In industries like electronics, construction materials, and aerospace that demand high material stability, the batch consistency of protective films directly affects downstream production efficiency. How does Shenzhen Guangdayuan Film Co., Ltd. ensure stable quality across every batch?
As a leading enterprise with over 20 years of industry experience, Guangdayuan has established a full-process control system from the source. In raw material procurement, it strictly selects suppliers and conducts batch sampling inspections on PE, PVC, and PET substrates to ensure uniform performance of base materials. During production, intelligent monitoring systems are installed on blow molding machines and coating machines in its 16,000-square-meter standardized factory, recording key parameters such as temperature and pressure in real time to avoid human operation errors.
Through industry-university-research cooperation with Harbin Institute of Technology, Guangdayuan has standardized process parameters. Indicators like the tensile strength of PE protective films and light transmittance of PET films are set with threshold ranges via digital models. Each batch of products undergoes 3 inspections under the ISO9001 system, covering 12 core indicators including thickness deviation and viscosity stability, with third-party test reports archived simultaneously.
This strict control enables stable application in multiple fields: precision component packaging in the electronics industry requires viscosity error of ≤2% per batch of protective films; outdoor stick film in the construction materials sector demands that weather resistance parameter fluctuations be controlled within 5%. Now, from medical equipment packaging to aerospace component protection, Guangdayuan's batch consistency has become an invisible industry standard.#Building protective film#
