Production Process of PVA Water-Soluble Film Production Line
The production of PVA water-soluble film requires multiple consecutive processes, with all links cooperating to ensure product quality. Blesson’s PVA Water-Soluble Film Production Line and PVA Water-Soluble Film Equipment integrate advanced technology and precision engineering, 性能优异. The specific process is as follows:

⦁ Raw Material Pretreatment and Reaction Stage of the PVA Water-Soluble Film Production Line
Production starts with the reaction tank: after raw materials are put into the reaction tank, auxiliary media such as water, steam, and compressed air are introduced simultaneously, and the materials react under specific conditions. This link provides qualified initial materials for the Water-Soluble Film Casting Line and PVA Film Casting Machine. The gas-liquid mixture generated by the reaction then enters the gas-liquid separation link; waste gas is discharged by a vacuum pump, and waste liquid and wastewater are collected and treated separately.

⦁ Material Conveying and Preliminary Filtration Stage of the PVA Water-Soluble Film Production Line
The reacted materials are conveyed by a rotor pump, first passing through a coarse filter to remove large impurities, then flowing into a sedimentation tank for further sedimentation and separation. This step provides a clean material foundation for the subsequent processes of the PVA Water-Soluble Casting Film Machine. The settled materials are temporarily stored in a storage tank (this step is optional, meaning it can be flexibly adjusted according to actual production needs and is not a mandatory process).
随后, the materials are accurately conveyed by a gear pump to ensure the stability of material supply for the PVA Water-Soluble Film Production Line.

⦁ Fine Filtration and Film-Forming Preparation Stage of the PVA Water-Soluble Film Production Line
After flowing out of the storage tank, the materials undergo fine filtration through a precision filter to ensure full removal of impurities. Then, under the temperature control of a mold temperature controller, the materials enter the die head to prepare for film formation. This process is a key preliminary step for the PVA Film Coating Production Line and Laundry Detergent Pods Film Making Machine to achieve high-quality film formation. 在此过程中, an air suction knife assists in shaping the initial form of the film.

⦁ Film-Forming and Setting Stage of the PVA Water-Soluble Film Production Line
The materials flowing out of the die head adhere to the steel belt; the hydraulic deviation correction device ensures the stable operation of the steel belt and prevents deviation. This device is a core component for the PVA Film Casting Machine and Water-Soluble Film Casting Line to ensure film-forming accuracy. 随后, the materials enter an oven heated by an oil furnace together with the steel belt; the oven adopts reasonable heating methods such as zoned heating to dry and set the materials. The waste steam and water vapor generated during the process are discharged and collected to ensure the environmentally compliant operation of the PVA Water-Soluble Film Production Line.

⦁ Post-Treatment and Finished Film Winding Stage of the PVA Water-Soluble Film Production Line
The film material treated by the oven is pulled by a traction device, passing through a defect detector (for detecting surface defects) and a thickness gauge (for accurately measuring thickness) in sequence. This dual inspection provides quality assurance for the film required by the Laundry Detergent Pods Film Making Machine. 与此同时, an edge trimmer cuts off the irregular parts of the film edge (the edge scraps are collected and treated). 最后, the qualified film material is wound into large film rolls by a winder, completing the production of PVA water-soluble film. The entire process is suitable for the standardized operation requirements of the PVA Water-Soluble Casting Film Machine and PVA Water-Soluble Film Equipment.

Throughout the entire production process, various types of equipment cooperate precisely, and key parameters such as temperature, 压力, and filtration accuracy are strictly controlled to ensure that high-quality PVA water-soluble films are produced for various application scenarios of the PVA Water-Soluble Film Production Line.
