Uses:
1) courier envelope window film or gift packaging box with window film. A lot of business letters need to open the window design, the various mailing tariff notification, such as: telecommunications, banks, government agencies, etc.. And the original cassette packaging steering fenestration packaging.

is an envelope manufacturer, bulk mail, the mail sorting business, postal operators, OPS
film can bring you better work efficiency and economic benefits. 

2. Feature:
- Has a very good anti-static ability.
- The smoothness of a good film, the production process in an envelope will rarely produce
a result of thin film and mechanical standstill.
- Film slitting good, with high-intensity endurance, meanwhile horizontally easily torn,
very suitable for the production of high-speed operation of the envelope.
- Low-cost, in China and Japan are using the standard 25um thickness, and other companies
produced BOPS Materials 27um, 29um, compared the cost of a cheap film envelopes 8% ~ 16%.
