Suspension Wooden Pallet Packing
BOPET Film for Thermal Transfer Ribbons type TTR
1、 Characteristics
It is stretched in biaxial orientation by mean of flat film method by using
imported polyethylene terephthalate in electrical grade. With good mechanical
properties, and thermal characteristics, it has excellent engineering properties
in coating process.
2、 Applications
As a kind of substrate, it is widely applied to a variety of bar code printing,
advertising banner printing, label printing, photo printing and other industries.

4、Thickness Representation
The nominal value of the film thickness is indicated by the central value
(integer value, such as 3,5,7,10,15) of film thickness plus mantissa (one point after
decimal point) or its code. Our nominal value for BOPET film thickness is represented
in WMV.

7、Packaging
Two bags of desiccant and a label are put in eachfilm roll. For preventing from any
pollutant, each film roll shall be put into a plastic bag. And, foam gasket(about 4mm in
thickness)shall be put to separate the wooden plate for protectingthe end face of film roll.
And then, the film roll is put into the cartonwith adhesive tape to seal. Each tray of
products shall be wrapped with stretch film.（see below picture）
