We provide regular perforation per customer order for all series of ZHONGCHENG films. When packaging equipment use its own perforation system, perforation quality directly affects the air evacuation during shrinking.Many old packaging machines cannot maintain good perforation quality, which results in seal problems and package quality issues. ZHONGCHENG can provide you with pre-perforated film rolls so there is no need to perforate on your equipment. Our high standard perforation quality provides better quality packages and reduced costs.
