Developments in fresh produce packaging

摘要

Some changes are brought about by revolution, others by regular and steady evolution. But by whatever means it occurs, change is a constant factor in business and some-thing that continually occupies the minds of progressive growers. The last revolution in packaging for fruit and fresh produce was probably the introduction, and increasingly widespread use, of printed film to replace lids in packaging lines. Companies such as Proseal and Marco continue to respond to interest in high capital value machinery to apply flexible heat-sealed film lids instead of the traditional clip-on types, reducing the amount of plastic in a tray or punnet by 30 per cent. The machines put film lids on trays that have been filled in the field and test-weighed in the packing house. The ventilated lid is flexible, pre-printed polyester, 20 microns thick, from a roll.
