Frosted transparent film degree Test Method
1 Scope
This standard specifies the test methods for transparent plastic film spent grinding degree.
This standard applies to biaxially oriented polypropylene (BOPP), biaxially oriented polyamide (BOPA), cast polypropylene (CPP), biaxially oriented polypropylene
A variety of transparent plastic film wear and abrasion degree flower flower Determination of ester (BOPET), polyethylene (PE), the coating film, matt film and the like.
This standard specifies the observation method (Method A) applies to the case without reference to the kind of gloss difference ratio method (Method B) and haze difference method (square
Method C) applicable to the reference to the kind of situation.
Note. The coating film and matt film is not recommended to use C.
