Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

1. A method of making a storage bag, comprising: a) manipulating a first material using a first tool to create a first portion having at least a first closure element, the first closure element having a channel and an elongated member extending along a base of the first closure element;b) manipulating a second material using a second tool to create a second portion having a flat or substantially flat surface;c) creating a first sidewall by joining the first portion and the second portion overlapping edge to edge along the base of the first closure element, the first sidewall having the first portion with the first closure element and the second portion having the flat or substantially flat surface;d) creating a complementary first portion having a second closure element, the second closure element having an elongated member and a channel extending along a base of the second closure element;e) creating a second sidewall by joining the complementary first portion and a complementary second portion overlapping edge to edge along the base of the second closure element, the second sidewall having the complementary first portion with the second closure element and the complementary second portion having a flat or substantially flat surface;f) aligning the first sidewall and the second sidewall such that the first closure element and the second closure element together form a double-locking closure mechanism; andg) forming parallel or substantially parallel double seals with a gusset between the double seals, along three sides of the first sidewall and the second sidewall, leaving an opening through the double-locking closure mechanism. 2. The method according to claim 1, further comprising: h) forming a first corner seal at a first corner of the first sidewall and the second sidewall, the first corner seal reinforcing a first end of the double-locking closure mechanism; andi) forming a second corner seal at a second corner of the first sidewall and the second sidewall, the second corner seal reinforcing a second end of the double-locking closure mechanism. 3. The method according to claim 2, wherein steps g), h), and i) are performed simultaneously or separately. 4. The method according to claim 2, wherein forming the first corner seal comprises using a mold and injecting or directing the first material into the mold. 5. The method according to claim 1, wherein the first tool comprises an extrusion plate with an opening for forming the channel and the elongated member. 6. The method according to claim 1, wherein step c) is performed using radio frequency (RF) welding. 7. The method according to claim 1, wherein the first material is a blend of ethylene vinyl acetate (EVA) and polyethylene (PE). 8. The method according to claim 7, wherein the blend comprises approximately 90% or more EVA and approximately 10% or less PE. 9. The method according to claim 8, wherein the first material and the second material are same or different. 10. A storage bag made by the method according to claim 1. 11. A method of making a storage bag, comprising: a) manipulating a first material using a first tool to create a first portion having at least a first closure element, the first closure element having a channel and an elongated member extending along a base of the first closure element, wherein the first material is a blend of ethylene vinyl acetate (EVA) and polyethylene (PE);b) manipulating a second material using a second tool to create a second portion having a flat or substantially flat surface;c) creating a first sidewall by joining the first portion and the second portion overlapping edge to edge along the base of the first closure element, the first sidewall having the first portion with the first closure element and the second portion having the flat or substantially flat surface;d) creating a complementary first portion having a second closure element, the second closure element having an elongated member and a channel extending along a base of the second closure element;e) creating a second sidewall by joining the complementary first portion and a complementary second portion overlapping edge to edge along the base of the second closure element, the second sidewall having the complementary first portion with the second closure element and the complementary second portion having a flat or substantially flat surface;f) aligning the first sidewall and the second sidewall such that the first closure element and the second closure element together form a double-locking closure mechanism; andg) forming parallel or substantially parallel double seals with a gusset between the double seals, along three sides of the first sidewall and the second sidewall, leaving an opening through the double-locking closure mechanism. 12. The method according to claim 11, wherein the blend comprises approximately 90% or more EVA and approximately 10% or less PE. 13. The method according to claim 11, wherein the first material and the second material are same or different. 14. The method according to claim 11, further comprising: h) forming a first corner seal at a first corner of the first sidewall and the second sidewall, the first corner seal reinforcing a first end of the double-locking closure mechanism; andi) forming a second corner seal at a second corner of the first sidewall and the second sidewall, the second corner seal reinforcing a second end of the double-locking closure mechanism. 15. The method according to claim 14, wherein steps g), h), and i) are performed simultaneously or separately. 16. A method of making a storage bag, comprising: a) manipulating a first material using a first tool to create a first portion having at least a first closure element, the first closure element having a channel and an elongated member extending along a base of the first closure element;b) manipulating a second material using a second tool to create a second portion having a flat or substantially flat surface;c) creating a first sidewall by joining the first portion and the second portion overlapping edge to edge along the base of the first closure element, the first sidewall having the first portion with the first closure element and the second portion having the flat or substantially surface;d) creating a complementary first portion having a second closure element, the second closure element having an elongated member and a channel extending along a base of the second closure element;e) creating a second sidewall by joining the complementary first portion and a complementary second portion overlapping edge to edge along the base of the second closure element, the second sidewall having the complementary first portion with the second closure element and the complementary second portion having a flat or substantially flat surface;f) aligning the first sidewall and the second sidewall such that the first closure element and the second closure element together form a double-locking closure mechanism;g) forming parallel or substantially parallel double seals with a gusset between the double seals, along three sides of the first sidewall and the second sidewall, leaving an opening through the double-locking closure mechanism;h) forming a first corner seal at a first corner of the first sidewall and the second sidewall, the first corner seal reinforcing a first end of the double-locking closure mechanism; andi) forming a second corner seal at a second corner of the first sidewall and the second sidewall, the second corner seal reinforcing a second end of the double-locking closure mechanism. 17.
