Systems and methods for forming dual layer water soluble packets
A method of forming dual layer water soluble packets includes drawing a base film into a cavity of a mold, drawing air through openings in the base film, metering an amount of a first product of a first color onto the base film in the cavity, metering an amount of a second product of a second color onto the amount of the first product, and, sealing a lid film to the base film.
1. A method of forming dual layer water soluble packets, comprising:
drawing a base film into a cavity of a mold;
drawing air through openings in the base film;
metering an amount of a first product of a first color onto the base film in the cavity;
metering an amount of a second product of a second color onto the amount of the first product; and,
sealing a lid film to the base film.
2. The method according to claim 1 , further comprising cutting the openings in the base film with a laser.
3. The method according to claim 1 , further comprising cutting the openings in the base film with a laser before the base film is drawn into the cavity.
4. The method according to claim 1 , further comprising cutting the openings in the base film with a laser after the base film is drawn into the cavity.
5. The method according to claim 1 , further comprising forming the openings in a base film with water.
6. The method according to claim 1 , further comprising forming the openings in the base film with a mechanical piercing member.
7. The method according to claim 1 , further comprising increasing a density of the first product and the second product by drawing air through the openings.
8. The method according to claim 1 , wherein the first color and the second color are different.
9. The method according to claim 1 , further comprising compacting the first product and the second product in the base film in the cavity.
10. A method of forming dual layer water soluble packets, comprising:
drawing a base film into a cavity of a packet forming assembly;
forming one or more openings in the base film with a laser;
vacuuming air through the openings in the base film;
metering an amount of a first product onto an upper side of the base film in the cavity while applying a vacuum to a lower side of the base film; and,
metering an amount of a second product onto the amount of the first product while applying the vacuum to the lower side of the base film.
11. The method according to claim 10 , further comprising increasing a density of the first product and the second product by the vacuuming.
12. The method according to claim 10 , further comprising drawing air through the openings while metering the first product and the second product.
13. The method according to claim 10 , further comprising forming the openings in the base film with the laser before the base film is drawn into the cavity.
14. The method according to claim 10 , further comprising forming the openings in the base film with the laser after the base film is drawn into the cavity.
15. The method according to claim 10 , further comprising forming the openings in a base film with water.
16. The method according to claim 10 , further comprising forming the openings in the base film with a mechanical piercing member.
17. The method according to claim 10 , further comprising increasing a density of the first product and the second product by the vacuuming.
18. The method according to claim 10 , wherein the first color and the second color are different.
19. The method according to claim 10 , further comprising compacting the first product and the second product in base film in the cavity.
20. The method according to claim 10 , further comprising forming a boundary between the first product and the second product.
21. A method of forming dual layer water soluble packets, comprising:
forming openings in a base film;
drawing the base film into a cavity of a mold;
depositing an amount of a first product of a first color onto a first side of the base film in the cavity while applying a suction force to a second side of the base film;
metering an amount of a second product of a second color onto the amount of the first product while applying the suction force to the second side of the base film; and,
sealing a lid film to the base film.
