Pioneering sustainable plastic-alternative processing. This technology converts calcium carbonate and eco-friendly binders into heavy industrial packaging substrates.
Engineered for high elasticity index and minimal necking, this custom machinery improves film utilization and yield metrics for logistics warehouses.
Chittagong (Chattogram), the main seaport of Bangladesh, is the economic heartbeat of the nation, processing over 90% of its import and export transactions. Driven by rapid industrialization within the Chittagong Export Processing Zone (CEPZ) and the Karnaphuli Export Processing Zone (KEPZ), manufacturing entities are shifting toward automated shipping procedures. Stretch film plays a vital role in protecting and securing these export-bound goods.
The skyrocketing volume of Readymade Garments (RMG), jute products, leather, and seafood commodities demands high-durability wrapping. Traditional manual strapping is no longer viable for high-volume logistics. As global logistics networks enforce stricter requirements for load stability during transport, industrial entities in Chittagong are scaling up their packaging technology with state-of-the-art co-extrusion machinery.
Investing in local co-extrusion capacity rather than relying on imported films allows local packaging manufacturers to lower unit costs, optimize formulation parameters, and adapt quickly to the regional supply chain's dynamic needs.
A deep dive into the engineering parameters that drive yield, thickness control, and material cost savings.
Engineered flow paths in feedblocks allow for precise distribution of metallocene LLDPE (mLLDPE) across 5, 7, or 9 layers. This optimizes puncture resistance on outer layers while using cost-efficient core resins.
Online beta-ray or infrared sensors scan the film profile, communicating with thermal bolts on the T-die to maintain thickness tolerances within ±1.5%, minimizing weak spots that lead to film tear.
High-capacity internal cooling channels secure immediate cooling of the polymer melt. This locks in the amorphous structure, ensuring high transparency and excellent cling properties.

Integrates co-extrusion with inline laminating technology to output multi-layered composites in a single pass.
Aligning extrusion output specifications with regional industries for reliable performance.
Garments exported from CEPZ require reliable barrier protection against ocean humidity and moisture. High-cling, multi-layer stretch film keeps shipping cartons dry and securely palletized during ocean transit from the Port of Chittagong.
Heavy shipping volumes and multi-stage handling require film with high puncture resistance and stretch recovery. Metallocene-doped films resist tearing on sharp pallet edges during forklift transfers.
Chittagong's food processing sector relies on barrier-cast packaging to extend shelf life. Multi-layer co-extrusion lines help manage oxygen and moisture transmission rates effectively.
Key parameters for production managers and procurement officers when sourcing film machinery.
Energy is a major operating cost in plastic extrusion. High-efficiency extrusion systems utilize insulated ceramic heater bands, barrel cooling fans, and high-torque synchronous AC permanent magnet motors to lower power consumption per ton of throughput.
Processing recycled materials or mineral fillers requires wear-resistant screws. Bimetallic barrels and high-velocity oxygen fuel (HVOF) alloy coatings on screw flights help extend operational life.
Winding performance is critical for cast stretch films. Automatic winding systems with dual-directional turret designs and precise tension control algorithms help prevent telescoping and core collapse.
