Abstract
A method for producing zeolite embedded polyolefin films for packaging polyurethane foams also embedded with zeolite.
Claims15
A product comprising:
- (1) a film including:
- a monolayer or multi-layer film having at least one layer comprising a formulated resin;
- wherein the formulated resin comprises:
- a low density polyethylene (LDPE) wherein the LDPE has a density of from 0.915 g/cc to 0.925 g/cc and a melt index, I2, of from 0.1 g/10 min to 1 g/10 min, or
- a linear low density polyethylene (LLDPE) wherein the LLDPE has a density of from 0.915 g/cc to 0.945 g/cc and a melt index, I2, from 0.1 g/10 min to 1 g/10 min, and
- at least a first silica containing zeolite with a Si/Al molar ratio of greater than 35 and a grain size from grain size of from 250 nm to 2000 nm, and
- (2) a flexible polyurethane foam being the reaction production of an isocyanate component and an isocyanate-reactive component, the flexible polyurethane foam including at least a second silica containing zeolite, the silica containing zeolite having an Si/Al molar ratio of greater than 35 and a grain size of from 250 nm to 2000 nm.

A method of packaging a polyurethane foam, comprising:
- placing a polyolefin film within packaging of the polyurethane foam, wherein the polyolefin film comprises:
- a monolayer or multi-layer film having at least one layer comprising a formulated resin;
- wherein the formulated resin comprises:
- a low density polyethylene (LDPE) wherein the LDPE has a density of from 0.915 g/cc to 0.925 g/cc and a melt index, I2, of from 0.1 g/10 min to 1 g/10 min, or
- a linear low density polyethylene (LLDPE) wherein the LLDPE has a density of from 0.915 g/cc to 0.945 g/cc and a melt index, I2, from 0.1 g/10 min to 1 g/10 min, and
- at least a first silica containing zeolite with a Si/Al molar ratio of greater than 35 and a grain size from grain size of from 250 nm to 2000 nm, and wherein the polyurethane foam is comprised of:
- at least one isocyanate-reactive component;
- and
- at least a second silica containing zeolite, wherein the silica containing zeolite has an Si/Al molar ratio of greater than 35 and a grain size of from 250 nm to 2000 nm.
