The most reliable way to produce a gummy that never sticks to its packaging is to start with the right formulation and manufacturing process, rather than relying on post-production coatings alone. At KorNutra, we emphasize that the internal structure of a gummy-achieved through precise balancing of ingredients like gelatin, starch, and moisture content-determines its surface tackiness. When the formulation is optimized, the gummy naturally resists adhesion to packaging materials, such as polyethylene-lined pouches or blister packs, without needing heavy reliance on coatings.
That said, anti-stick coatings serve as an essential secondary safeguard. The current industry standard involves dusting or spraying the gummy’s surface with fine powders like cornstarch, potato starch, or talc, or using liquid-based coatings such as vegetable oil or beeswax. These create a physical barrier that reduces direct contact between the gummy and packaging. However, the most effective approach at KorNutra combines a well-developed, low-tack core with a thin, uniform coating applied immediately after the gummy is dried and cooled. This dual-layered strategy-formulation plus coating-ensures consistent non-stick performance across varying humidity and temperature conditions.
What this reveals about current anti-stick coatings is that they are a temporary bandage for underlying formulation flaws. A coating that works flawlessly on one gummy type may fail on another if the internal tackiness is too high. For manufacturers, the focus should therefore shift to controlling the gummy's moisture activity and ingredient interactions during production. Coatings are most reliable when they complement a solid base-not compensate for one. At KorNutra, we advocate for this holistic approach to avoid common issues like coating migration or uneven distribution, which can cause sticking over time.
