Fruit & food guide

Blueberry and berry packaging guide

Blueberries and other berries are sold in small, clear packs, from the 125 g (4.4 oz) standard to 500 g family and 18 oz club packs. Berries are firm enough to stack deeper than strawberries, but they still need ventilation and gentle handling.

Written and reviewed by the AVI technical team, from AVI Global Plast's own catalogue and production data · Updated

Sizes

  • 125 g / 4.4 oz: the standard retail blueberry pack, also used for raspberries and blackberries.
  • 200–250 g: larger everyday packs.
  • 500 g and 18 oz: family, value and club-store packs.
  • 1 pint: used in the US for mixed berries and larger fruit.

Clamshell or heat-seal

Clamshells dominate berries because packing is fast and the pack re-closes. Heat-seal punnets such as the A-30 range are lighter, ship more packs per carton and suit tamper-evident or modified-atmosphere lines.

Shipping space

Blueberry packs are small and light, so freight is mostly air. A pack that nests deeply, or a shape that fills the outer box without gaps, lowers the cost per kilo shipped; ask AVI's team about space-saving formats.
