The Ideal Baseboard or Barrier Material for Your Epoxy Resin Project

Polypropylene plastic sheet is ideal for use as a non-stick baseboard or barriers for your GlassCast epoxy resin projects. It has a smooth finish and is easy to cut and bond.

Polypropylene has a smooth finish, is easy to cut and bond and has enough stiffness to help construct sturdy barriers or produce a smooth base. Best of all, epoxy resin does not stick to polypropylene meaning the sheet requires no release agent and can be re-used again and again.

Our polypropylene sheet is 3mm thick and a natural translucent colour. The sheet is available in a range of sizes, please choose the size you require from the drop-down list at the top of the page.

Polypropylene Sheet Recommended Uses

When working with GlassCast epoxy resins, there are many situations where you need to construct barriers or a box to contain the resin whilst it cures. This can be for anything from small-scale jewellery projects through to larger wood turning, or furniture making projects and including of course large pieces like river tables or resin plank tables. In all these situations, it's really helpful to have polypropylene plastic sheet as the perfect smooth, non-stick material to use for the baseboard and sides.

  • Baseboard and sidewalls for a river table
  • Container for layered 3D resin art
  • Custom mould shape for jewellery pieces
  • Fitted 'resin bath' container for wood stabilisation
  • Custom mould shapes for pen-blanks

Polypropylene Sheet Advantages

  • Smooth and shiny finish
  • Completely non-stick to epoxy resin
  • Can be re-used again and again
  • Easy to cut and shape
  • Can be heated/bent if required

How to Use

Using polypropylene sheet as a baseboard, barriers or container for your GlassCast resin project could not be easier. Simply cut the sheet into the sizes you need using a hand saw. Where necessary, assemble the parts using a hot-melt glue-gun or some Resin Barrier/Release Tape, both of which allow the container to be dismantled once the resin has cured.


Please note: Polypropylene sheet is manufactured as an industrial material, it is also quite soft and does mark easily. It is not intended to be cosmetically perfect and some light scratches from manufacture or handling should be expected.

If you intend to use the sheet to produce the final finish on your part then some light finishing work will be required.

Questions Asked About Polypropylene Sheet

This polypropylene sheet is semi-translucent. It is a natural white colour which does allow some light to pass through.

Unfortunately not, it's not possible to polish low density thermoplastics like polypropylene; or at least not possible with any process that could be done at home. Really your only solution would be to polish the scratches out of the cured resin component instead.

Most glues will not bond well to polypropylene. However, hot melt glues work very well for the temporary bonding of polypropylene sheeting for use as mould boxes and mould flanges.

Polypropylene can be cut and machined using conventional wood working tools and methods, if machining, care must be taken to avoid heat building up as the plastic can melt slightly and leave a poor edge, sharp blades and reasonably fast feed rates normally eliminate this problem. 

Any burr left on the edge after cutting can be quickly cleaned-up using a sharp blade dragged sideways along the edge.  

This would depend on the size of the table. For most table sizes a thin strip of polypropylene could easily be bent round to form the outer barrier but but if the table was particularly small then you might need to consider something thinner.  Alternatively, you could make a barrier using any flexible material you like and then apply Resin Release Tape to this material to make it non-stick as the GlassCast won't stick to the release tape.

It would depend on the size of the table. Given enough radius the polypropylene sheet would bend around it fine but if it's a small piece with a tight radius then you might want to look for a thinner sheet. Alternatively, make a barrier using a more flexible material like the Resin Release Tape as the GlassCast resin will not stick to it.
