32mm PET Strapping Band 15360N Polyester Packing Strap For Oversized Cargo

I am the production engineer at our PET strapping plant in Hubei, China, and this page is written by me rather than by a copywriter. The product you are reading about is the 32mm × 1.2mm jumbo PET strapping band we call the 3212 — a PET Plastic Steel Strap (PET Polyester Strapping) developed for oversized and super-heavy cargo. Below I describe plainly what it is, how we make it, how we test it, and how to choose the right strap for your load.

Conventional 19mm strapping was never designed to hold a five-ton machine base through a six-week sea voyage. The 3212 solves that with an ultra-wide bearing surface and a thickened wall, spreading load across far more contact area than a standard band. It is corrosion resistant, lighter than steel, and safe to open at the destination warehouse.

Above: the 32mm × 1.2mm jumbo PET strap as it leaves our line. The broad flat body and the embossed surface you can see here are exactly what keep a heavy load from shifting in transit.

The table below lists every parameter a packaging engineer needs. The 15,360 N figure is not an abstract number: it is the breaking strength measured on a full-section 32mm × 1.2mm specimen on our tensile bench and verified under our SGS physical performance test procedure. Breaking strength scales directly with width and thickness, so a narrower or thinner band carries proportionally less — the two values must always be read together.

For reference, the same line produces related models so you can match the band to the load: 25mm × 1.2mm at 12,000 N, 32mm × 1.0mm at 12,800 N, and 19mm × 1.2mm at 9,120 N.

The band is made in a continuous seven-step flow, and every step is open to you during a factory audit:

1. Extrusion — dried virgin PET resin is melted and extruded into a uniform wide sheet.
2. Stretching — the sheet is drawn under heat to orient the polymer chains, which is what creates tensile strength.
3. Embossing — the surface is embossed for grip, or calendered smooth to your order.
4. Cooling — controlled cooling locks in the elasticity so elongation stays stable.
5. Roll Winding — the band is slit to width and wound onto a 250mm core.
6. Quality Inspection — each roll passes the checks described in the next section.
7. Packaging — rolls are wrapped and palletised for export.

Quality is a set of measurements, not a claim. Before any roll is packed we check:

• Width — measured on every production run against the ordered tolerance.
• Thickness — checked to confirm the band is not under-gauge at any point along the roll.
• Tensile / Breaking Strength — pulled on our calibrated bench; anything below the stated value is held back, not shipped.
• Surface Quality — inspected for cracks, burrs and uneven embossing.
• Roll Packaging — weight, wind and outer wrapping are verified before palletising.

Our strapping is SGS certified, and each batch carries an SGS physical performance test report. We welcome third-party inspection — rather than asking you to take my word for it, I would rather you tested a sample yourself.

I recommend the 3212 for five groups of cargo, and here is why it fits each one:

• Steel products — high tensile strength holds heavy steel bundles where a narrow strap would snap, and it will not scratch or corrode like metal banding.
• Timber and wood — the wide bearing surface grips rough-sawn bundles without crushing the edges.
• Construction materials — corrosion resistance keeps the strap intact outdoors and in humid port conditions.
• Machinery — oversized machine bases and frames stay stable because load is spread across the full 32mm width.
• Heavy and oversized cargo — for anything a 19mm strap cannot pin down, the 3212 gives lightweight handling with steel-grade holding power.

When you specify a strap, six factors decide the result. Send me these and I will size it for you:

• Cargo weight — total load and stacking determine the strength class you need.
• Strap width — wider bands spread pressure and protect soft or sharp-edged loads.
• Strap thickness — thicker walls raise breaking strength for super-heavy goods.
• Required breaking strength — match it to load weight with a sensible safety margin.
• Packaging method — whether you band by hand or with a semi-automatic or automatic machine.
• Tensioning equipment — the strap must be compatible with your existing tensioner and sealer.

• Manufacturing focus — a plant dedicated to PET strapping, with our own extrusion and stretching lines.
• Production capability — 2,000 tons per month, with the 3212 grade held in stock for fast shipment.
• Quality control — batch-by-batch testing backed by SGS physical performance reports.
• Export-ready packing — waterproof wrapping and export-grade pallets prepared for sea, land and air freight.
• Customization capability — width, thickness, color, surface, roll length, roll weight and logo printing.

Q1: What is the breaking strength? A: The 3212 is rated at 15,360 N, measured on a full-section 32mm × 1.2mm specimen; narrower or thinner bands carry proportionally less.

Q2: Can PET strap replace steel strap? A: Yes. It delivers comparable holding power while being corrosion resistant, lighter and safer to handle and to open.

Q3: What cargo is it suitable for? A: Oversized and heavy loads — steel, timber, construction materials, machinery and super-heavy palletised goods.

Q4: Can width and thickness be customized? A: Yes. Widths from 16mm to 32mm and thicknesses from 0.6mm to 1.2mm are produced on the same line.

Q5: What information do you need for a quotation? A: Your cargo weight, required width and thickness, packaging method, destination port and order quantity.

Q6: What is the MOQ and lead time? A: Our minimum order is 5 tons; stock items ship in about 7 days and made-to-order lots take roughly 7–15 days after deposit.

Tell me your load weight, crate type and destination port, and I will recommend the model, thickness and roll length that fit your packaging line — backed by a free load test and sample before you commit.
