Polyester Woven Strap Manufacturers, Factory

Polyester Woven Strap Manufacturing at Shanghai We Pack

Shanghai We Pack Co., Ltd. is the export-facing subsidiary of Shanghai Dreammao Packaging Technology Co., Ltd., an integrated packaging group working in cargo securing, transport protection and loading optimization. As a Polyester Woven Strap manufacturer in China, we produce high-tenacity woven polyester webbing and the tensioning hardware that turns it into a working lashing system for trucks, trailers, flat racks and containers.

The strap range is built for direct load restraint: flexible, energy-absorbing webbing that resists dynamic forces in transit and holds coils, pipes, timber, machinery and palletized freight against movement. It sits inside a wider securing portfolio — dunnage bags, paper corner protectors, slip sheets, stretch film and strapping tools — so a complete protection scheme can be sourced as one coordinated package instead of being assembled from separate vendors.

What the Polyester Woven Strap Range Covers

The range is organised around how the strap is tensioned and how it attaches, because those two decisions determine whether a lashing holds under braking, cornering and sea motion.

Woven polyester lashing strap — the core product: high-tenacity PET webbing for direct cargo securement, supplied as cut lengths or as finished assemblies.
Ratchet tie down assemblies — webbing with a ratchet buckle and hook or fitting ends for high-tension restraint on heavy loads.
Cam buckle and over-centre straps — lighter tensioning for repeated-use duties, pallet unitizing and lighter break-bulk loads.
End fittings — double-J hooks, flat hooks, wire hooks, claw hooks, D-rings, E-track fittings and sewn loops.
Wear protection — sleeves, reinforced eyes and edge guards for abrasive or sharp-edged cargo.
Custom lengths, widths, colours and printed branding under OEM/ODM programmes.

Where Polyester Woven Strap Fits in Cargo Securing

Polyester webbing is chosen where restraint has to stay tight over a long journey and absorb shock without going slack. Its low elongation under load keeps tension on the anchor point, while the woven structure spreads contact pressure across the cargo surface instead of concentrating it at a single point.

Cargo type	Securing duty	Typical configuration
Steel coils, wire rod	Direct lashing across the coil with high tension	Wide webbing, ratchet buckle, protective sleeve
Pipes, tubes, bundles	Bundle restraint plus cross lashing to anchor points	Medium-width webbing, ratchet or cam buckle
Timber and sawn wood	Stack restraint where low elongation matters	Wide webbing, ratchet buckle, hook ends
Machinery and heavy equipment	Direct lashing to deck rings and container anchor points	Heavy-duty webbing, high-tension ratchet
Palletized cartons and bagged goods	Pallet unitizing and container bracing	Narrow webbing, cam buckle, low-profile fittings
Container break-bulk	Cross lashing between opposing anchor points	Medium webbing, ratchet with hook ends

Specification Variables We Build Around

A lashing strap is only correct when the webbing, the hardware and the anchor point are rated as one system. These are the parameters we confirm before a quotation is issued.

Parameter	What it governs	Options we confirm with you
Webbing width	Contact area and how tension spreads over the load	Narrow to wide webbing matched to the load surface
Breaking strength and lashing capacity	Restraint force available against the cargo mass	Matched to the rated capacity of the securing point
Elongation at lashing capacity	Energy absorption and tension retention in transit	Low-elongation polyester webbing construction
Length and adjustment	Reach across the load and to the anchor point	Fixed length or adjustable, cut to order
Tensioning hardware	How much tension the operator can apply and hold	Ratchet buckle, cam buckle, over-centre lever
End fittings	Compatibility with the anchor point on the vehicle or container	Hooks, D-rings, E-track fittings, sewn loops
Edge and wear protection	Service life against abrasion and cut edges	Sleeves, reinforced eyes, edge guards
Marking and colour	Identification, fleet coding and inspection control	Printed branding, custom colour, label format

Material and Construction Considerations

Polyester webbing is the default choice for road and sea lashing because it combines high tensile strength with low stretch. Compared with polypropylene strap, polyester holds tension better under sustained load and resists creep; compared with nylon, it is less affected by moisture regain and better suited to long ocean legs. Weave density, yarn tenacity and the stitching pattern at the eye or buckle end all influence how the assembly behaves at working tension.

