell from 23% to under 2% — PETG bends where acrylic chips
- Edge polishing time dropped, because a routed PETG edge takes a flame pass rather than three grits
- Chemical cracking near the print cleaning station disappeared, which is the failure nobody attributes to material choice
- Scratch visibility rose, because PETG is softer than cast acrylic — this is the trade the brand accepted
The 3 mm versus 4 mm decision
A 3 mm PETG stand up to 300 mm tall with a 120 mm shelf is adequate: the material flexes and returns. Above 400 mm, or with a loaded shelf over 2 kg, 3 mm creeps and the stand leans within a season. The fix is not 5 mm — it is 4 mm plus a folded foot, because the foot carries the moment and the extra millimetre only adds stiffness where the failure is not happening.
Where acrylic still wins
Cast acrylic keeps a sharper edge, holds a deeper polish and does not scratch as readily. For a fixed counter unit that is cleaned with a dry cloth and never shipped, cast acrylic in 4 mm is still the better surface. The choice is really a logistics question: how many hands and how many kilometres will the fixture see before it is scrapped?
On a flat-packed programme, specify PETG at 4 mm, route rather than laser-cut the outer profile to avoid the recast edge, and flame-polish. If the fixture is a shelf-edge or signage piece rather than a stand, retail signage material selection and display stand fabrication cover those variants.
Cost is not the deciding factor in most switches, but it is close. PETG sheet at 4 mm typically runs below cast acrylic at the same thickness, and the finishing saving on the edge is real: a routed PETG edge takes one flame pass where acrylic takes three grits and a polish. On 1,400 units that is several hundred hours of bench time.
The design change that matters most is the corner radius. PETG survives a drop because it distributes the impact, and a sharp internal corner concentrates it. Reworking a 90° corner into a 3 mm radius, and moving the fixing 10 mm inboard from the edge, removed most of the remaining breakage in the second half of that rollout.
Shipping format decides the second half of the cost. Flat-packed units need a dieline that protects the corners, and a PETG fixture shipped in a printed carton with a corner board survives a parcel network that would destroy a bare acrylic unit. Ask for a transit test on the first fifty units rather than on the whole rollout.

Brands tend to ask the same three things before switching material.
Frequently Asked Questions
Q: Is PETG better than acrylic for POS displays?
A: For fixtures that are shipped flat-packed or handled repeatedly, yes: PETG bends rather than chips, so transit breakage drops sharply. For fixed units needing a hard, polished surface, cast acrylic still wins.
Q: What thickness PETG for a counter display stand?
A: 3 mm up to about 300 mm tall with a light shelf. Above 400 mm or with more than 2 kg on the shelf, use 4 mm plus a folded foot rather than going thicker.
Q: Can PETG be laser cut for displays?
A: It can, but the recast edge shows and cracks later. Routing the profile and flame-polishing the edge gives a cleaner, stronger result.
