Black Plastic Film — Buying Guide
Black plastic film (also known as black poly film, black polyethylene sheeting, or black plastic mulch) is one of the most versatile and cost-effective materials used in landscaping, horticulture, and construction across Australia. Its opacity blocks sunlight completely, suppressing weed growth, retaining soil moisture, and raising soil temperature — making it a valuable tool for gardeners, market growers, and landscape professionals alike.
Common Uses for Black Plastic Film
- Weed suppression: Laid under mulch, gravel, or aggregate to prevent weed growth without herbicide use. Widely used in garden beds, driveways, pathways, and landscaped areas on the Sunshine Coast and Brisbane
- Soil solarisation: Placed directly on the soil surface for 4–8 weeks during summer to use solar heat to kill weed seeds, soil-borne diseases, and nematodes — a natural, chemical-free soil treatment
- Vegetable garden mulch: Laid over prepared soil before planting through cut holes, black film suppresses weeds, conserves moisture, and raises soil temperature for improved germination and growth
- Moisture barrier: Used under concrete slabs, footpaths, and paved areas as a moisture vapour barrier to prevent ground moisture migrating up through the substrate
- Civil and construction: Temporary ground cover, protection film for concrete work, waterproofing layer in civil earthworks
- Pond liner base layer: Used as a protective underlayer beneath EPDM or butyl rubber pond liners
Choosing the Right Thickness
- 50–75 micron: Light-duty temporary film — suitable for short-term weed suppression under mulch, soil solarisation, and temporary construction cover
- 100 micron: Standard-duty film — good for landscape weed suppression, vegetable garden mulch, and most garden bed applications
- 200 micron (200μm): Heavy-duty film — recommended for long-term under-aggregate installation, concrete sub-floor moisture barriers, and civil applications where extended service life is required
Frequently Asked Questions
How long does black plastic film last underground or under mulch?
UV-stabilised black plastic film used under mulch or aggregate typically lasts 5–10 years. Film exposed directly to sunlight will degrade more quickly — use UV-stabilised product for any above-ground applications or choose geofabric for long-term exposed applications.
Can I use black plastic film in a vegetable garden?
Yes — black plastic film is widely used in market gardens and home vegetable plots to suppress weeds and retain moisture. Plant through cut holes or slits in the film. Be aware that film will prevent rainfall from reaching the soil, so drip irrigation underneath the film is recommended for best results.

Yes — we offer Australia-wide delivery including to Brisbane, the Sunshine Coast, and all of South East Queensland.
