[papercreters] Re: New one in Peru -South America-

Dear NT,
To my knowledge, Tetrapack cartons are usually lined with plastic or aluminum foil.
See the following extract from Wikipedia :
https://secure.wikimedia.org/wikipedia/en/wiki/Tetra_Pak

Tetra Pak's first product was a paper carton used for storing and transporting milk. The first product was a package in the shape of a triangular pyramid (or tetrahedron), called the Tetra Classic. Ruben Rausing and his team had been working on the Tetra Classic design since 1944, and by 1952 had perfected techniques for making his cartons fully airtight, using a system of plastic coated paperboard.
The lining will cause immense grief as cement will not stick to it and the output will have poor strength.

That said I have not practically used Tetrapack in papercrete.
Regards
Ashok

I´ve read almost everything about it and now is the time to make it real. In a short time I´ll move to the town I choose for this application and want to share every step with you all.
