Water-Repellent Paper Packaging Box ( Non-contact Food Packaging Box )

Specifications

Water-Repellent Paper Packaging Box

( Non-contact Food Packaging Box )

Function / Use / Required Attention of KPE

The Shape of Water on KPE Paperboard becomes sphere like the image above,

when dropping water on the board, because of its water-repellency. 

 Remarkable Features *

The strength of KPE box would continue longer than normal box,

even under condition with dewy surface, because of its characteristics of water-repellency

and anti-freezing.

Thermal-insulating effect shall be expected by its high performance of air-interception.

KPE paperboard box shall not be easily spoiled in freezer or refrigerator.

Because the natural feather is used as the material,

KPE paperboard box shall be recycled in the same way as normal box.

* Themographic ditribution chart of surface of KPE box by infrared image analyzing devices. *

Temperature of outer surface of normal box including ice is low,

compared with outer surface of KPE box including ice.

And temperature of outer surface of KPE box is higher than that of normal box.

These results mean that there is cool efficency

by reducing the transference of temperature from inside to outside of box.

* Efficiency of Anti-Freezing *

Results in freezing comparison test of normal coruugated paperboard box and

KPE corrugated paperboard box are as follows.

Preparation :

1.Cut normal sheet and KPE sheet in size of 15cm by 15cm.

2.Fold every side in 1cm, not in order to prevent the leakage of water.

3.Pour 20ml water into these sheets under 20°C(68°F) surroundings

   and then place them in the freezer.

Evaluation :

4.Leave the sheeets for 8 hours.

   And then, check the result of freezing comparison after removing the ice.

Even when sheet surface of KPE is frozen, ice on surface can be easily removed.

There is no contamination and weakened strength on surface as well.

* Examples of Typical Use of KPE Paperboard Box in Japan *

KPE box has ever been used as the alternative instead of foam polystyrene,

because of its excellent performance of water-repellency and intercepting air.

Use plastic bag for ice in KPE paperboard box to avoid water leakage. Shut the bag completely, when you set the box (ex.broccoli box) for transportation.	Gift box of frozen Katsuo-no-Tataki    in Japanese     (lightly-roasted bonito).

* Attention *

Pay attention to handle KPE box as same as handling normal corrugated box.
 
The surface of linerboard has water-repellent effect.

But, normal type of medium paper and glue is used.

And so, the strength of KPE box shall be weakened if you include

water and ice directly in the box and if you use KPE box out of doors,

because water enters the edges of box as same as normal box.

Seal the edges of KPE box completely with plastic tape in order to

avoid the weakening of the box, in case of the above.
 

Use working gloves to protect your hands when you assemble KPE box.

Do not assemble KPE box with bare hands,

because it is dangerous for your hands to be injured.
 

Do not make holes, cut-in, and defects on KPE box in order not to

lose its thermal-insulating efficiency, when you assemble KPE box.
 

Oil might sink into the surface of KPE box, when oil is stick on its surface.
 

Use permanent markers for writing something on the surface of KPE paperboard or KPE box.

But water-repellency on the written part with permanent marker becomes somehow ineffective.
 

Confirm that applied ink for printing on the surface of KPE

and applied glue for forming boxes with KPE is suitable and effective.
 

Use high-strength adhesive type of tape or sealer for KPE box,

because the surface of KPE has extremely high water-repellent characteristics.

And make sure that KPE box is sealed properly with used tape or sealer,
before assembling KPE box.
 

Do not use KPE paperboard and KPE paperboard box for any other purpose than packing or wrapping.
 

Caution : Do not use KPE products as toys or playing tools. And pay full attention to children for avoiding possible accident.
 

Quarantine : Our“KPE”Corrugated Paperboard Box includes feather.

We cannot confirm if there are problems on Quarantine about feather or not in buyer’s country.

Please confirm it by yourself in your country.
 

Bird-influenza : Life of virus of bird-influenza is said to be about four days under 22°C(72°F). Feather for KPE was completely cleaned in advance, and was heat-treated in its converting process.
 

At the time of delivery, several weeks have already passed, so there is no danger of catching
bird-influenza caused by feather of KPE.
