Product Introduction
Plastic Blown Film Machine – Industrial Extrusion Solutions for Flexible Packaging
Our plastic blown film machine changes LDPE and LLDPE tars into high-quality straightforward movies with exactness and proficiency. Sponsored by over 30 a long time of fabricating ability, Rizhao Jinlida conveys strong machines highlighting 28:1–30:1 screw L/D proportions, 4–6 arrange temperature control (150–180℃), and yield capacities extending from 20 to 200 kg/h. With screw distances across from 45mm to 90mm and greatest lay-flat widths up to 2000mm, you get steady film thickness (15–100μm) and predominant load-bearing performance—ideal for creating shopping packs, nourishment bundling, and mechanical movies that bolster loads from 8 to 50kg.
What Makes Our Plastic Blown Film Machine Different?
You require gear that runs easily and conveys comes about day after day. Our machines are built for solidness and ease of operation.
Precise Temperature Management
The 4–6 warming zones keep handling temperatures between 150–180℃. This guarantees uniform softening and anticipates fabric corruption. You get movies with reliable clarity and strength.
Energy-Efficient Motors
Motor control scales with screw size—from 7.5 kW (45mm) to 75 kW (85mm+). This plan decreases power costs whereas keeping up tall throughput. Your generation remains beneficial indeed amid long runs.
Flexible Film Specifications
Produce movies from 15 to 100 microns thick. Most extreme lay-flat widths extend from 600mm (SJ-45) to 2000mm (SJ-75). Whether you're making level sacks or wide bundling rolls, the machine adjusts to your needs.
Stable Bubble Control
Single or twofold discuss ring alternatives keep up a blow-up proportion of 1:2.5 to 1:4. This keeps the bubble unfaltering and the film gage uniform over the web. You diminish squander and progress wrapped up item quality.

Frequently Asked Questions
Q: Why is film thickness uneven over the web?
A: Uneven gage as a rule comes about from a misaligned kick the bucket hole or conflicting wind current from the discuss ring. High-quality machines utilize programmed gage control frameworks to adjust these issues in genuine time, guaranteeing uniform thickness.
Q: Can this machine handle reused plastic?
A: Yes. When prepared with a specialized screw plan and ceaseless screen changer, the machine handles reused substance successfully. The filtration framework evacuates debasements without ending generation, keeping up film quality.
Q: What causes 'fisheyes' or gels in the film?
A: These abandons regularly stem from destitute dissolve homogenization or corrupted fabric. Expanding the L/D proportion or utilizing a bimetallic screw makes strides blending and diminishes defilement, coming about in cleaner films.
Q: How does Inside Bubble Cooling (IBC) progress output?
A: IBC cools the bubble from the interior, permitting speedier line speeds. This can boost yield by 20–30% whereas upgrading film straightforwardness and lessening vitality utilization per kilogram produced.
Q: What is the normal life expectancy of the expulsion screw?
A: With standard polyethylene materials, a bimetallic screw keeps going 3–5 a long time. If you handle grating added substances or high-filler compounds, specialized solidifying medications amplify screw life and keep up reliable compression proportions.
