Greenhouse Plastic 5.5m x 75m – 200 Micron Covering Film for Greenhouses & Tunnels

Greenhouse Plastic 5.5m x 75m: 200 Micron Covering Film

This greenhouse plastic is a heavy-duty covering film for greenhouses, poly tunnels and grow houses. The roll is 5.5 metres wide and 75 metres long at 200 microns thick, which gives a large, continuous sheet, over 400 square metres, suited to covering full structures or running long tunnel houses without lots of joins.

The 200 micron gauge is the important part. It's a genuinely heavy film rather than a light drop-sheet, so it holds up to wind, handling and being stretched over a frame far better than thin builder's plastic. That thickness is what lets a greenhouse cover last through the seasons while still passing light through to the plants inside.

Key Details

• Heavy-duty 200 micron thickness

• 5.5m wide x 75m long, a large single roll for full structures

• Translucent film that lets light through while enclosing the space

• Suited to greenhouses, poly tunnels, hoop houses and grow houses

• Cuts to length for the structure you're covering

What It's Used For

A greenhouse film like this creates a warm, sheltered growing environment by trapping heat and holding humidity, while still letting light reach the plants. That's useful for extending the growing season, raising seedlings, protecting tender plants from cold and wind, and keeping crops going through cooler months. At 5.5m x 75m it's a commercial-scale roll, so it suits larger home growers, market gardens and anyone covering multiple or long structures rather than a single small frame.

Fitting It

Measure your structure and allow extra film on all sides so you can pull the cover taut and fix it down, since a tight cover flaps less and lasts longer. Secure it to the frame with batten tape, clips or timber battens rather than just staples through bare film, which tear out under wind load. Avoid stretching it over sharp edges or rough timber, and smooth ridges or cap them so the film isn't cut or worn at contact points. Fitting the cover on a warmer day helps, as the film is more flexible and pulls tighter as it cools.

Frequently Asked Questions

What size is this greenhouse plastic?
It's 5.5 metres wide and 75 metres long, at 200 microns thick, which is a large commercial-size roll.

How thick is 200 microns?
It's a heavy-duty gauge, much stronger than standard thin plastic sheeting, which is what allows it to stand up to wind and season-long use as a greenhouse cover.

What can I use it for?
Covering greenhouses, poly tunnels, hoop houses and grow houses to create a warmer, sheltered growing space and extend the growing season.

Does it let light through?
Yes. It's a translucent film that passes light to the plants inside while enclosing the space to hold heat and humidity.

How do I secure it to my frame?
Use batten tape, clips or timber battens and pull the film taut, allowing extra on the edges. Avoid sharp edges and rough timber that can cut or wear the film.

Where can I buy greenhouse plastic in Australia?
It's available from BPG Supplies (Bonnyrigg Produce & Garden Supplies), with local pickup in Bonnyrigg NSW and delivery across Australia.
