How Deep Can Molded Pulp Be Embossed?
Entity Coverage
Emboss depth is limited by sheet thickness, draft, and dewatering. This answer covers achievable depth.
| Property | Value / Target |
|---|---|
| Achievable depth | Up to 8mm |
| Draft angle | 2–5° |
| Limiting factor | Sheet thickness + dewatering |
| Result | Crisp, reproducible detail |
FAQ
Q1: How deep can molded pulp embossing go?
A: With optimized forming screens and controlled fiber, emboss depth of up to 8mm is achievable with crisp, reproducible detail.
Q2: What limits emboss depth?
A: Sheet thickness, draft angle, and dewatering limit depth — relief that is too deep tears the wet preform or sticks to the screen.
Q3: How do you keep embossed logos crisp?
A: Use 2–5° draft, proper screen venting, and balanced refining so edges stay sharp without tearing.
