Common Applications
1. Producing general-purpose HDPE film for packaging, wrapping, and bag stock
2. Manufacturing HDPE+LLDPE blended film where flexibility and seal strength both matter
3. Supplying film for converters producing mid-to-large size bags and liners
4. Running continuous daily production for buyers moving beyond entry-level extrusion equipment
5. Producing film intended for further processing, such as printing or bag conversion, where consistent gauge matters

Basic Function

Running two φ60mm screws in parallel lets this 1400 Type HDPE LLDPE Film Extrusion Machine process HDPE alone or blend it with LLDPE, giving buyers flexibility to switch resin strategy between production runs without swapping equipment.

The Φ250mm rotating die head is built to distribute film thickness evenly as the material is blown — a detail that becomes more important at this machine's 1300mm width, where uneven cooling or extrusion pressure would otherwise show up as thick or thin bands across the roll.

A double-lip wind ring (1000mm diameter, labyrinth entrance) manages cooling, fed by a 5.5kw Delta inverter blower with frequency control, letting operators tune airflow to whichever resin mix is running.

On the winding side, the 1400 Type HDPE LLDPE Film Extrusion Machine uses a double-breaking, double-receiving system with four Φ50mm air-shaft rollers, plus two dedicated edge-trim winding units and a heated breaking knife — together, these keep roll changes and scrap handling from interrupting the main run.

Main motor power is rated at 18.5kw per extruder, with screw speed adjustable up to 100r/min, giving operators room to match line speed to material and thickness requirements.

Investment Value

Starting an in-house private label film supply — packaging businesses currently outsourcing HDPE or blended film production use this machine to bring that capability in-house, gaining direct control over resin choice and film specification instead of depending on a third-party supplier.

Supplying wholesale orders at consistent volume — distributors filling recurring orders for HDPE and HDPE+LLDPE film rely on the 120-160kg/hr output range to meet standing commitments without production gaps.

Lowering material cost while keeping film performance — blending HDPE with LLDPE, rather than using a single premium resin throughout, gives buyers a way to manage cost per kilogram without sacrificing the flexibility or seal quality the end application requires.

Problems It Solves

Committing to a single resin type across an entire film locks buyers into one set of trade-offs — either strength or flexibility, rarely both. Running HDPE and LLDPE together on this machine removes that trade-off, since each resin can be positioned where its properties matter most.

Wider film widths tend to expose thickness inconsistency more visibly, especially toward the edges of the roll. The rotating die head on the 1400 Type HDPE LLDPE Film Extrusion Machine is built specifically to manage that variation across the full 1300mm width.

Manual handling of roll changes and edge trim slows down continuous production, particularly as daily output volume increases. The double-breaking, double-receiving winder and dedicated edge-trim units on this machine are designed to keep that handling from becoming a bottleneck.
