The Jwell PET strapping line’s standard configuration extrudes 4 strands simultaneously (一出四) from a single T-die — four parallel straps traveling through a shared or individually-lane stretching oven, embossed, and wound on four independent winding stations. This 4-strand architecture delivers approximately 450 kg/h total line output (300-500 kg/h range), with each strand producing 75-125 kg/h depending on strap width and thickness.
The 4-strand configuration provides three operational advantages over running the same total output on multiple single-strand lines:
Capital efficiency: One extruder, one control system, one dryer, one operator, and one factory footprint serve all four strands. The capital cost per ton of annual PET strap capacity is approximately 30-50% lower than four single-strand lines.
Labor efficiency: One operator manages the entire 4-strand line versus four operators for four single-strand lines. In markets where skilled extrusion operators command premium wages, this labor savings is a decisive competitive advantage.
Energy efficiency: One large single-screw extruder (with proportionally larger motor) operates at a higher efficiency point than four small extruders. The barrel heat loss — the dominant thermal inefficiency — is proportional to machine surface area, which is lower for one large extruder than four small ones.
The 4-strand die is engineered with identical flow path length and pressure drop for each cavity, ensuring uniform strap dimensions across all four strands — critical when all strands go to the same customer or specification.

PET’s most critical processing requirement is not temperature or pressure — it is moisture. PET is hygroscopic: it absorbs 0.3-0.5% moisture from ambient air within hours. When PET containing this moisture is heated to extrusion temperature (260-280°C), the water molecules attack the ester linkages in the polymer backbone through a chemical reaction called hydrolysis. The result:
– Intrinsic viscosity (IV) drops from the feedstock value (typically 0.70-0.80 dL/g for bottle-grade PET) to 0.60 dL/g or below
– Tensile strength of the finished strap drops proportionally — a 0.10 dL/g IV loss can reduce strap strength by 15-25%
– Melt strength drops, causing strap breakage during the hot-stretching operation
– Visible defects appear — surface bubbles, internal voids, silver streaks — that cause strap rejection
Jwell integrates a two-stage drying system upstream of the extruder:
Stage 1 — Crystallization (for amorphous PET bottle flakes): Amorphous PET flakes soften and stick together at 70-80°C in the dryer hopper, forming a solid mass that blocks material flow. The crystallizer heats the flakes to 140-160°C under agitation, inducing crystallization before they enter the main dryer. Crystallized flakes do not stick together at dryer temperature.
Stage 2 — Dehumidifying drying: A desiccant dryer with honeycomb rotor achieves -40°C dew point in the drying air. PET flakes are held at 160-170°C for 4-6 hours, reducing moisture content to below 50 ppm — the industry-standard threshold for high-quality PET strap extrusion. A heated, insulated conveying system between dryer and extruder hopper prevents moisture re-absorption.
For customers running virgin PET resin (pre-crystallized as supplied), only Stage 2 drying is required. For the more common case of recycled bottle flakes, both stages are essential.

The extruded PET strip — as it exits the water bath cooling tank — has the random-coil molecular structure of amorphous PET with tensile strength of only 40-60 MPa. To achieve the 300-800 kg per strap tensile strength that competes with steel strapping, the strip must be hot-stretched — heated to a temperature between the glass transition (approximately 75°C for PET) and the cold crystallization temperature (approximately 130°C), then drawn to 4-7 times its original length.
This hot-stretching process transforms the molecular structure through three simultaneous mechanisms:
Molecular orientation: The polymer chains, mobile at the stretching temperature, align along the strap axis under the drawing tension. This alignment converts the isotropic (equal in all directions) mechanical properties into anisotropic properties — high strength and stiffness along the strap axis, where it is needed.
Strain-induced crystallization: Chain alignment brings PET molecules close enough to crystallize — forming oriented crystallites that act as physical crosslinks, locking in the orientation and preventing molecular relaxation. The degree of crystallinity increases from near-zero (amorphous quenched strip) to 25-40% (oriented strap), depending on stretch ratio and temperature.
Density increase: Oriented and crystallized PET has higher density (approximately 1.37-1.39 g/cm³ versus 1.33 g/cm³ for amorphous PET), reflecting the tighter molecular packing.
The Jwell stretching oven uses multi-zone hot-air circulation with independent zone temperature controllers. The stretch ratio is set through the speed differential between the first and second haul-off — both driven by ABB inverter-controlled motors — and displayed on the Siemens HMI. Typical stretch ratios: 4:1 for general-purpose PET strap, 5:1-6:1 for high-tensile grades, up to 7:1 for maximum-strength applications.

