[Identification] select the appropriate method in infrared spectroscopy, take each layer of material, inspect according to spectrophotometry (People's Republic of China Pharmacopoeia 2000 edition Appendix ⅣC), inspect result shall meet the requirements. (Aluminum, paper ingredients may not be identified as above).
[Appearance] take right amount of composite films in bright area of the natural light, and visual inspect. Composite films shall not have defects such as perforations, foreign matter, odor, adhesion, composite layer separation and significant damage, bubbles, wrinkles, dirt and etc.
[Barrier properties] Water vapor permeability - Test method is in line with vapor permeability for plastic films and laminated sheets specified in GBl037-88 Cup method.

When customer asks inquiry for composite film, he has
to offer us width of composite film, and whether the composite film
shall be printed or not. We are willing to offer customers composite
film sample without charge for his test, if customers test machine
is bought from China, we are willing to send the asked sample to the
test machine manufacture.
