The product is a laminate of polyetylene film with fibers in the
middle to provide substantial extra strenght. The propoertities of
light emission, resistence to UV, IR and shade are known, the sizes
are suitable for green house application, i.e. 30 feet by over 300
feet. Question who are the companies manufacturing this or similar
materials in U.S., Asia, Europe, and New Zealand/

Hi there,

If the fiber-reinforced polyethylene you are searching for is similar
to that shown here ( http://www.tylersdisplay.com/visqueen.html ),
then the manufacturer is Visqueen, part of the British Polythene
Industries group.

Visqueen Agri ( http://www.visqueenagri.com/ ) 
Visqueen Building ( http://www.visqueenbuilding.co.uk/ )
British Polythene Industries ( http://www.bpipoly.com/ ) under "BPI
Industrial"

The Plastics Distributor & Fabricator Buyer's Guide (
http://www.plasticsmag.com/buyguide.asp ) cross-referenced with
searches on other brand names (Solar Max, Poly Max, ScrimWeave) found
on greenhouse supply retailers pointed me to two more manufacturers:

ThorTarp ( http://www.thortarp.com/applications/clear_grnhse.htm ) and
GreenTek's Solar Max ( http://www.green-tek.com/FRset_GrPr.html )

Raven Industries' Dura*Skrim 10HUV (
http://www.ravenind.com/eng_films/specs_dura_10huv_framed.html ) is
another reinforced UV-stablized polyethylene.

Other major plastics companies like Dow (
http://www.dow.com/polyethylene/na/app/agri.htm ),
AT Plastics ( http://www.atplastics.com/films/g_list.htm ), 
DuPont ( http://www.dupont.com/polyester/resins/products/biomax/ ) and
ICI do not list anything about reinforced polyethylene agricultural
film.

Search Strategy:

I started with the terms "polyethylene greenhouse" and "reinforced
polyethylene film". Then I searched the brand names that I found in
looking for the manufacturer:
"Solar Max"
"Poly Max"
"ScrimWeave"
"Visqueen"
Then I looked through industry sites like Plastics Distributors &
Fabricators Magazine and ran the same terms through Usenet.

I hope this helps you.  Please feel free to ask for clarification if
necessary.

Hi lingcod,

Here's what I was able to locate so far:

Plastic greenhouse film, South Africa:

http://www.strangeways.co.za/products_page.htm

not among the locations you specified, but I
threw it in, just in case...

Plastic greenhouse film, USA:

"Armin Plastics Corp. 18901 East Railroad Street City of Industry, CA
91748 Tel: 800-654-8119 URL: ( http://www.armin.com ) (supplies a full
range of single layer plastic, UV protected greenhouse coverings -
suitable for warmer climates."
http://www.joelskousen.com/Secure/recommended.html

Neither site specifies whether the plastic in the film is
polyethylene.

Search, via Google:

"plastic greenhouse film"
