Abstract
Abstract The invention relates to a method for protecting plants during transportation by packaging plant (2) and its pot (1) in a bag (3) which at least partly consists of microporous material (6) having preferably an air-permeability of 0.1-300 mm 3 air per second per Pascal per m 2 of the film material with pore diameters of less than 0.5 μm due to which the bag (3) is self-inflatable, exchange of gases still takes place and the climate within the bag (3) is kept constant.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
112 words
A method for protecting potted plants during transport which comprises the steps of (a) enclosing the potted plant including soil with moisture and nutrients for said plant in a flexible and sealable package comprising a microporous film portion and a second portion of a transparent substantially impervious plastic film, the microporous film having an air-permeability of 0.1 to 300 mm 3 air per second per Pascal per m 2 of the film with pore diameters smaller than 0.5 μm, and the package being self-inflating within a short time after sealing due to evaporation of the moisture supplied by the potted plant, (b) sealing the package, and (c) permitting the package to self-inflate.
Claim 2
Independent Claim
112 words
A method for protecting potted plants during transport which comprises the steps of (a) enclosing the potted plant including soil with moisture and nutrients for said plant in a flexible and sealable package comprising a microporous film portion and a second portion of a transparent substantially impervious plastic film, the microporous film having an air-permeability of 0.1 to 300 mm 3 air per second per Pascal per m 2 of the film with pore diameters smaller than 0.5 μm, and the package being self-inflating within a short time after sealing due to evaporation of the moisture supplied by the potted plant, (b) sealing the package, and (c) permitting the package to self-inflate.
Claim 3
Dependent Claim
99 words
An article of manufacture comprising a potted plant including soil with moisture and nutrients for said plant and a package surrounding said potted plant, the package comprising a sealable flexible package, one portion of which is a microporous film having an air-permeability of 0.1 to 300 mm 3 air per second per Pascal per m 2 of the film with pore diameters smaller than 0.5 μm, and another portion of which is a transparent substantially impervious plastic film, the package being self-inflating within a short time after sealing due to evaporation of the moisture supplied by the potted plant.
Claim 4
Dependent Claim
99 words
An article of manufacture comprising a potted plant including soil with moisture and nutrients for said plant and a package surrounding said potted plant, the package comprising a sealable flexible package, one portion of which is a microporous film having an air-permeability of 0.1 to 300 mm 3 air per second per Pascal per m 2 of the film with pore diameters smaller than 0.5 μm, and another portion of which is a transparent substantially impervious plastic film, the package being self-inflating within a short time after sealing due to evaporation of the moisture supplied by the potted plant.
Claim 5
Dependent Claim
32 words
The article of claim 2, wherein the microporous film portion of the package forms the rear side of the package and the balance of the package is transparent substantially impervious plastic film.
