High-Capacity Computerized PP Strapping Line

Product Overview: Fully Automated, High-Capacity PP/PET Strapping Production

The Computerized Plastic Packing PP Strapping Production Line is a fully automated system designed for high-capacity manufacturing of PP and PET packing straps. Controlled by a PLC (Programmable Logic Controller), it supports 1–4 straps produced simultaneously, with extrusion capacities ranging from 60kg/h to 300kg/h. This line accommodates 100% recycled PET flakes, virgin PP/PET materials, or mixed blends—balancing eco-friendliness and cost-effectiveness. It produces lightweight straps (as small as 12mm×0.6mm, 3.1g) with strong tensile strength and low skewness, suitable for both manual and automatic strapping machines. With a compact design and user-friendly interface, it is ideal for large-scale industrial strapping needs.

Core Features: PLC Automation & Superior Strap Quality

Fully Computerized Automation for High Efficiency

The PLC control system ensures stable, consistent operation—eliminating human error and reducing labor costs by up to 30%. The line produces 1–4 straps at once, with a maximum extrusion capacity of 300kg/h—meeting high-volume production demands (e.g., 2–4.5T daily output). A 5-roller haul-off unit and heating oven stretch machine optimize strap tensile strength (up to 1200N), ensuring durability for heavy-duty packaging.

Energy-Efficient & Material-Flexible Design

A uniquely designed oven and high-efficiency drive system minimize energy consumption (60–80kw/h power usage), while the ability to use 100% recycled PET flakes lowers raw material costs by 20–30%. This flexibility makes the line suitable for manufacturers seeking to reduce environmental impact without compromising product quality. The compact layout (22000mm×1500mm×5500mm) saves workshop space, enabling easy integration into existing facilities.

Superior Strap Quality for Reliable Packaging

The line ensures straps with uniform dimensions, low skewness (<0.5mm), and strong tensile strength—critical for secure packaging. Lightweight straps (12mm×0.6mm, 3.1g) are produced with high precision, suitable for delicate electronics or heavy cargo (e.g., 500kg+ pallets). An automatic winding unit ensures neat strap spooling, while an optional ink-jet printer adds product labels or batch numbers for traceability.

Applications: Industrial, Food & E-Commerce Packing

The PP/PET straps from this line are used in:

• Industrial Packaging: Securing heavy machinery parts, metal components, and auto parts during shipping—with wear resistance for long-distance transport.

• Food & Pharmaceutical: Packaging bulk food (e.g., flour, sugar) and pharmaceutical supplies—using non-toxic, food-grade materials that meet FDA standards.

• E-Commerce & Logistics: Strapping cartons, parcels, and pallets for last-mile delivery—resistant to moisture and tearing.

• Agricultural Products: Securing bags of seeds, fertilizers, and harvested crops—UV-resistant for outdoor storage (up to 2 years of weather resistance).

FAQs: Computerized PP Strapping Line Questions

Can the line produce both PP and PET straps?

Yes, it is compatible with both PP and PET materials, allowing manufacturers to switch between strap types (e.g., PP for light cargo, PET for heavy-duty use) based on market demand—no major equipment modifications needed.

What is the range of extrusion capacity for this line?

Extrusion capacities range from 60kg/h (small-scale) to 300kg/h (large-scale), with the option to adjust speed and output based on production needs (e.g., seasonal demand spikes).

Is the line suitable for producing lightweight straps for delicate products?

Yes, it produces lightweight straps as small as 12mm×0.6mm (3.1g) with low skewness—ideal for delicate items like electronics, glassware, or pharmaceutical packages (no damage to surfaces).

How does the PLC control system improve operation?

The PLC system automates the entire production process (feeding, extrusion, stretching, winding), reduces manual intervention, ensures consistent strap quality (no batch-to-batch variations), and simplifies operation—even for less experienced operators (intuitive touchscreen interface).
