Fully Biodegradable Blown Film Printing Machine

Specific Applications
1. Producing biodegradable shopping bags and carrier bags printed with store branding or logos
2. Making compostable food packaging film for bakeries, produce packaging, and takeaway supply chains
3. Running printed mailer bags and courier bags made from PLA+PBAT biodegradable film
4. Producing standard PE or PO printed film for buyers who also need conventional plastic packaging alongside biodegradable lines
5. Supplying printed roll stock to downstream bag-making machines for further conversion
6. Manufacturing agricultural or retail packaging film where both film extrusion and printed branding are needed on one production line

Core Functions

The Fully Biodegradable Blown Film Printing Machine combines two production stages that are usually handled by separate equipment.

Film blowing stage — the extrusion screw melts and processes PO, PE, or PLA+PBAT resin into blown film, with die diameter and blown film width varying by model (600mm for CX-P50, up to 1000mm for CX-P60).

In-line printing stage — printed graphics are applied directly onto the freshly blown film, with printing width scaled to match each model's film output (560mm to 960mm depending on model).

Adjustable screw L/D ratio — each model offers a 28, 30, or 32:1 ratio option, giving buyers some control over how the resin is processed based on material type and output needs.

Overprint precision control — horizontal and vertical registration is held to a tight tolerance (0.2mm horizontal, 0.2+0.2mm vertical) across all three models, which keeps printed graphics aligned as the film moves through the line.

Solutions for Challenges

Converters looking into biodegradable film equipment tend to run into a few recurring issues, and this machine addresses them directly.

Running biodegradable and conventional film on separate lines adds cost and complexity. The Fully Biodegradable Blown Film Printing Machine processes PO, PE, and PLA+PBAT materials on the same equipment, so buyers aren't forced to maintain two different production setups.

Coordinating film extrusion and printing as separate steps slows down production and adds handling risk, especially with thinner biodegradable film that can be harder to manage. This machine keeps both stages in one continuous line, reducing the number of times the film needs to be handled before it's finished.

Choosing the right machine size for actual output needs is a common challenge. With three model options — CX-P50, CX-P55, and CX-P60 — buyers can select based on film width and extrusion volume requirements rather than being locked into one fixed configuration.

FAQ

Q1: What materials can this machine process?
The Fully Biodegradable Blown Film Printing Machine runs PO, PE, and PLA+PBAT biodegradable resin blends.

Q2: What's the difference between the three models?
CX-P50, CX-P55, and CX-P60 differ mainly in screw diameter, extrusion volume, and maximum film/printing width — larger models handle wider film and higher output.

Q3: Can the machine be configured for a specific film width?
Yes, OEM/ODM configuration is available — screw diameter, die size, and printing width can be adjusted based on production requirements.
