Deep Expertise, Advanced Engineering | Introducing the Three-Layer Co-Extrusion Blown Film Machine

The manufacturing of high-end films places rigorous demands on equipment stability and forming precision—an area where Chaoxin consistently focuses its R&D efforts.

A brand-new three-layer co-extrusion blown film machine has been unveiled, designed primarily for the production of cold-stretch hooding film and utilizing a proven 30%/40%/30% three-layer composition ratio.

The machine features a 13-meter vertical frame and accommodates a maximum film width of 2050 mm. It handles thicknesses ranging from 0.04 mm to 0.15 mm, with a stable production capacity of 250–350 kg/h—precisely meeting the requirements for cold-stretch sleeve film orders.

Equipped with a Taiwan Hongling IBC (Internal Bubble Cooling) die head, featuring ceramic heating elements to ensure stable temperature control; integrated with a Defini automatic air ring and a capacitive contact-type automatic thickness measurement system, enabling closed-loop regulation to strictly control film thickness deviation.

The frequency converter is integrated with the IBC internal cooling system for coordinated control; a Russian-language interface option has been added to accommodate overseas customers.

The dual-winding system features air-expansion shafts on both sides and a lifting mechanism with suspension hooks. A dedicated operating platform is positioned above the dual-winding unit, complete with guide rails for die changes and an electric hoist, making maintenance and die replacement both convenient and efficient.

A familiar domain, backed by the confidence that comes from deep, sustained expertise.

Chaoxin remains committed to exploring the intricacies of manufacturing processes, empowering clients to confidently take on orders for high-specification films.
