Packaging With Modified Atmosphere

Kitinoja (2003) describe in more detail about the packaging with modified atmosphere as follows. On packaging intended for consumers: If the material characteristics and the characteristics of permeabilitasadalah appropriate, an atmosphere can evolve passively through consumption of O2 and production of CO2 during respiration. Cut vegetables fresh or processed mustard minimum can be packed in a plastic bag after a partial vacuum is created.

Gas mixture is then added 30 to 50% O2 and 4 to 6% of CO2 into the bag, and closed.

For shipping packaging: polyethylene plastic layer is added in the box in cherry shipments. Polyethylene plastic bags used to wrap banana marketing experience with travel that far.

For a pallet: The pallet-loads of products such as strawberries can be closed with polyethylene plastic milkantong 5 and strands or a plastic sheet on the pallet base using wide adhesive tape. Furthermore, the packaging is made of vacuum and put sedikti CO2 and 15% through a small hose.

Known various types of plastic for packaging, but very little plastic that has the permeability according to MAP. Polyethylene and polyvinyl chloride plastic Low density plastic main films used for packaging fruit vegetable segardan. Plastic and polyester have such low gas permeabilities that are only suitable for commodities with very low respiration rates.
