As consumer demands for packaging rise, manufacturers face the imperative to provide film products that balance strength, barrier protection, cost-effectiveness, and sustainability. Multilayer blown film machines have emerged as a game-changing solution, enabling producers to manufacture high-performance, customized films tailored to specific applications.
These machines produce plastic film by co-extruding multiple layers of different polymers into a single, high-performance structure. Each layer serves a unique function, enhancing properties such as mechanical strength, clarity, sealability, and barrier performance.
Advantages of Multilayer Blown Film Machines
- Enhanced Barrier Protection: Effectively blocks oxygen, moisture, and contaminants, thereby preserving product quality.
- Superior Mechanical Strength: Stretching during the blown film process aligns polymer molecular chains, imparting greater toughness to the film.
- Cost-Effectiveness and Sustainability: Strategically combining recycled and virgin materials reduces costs while meeting environmental goals.
- Customizable Film Structures: Layer compositions can be precisely adjusted to meet specific application requirements.
- Stable, High-Quality Output: Automated control systems ensure consistent film thickness and reliable production performance.
With 30 years of industry experience, Xinye specializes in extrusion lines for single- and multilayer films (PE, PP, biodegradable materials, bubble film, stretch wrap, and shrink film); production lines for various plastic shopping bags, packaging bags, bubble bags, and kraft paper bubble mailers; as well as auxiliary equipment such as printing presses, recycling machines, crushers, and mixers. We provide you with high-quality multilayer blown film machines.
5-7-layer co-extrusion blown film machine
The 5-7-layer co-extrusion blown film machine is specialized equipment designed to produce packaging materials with gas or liquid barrier properties. Compatible raw materials include HDPE, MHDPE, LDPE, LLDPE, MLLDPE, PA, and EVOH resins. Its primary applications span heavy-duty packaging, premium food pouches, vacuum bags, and liquid packaging bags, delivering benefits such as aroma retention, freshness preservation, anti-corrosion properties, airtightness, and extended shelf life.
ABC Series 3 Layer Co-extrusion Blown Film Machine
The ABC blown film machine simultaneously extrudes three different types of plastic granules, combines them into a three-layer structure via a compounding unit, and then blows the film. Its unique advantage lies in producing film with high strength and toughness; it is widely used to manufacture high-quality plastic packaging products such as composite film substrates, liquid packaging films, shrink films, protective films, cable films, polymer adhesive films, and multifunctional industrial packaging films. The equipment is well-suited for high-precision, high-speed color printing, lamination, and coating processes.
ABA Series 3-Layer Co-extrusion Blown Film Machine
The ABA blown film machine is a standard choice for producing conventional flexible plastic packaging films. Compared to single-screw models, it enables higher utilization rates of recycled granules or fillers (such as calcium carbonate or sodium sulfate, with an addition ratio of 30%–80% in the B-layer), thereby reducing raw material costs. Furthermore, its “twin-screw plus 3-layer die” design results in lower equipment costs compared to “triple-screw plus 3-layer die” machines.
AB 2-Layer Blown Film Machine
This is a 2-layer co-extrusion blown film machine featuring a twin-screw and 2-layer die design, compatible with HDPE, LDPE, LLDPE, and biodegradable materials. It is primarily used to produce standard flexible packaging films or agricultural films. Compared to single-screw machines, it offers advantages such as higher output, superior film tensile strength, and the ability to produce films with different colors on each side.
