Triple Screw 3-Layer Bubble Wrap Film Machine

Each layer is separately controlled, can have different thickness, material formula and color.

Machine Overview

Here's how the process actually flows: the primary twin-screw extruder handles the raw material first, pushing it through and forming the base bubble film structure. From there, the secondary single-screw extruder takes over and laminates a third layer of PE film onto that bubble film, bonding the two together into the finished three-layer sheet. Compared to a version where the primary stage runs on a single screw, having a twin-screw system doing that first-stage work generally means steadier material mixing and more consistent output at the primary extrusion step — relevant for buyers running larger volumes or working with material blends that need more thorough mixing before they're formed into film.

One more thing worth knowing: on this machine, each layer can be separately controlled — meaning thickness, material formula, and color can all be set independently per layer rather than locked into one shared setting across the whole film. That gives a plant real flexibility to fine-tune the bubble layer differently from the outer laminated layer, whether that's for cost reasons, branding, or matching a specific end-use requirement.

Specific Applications
1. High-volume e-commerce and express packaging operations — plants running larger order volumes benefit from the steadier primary-stage output that a twin-screw system tends to provide compared to a single-screw primary setup
2. Furniture and large-item packaging — the three-layer structure suits heavier goods needing more cushioning depth than standard bubble wrap
3. Glassware and fragile goods protection — where consistent film quality from batch to batch matters for reliably protecting breakable items
4. Household appliance packaging — mid-size and larger appliances needing layered protection during transit
5. Multi-spec production for varied client requirements — since each layer's thickness, formula, and color can be set independently, this machine suits plants producing different film specifications for different buyers without needing separate equipment
6. Blended or mixed raw material processing — a twin-screw primary extruder generally handles material blending more thoroughly than a single-screw setup, which matters for plants working with mixed formulas or recycled content blends

Core Functions
1. Processes raw material through a twin-screw primary extruder, supporting more thorough material mixing at the first production stage
2. Laminates a third PE film layer onto the bubble film base through a secondary single-screw extruder
3. Produces a finished 3-layer film combining bubble cushioning with an added protective outer layer
4. Allows independent control of thickness, material formula, and color across each of the three layers
5. Forms, winds, and manages the full production sequence through connected forming, winding, and electronic control units
