Sandwich Packaging Belt Production Line

Sandwich Packaging Belt Production Line

The Sandwich Packaging Belt Production Line is a highly efficient and automated system designed to produce packaging belts for various applications. This production line is widely used in industries that require robust and reliable packaging materials, such as logistics, manufacturing, and retail.

Composition of the Production Line

The production line consists of several key components, each playing a crucial role in the manufacturing process. These components include:

- Extruder: This is the main machine responsible for melting and extruding the polypropylene (PP) material into a belt shape.

- Cooling Water Tank: After extrusion, the belt passes through a cooling water tank to solidify and stabilize its shape.

- Heating Oven: The belt is then heated in an oven to enhance its properties and prepare it for further processing.

- Traction Machine: This machine pulls the belt through the production line, ensuring consistent movement.

- Shaping Water Tank: Another water tank is used to shape and cool the belt further.

- Winding Machine: Finally, the finished belt is wound onto reels for storage and transportation.

Working Principle

The production process begins with polypropylene particles being fed into the extruder. These particles are heated and melted, then extruded into a belt shape. The belt is cooled in the water tank, heated in the oven, and stretched to enhance its strength and flexibility. The belt can also be printed, embossed, or dyed during this process to meet specific requirements. The final product is a high-quality packaging belt that is moisture-resistant, corrosion-resistant, and has excellent tensile strength.

Technical Parameters

- Width: The production line can produce belts with widths ranging from 6mm to 32mm and 50mm to 100mm.

- Linear Speed: The maximum linear speed of the production line is 120 meters per minute.

- Energy Consumption: The total energy consumption of the production line is 40kW.

- Output: The production capacity is between 100kg/h and 200kg/h.

Performance Characteristics

- Moisture Resistance: The packaging belt is not afraid of moisture and has low water absorption, ensuring it remains strong even when wet.

- High Strength: The belt has a small elongation rate and can maintain its tensile force for an extended period, making it suitable for long-distance transportation.

- Flexibility: Unlike steel belts, the sandwich packaging belt is flexible and safe to handle, reducing the risk of injury.

Sandwich Co-Extrusion PET/PP Packaging Belt Production Lines

A high-performance Sandwich Packaging Belt Production Line is specialized plastic extrusion machinery. It is engineered for manufacturing heavy-duty PET and PP strapping bands. Unlike industrial conveyor belts, this advanced equipment utilizes multi-layer co-extrusion technology. It produces high-tensile plastic straps used in global packaging and logistics. As a professional manufacturer, Qingdao Zhongrui Plastic Machinery Co., Ltd. delivers robust and efficient extrusion solutions. Our highly automated systems are designed to meet the rigorous demands of modern packaging applications.

How Sandwich (A-B-A Layer) Co-Extrusion Technology Works

In plastic extrusion, the term "sandwich" refers to an innovative multi-layer co-extrusion process. It is typically structured as an A-B-A layer configuration. This technology allows manufacturers to strategically distribute raw materials. It optimizes both production cost and strap performance. By utilizing a high precision sandwich strapping line, facilities can process up to 100% recycled materials. You can use recycled PET flakes or PP granules in the thick core layer (Layer B). Meanwhile, virgin or premium-grade materials are extruded on the outer surfaces (Layers A). This A-B-A sandwich structure provides several critical manufacturing advantages:

• Cost Efficiency: It drastically reduces raw material expenses by maximizing recycled plastics in the core layer.
• Premium Finish: The virgin outer layers ensure exceptional surface smoothness, a glossy appearance, and excellent weldability.
• Structural Integrity: The strap maintains high tensile strength, low elongation, and split resistance for heavy-duty use.

Featured Sandwich Packaging Belt Production Lines

Our comprehensive range of packaging straps production lines is engineered to maximize factory output. They easily accommodate various raw material inputs. Whether processing polypropylene (PP) or polyethylene terephthalate (PET), our machinery ensures consistent dimensional stability. It also guarantees superior mechanical properties across every production run.

High-Capacity PP Packaging Belt One Output Two Production Line

This high-capacity system represents a major leap in extrusion efficiency. It utilizes an advanced "One Output Two" die head technology. The machine extrudes two separate PP strapping bands simultaneously from a single system. This dual-strap extrusion method effectively doubles daily production output. It also optimizes valuable factory floor space and improves overall energy efficiency.

PET Sandwich Packaging Belt Extrusion Line

Designed specifically for heavy-duty packaging applications, this extrusion line excels in processing 100% recycled bottle flakes. The system features robust dehumidifying, drying, and crystallization units. These components prevent material degradation during the melting process. The resulting PET straps offer superior tensile strength and low elongation. They serve as an ideal, cost-effective replacement for traditional steel strapping.
