Films and Sheets Division (P-Plus^® freshness preserving films)

That is a packaging technology that restrain breathing of produces to the minimum level for freshness keeping. Fruits and vegetables are living after harvesting and they are breathing. To reduce respiring at low level is most important point for freshness keeping.
One of the way is to keep it under colder condition.
Second way is to keep surrounding gas to be low oxygen and high carbon oxidize condition.
It is called controlled atmosphere preservation.
MA can keep gas inside package to be high carbon oxidize condition. MA is abbreviation of Modified atmosphere.

It is effective basically. However, root crops have low respiring and not so effective. It is effective for cut root crops as these become high breathing condition after cutting. In addition, it is not effective for rice or pickles, as these do not breath.

MA is only effective for vegetables and fruits. As produces are living after harvesting, these can be controlled under low breathing condition. Freshness keeping of meat or fish is according to different principles.

It is not effective because frozen food does not breath.

It is necessary. Cooler track transportation is desirable.

P-Plus^® cannot prevent mold unfortunately.

Any films will do for P-Plus^®. Freshness keeping of P-Plus^® does not depend on film material property. Controlling of hole size and numbers of holes are key technology of P-Plus^®. However for vegetable package, transparence is required and transparent OPP films are used.

Dioxin is not generated in such case. Dioxin is generated when chlorinated resin material is burnt at low temperature. We do not use such chlorinated resin films for P-Plus^®.

P-Plus does not work when it is not sealed completely. Numbers of holes of P-Plus^® is from several to several ten. If P-Plus^® is not sealed CO2 is not controlled by hole size and numbers.

It is impossible actually. Breathing of produce has infinite variety by kind, place of growing, weight and cutting method. Therefore, P-Plus^® is basically made to order product. Single P-Plus^® film cannot be used for many kind of vegetables and fruits. Sometimes it can be used in the case different food has same breathing level.

P-Plus^® is delivered as a roll or a bag. We can provide rolled product for packaging or many kinds of plastic bag according to customer needs. It can be freely printed. as well.
