PET Strapping Products by Grade, Surface and Color
Choose PET strap by the tool or machine it will run on, then by surface and color. Every type below comes in the full width range on our spec sheet.
Hand Grade PET Strapping for Manual & Battery Tools
For manual tensioners, battery-powered and pneumatic tools. Hand rolls are usually about 20 kg on a 406 mm (16 in) core, easy for one operator to load into a dispenser.
Machine Grade PET Strapping for Automatic Strapping Lines
For semi-automatic and fully automatic strapping machines, and for plants that automate end-of-line packing. Machine grade strap is made to a higher break strength and tighter width and thickness tolerances so it feeds and welds consistently, and it comes in larger coils, up to 1,000 kg.
AAR PET Strapping (Type IV) for Rail Loads
Our Type IV PET strap, smooth and embossed with friction welds, is verified under the AAR Open Top Loading Rules in three sizes: 5/8 × 0.035 in, 5/8 × 0.040 in and 3/4 × 0.040 in.
Embossed & Smooth PET Strap
Embossed strap has a textured surface that grips in seals and tools; smooth strap is common on friction-weld heads. Match the surface to your sealing method.
Green PET Strapping, Black Polyester Strapping, White & Custom Colors
Green PET strapping is the usual industrial color. Black polyester strapping and white strap are standard options, and we can match a custom color for brand or grade identification. Flame-retardant PET strap is available on request, sourced through JUHONG.
PET Baling Strap for Cotton Bales, Cut to Length
Cut-length PET strap for cotton and fiber bale presses, closed with a metal buckle or a heat-welded joint. Packed about 16,000 pieces to a 1.9 × 0.98 m pallet.
Flame-Retardant PET Strap, V-0 Rated
Fire-resistant PET strap for lithium battery modules and other loads that must not feed a fire. Sourced through JUHONG and shipped with your standard PET strapping.
What Is PET Strapping? Polyester Strapping Material Explained
PET strapping is a plastic strapping band extruded from polyethylene terephthalate, the polymer usually called polyester. The melted resin is formed into a flat band and stretched along its length, which lines up the polymer chains and gives the strap its strength. You will also see it sold as PET strap, polyester strapping or polyester banding. Packers use it to bundle products and secure pallet loads. It is a different material from polypropylene (PP) strap, which stretches more and holds less tension, and a different product from strapping tape.
How PET Strapping Holds a Load: Tension, Elongation & Recovery
When PET strap is tensioned it stretches a little and stores that energy. If the load settles or shifts during handling, the strap recovers and keeps pressure on the bundle instead of going slack. That tension retention is why PET is used on palletized loads that compress during transportation, such as bricks, timber, cotton bales and paper rolls. PET does not rust, so it will not stain products stored outdoors. It is durable, light and safe to cut, which makes it the usual alternative to traditional steel strap in pallet packaging and logistics.
Where PET Strapping Is Not the Right Choice
PET is a strong plastic, but some loads still need steel. Use steel strapping when the product is hot, when sharp edges would cut the strap and edge protectors cannot be fitted, or when a carrier or loading rule names steel. PET packaging strap is also not a lifting or lashing device. For those loads, see our steel strapping.
PET Strapping Sizes & Break Strength Chart
JUHONG polyester PET strapping comes from 3/8 to 1-1/4 in (9 to 32 mm) wide and 0.5 to 1.4 mm thick. Break strength rises with width and thickness, so each width covers a range. Many buyers order by lbs break strength, so the chart lists pounds too; a 1/2 inch polyester strap covers our 10 to 13 mm widths. Send your current size or required break strength and we will match it.

PET Strap Quality Grades & Breaking Tenacity
| Quality grade | Breaking tenacitykg/mm² | Breaking tenacityMPa (N/mm²) |
|---|---|---|
| L | ≥ 35 | ≥ 343 |
| M | ≥ 40 | ≥ 392 |
| H | ≥ 45 | ≥ 441 |
| S | ≥ 50 | ≥ 490 |
Breaking tenacity is break strength divided by the strap cross-section, so it compares strap quality across sizes. A higher grade gives more break strength from the same width and thickness.
Hand Grade vs Machine Grade PET Strapping
Machine grade PET strap is held to a higher break strength and tighter width and thickness tolerances than hand grade, because an automatic head feeds, tensions and welds strap continuously and small variations cause misfeeds or weak joints. Hand grade suits manual and battery tools and lighter daily volumes. Both are made in the same widths; the difference is the tolerance, the strength target and the coil size.
