We provide a complete Packing Strap system for every bundling and securing challenge. Our portfolio includes cost-effective PP straps, high-tensile PET (steel alternative) straps, rugged Composite Straps for heavy industry, flexible Lashing Straps, and ready-to-use Ratchet Tie-Down systems. This range ensures optimal performance, from simple carton closure to securing critical loads on trucks and in containers, backed by verifiable strength test data.
Shanghai We Pack Co., Ltd. is a Packing Strap manufacturer in China, producing PP, PET, composite and polyester woven strapping alongside ratchet tie-down lashing systems for cargo securing and transport protection. Founded in 2019 as a subsidiary of Shanghai Dreammao Packaging Technology Co., Ltd., we run a 10,000 m² facility with 9 production lines and dedicated R&D, testing and quality control teams. Strapping is supplied as a working system — strap, buckles, tensioning tools and loading input — so the grade, joint and tensioning method match the cargo instead of the nearest stock size.
Five strap families cover the distance from carton closure to container restraint. Widths, thicknesses and break strengths are produced to order, and the grade is selected against the load path, the transport mode and the tensioning equipment already installed on the packing line.
| Strap Family | Base Material | Duty Level | Typical Applications | Closing & Tensioning |
|---|---|---|---|---|
| PP Packing Strap | Polypropylene | Light to medium | Carton bundling, parcel and light pallet unitizing, warehouse and dispatch packing | Heat seal, friction weld, plastic or metal buckle; manual or electric tensioner |
| PET Packing Strap | Polyester (PET) | Medium to heavy | Palletized brick, tile, profiles, baling, steel-strap replacement | Seals, friction weld, PET/steel strap buckles |
| Composite Strap | Polyester fibre composite | Heavy, high retained tension | Steel coils, pipe bundles, timber, construction materials, machinery, outdoor storage | Buckles, wire buckles, tensioners |
| Polyester Woven Strap | Woven polyester | Heavy lashing | Container and flatbed load restraint, bundled heavy goods | Ratchet assemblies, buckles, hooks |
| Ratchet Tie Down | Polyester webbing with ratchet assembly | Load restraint | Truck, flatbed, container and rail securing of machinery and heavy units | Ratchet handle, J-hook, double J-hook, flat hook |
PP strapping carries the light end of the range: cartons, parcels and light palletized goods where cost per metre and clean handling matter more than retained tension. PET Packing Strap takes over where loads are heavier and relaxation has to stay low, and it is the practical replacement for steel strap on palletized brick, tile, profiles and baling work. Our Composite Strap Factory output serves the heavy end — coils, pipe bundles, timber and machinery — where abrasion, UV exposure and sustained tension decide the outcome.
Strap performance is decided by a small set of variables, and we fix them in writing before a run starts. The same specification set is used for PP, PET, composite and woven strap.
Strap performs only when the tensioning and closing hardware matches it. We supply the connectors and tools that complete the system: fiber buckles, PET/steel strap buckles, manual fiber strap tensioners, electric and pneumatic strapping machines, automatic strapping machines, carton sealers and PP/PET strap dispensers. Consumables are matched to the machine in service, so coil dimensions, strap stiffness and surface friction suit the feed and tensioning path rather than fighting it.
On automated lines the strap grade, coil format and dispenser configuration are agreed together with the machine interface, and sample coils are run before a production order is released.
Production runs across 9 lines in a 10,000 m² plant, with raw material intake, extrusion or weaving, forming, cutting, welding and packing handled as separate controlled stages. In-house laboratory testing is backed by third-party verification through SGS and TUV, and the management system is certified to ISO 9001. Products are supplied against AAR, SGS, TUV and other international transport test standards, with test reports issued for the delivered batch.
Custom work is the normal case rather than the exception. We produce to drawings or physical samples across size, load capacity, material and printing, and the engineering team reviews the application before a specification is frozen. Minimum order quantity starts at 100 pieces, which keeps trial and qualification orders practical while larger programmes run on the same lines.
A usable proposal needs the working point, not just a strap size. The matrix below shows what we ask for and how each item changes the configuration.
| Project Input | How It Shapes the Configuration |
|---|---|
| Cargo type and unit weight | Sets the strap family and the break strength band |
| Load pattern and transport mode | Determines whether the strap unitizes, restrains or does both, and the margin applied |
| Target width and thickness | Fixed against the load face, the buckle or seal, and the tensioning tool |
| Break strength and elongation | Chosen for retained tension across long sea or road legs |
| Joint or closure method | Heat seal, friction weld, seal, buckle or ratchet, with joint efficiency checked |
| Tensioning equipment and line speed | Sets coil format, strap stiffness and surface for reliable feed |
| Printing and branding | Private label, embossing or printed marking on the strap |
| Coil core, length and weight | Matched to dispensers, strapping machines and manual handling limits |
| Destination and compliance | Determines test documentation and any regional transport requirements |
| Volume and delivery schedule | Drives run planning across the 9 production lines |
Strap ships on cores in coils, in cartons or on pallets, with the pack format set to suit the dispenser, warehouse handling and container fill. The plant sits close to Shanghai Port and Pudong International Airport, and we work on EXW, FOB, CIF and DDP terms with regular supply to North America, South America, Europe, Asia and the Middle East. Consumables are kept compatible with the major strapping equipment brands, so a change of strap source does not force a change of machine.
PP is the cost-efficient choice for cartons, light parcels and light palletized goods, where clean handling and low cost per metre matter most. PET carries higher break strength with low elongation and holds tension on heavy palletized loads, which is why it replaces steel strap on brick, tile, profiles and baling work. We match the grade to unit weight, load pattern and the tensioning equipment in use, then confirm it with sample coils.
Yes. OEM and ODM production covers size, load capacity, material and printing, including private-label marking on the strap surface. Minimum order quantity starts at 100 pieces, and drawings or physical samples are both workable starting points.
Composite strap is engineered for abrasion and UV resistance with minimal stretch, which suits coils, pipes, timber and construction materials stored or transported outdoors. Polyester woven strap and ratchet tie-down assemblies cover restraint duties in containers, on flatbeds and in rail transport, where the strap is part of the load-securing plan rather than simple unitizing.
Raw material, in-process and finished-goods checks run in our own laboratory, and third-party verification is available through SGS and TUV. Break strength, elongation and joint performance are tested against the agreed specification, and test reports accompany the delivered batch. Retained samples and batch records support repeat orders and later qualification work.
We supply the full closing and tensioning set: fiber buckles, PET/steel strap buckles, manual fiber strap tensioners, electric and pneumatic strapping machines, automatic strapping machines, carton sealers and PP/PET strap dispensers. Consumables are matched to the machine's feed and tensioning path, and sample coils are run before a production order is released.
Cargo type and unit weight, load pattern and transport mode, target strap width and break strength, joint or buckle method, coil core and length, printing requirements, destination and expected volume. With those details we return a specification, pack format and price, and where the load case is unusual we plan the securing method together with the strapping configuration.
