SJ-55 Double Layer PE Blown Film Extrusion Machine
High-Speed Nylon and PE Film Blowing Machine with Double Winders for Efficient Bag Production
Machine Overview
The SJ-55 Double Layer PE Blown Film Extrusion Machine is designed for high-efficiency film production using LDPE, LLDPE, or HDPE. With its dual-layer co-extrusion capability, it enhances film strength, barrier properties, and transparency—ideal for producing quality packaging films for bags, food packaging, and industrial use.
Detailed Description
The SJ-55 Double Layer PE Blown Film Extrusion Machine is built for manufacturers looking to produce strong, high-quality films for plastic and nylon bag production. Equipped with two high-performance extruders, this machine can co-extrude laminated or double-layer films in a single run—ideal for making grocery bags, pure water bags, T-shirt bags, and industrial sheeting.
It features an advanced co-extrusion die head for uniform material flow, air bubble formation for proper film shaping, and a double winder system that allows continuous operation without downtime. The dual winder uses automatic tension control and surface/center winding options to handle two finished film rolls simultaneously—boosting productivity and efficiency.
Whether you produce PE film or nylon film (as commonly referred to in Nigeria), this machine supports various film widths and thicknesses to meet your custom packaging needs.
Specific Applications of the SJ-55 Double Layer Film Blowing Machine
- Packaging Films: For food packaging, garment wrapping, and other applications where sealability and durability matter.
- Shopping & Nylon Bags: Ideal for producing T-shirt bags, pure water sachets, garbage bags, and retail carry bags.
- Industrial Films: Suitable for stretch wrap, barrier films, and specialty films requiring anti-slip or high tensile strength properties.
Technical Specifications
- Model Number: SJ-55 Double Layer
- Capacity: 40–50 kg/h
- Power Source: 18kw
- Film Width: Up to 800 mm
Key Features
- Two Extruders: Allows different materials or colors to be combined for double-layer film with different properties (e.g., strength and flexibility)
- Co-Extrusion Die Head: Merges the two melts into one high-quality film for added strength and versatility.
- Bubble Formation System: Air inflates the melt into a film bubble, which is then cooled and shaped with air rings.
- Double Winder: Twin winders operate simultaneously, enabling continuous roll changeover with less downtime and higher throughput.
- Precise Temperature Control: Multi-zone heating ensures accurate material melting and processing for consistent film quality.
