Core Functions

The AB two-layer co-extrusion setup is the core of this machine — two separate extruders (φ56mm and φ55mm screws) feed a swing-plate distributor that combines the layers at a 40/60 ratio, giving finished film the layered structure that makes stretch film cling and hold under tension.

Automatic roll changing runs through a PLC-controlled system paired with a tile-type air expanding shaft, so the winding side of the line can swap to a fresh roll without stopping production — a detail that directly supports the machine's 24-hour output target.

The sub-machine uses a "swing" winding method combined with a high-speed structure, while a matte roller on the fourth winding position and a φ420mm cooling/winding roller diameter are built into the line to manage film handling at speed.

Edge trim from the production process is automatically routed to a recycling machine, cutting down on manual waste handling during continuous runs.

Heating across the barrel uses aluminium-plated heating rings, which the manufacturer notes are intended to reduce energy use compared to standard heating ring designs, and the main drive motors (11kw and 22kw) run through inverter-controlled speed regulation.

Specific Applications
1. Producing LLDPE pallet stretch wrap for logistics and warehouse packaging
2. Manufacturing cling film for food wrapping and food service packaging
3. Supplying stretch film rolls to distributors serving shipping and freight industries
4. Running continuous production for converters supplying wholesale packaging material buyers
5. Manufacturing film at commercial scale for buyers replacing manual or lower-volume wrapping film production

Procurement Motivations

Starting a private label stretch film brand — packaging suppliers who want to move from reselling stretch film to producing it under their own label use a line like the HD-800 High Speed Film Wrapping Machine to control film specifications and supply consistency directly.

Meeting ongoing wholesale film demand — distributors supplying stretch film to logistics, warehousing, or food packaging customers need dependable daily output, and the roughly 2.5-3 tonne per day capacity on this machine supports that kind of standing order volume.

Controlling material cost through in-house co-extrusion — producing AB two-layer film in-house, rather than buying finished stretch film from a third party, gives converters more control over the LLDPE resin ratio and material cost per roll.

FAQ

Q1: What kind of film does this machine produce?
PE stretch film, including pallet winding film and cling film, made from LLDPE resin.

Q2: How does the two-layer structure benefit the finished film?
The AB co-extrusion structure, split at a 40/60 ratio, is what gives stretch film its combination of cling and tear resistance.

Q3: Is roll changing automatic?
Yes, a PLC-controlled system with an air expanding shaft handles roll changes without stopping the line.
