Abstract
Official abstract text for this publication.
Composition and method for making a flexible packaging film having highly loaded with at least one inorganic filler. A blown HDPE film comprising at least 50% by weight inorganic filler is oriented in the machine direction to increase yield and tensile strength, and reduce gauge variation to improve print qualities.
First claim
Opening claim text (preview).
What is claimed is: 1 . A flexible packaging film comprising a blown film comprising high density polyethylene resin and at least 50% by weight inorganic filler, wherein said blown film has been oriented in a machine direction to a final thickness which is at least 35% less than an initial thickness. 2 . The film of claim 1 wherein said blown film comprises a thickness coefficient of variation of 10% or less. 3 . The film of claim 1 wherein said inorganic filler comprises at least one of talc, clays, silicon dioxide, diatamaceous earth, Kaolin, micas, gypsum, potassium nitrate, sodium chloride, metal chlorides, dolomite, bentonite, montmorillonite, metal sulfates, ammonium nitrate, sodium nitrate, titanium dioxides, and calcium carbonate. 4 . The film of claim 1 further comprising at least one skin layer on said blown film. 5 . The film of claim 4 wherein said at least one skin layer comprises at least one of EAA (ethylene acrylic acid), EVOH (ethylene vinyl alcohol), Nylon, HDPE (high density polyethylene), LDPE (low density polyethylene), LLDPE (linear low density polyethylene), PGA (polyglycolic acid), or PBS (polybutyl styrene).