How to Read PET Strap Break Strength
Break strength is the force that snaps one strap in a tensile test. It is not the weight a strap can hold. The joint, whether a seal or a weld, is usually weaker than the strap itself, and several straps share the load on a pallet. Choose a size with a margin above the force you expect in handling and transport, and confirm it on your own load before a volume order.
Flame-Retardant PET Strap for Battery Modules
Fire-resistant PET strap is made for lithium battery and battery module strapping, where the strap has to hold the cells tight without feeding a fire. It reaches a V-0 rating in vertical burning tests and HB in horizontal tests, and it insulates the module. This flame-retardant PET strap is sourced through JUHONG, so you can add it to the same order as your standard PET strapping.
| Property | Value |
|---|---|
| Flame rating | V-0 vertical · HB horizontal |
| Tensile fracture stress | ≥ 450 MPa |
| Elongation at break | ≤ 15% |
| Joint strength | ≥ 360 MPa |
| Insulation | > 6,000 MΩ at DC 1,000 V |
| Common sizes | 14 × 1.0 · 15 × 1.3 · 16 × 0.8 · 19 × 1.0 · 19 × 1.27 mm |
PET Strapping Rolls: Cores, Coil Weights & Export Packaging
PET strapping rolls are wound on a 406 mm (16 in) paper core, the standard size for dispensers and strapping machines. Core width and coil weight change with the format. Hand rolls are light enough to lift by hand; machine coils go on a pallet with a forklift. We can now wind coils up to 1,000 kg for high-volume automatic lines, which means fewer coil changes per shift.
10 kg Rolls
Core 406 × 76 mm (16 × 3 in). Light hand rolls for manual and battery tools, packed 48 or 52 rolls per pallet.
20 kg Rolls
Core 406 × 150 mm (16 × 6 in), roll about 560 mm (22 in) across. The usual roll for hand tools and many strapping machines; see the size drawing and pallet loads below.
70 kg Machine Coils
Core 406 × 190 mm (16 × 7.5 in), coil about 750 mm (29.5 in) across, for semi-automatic and automatic strapping machines.
330 kg Jumbo Coils
Core 406 × 305 mm (16 × 12 in), coil about 900 mm (35.4 in) across, for high-volume automatic lines. Shown here in black machine grade strap.
1,000 kg Jumbo Coils
Our largest coils, wound to order for automatic lines that want the fewest coil changes per shift. Tell us your machine and we match the core and coil width.
Cut Strap for Cotton Bales
Cut lengths for cotton and fiber bale presses, bundled and wrapped on a long pallet. Pallet and container loads are listed below.
Standard 20 kg Roll: Size and Pallet Loads
Standard 20 kg rolls are packed 28, 52 or 56 to a pallet, so they store neatly and move by forklift. If your warehouse or racking needs a different load, we change the roll count, pallet pattern and wrapping, and can pack under your brand.
| Rolls per pallet | Stacks × rolls | Palletmm | Load height | Net weight |
|---|---|---|---|---|
| 28 | 4 × 7 | 1,160 × 1,160 | 1,250 mm (49.2 in) | 560 kg |
| 52 | 4 × 13 | 1,160 × 1,160 | 2,190 mm (85.8 in) | 1,040 kg |
| 56 | 4 × 14 | 1,160 × 1,160 | 2,340 mm (92.1 in) | 1,120 kg |
Net weight is 20 kg per roll; pallet and wrapping are extra.
Container Loading: 70 kg Coils, 330 kg Coils and Cut Strap
Typical net loads per container. The exact count depends on pallet height, pattern and the container weight limit, so we confirm the loading plan with your order.
Container Load: 70 kg Coils
Container Load: 330 kg Coils
Container Load: Cut Strap
Which Coil Weight Should You Order?
Match the coil to the way you strap. Operators using hand or battery tools usually take 10 or 20 kg rolls, which fit a standard dispenser and are easy to change. Strapping machines run 20 kg rolls or 70 kg coils, and high-volume automatic lines use 330 kg coils or heavier, up to 1,000 kg, to cut downtime for coil changes. Whatever the weight, the core inside diameter and core width must fit your dispenser or machine, so send its model with the inquiry.
How to Choose PET Strapping for Your Load
Begin with the load. Note the pallet or bundle weight, whether it will settle or swell, how far it travels and how it is handled. Then pick the tool or machine, and choose width, thickness and coil format to match it. If you already use PET strap, send a photo of the coil label and we will match the size, strength and surface.
PET vs PP vs Steel Strapping
| PET strapping | PP strapping | Steel strapping | |
|---|---|---|---|
| Best for | Medium to heavy pallets and bundles that settle | Light boxes, cartons and small bundles | Very heavy, hot or sharp-edged loads |
| Retained tension | High; recovers when the load settles | Lower; stretches and relaxes | High, but no recovery once the load settles |
| Rust | Does not rust | Does not rust | Needs a coating against rust |
| Handling | Light, safe to cut | Light | Heavy, sharp edges when cut |
PP strapping is available on request for light boxes.
