Working Process

The ABC three-layer die head is the core of this machine — three extrusion stages feed into one film structure, giving buyers control over which resin goes where instead of committing an entire roll to a single material.

Main motor power comes from two units rated at 15kw and 18.5kw, driving the extrusion process across both screw stages, with output running in a range that suits continuous mid-volume production rather than occasional test batches.

Cooling and film stability come from a double wind ring system (1000mm diameter, labyrinth inlet), which manages airflow as the layered film forms — a detail that matters more with multi-layer extrusion, where uneven cooling can affect how well the layers bond.

On the haul-off side, six Φ70mm traction pinch rollers pull the film through consistently, while the winding section uses four Φ50mm air-shaft rollers to manage roll changes without stopping the main production line.

The overall frame runs 3400mm by 6000mm by 7200mm, giving a sense of the floor space and installation planning this kind of three-layer extrusion line requires compared to smaller single-screw machines.

Typical Uses

1. Producing multi-layer HDPE and HDPE+LLDPE packaging film for general industrial and retail use
2. Manufacturing film where cost-driven middle layers reduce material spend without weakening outer-layer performance
3. Running continuous production for converters needing dependable output beyond small-batch extrusion
4. Producing film for applications where combining resin types in one pass matters more than single-material uniformity

Investment Value

Building an in-house private label film supply — packaging businesses that currently source multi-layer film from outside suppliers use a machine like the 1100 Type Three-Layer ABC Blown Film Machine to bring that production step under their own control, setting resin combinations and film specs to match their own product line.

Meeting recurring wholesale film demand — distributors supplying converters that need multi-layer HDPE film in volume rely on continuous ABC extrusion output to keep pace with standing orders, rather than running smaller single-layer batches to fill the same demand.

Managing material cost across a layered structure — the practical reason most buyers choose three-layer ABC extrusion over single-layer equipment is cost control: put a premium resin only where the film actually needs it, and fill the rest with a more economical blend.

FAQ

Q1: What does the ABC configuration mean for this machine?
It refers to three separate extrusion stages feeding one film structure, allowing different resins or blends in each layer instead of a single uniform material.

Q2: Why choose three-layer extrusion over single-layer?
It allows cost-efficient resin in the middle layer while keeping stronger material on the outer layers, lowering material cost without sacrificing key film properties.

Q3: Can the resin layer ratio be adjusted for specific applications?
Yes, OEM/ODM configuration is available to adjust layer ratios, screw setup, and winding specifications based on the buyer's target film use.
