Pistachio packing machines

For Japan, where people like special colors Iranian Pistachio and graphic designs, pistachios are prepared in special packaging and printing. Califoia pistachios are packed in plastic packages using FFS vertical machines. The bags are zippers. And they have the property of re-sealing. The price of these packages is cheap and it is marketed under the brands of Ino Lock and Janoflex.

This packing machine has been widely used since 1970 and has now undergone many changes, so that the machine is capable of packing 60 bags per minute. The machine can be adjusted to produce packages with different dimensions. In these packages, the zipper part is made of LLDPE. The thickness of the film is 21.2 mm made of LLDPE laminated with polyvinyl chloride with a polyester coating and a printable polyester layer, which is printed in four to eight colors.

In a study, Good and Sautar (1995) considered the main cause of corrosion of kidneys in packages of nuts as inadequate stitching and penetration of oxygen into the package, and the analysis of volatile gases as the presence of oxygen and hexane in these packages that were kidneys. The researchers showed that the LDPE / Ionomer coagulation layer was a more suitable layer for sewing wrappers than the PE / EVA bilayer film.

In addition, PET / PVDC and OPP / EVOH films are suitable films for packing nuts in terms of their resistance to moisture and gases, especially oxygen. These plastic films can be used for packaging raw dried pistachios or roasting data using FFS type packaging machines.