Recycled PET bottle flakes present four extrusion challenges that virgin PET resin does not:
Residual moisture: Even after drying, recycled flakes may contain trace moisture in the core of thick flake particles. The extruder’s vented barrel design (atmospheric vent in the decompression zone) provides a secondary moisture removal safeguard.
Variable IV (intrinsic viscosity): Recycled PET from mixed bottle sources has variable IV (0.70-0.80 dL/g range). The extruder must deliver consistent melt quality despite feedstock variability.
Abrasive contaminants: Paper labels, aluminum caps, and dirt not fully removed in the washing process are abrasive. The screw and barrel require wear-resistant metallurgy.
Low bulk density: Washed, dried PET flakes have bulk density of 0.30-0.40 g/cm³ — requiring a larger-diameter feed section for adequate intake.
Jwell’s PET strapping extruder addresses all four challenges:
– 30:1 L/D ratio: Longer than the standard 28:1 for PP, providing the additional residence time needed for complete melting and homogenization of variable-IV recycled feedstock
– Vented barrel: Atmospheric vent removes residual moisture as a safeguard
– Bi-metallic screw and barrel (optional upgrade): CPM-10V or equivalent wear-resistant alloy for extended service life on recycled feedstock
– Large-diameter feed section: Proportionally sized to handle low-bulk-density flake feeding
– Hydraulic double-station screen changer: Filter mesh change without line stoppage — a critical uptime feature for 24/7 recycled-PET production

The steel and metal industry was the earliest and remains the largest adopter of PET strapping as a steel strap replacement. PET strap bundles steel coils (hot-rolled, cold-rolled, galvanized), steel pipes, metal profiles, aluminum ingots, and copper cathodes — applications where steel strapping was the historical standard but where PET now dominates for four reasons:
Rust elimination: Steel strap rusts during outdoor coil storage, causing rust staining that damages the top layer of expensive finished steel products — a defect that steel mills deduct from the coil price. PET strap is completely rust-proof.
Worker safety: Steel strap cut with hand tools creates razor-sharp edges that cause the most common injury in steel coil warehouses. PET strap has no sharp edges and is cut with standard scissors.
Weight reduction: PET strap at 1/6 the weight of steel reduces shipping weight (and freight cost) and eliminates the disposal cost of used steel strapping.
Tension retention: PET strap’s elasticity allows it to absorb the thermal expansion and contraction of steel coils during temperature changes, maintaining bundle integrity where rigid steel strap would loosen.
The 25-32 mm wide PET strap sizes — standard specifications for steel coil bundling — are produced on the Jwell 4-strand line at 300-500 kg/h.

Lumber mills, engineered wood product manufacturers, brick and tile producers, and building materials distributors use PET strap to bundle products that are stored outdoors for months before delivery to construction sites. Key requirements:
Outdoor durability: PET strap with UV stabilizer (added as masterbatch at the extruder) retains tensile strength and color during 6-12 months of outdoor exposure. This is essential for lumber bundles stored in open yards.
High strength: 25-32 mm wide PET strap delivers 500-800 kg tensile strength to secure heavy lumber bundles, brick packs (1-2 tons), and ceramic tile pallets through long-distance transport.
No staining: Unlike steel strap (rust) and some PP strap formulations (plasticizer migration), PET strap does not leave marks or stains on the wood surface — important for appearance-grade lumber.
Recyclable: Used PET strap from the construction site is collected and recycled, closing the material loop from bottle flake feedstock to strap to recycled flake for new strap.
PET strapping band — often called plastic-steel strap — delivers comparable tensile strength (300-800 kg per strap) to steel strapping at approximately 1/6 the weight. Beyond the weight advantage, PET strap is completely rust-proof (eliminating rust stains on finished goods), has no sharp edges (eliminating worker injuries from cut steel band), retains tension better during long transport cycles due to elasticity, and is 100% recyclable. For steel mills, lumber mills, brick manufacturers, and export craters, the total cost of ownership calculation — accounting for material cost, worker safety, product damage from rust, and disposal — increasingly favors PET over steel.
The 4-strand configuration extrudes four PET straps simultaneously from a single T-die, each traveling through the stretching oven and wound on its own independent winding station. This configuration delivers approximately 450 kg/h total output from one extruder, one control system, and one operator — maximizing per-ton capital, labor, and energy efficiency. The standard PET strap market demands high volume (steel mills, cotton gins consuming tons of strap per day), and the 4-strand line meets that demand at the lowest per-ton cost.
PET strapping is primarily produced from recycled post-consumer PET bottle flakes — washed, sorted by color, and processed into clean flake. The recycled feedstock reduces raw material cost by 30-50% versus virgin PET resin and supports circular-economy procurement. Virgin PET resin is also usable for premium applications requiring maximum optical clarity or the most consistent tensile strength. The feedstock must pass through a crystallizer (for amorphous bottle flakes) and dehumidifying dryer to achieve <50 ppm moisture before extrusion.
PET is hygroscopic — it absorbs moisture from air. Without drying, the moisture in PET flakes (typically 0.3-0.5%) causes hydrolysis during extrusion at 260-280°C: water molecules break the ester linkages in the PET polymer chain, reducing molecular weight (intrinsic viscosity drops from 0.70-0.80 dL/g to below 0.60), reducing tensile strength by 15-25%, reducing melt strength (causing strap breakage during stretching), and producing visible bubbles/streaks on the strap surface. Jwell’s integrated dryer system reduces moisture to <50 ppm, the industry-standard target for defect-free PET strap.
Three factors determine PET strap tensile strength: (1) Feedstock IV — higher intrinsic viscosity PET produces stronger strap (bottle-grade 0.70-0.80 dL/g is standard); (2) Stretch ratio — higher draw ratios (4:1 to 7:1) produce higher molecular orientation and therefore higher strength, up to the practical limit where further stretching causes strand breakage; (3) Strap dimensions — wider and thicker straps have proportionally higher absolute tensile strength. The Jwell line’s independent haul-off speed control and multi-zone stretching oven allow the operator to dial in the exact stretch ratio for the target strength specification.
