Polyethylene film has become thinner over the years due to advancement in resin grades and film extrusion technology. While this has resulted in cost reduction for consumers, it has also made printing on such film more challenging, as thinner gauge polyethylene tend to elongate easily, thus rendering less accurate print registration.
Great Wall Plastic Industries has acquired modern flexographic presses equipped with central impression (CI) technology to meet the print quality expected in a very competitive and challenging consumer market. In a CI press, polyethylene film in printed around a drum, avoiding elongation problems that might exist in other printing technology. Such CI press system allows the printing of high quality designs on wide web film.
