Product Description:
The ABA three-layer co-extrusion T-shirt bag blown film machine is a plastic film production equipment utilizing A+B+A three-layer composite co-extrusion technology. The equipment achieves three-layer feeding through two extruders — the outer layers (Layer A) are fed by one main extruder, and the middle layer (Layer B) is fed by the other extruder. The inner and outer layers use the same material, forming a symmetrical three-layer structure.
The machine adopts high-quality alloy steel screws and barrels, processed through nitriding treatment and precision machining, offering optimal hardness and corrosion resistance. The die head is made of 40CR material, meticulously processed through multiple treatments, with the spiral body machined on imported four-axis linkage machining centers, ensuring die precision and uniform material distribution in each spiral channel.
The ABA three-layer co-extrusion blown film machine is suitable for blowing various plastic films including HDPE (High-Density Polyethylene), LDPE (Low-Density Polyethylene), and LLDPE (Linear Low-Density Polyethylene). The equipment can be equipped with an advanced continuous rotating die head, ensuring smooth film surface and excellent uniformity, meeting the quality requirements of subsequent processing equipment such as printing machines and bag-making machines.
TECHNICAL PARAMETERS：
The core function of the ABA T-shirt bag blown film machine is to produce high-quality, low-cost plastic films through three-layer co-extrusion technology, primarily used for manufacturing various plastic packaging bags.
Core value in three aspects:
1. Significant Cost Reduction
The biggest advantage of the ABA structure is that the middle layer (Layer B) can incorporate up to 50%~75% calcium carbonate filler or recycled material. The outer layers (Layer A) use virgin material, accounting for only a small percentage of the total film composition. Since the outer layers are made of virgin material, the film surface remains aesthetically pleasing and glossy even when recycled material or filler is added to the middle layer.
2. Enhanced Film Physical Strength
Through multi-layer co-extrusion technology, ABA film exhibits superior toughness and higher tear resistance compared to monolayer film at the same thickness. The three-layer structure improves the film's physical strength by approximately 30%.
3. Reduced Equipment Configuration & Energy Efficiency
The ABA structure achieves three-layer co-extrusion with just two extruders, eliminating the need for one extruder compared to ABC three-layer configurations, thereby reducing equipment investment costs and operational energy consumption.
