Production Features

The 1200-1800mm Dual Winder PVC Cast Film Machine runs on an extrusion process, meaning raw PVC composite material gets melted and pushed through a die to form a continuous, flat sheet of film rather than the round tube shape you'd get from a blown film machine. Because PVC film is meant for direct food contact and needs to cling tightly and stay clear, the process has to avoid a specific defect known as "fish-eye" bubbles — small, uneven spots in the film that show up when the material isn't extruded cleanly. This machine's screw and extruder die are built specifically to prevent that problem, which matters a lot for buyers whose end customers expect a clean, transparent film with no visible flaws. The 1200-1800mm Dual Winder PVC Cast Film Machine is designed to support stable film production and help maintain consistent film quality during continuous operation.

The whole line is run through a PLC control system with a touchscreen interface, and it's set up with a full panel of operating buttons, which keeps day-to-day operation more straightforward and safer for the people running it. On the output side, it comes with a dual-shaft winder, meaning the finished film gets wound onto two separate shafts rather than one — a detail that matters for plants wanting to keep production moving without stopping the line every time a roll is finished.

Specific Applications
Vegetable packaging — wrapping fresh produce for retail display and extended shelf freshness
Fruit packaging — sealing fruit trays and individual items to slow moisture loss and maintain appearance
Meat packaging — wrapping fresh and processed meat products where clarity and cling strength both matter for retail presentation
Seafood packaging — sealing seafood products that require both moisture control and cold-chain compatible packaging
Dough and prepared food packaging — wrapping dough and similar prepared food items that need a tight seal to stay fresh
General cold-preservation food packaging — any food product requiring refrigerated storage where a clear, clinging film helps maintain freshness and presentation
Building material and material handling packaging — Chaoshun's cast film extrusion lines are also used across building materials, and material handling applications, so this line's underlying cast film technology isn't limited strictly to food use cases

Core Functions
1. Extrudes PVC composite material into continuous cast film through a high-efficiency extrusion screw
2. Prevents "fish-eye" bubble defects through the screw and advanced production technology
3. Maintains stable operation at high production speeds through the extruder die design, supporting a high yield of finished film
4. Produces film in a width range of 1200mm to 1800mm
5. Winds finished film using a dual-shaft (2-shaft) winder configuration
6. Runs the full production process through a PLC system with touchscreen control

FAQ

Q1: What is this 1200-1800mm Dual Winder PVC Cast Film Machine used to produce?
PVC cling film (cast film), primarily for food preservation and packaging purposes.

Q2: What does "fish-eye" bubble prevention mean, and why does it matter?
Fish-eye bubbles are small defects that can appear in extruded film. This machine's screw and production technology are designed to prevent them, which helps maintain the film's clarity and overall quality.

Q3: What's the benefit of a dual-shaft winder over a single-shaft one?
A dual-shaft winder allows the machine to continue winding film on a second shaft while a completed roll is removed from the first, reducing downtime compared to a single-shaft setup.