System note: the rated capacity of the weakest element — webbing, buckle, hook or anchor point — defines the usable lashing capacity. We size the strap so the webbing is not the limiting component in your securing scheme.

Hardware and Integration with the Rest of the Load

Strapping rarely works alone. On a typical container or flat-rack load, polyester webbing is combined with Ratchet Tie Down assemblies for the main restraint, Dunnage Bag void filling to stop longitudinal movement, and corner protectors to keep webbing off sharp edges. Because we manufacture across the Packing Strap family — PP, PET, composite and woven polyester — we can match the strap type to the load rather than force one material across every application.

Quality Assurance and Acceptance Testing

Web lashings for road transport are commonly specified against EN 12195-2, which defines lashing capacity, elongation and marking requirements. Our quality system runs a three-tier structure: an in-house laboratory, production-line testing equipment, and third-party verification through institutions such as SGS and TUV. Management is certified to ISO 9001, and the wider product portfolio is produced to AAR, SGS, TUV and EN 1492-1 requirements.

Customization and OEM/ODM Support

We develop strap to your drawing, sample or performance target. Custom work covers webbing width and length, lashing capacity, buckle and hook type, colour, printed logos and warning text, and retail or bulk packaging. Our engineering team also plans the securing solution around the cargo itself — load mass, loading method, anchor positions, budget and printing requirements — so the strap arrives as part of a workable scheme rather than an isolated component.

Information We Use to Configure Your Solution

A precise quotation needs the working conditions, not just a part number. These are the inputs our engineers work from.

Cargo type, unit mass, dimensions and centre of gravity.
Transport mode and route — road, rail, sea or multimodal, including expected regulatory framework.
Securing method: direct lashing, top-over lashing, cross lashing or bundle restraint.
Anchor point type, position and rated capacity on the vehicle or container.
Required lashing capacity and any elongation limit.
Webbing width, length and adjustment range.
Hardware preference and operator handling constraints.
Printing, colour coding, labelling and packaging format.
Order volume, delivery schedule and destination port.

Capacity, Order Scope and Delivery

Production runs across a 10,000 m² facility with 120 employees and nine production lines, supported by dedicated R&D, testing and quality control teams. Annual output exceeds 20,000 tons, which covers both trial quantities and repeat volume orders. Minimum order quantity starts at 100 pieces, so a first shipment can be validated on real loads before scaling. The plant sits close to Shanghai Port and Pudong International Airport, and we ship under EXW, FOB, CIF or DDP terms to customers across North America, South America, Europe, Asia and the Middle East.

Frequently Asked Questions

What is polyester woven strap used for?

It is used for direct cargo restraint — lashing coils, pipes, timber, machinery and palletized goods to trucks, trailers, flat racks and container anchor points. The woven polyester webbing absorbs dynamic loads during braking and cornering while keeping tension on the securing point.

How does polyester compare with PP or PET strap for lashing?

PP strap is cost-effective for light unitizing but stretches more under sustained load. PET strap is stiff and well suited to pallet and bundle strapping. Woven polyester webbing is the flexible option for lashing: it conforms to irregular cargo, spreads contact pressure and retains tension over long journeys.

Can you produce strap to our own specification and branding?

Yes. We work under OEM/ODM arrangements covering width, length, lashing capacity, buckle and hook type, colour, printed logos and warning text, and packaging format. Development can start from your drawing, a physical sample or a described working condition.

What test evidence is available for project acceptance?

Testing runs through our in-house laboratory and production-line equipment, with third-party verification available from institutions such as SGS and TUV. Batch records are retained for traceability, and test reports can be issued with the shipment for acceptance documentation.

What is the minimum order quantity and typical lead time?

Minimum order quantity starts at 100 pieces, which allows a trial order before volume commitment. Lead time depends on whether the strap is a standard configuration or a new custom build, and is confirmed with the quotation once width, capacity, hardware and printing are fixed.

Can you supply the strap together with dunnage bags and corner protectors?

Yes. We supply the full securing package — woven polyester strap, ratchet tie downs, dunnage bags, paper corner protectors, slip sheets, stretch film and strapping tools — so the load restraint, void filling and edge protection are specified together and arrive as one coordinated shipment.
