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.

Tongfeng Electronics Elastic Modulus The above parameters are non-technical agreement, for reference only. 5^ Curve of tensile strength 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)

8、Storage All kinds of vibration and shocks shall be avoided to the film rolls in storage and transportation. The rolls shall be stored not more than one year in a dry place. Temperature exceeding 30°C shall be avoided during transport and storage. If the film is stored for more than one year, the film properties shall beevaluated again.

9、Labelling Each roll is equipped with two labels, which are placed on the wooden plate and inside the bag, as below Contents of label label The self-adhesive label in red and grey shall be used to distinguish the winding direction of film roll. The labelcontaining the following contents shall be posted: Name of product Product model:sc44 SC44 TS12 ---------------------- High-class products for sale at home Specifications (thickness, width, length): 4.5µm（nominal thickness）, 910mm, 18500m Weight(net weight): 106.0kg Core: inner diameter of core: 6 inches Grade of product: high-class pro