Steel strapping
Little stretch: the braking shock goes straight into the strap and seal, and the load shifts.
PET strapping
The strap stretches, absorbs the shock and springs back, so the load stays tight.
PP strapping
Stretches the most but holds little force: the strap relaxes and the load stays shifted.
Illustrative curves, not test data.
Why PET Strap Holds Loads Through Bumps and Braking
When a truck brakes or a pallet is reloaded, the load surges against the strap. Steel strap is very strong but stretches very little, so the shock goes straight into the strap and the seal. PET strap stretches further before it breaks, then recovers, so it absorbs the shock and keeps the load tight. That margin between the applied tension and the break is the shock reserve. PP stretches the most but holds the least force and relaxes over time, so keep it for light boxes and cartons.
Smooth or Embossed PET Strap?
Embossed PET strap has a raised pattern that helps it grip in metal seals and some tools. Smooth strap is often used on friction-weld heads and automatic machines. Both come in every width; the right surface depends on your sealing method, so tell us the tool or machine model.
Joining Methods: Metal Seals, Friction Weld & Heat Seal
PET strap is joined three ways: with a metal seal crimped by a sealer, by friction welding in a battery, pneumatic or automatic tool, or by heat sealing with a hot knife on an automatic machine. Friction and heat welds need no seals.
Cotton Bale Strapping: Buckle or Heat-Welded Joints
Cotton gins and fiber plants strap pressed bales with cut-length PET baling strap. The strap is closed in one of two ways. A metal strapping buckle is threaded by hand and needs no power tool. A heat-welded joint is made by the bale press or a welding tool and leaves no metal on the bale. Tell us which your press uses and we will supply bale strapping cut to length, with buckles if you need them.
PET Strapping Applications
Buyers use JUHONG PET strapping for industrial bundling of cotton and fiber bales, red bricks and aerated concrete blocks, non-ferrous ingots, metal and wire coils, pipe, solar panels, flat glass, bottle pallets, paper rolls and timber. PET strap serves industries such as brick, timber, textile, paper and metals, where loads need steady tension without rust or metal edges. Compressible bales and bricks benefit from PET’s recovery, timber and paper from its clean surface, and ingots and pipe from its strength. For the heaviest steel coils, hot products and sharp-edged sections, use steel strapping.
Cotton Bales and Textile Fiber
Pressed cotton and fiber bales push back against the strap after compression. PET strap holds that force without breaking or relaxing, and we supply both coils and cut lengths for bale presses.
Bricks, Blocks and Construction Materials
Brick and block pallets sit outdoors and settle as they are moved. PET strap does not rust or stain the product, and its recovery keeps the stack tight through loading and delivery.
Metals: Non-Ferrous Ingots, Coils and Pipe
Aluminum and other non-ferrous ingot bundles, metal coils and pipe bundles are heavy but often not sharp-edged. Wider, thicker heavy-duty PET strap, such as 19, 25 or 32 mm, gives these heavy loads high strength without the rust marks of uncoated steel.
Paper Rolls, Timber and Glass
These loads need a clean strap that will not mark or scratch the surface. Use edge protectors on corners and choose embossed or smooth strap to suit your sealing method.
Tools, Seals & Strapping Machines for PET Strap
PET strap is closed one of two ways: with a metal seal and a manual tensioner and sealer, or with a friction-weld tool that needs no seal. Our strap also runs on battery tools and automatic strapping machines from makers such as Signode, Fromm, Orgapack, Cyklop and ITATOOLS. Send the tool or machine model and we will confirm the width, thickness and surface that fit it, or order strap, seals and a tool together as one strapping kit.
Manual Tensioner, Sealer & Metal Seals
No power or air needed. The tensioner pulls the strap tight and the sealer crimps a metal seal. Suits embossed strap, low daily volumes and work away from the line.
Pneumatic Friction-Weld Tool (XQD-19)
Runs on shop air. One button tensions the strap, friction-welds the joint and cuts it, so no seals are used. Suits higher volumes and heavier loads.
Serrated Seals for PET Strap
Open serrated strapping seals for polyester strapping: the teeth grip the strap so the joint does not slip. Sized to your strap width.
PET Strapping Tools
Manual tensioners and sealers, battery and pneumatic friction-weld tools.
Send your load, daily volume and current tool model; we will match strap, seals and tool.
