3 Layer Standard Co-Extrusion Blown Film Line

Engineered to Deliver Uniform Films with Operational Excellence.

The 3 Layer Standard Co-Extrusion Blown Film Line is a high-performance co-extrusion machine built for manufacturers who require consistent film quality, operational flexibility, and reliable output across a wide range of polymer materials. Part of the Oscillating Blown film Cooling (OBC) co-extrusion series, this three-layer blown film plant combines a simple yet robust mechanical design with advanced melt processing technology to deliver superior optical and mechanical film properties. Compatible with LL, LDPE, HM, HDPE, EVA, Bio-Degradable, and Bio-Compostable polymers, the machine is engineered to meet diverse production demands without compromising on efficiency making it a dependable choice for both established film producers and manufacturers looking to expand their capabilities.

With a production output ranging from 90 to 210 Kg/Hr and screw configurations at a 30:1 L/D ratio , in diameters of 45, 55, and 65 mm, this line ensures homogeneous mixing and melting of polymers for consistent melt quality across all three layers. The layflat range of 500 to 1350 mm combined with a thickness capability of 20 to 150 microns allows producers to manufacture both thin-gauge and heavy-duty films from the same plant, maximizing equipment utilization. Minimum gauge variation even at higher outputs, excellent bubble control, and enhanced gauge randomization further ensure uniform roll quality across extended production runs.

This blown film line caters to a wide spectrum of industrial and consumer applications. On the industrial side it efficiently produces general-purpose films, lamination films, tarpaulin films, and surface protection films. For consumer packaging , it supports courier bag films, LD shrink films, stretch films, shopping bags, water packaging films, milk pouches, atta packaging films, and bio-degradable films. It also caters to agricultural applications including mulch films and agroshed net films, reflecting its cross-industry versatility.

Q1. What is the production output capacity of the 3 Layer Standard Co-Extrusion Blown Film Line?

The machine delivers an output range of 90 to 210 Kg/Hr depending on the selected model and extruder screw diameter configuration. The entry-level SE3HR 900 model achieves 90 to 100 Kg/Hr, while the top-end SE3HR 1450-45/65/45 and SE3HR 1450-55/55/55 configurations reach up to 210 Kg/Hr, making the line suitable for both medium-capacity and high-volume film production operations.

Q2. What polymers and materials are compatible with the 3 Layer Standard Co-Extrusion Blown Film Line?

The machine is compatible with a wide range of polymers including Linear Low-Density Polyethylene (LLDPE), Low-Density Polyethylene (LDPE), High Molecular (HM) grade polyethylene, High-Density Polyethylene (HDPE), Ethylene Vinyl Acetate (EVA), Bio-Degradable, and Bio-Compostable compounds. This broad material compatibility allows manufacturers to work with both conventional and sustainable raw materials, supporting eco-friendly packaging initiatives.

Q3. Can the same machine produce both thin and thick films?

Yes. The 3 Layer Standard Co-Extrusion Blown Film Line is designed to produce films ranging from 20 to 150 microns in thickness from the same plant, with a layflat range of 500 to 1350 mm. This flexibility allows producers to switch between thin-gauge packaging films and heavier industrial films without requiring separate equipment, maximizing the return on a single machine investment.

Q4. What kind of after-sales support and maintenance services are available?

Comprehensive post-installation support is available including technical support with remote service capabilities, field service covering inspections, maintenance, repairs, modernization, die head cleaning, and retrofitting, along with access to original spare parts. A dedicated training academy is also available to ensure operator competency and long-term machine performance.
