Each pack features an image of an animal created by body-painting artist Emma-Jane Cammack. The redesign will be backed by a programme of sampling at events such as the London Food Festival and the BBC Good Food Show in Birmingham.
Managing director Crispin Clay said: "We are the leading brand in seed snacks and want our packaging to shout 'fun and tasty' plus have greater shelf presence.
We want to encourage nutritious nibbling in a lively yet stylish fashion."
The seven-strong range is available in 30g sachets (rrp 45p), 200g tubs (rrp £2.99) and 500g tubs (rrp £5.99).
