This invention relates to bags and pouches made from films for packaging of flowable materials, in particular liquids that are made from blends of polyethylene and polypropylene useful to in addition to possessing good flex crack resistance, these films can withstand steam sterilization and/or aseptic packaging conditions as they have Hot Tack Initiation Temperatures in the range of from about 100&#xb0; C. to about 140&#xb0; C. and Hot Tack Strengths of not more than 5 N/inch in the temperature range from 100&#xb0; C. to 150&#xb0; C.

Resin blend of ethylene alpha olefin interpolymer and heterogeneous interpolymer for liquid packaging films

This invention relates to blends of polyethylene and polypropylene useful to make films for packaging of flowable materials, in particular liquids. In addition to possessing good flex crack resistance, these films can withstand steam sterilization and/or aseptic packaging conditions as they have Hot Tack Initiation Temperatures in the range of from about 100&#xb0; C. to about 140&#xb0; C. and Hot Tack Strengths of not more than 5 N/inch in the temperature range from 100&#xb0; C. to 150&#xb0; C.

Pouch making process including use of liquid packaging films of polyethylene and polypropylene blends

A method and composition is disclosed for making conductive flow field separator plates having reduced resistivity, lower weight and lower cost. The plates are made by blending from about 0.5 wt % to about 40 wt %, preferably from about 1 wt % to about 30 wt %, most preferably from about 5 wt % to about 20 wt %, of the liquid crystal polymer; from about 0.5 wt % to about 40 wt %, preferably from about 1 wt % to about 30 wt %, most preferably from about 5 wt % to about 20 wt % of the poly(styrene-co-maleic anhydride); and from about 20 wt % to about 99 wt %, preferably from about 60 wt % to about 98 wt %, most preferably from about 70 wt % to about 90 wt % of the conductive filler. The blend is then moulded to form the conductive flow field separator plates.

Composition and method for making fuel cell collector plates with improved properties

A method for making a shaped article or a shaped article having a volume resistivity of less than 10ohm-cm with a desired combination of properties and processibility in an injection moldable composition. In particular the shaped articles formed include injection molded bipolar plates as current collectors in fuel cell applications.

Injection moldable conductive aromatic thermoplastic liquid crystalline polymeric compositions

The present invention provides a process for decreasing the resistivity of a non-machined conductive flow field plate for use in a fuel cell. The process includes the step of annealing the conductive flow field plate by heating the conductive flow field plate to a temperature between 25&#xb0; C. (room temperature) and a temperature slightly lower than the material softening temperature of the material composition of the conductive flow field plate; maintaining the conductive flow field plate at that temperature for an effective period of time; and, cooling the conductive flow field plate to room temperature.
