Plastic film detection

[Projects] China plastic film industry is in a stage of vigorous development, it reported that the demand for Chinese plastic film to grow at an annual rate of over 9%. From the applications of the plastic film, the amount of the largest, most varieties, the most widely used by the packaging industry, their consumption accounts for about 2 // 3, used in food packaging, electronics packaging, commodity packaging, clothing and packaging. Material point of view, the largest amount of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), ethylene / vinyl acetate (EVA), polyamide (PA) made of a resin such as a plastic film. With a variety of new materials, new equipment and new technology constantly emerging, we will promote China's plastic film toward species diversity, specialization and versatility with a composite film direction.