PET Strapping Production & Quality Control
Our PET strap manufacturing line dries the resin, extrudes it into a flat band, stretches it twice, embosses or smooths the surface, heat-sets it and winds it onto the core. Checks run from the resin to the finished coil, because break strength depends on both the resin and the stretching process. See how we inspect every batch on our quality control page.
Material feeding · Pre-crystallization drying · Melt extrusion
Primary stretching · Secondary stretching
Embossing or smooth finish · Heat setting · Cooling
Winding on 406 mm cores · Packing to order
Break Strength & Elongation Tests
Break strength and elongation are checked on finished strap. SGS tested our 16 × 0.8 mm PET strap to GB/T 22344-2018, and the report is on our Downloads page.
AAR and ISO Certificates for PET Strap
Our PET strap is AAR-verified (AAR-124) for rail loads and made under ISO 9001, ISO 14001 and ISO 45001. All certificates and compliance documents are on our certificates page.
Is PET Strapping Recyclable? The Circular Process
Yes. PET strapping is made from polyester and can be recycled at the end of its life. Used strap goes back into new strap through the six steps below. Tell us if your program needs recycled content and we will discuss what we can document.
How PET Strap Is Recycled in Six Steps
01 Used Strap
Used PET strap is collected for recycling instead of being thrown away.
02 Flakes
The strap is cleaned and shredded into flakes.
03 High-IV Granules
The flakes are upgraded into high-IV granules, which restores the strength the strap needs.
04 Extrusion
The granules are melted, extruded and stretched into new strap.
05 New PET Strap
The strap is wound into coils and checked for break strength.
06 Back in Use
It goes back onto pallets and bundles, ready to be recycled again.
Our PET Strap Recycling Network Around Changzhou
Our plant is in Changzhou, Jiangsu, in the Yangtze River Delta. We work with 18+ partner recycling stations within about 100 km of the plant, which recycle 24,000 t of plastic a year and cut CO₂ emissions by about 34,200 t a year, next to the 12,000 t of PET strap our line makes each year.

PET Strapping FAQ
Short answers to the questions distributors and packing managers ask us about PET strap.
Are you a PET strapping manufacturer or a trading company?
We are a PET strapping manufacturer. We extrude PET strap on our own line in Changzhou, China, with an annual capacity of 12,000 t, and the same plant makes steel strapping, strapping seals and stretch film.
Do you supply PET strapping wholesale to distributors?
Yes. We are a wholesale PET strapping supplier to distributors and importers, including those who stock green polyester strapping for resale. Orders start at 1 ton, standard-size samples are free, and we can pack under your brand.
What is PET strapping?
PET strapping is a plastic packaging strap made from polyethylene terephthalate (polyester). It is extruded and stretched into a strong band used to bundle products and secure pallet loads.
Is PET strap the same as polyester strapping?
Yes. PET strap, polyester strapping, polyester banding and PET packing strapping are names for the same product. The size, strength and surface still have to be specified.
Is PET strapping recyclable?
Yes. PET strap is made from polyester and can be recycled. Used strap is cleaned and shredded into flakes, upgraded into high-IV granules and extruded into new strap. Ask us if your program needs recycled content documented.
Do you supply PET strap for cotton bales?
Yes. We supply cut-length PET baling strap for cotton and fiber bales, packed about 16,000 pieces to a pallet, for buckle or heat-welded joints. Tell us your bale press and the cut length you need.
Which is stronger, PET or PP strapping?
PET. At the same size, PET strap has a higher break strength and holds tension better as the load settles. PP suits light boxes; PET suits medium to heavy pallets and bundles.
Can PET strapping replace steel strapping?
On many pallet and bundle loads, yes, where rust, weight or cutting safety are a concern. Keep steel for hot products, sharp edges and loads where a rule or carrier specifies steel.
What is the difference between hand grade and machine grade PET strapping?
Machine grade strap has a higher break strength, tighter width and thickness tolerances and larger coils, so it feeds and welds reliably in automatic machines. Hand grade, usually in 10 or 20 kg rolls, suits manual, battery and pneumatic tools.
Does PET strapping rust, and how UV resistant is it outdoors?
PET strap does not rust and resists moisture and normal weather, so it is used on bricks, timber and other loads stored in open yards. For storage, keep unused coils in their wrapping and out of direct sun. If loads will stand in direct sun for months, ask us about UV resistance for your grade.
Do you supply flame-retardant PET strap?
Yes. Flame-retardant (fire-resistant) PET strap with a V-0 vertical burning rating is sourced through JUHONG, mainly for lithium battery modules. Tell us the strap size and the standard your project names, and we will send the data sheet.
What sizes of PET strapping do you make?
