3 Layer High Output Co-Extrusion Blown Film Line

High-Performance Three-Layer Co-Extrusion for Superior Film Quality

The 3 Layer High Output Co-Extrusion Blown Film Line is a high-performance OBC-type co-extrusion blown film plant engineered for manufacturers who demand precision, versatility, and consistent film quality across a broad range of applications. Built on a robust three-layer co-extrusion architecturewith a simple yet efficient mechanical design, this machine delivers high-gloss, uniform films with minimal gauge variation even at elevated production speeds. Its straightforward operation and compact build make it equally suitable for established film producers and growing manufacturers looking to optimise output without added complexity.

With a production output ranging from 240 to 310 Kg/Hr and screw configurations at a 30:1 L/D ratio, the line achieves excellent homogeneous mixing and melting of polymers across all three layers. The layflat range of1200 to 2100 mm combined with a thickness capability of 20 to 200 micronsallows producers to manufacture both thin-gauge and heavy-duty films from the same plant, maximising equipment utilisation. The advanced screw and die design prevents melt degradation over extended production runs, preserving the best optical properties of the film throughout. The system also enables effortless bubble control and easy layflat size adjustments, minimising changeover downtime between production runs. Compatible polymers include LLDPE, LDPE, HM-HDPE, HDPE, EVA, and metallocene resins, offering broad material flexibility for diverse packaging requirements.

This blown film line caters to a wide spectrum of industrial, consumer, and agricultural applications. On the industrial side, it efficiently produces lamination film, surface protection film, tarpaulin film, shrink hood film, stretch hood film, and tyre release film. For consumer packaging, it supports food packaging film, LD shrink film, stretch film, milk pouches, water packaging film, courier bags, and atta packaging. It also serves agricultural filmapplications including mulch film and agroshed net film, reflecting its cross-industry versatility.

FAQ's

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

The machine delivers an output range of 240 to 310 Kg/Hr depending on the selected model and extruder size. Entry-level configurations such as the SE3HR 1700-55/65/55 achieve 240–250 Kg/Hr, while higher-end models like the SE3HR 2200-55/75/55 reach up to 240–310 Kg/Hr, making the line well-suited for small-to-medium as well as high-volume film production facilities.

Q2. What polymers and materials are compatible with this blown film line?

The machine is compatible with a wide range of polymers including LLDPE, LDPE, HM-HDPE, HDPE, EVA, and metallocene resins. This broad material compatibility allows manufacturers to produce films with varied mechanical and optical properties from soft food-grade packaging films to tough industrial films on a single machine.

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

Yes. The 3 Layer HHR Blown Film Line is designed to produce films ranging from 20 to 200 microns in thickness, with a layflat range of 1200 to 2100 mm all from the same plant. This flexibility allows producers to switch between thin-gauge consumer packaging films and heavy-duty industrial films without requiring separate equipment.

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, modernisation, 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.
