3. Appearance Parameter
No. | Item | Discription |
1 | Crystal point, carbon point | a small amount can be allowed ( at most 2 carbon-points per 1m length ) |
2 | Scratch,bubble,dirt,stain …etc | Can’t be allowed, but PVDC material itself sour taste and ozone smell generates while deal with radiation crosslinking can allow. |
3 | Sealing parts | non-virtual sealing phenomenon |
4 | wrinkle | a slight intermittent wrinkles can be allowed. |
5 | Shape of sealed | straight line end sealed, curve end sealed , flank sealed. |
