Packing Lettuce & Loose Leaf vegetables:
Delicate Greens Require Special Treatment, packaging delicate vegetables such as lettuce or baby greens requires that additional care in weighing and processing in order to deliver the best product possible. In addition, hydroponic lettuce requires additional system design features to manage the larger and springier leaves compared to field-grown produce. 'Basil leaves' use Low Heat + Limited Contact: Ohlson Packaging’s lettuce packaging systems are designed to move the packaged lettuce very quickly through the vertical bagger, reducing any exposure to the heat produced by the machine itself. Additionally, the sealing process to form the bag itself can be controlled through the choice of film. Some films will be effectively sealed at lower heats, reducing any possible wilt in the bag. Modified atmosphere packaging is also important. We can recommend the right bags, clamshells, or other containers for your product.

The most classic system of pre-packaging is the use of a stretchable plastic film that adheres to the lettuce giving a very clean aspect; another option is micro-perforated polypropylene. The bags made of this material can be also used; the lettuces are packaged much quickly with this system. A widely spread method is the use of Flow Pack with loose lettuces or in covered trays. The units are placed in cardboard boxes of a unique height, although sometimes two or more levels are used. Inside the boxes, the lettuces are arranged in vertical position, one next to the others. There will only be one level in the case of " Iceberg" and " Trocadero’ lettuces, whereas the " Roman’ type is arranged horizontally, filling up to three levels. Baby lettuces are sometimes packaged in boxes or plastic baskets containing 2 to 4 units, weighing around 500g. In the last few years, other marketing systems like the ‘pre-cut’ lettuces have been created. The hearts are cut up, mixed and packaged together with other vegetables. This is carried out in controlled atmospheres, which helps to improve preservation.
