the film is manufactured with high purity, high isotacticity polypropylene.It has high BDV,excellent mechanical strength.

Different Types:

 

 

 Cores:

Material:plastic

Width:Film Slit Width 0.2mm

Inner Diameter:75mm+1.0mm/-0

Roll Outer Diamter:

for slit widths 25.0mm up: 240+10/-20mm

for slit widths 50.0mm up: 320+10/-40mm

for slit widths 10.0mm up: 180+8/-18mm

for slit widths 4.0mm up: 155+6/-15mm

 Rolls:

Film is wound on solid cores, with the metallized layer inside.

Rolls are wound up to the specific outer diameter.

the loose end of film is held in place by a closing sticker.

Rolls are always packed in pairs.

There is a plastic foam between the rolls to protect the electrode side.

 Characteristics:

Posses excellent self-healing performance

Strong antioxidant properties

Excellent metallization property

Film adhesive attraction

Lower variation of thickness

Good performance

 Packing:

Inner:

1,the piled rolls are packed in plastic bag and heat-sealed with desiccants after vacuum removal

2,Labels inside the bags mark film class, type, thickness, width,free margin width and resistance.

Outter:

1,the bags are packed in carton cases.

2,the carton cases are packed in wooden cases or reinforced carton.

 Storage:

Metallized Film should be stored in its original packing until use. the temperature should be controlled to 5~35c and humidity less than 85% RH.

on exposure to moisture, the thin metallized layer is likely to be easily oxidized. Therefore, after the packing is opened, the rolls should be used as soon as possible.

It is rerecommend that the opened rolls be stored in temperature conditions of 15-25c and humidity of less than 60%RH.

Metallized Film kept sealed on the original packing and stored as described above is guaranteed according to the following conditions:

Al metallized film: 12 months from the delivered date.

Al/Zn Alloy metallized film: as Zn is relatively unstable,preservation period depends on the resistance of film.

10 Ohms or less: 6 months(from delivery date)

10 to 15 Ohms: 3 months(from delivery date)

15 Ohms: 1 month(from delivery date)
