What Is Thick Plastic Sheeting Called? The Industrial Naming Guide
In our daily production of industrial plastic components, we classify anything over 0.25 inches (6mm) as plastic plate or plastic stock board—these thick plastic sheeting variants serve critical structural roles from machine bases to load-bearing partitions, with material engineers using precise terminology based on both thickness and polymer composition to ensure proper material selection for heavy-duty applications where standard plastic sheets would warp or fracture under stress.
Snippet paragraph: Thick plastic sheeting is technically designated as plastic plate (0.25"-1") or plastic slab (>1") in industrial contexts, with specific names like polycarbonate armor plate or UHMWPE bearing board indicating material properties—these structural-grade plastic sheets undergo different manufacturing processes than thin sheeting to achieve enhanced strength and dimensional stability.
The terminology reveals important technical distinctions—let's examine them.
How Is Thick Plastic Sheeting Classified by Thickness?
Snippet paragraph: Industry classification:
Plastic Thickness Categories
| Term | Thickness Range | Prime Applications |
|---|---|---|
| Film | <0.010" (0.25mm) | Protective wrapping |
| Sheeting | 0.010-0.249" (0.25-6mm) | Machine guards |
| Plate | 0.250-1.000" (6-25mm) | Structural components |
| Slab | >1.000" (>25mm) | Machine bases |
Production Note: We machine plates up to 3" thick.
