Semi-rigid polyethylene packaging foam
What Is Ethafoam STPE200?
Quick answer
Ethafoam STPE200 is a semi-rigid, non-cross-linked expanded polyethylene foam designed for cushioning, gap filling and impact absorption. It is more structured than soft flexible packaging foam, while still providing controlled compression around suitable products and components.
Ethafoam, Stratocell or Jiffy foam?
These names are often used in searches for semi-rigid polyethylene packaging materials, but a trade name alone does not prove that two products have the same specification. All Foam supplies STPE200, so compare the actual grade, density, dimensions and intended application rather than relying on a name alone. Read our Ethafoam, Stratocell and Jiffy foam guide for a fuller explanation.

Why choose STPE200?
Why Ethafoam Works for Protective Packaging
Ethafoam is useful when the packaging needs a supportive semi-rigid layer rather than a very soft cushion. Its value comes from matching the material to the load, case design and journey rather than simply choosing the thickest sheet available.
Semi-rigid support
STPE200 keeps a more defined shape than flexible polyurethane packaging foam. That makes it useful for separators, pads, barriers and protective layers that need to hold their position around an item.
Controlled cushioning
The material is designed for cushioning and impact absorption. It can compress under load while providing a more structured support layer for suitable medium and heavy items in transit.
Low water absorption
STPE200 has water absorption of 1.19% by volume after 24 hours. That can be useful where the packaging may encounter moisture, although the suitability of the complete pack still depends on the environment.
Wide working temperature range
The stated working temperature range is -30°C to +80°C. Temperature is only one design factor, so adhesives, surrounding materials and the complete application must also suit the environment.
Useful for gap filling
As well as cushioning products, Ethafoam can be used to fill controlled spaces between structural members or protective barriers where a stable semi-rigid foam layer is appropriate.
Multiple supply formats
STPE200 can be supplied as sheets and can also be considered for block, profile and bespoke cut-to-size requirements. Contact All Foam where the job does not fit the standard online sheet options.
Packaging and industrial applications
What Is Ethafoam Used For?
The strongest applications are those that need semi-rigid cushioning, controlled spacing or a protective barrier. Start with the item and its journey, then choose the thickness and layout around the load.
Transit pads and separators
Use Ethafoam as a structured pad or separation layer between products, components or hard surfaces where direct contact needs to be controlled during handling and transport.
Crates and transport cases
Semi-rigid foam can line suitable crates and cases or form supporting blocks around equipment. Plan enough clearance for cushioning without forcing pressure onto delicate controls, corners or connectors.
Medium and heavy items
STPE200 is used for cushioning medium and heavy items in transit. The contact area matters as much as total weight because narrow feet or corners concentrate the load into a smaller area of foam.
Gap filling and protective barriers
The material can fill planned gaps between structural members and form protective barriers where a supportive polyethylene foam is required between the product and a harder surrounding structure.
Shock-absorbing industrial layers
Ethafoam can form a cushioning layer within suitable industrial protection systems. For machinery, racks, posts or other engineered uses, confirm the dimensions, loading and required performance before ordering.
Thermal and vibration insulation
STPE200 can be used as an insulating or vibration-control layer in suitable industrial assemblies. It should be selected as part of the complete assembly rather than treated as a universal insulation product.
Packaging electronics?
Ethafoam provides physical cushioning, but do not assume that ordinary STPE200 provides a required electrostatic discharge specification. Where electronics need anti-static protection, compare the Pink Anti-Static Packaging Foam and check the exact ESD requirement.
Compare before ordering
Ethafoam vs Other Packaging Foam Types
Ethafoam is one option within a wider protective foam range. Compare how the material needs to behave before choosing by colour, price or thickness.
| Foam type | Structure and feel | Best suited to | Key check |
|---|---|---|---|
| Ethafoam STPE200 | Semi-rigid non-cross-linked expanded polyethylene | Transit pads, separators, gap filling, crates and structured cushioning | Not fire retardant; choose thickness from the complete load and pack |
| Flat Packaging Foam | Flexible polyurethane cushioning foam | Boxes, case bases, protective layers and general flexible cushioning | Not fire retardant and not intended for upholstery |
| Pink Anti-Static Foam | Flexible anti-static polyurethane | Relevant electronic components and static-sensitive products | Confirm the exact ESD requirement |
| Closed Cell AFP30 / AFP45 | Cross-linked polyethylene sheets with a more rigid structure | Reusable liners, inserts, seals and firmer protective applications | Compare AFP30 and AFP45 by rigidity, density and load requirement |
| Plastazote LD33 | Fine-cell cross-linked polyethylene with colour choice | Presentation inserts, tool trays, displays and detailed fabrication | Choose technical suitability before appearance or colour |
Ethafoam has its own product role. All Foam keeps STPE200 within the semi-rigid packaging range rather than grouping it with the dedicated Closed Cell Foam Sheets range of AFP30, AFP45, Plastazote and EPDM.
Practical buying guidance
How to Choose Ethafoam for a Packaging Project
There is no single STPE200 thickness for every product. A good design considers the item, contact area, fragile features, available case depth and expected handling before the foam is ordered.
1. Measure the item accurately
Measure the widest, longest and highest points, including handles, feet, connectors and controls. Identify which surfaces can safely carry the load and which areas need clearance.
2. Check weight and contact area
A broad flat item spreads its load differently from an item resting on narrow feet. Concentrated contact points can compress foam more heavily even when the total item weight is the same.
3. Measure the usable case or box
Use internal dimensions rather than the outside of the case. Allow for hinges, catches, ribs, wheel housings, rounded corners and any part of the container that reduces the space available for foam.
4. Plan every protective layer
Divide the usable space between the base, sides, ends and lid. The foam needs room to cushion the item without leaving it loose or forcing constant pressure onto vulnerable parts.
5. Consider the journey and reuse
A one-way shipping carton has different priorities from a reusable service case or industrial transit pack. Consider repeated handling, stacking, vibration, storage and how often the item will be removed.
6. Test the finished pack
Check that the item cannot move freely, bottom out against a hard surface or become trapped under excessive pressure. Commercial packaging should use an appropriate documented test process where required.
