Benefits of technology

[0009]In one aspect, a package includes at least one layer of foamed thin film having gaseous bubbles, void volumes, or cells. The foamed thin film includes a bio-based content of between about 10% and about 100%, a caliper of between about 10 and 250 microns, and a density reduction of between about a 5% to 50%, as compared to a non-foamed thin film of substantially the same caliper that does not comprise gaseous bubbles, void volumes, or cells.

Problems solved by technology

Much of the cost associated with such plastic film packages is the cost of the plastic resin that is used to make the film.
The redesign of the opening feature is costly in terms of engineering and evaluation time.
In addition, the redesign of the opening feature typically requires laborious a

Embodiment Construction

[0020]As used herein, the following terms have the following meanings:

[0021]“Agricultural product” refers to a renewable resource resulting from the cultivation of land (e.g., a crop) or the husbandry of animals (including fish).

[0022]“Bio-based content” refers to the amount of carbon from a renewable resource in a material as a percent of the mass of the total organic carbon in the material, as determined by ASTM D6866-10, Method B. Note that any carbon from inorganic sources such as calcium carbonate is not included in determining the bio-based content of the material.

[0023]“Biodegradation” refers to a process of chemical dissolution of materials by microorganisms or other biological means.

[0024]“Bio-identical polymer” refers to polymers that are made from monomers where at least one monomer is derived from renewable resources. For instance, a bio-identical polyolefin is made from olefins that are derived from renewable resources, whereas a petro-based polyolefin is made from olef...

Abstract

A package includes at least one layer of foamed thin film having gaseous bubbles, void volumes, or cells. The foamed thin film includes a bio-based content of between about 10% and about 100%, a caliper of between about 10 and 250 microns, and a density reduction of between about a 5% to 50%, as compared to a non-foamed thin film of substantially the same caliper that does not comprise gaseous bubbles, void volumes, or cells.

Description

FIELD OF THE INVENTION[0001]This application relates to the field of packages comprising a foamed film layer, and more specifically, to the field of packages that comprise a foamed film layer made at least in part of renewable, recyclable and / or biodegradable materials.BACKGROUND OF THE INVENTION[0002]Polyolefin-based plastic film is used to construct a wide variety of packages such as bags, pouches, labels and wraps that hold consumer goods. For example, bags holding stacks of disposable diapers or hygiene articles, pouches for wet wipes, and bags containing granular laundry detergent are often made from plastic film. The plastic film that forms a package may be a single layer of film (called a monofilm), or a combination of layers that can be co-extruded, fabricated as a laminate of separately produced layers that are adhered to one another, or fabricated as an extrusion lamination whereas one layer is extruded onto another previously formed layer(s).[0003]The specific composition...
