Abrasion resistant heat shrinkable multilayer film

A packaged product comprising:

• a. a support structure exhibiting a shape;
• b. a product situated within the support;
• c. a multilayer heat-shrinkable film encapsulating the support thereby isolating the product from an external environment;
• the multilayer heat-shrinkable film comprising:
• i. a sealant layer comprising between 30-49.99 wt % of a homogeneous polyethylene copolymer having a density from 0.91 to 0.93 g/cm3, between 50-69.99 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 0.01-0.4 wt % of a member selected from the group consisting of natural silica, synthetic silica, ceramic spheres, diatomaceous earth, kaolin, and mica;
• ii. at least two substrate layers comprising an ethylene/vinyl acetate copolymer;
• iii. a core layer comprising between 70-90 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 10-30 wt % of a very low density ethylene/octene copolymer having a density less than 0.915 g/cm3;
• and
• iv. a skin layer comprising between 30-39.99 wt % of a homogeneous ethylene/hexene copolymer having a density from 0.91 to 0.93 g/cm3, at least 10 wt % of a high density polyethylene homopolymer having a density of at least 0.95 g/cm3, and between 50-59.99 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 0.01-0.4 wt % of a member selected from the group consisting of natural silica, synthetic silica, ceramic spheres, diatomaceous earth, kaolin, and mica;
• wherein the multilayer heat-shrinkable film has an oxygen transmission rate of between 2000 to 9000 cm3 (STP)/(m2-day-1 atm) at 40° C. and 0% relative humidity measured in accordance with ASTM D3985.

A method for packaging a product comprising the steps of:

• a. providing a support structure which retains its shape while supporting a product;
• b. situating a product within the support;
• c. encapsulating the support with a multilayer heat-shrinkable film thereby isolating the product from an external environment;
• the multilayer heat-shrinkable film comprising:
• i. a sealant layer comprising between 30-49.99 wt % of a homogeneous polyethylene copolymer having a density from 0.91 to 0.93 g/cm3, between 50-69.99 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 0.01-0.4 wt % of a member selected from the group consisting of natural silica, synthetic silica, ceramic spheres, diatomaceous earth, kaolin, and mica;
• ii. at least two substrate layers comprising an ethylene/vinyl acetate copolymer;
• iii. a core layer comprising between 70-90 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 10-30 wt % of a very low density ethylene/octene copolymer having a density less than 0.915 g/cm3, and
• iv. a skin layer comprising between 30-39.99 wt % of a homogeneous ethylene/hexene copolymer having a density from 0.91 to 0.93 g/cm3, at least 10 wt % of a high density polyethylene homopolymer having a density of at least 0.95 g/cm3, and between 50-59.99 wt % ethylene/octene copolymer having a density from 0.93 to 0.95 g/cm3, and between 0.01-0.4 wt % of a member selected from the group consisting of natural silica, synthetic silica, ceramic spheres, diatomaceous earth, kaolin, and mica;
• wherein the multilayer heat-shrinkable film has an oxygen transmission rate of between 2000 to 9000 cm3 (STP)/(m2-day-1 atm) at 40° C. and 0% relative humidity measured in accordance with ASTM D3985.
