Crystal candy is highly sensitive to humidity and physical impact. The packaging must include moisture-proof barriers (such as silica gel desiccant packets) and hermetic sealing to prevent the sugar shell from softening. For B2B bulk orders, prioritize individual wrapping within a sturdy, shock-absorbent outer box to minimize breakage during transit. Ensure the labeling complies with the destination country's laws, including allergen warnings, ingredient lists in the local language, and expiration dates.
