Foam Board & High Impact Sheets: A Complete Guide to Just Foam Board, High Impact Bluish White, and Rigid PVC Clear Sheets

Three specialized substrates for lightweight displays, impact-resistant panels, and flexible rigid applications — here's how they differ and when to use each one.

Quick Summary
  • Three distinct substrates: Foam Board (ultra-light indoor displays), High Impact Bluish White (durable panels), and Rigid PVC Clear (thin transparent overlays)
  • Just Foam Board is the lightest substrate in the range — 5mm, 4×8ft, cuts with a utility knife
  • High Impact Sheet offers greater physical impact resistance than expanded PVC foam for demanding environments
  • Rigid PVC Clear (0.5mm–1.0mm) is used for document holders, POP display windows, and protective print overlays

Just Foam Board — Lightweight Display Substrate

Just Foam Board is a polystyrene foam core sandwiched between two thin paper or clay-coated facing sheets. It is the lightest rigid display substrate available — easy to cut with a knife, simple to print on, and widely used for temporary and short-term signage, presentation boards, and indoor displays.

SpecificationValue
Thickness5mm
Sheet Size4×8ft (1220×2440mm)
CorePolystyrene foam
FacingWhite clay-coated paper
WeightUltra-lightweight (~0.3 kg/m²)
CuttingKnife/cutter cuttable, laser cuttable
UseIndoor only (not weatherproof)

Best for: Real estate display boards, election campaign signage, indoor POP displays, presentation panels, and trade show display boards.


High Impact Sheet Bluish White — Durable Rigid PVC

High Impact Sheet is a rigid, high-impact-resistant plastic sheet in a distinctive bluish-white color. It is denser and more impact-resistant than standard Sintra Board, making it suitable for applications where toughness is required — such as machine guards, industrial panels, and heavy-duty display fixtures.

Note: The bluish tint is a characteristic of this grade's polymer formulation and provides a neutral appearance suitable for industrial and structural applications.

Best for: Industrial machine covers, protective panels, heavy-duty fixture components, and structural display elements that need to withstand physical stress.


Rigid PVC Clear — Thin Transparent Sheet

Rigid PVC Clear is a transparent, hard PVC sheet in thin gauges (0.5mm and 1.0mm). It is stiffer than flexible PVC film but thinner and more flexible than acrylic sheet — occupying a useful middle ground for packaging, menu covers, name tag inserts, and light-duty transparent panels.

SpecificationValue
Thickness Options0.5mm, 1.0mm
ColorClear (transparent)
MaterialRigid PVC (uPVC)
FlexibilitySemi-rigid (bends without cracking at thin gauges)
ApplicationsPackaging windows, menu card covers, badge inserts, protective overlays

Best for: Packaging with transparent windows, book covers, menu laminate inserts, ID badge overlays, and small transparent protective panels.
