Biodegradable And/or Home Compostable Sachet Containing A Solid Article
A sachet product that includes a biodegradable and/or home compostable sachet comprising a front film and a back film. In some examples, the front film and back film can include a middle layer that can contain paper with greater than 85% cellulose and an inner layer that can include different material, including but not limited to polyvinyl alcohol or polyhydroxylalkonate. The sachet can include a compartment adapted for storing a solid article where the solid article is an open cell foam. The open cell foam can include a water-soluble polymer and a surfactant.

- 1. A sachet product comprising a biodegradable and/or home compostable sachet comprising a front film and a back film comprising:
a. a front middle layer and a back middle layer comprising a paper having greater than 85% cellulose content; b. a front inner layer joined to the front middle layer and a back inner layer joined to the back middle layer wherein the front inner layer and back inner layer comprises an inner layer material selected from the group consisting of polyvinyl alcohol, polybutylene succinate, polybutylene succinate adipate, polyhydroxylalkonate, polyvinylidene chloride, carnauba wax, biodegradable thermo-plastic starch, and combinations thereof; wherein front inner layer and back inner layer being permanently joined around a perimeter to form a seal, the seal forming a compartment adapted for storing a solid article comprising an open cell foam comprising:
from about 10% to about 40%, by total weight of the article, of a water-soluble polymer;
from about 5% to about 80%, by total weight of the article, surfactant selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric surfactants, zwitterionic surfactants, and combinations thereof;
a Percent Open Cell Content of from about 80% to 100%;
an Overall Average Pore Size of from about 100 μm to about 2000 μm.
- 16. A sachet product comprising a biodegradable and/or home compostable sachet comprising a front film and a back film comprising:
a. a front middle layer and a back middle layer comprise a material selected from the group consisting of cellulose, cellulose acetate, metalized cellulose, metalized cellulose acetate, and combinations thereof; b. a front inner layer joined to the front outer layer and a back inner layer joined to the back outer layer wherein the front inner layer and the back inner layer comprise a material selected from the group consisting of polyvinyl alcohol, polybutylene succinate, polybutylene succinate adipate, polyhydroxylalkonate, carnauba wax, a biodegradable thermo-plastic starch, polyvinylidene chloride, and combinations thereof; wherein front inner layer and back inner layer being permanently joined around a perimeter to form a seal, the seal forming a compartment adapted for storing a solid article comprising an open cell foam comprising: from about 10% to about 40%, by total weight of the article, of a water-soluble polymer; from about 5% to about 80%, by total weight of the article, surfactant selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric surfactants, zwitterionic surfactants, and combinations thereof; a Percent Open Cell Content of from about 80% to 100%; an Overall Average Pore Size of from about 100 μm to about 2000 μm.
