Plastic Strapping Explained: PP, Polyester and Paper Alternatives for Buyers

Plastic strapping is a packaging material used to bundle, restrain, and palletize products across logistics, manufacturing, and export industries. The two most common types are polypropylene (PP) strapping and polyester (PET) strapping, often called PP strap, pp band, pet banding, or polyester strapping. A third option, paper strapping, is gaining attention as a plastic-free alternative for light and medium loads.

For buyers searching for “plastic strapping manufacturers,” the early-stage task is not simply to pick a supplier. It is to understand how materials, specifications, manufacturing processes, and verification standards differ. This article explains the differences between PP strap, PET strap, and paper strapping, summarises the global market context, and outlines the steps buyers take to evaluate plastic strapping manufacturers.

PET plastic strapping rolls are used for heavy-load and export packaging.

Why Strapping Material Selection Is Harder Than It Looks

Selecting the correct plastic strapping seems simple, but the consequences of a wrong choice appear only at the worst moment: a pallet that loosens in transit, a strap that snaps during lifting, or a machine line that stops because of poor straightness. Several factors make material selection difficult for buyers.

First, terminology varies. The same product can be called pp strapping, polypropylene band, pp strap roll, polypropylene hand strapping, or plastic band, and specifications are expressed in different units across regions. Second, load requirements differ widely. A lightweight e-commerce carton, a chemical fiber bale, a brick pallet, and a steel coil each need different tensile strength, elongation, and surface characteristics. Third, manufacturers operate with different raw material quality, process control, and test regimes, so two straps with the same nominal dimensions can perform very differently on a line.

In practice, buying decisions should be based on four pillars: load security, machine compatibility, compliance, and sustainability. Load security depends on break force and elongation. Machine compatibility depends on straightness, roll winding, and heat seal behavior. Compliance depends on certifications and test reports. Sustainability depends on material recyclability, recycled content, and options such as paper strapping for plastic-free packaging.

Plastic Strapping Market Context

The strapping materials market is large and still growing. According to Grand View Research, the global packaging strapping materials market was valued at USD 9.8 billion in 2025 and is projected to reach USD 15.7 billion by 2033. Polypropylene strapping held the largest share, approximately 33.9%, driven by its cost effectiveness in logistics and e-commerce. The global PET strapping market is expected to grow at a CAGR of 5.8% from 2024 to 2033, reaching USD 1.44 billion. Recycled PET (rPET) already accounted for about 34% of global strapping production in 2024, reflecting the industry’s shift toward sustainability.

China is a major supplier of plastic materials globally. UN Comtrade data cited by OEC shows China’s total exports of plastics (HS 39) reached USD 141.16 billion in 2024, with Mainland China accounting for roughly 32% of global plastic exports. For industrial strapping, international standards such as ASTM D3950-23 and EN 13394:2001 define dimensions and physical properties for non-metallic strapping. In China, PET strapping and PP strapping are commonly tested against GB/T 22344-2018 and QB/T 3811-1999, respectively.

Plastic Strapping Materials: PP, PET and Paper

PP Strapping (Polypropylene Strapping)

PP strapping is made from high-quality polypropylene resin. It is the most widely used plastic strapping for cartons, light industrial goods, food and beverage bundles, and logistics operations. Jushuo Packaging produces machine grade and hand grade PP strapping in widths from 5 to 19 mm and thicknesses from 0.35 to 0.90 mm, with break force from 45 to 270 kg depending on specification. Machine grade products, such as the 12mm Machine Grade PP Strapping, offer 110 to 180 kg break force, roll lengths from 2000 to 3000 m, and core sizes of 200 mm, 228 mm, or 406 mm. Straightness deflection is ≤5 mm/m, which helps prevent jams in automatic strapping machines.

PP strap is available in smooth or embossed surfaces, in clear, white, black, green, and custom colors, and with custom printing of logos or safety messages. Hand grade polypropylene strapping, used for manual bundling, typically has a softer texture and is designed for easy tensioning and knotting. The 12mm hand grade PP strap from Jushuo has a break force of 220 to 270 kg, suitable for retail, warehouse, and courier operations. PP strapping products comply with QB/T 3811-1999, are manufactured under ISO 9001 and ISO 14001 systems, and can be RoHS compliant. SGS test reports are available upon request.

For buyers, the main advantage of PP strap is cost efficiency and handling convenience. It is also recyclable. The main limitation is elongation: break elongation for standard machine grade PP strap is below 20%, which is acceptable for cartons but less suitable for heavy loads that demand very low stretch.

PET Strapping (Polyester Strapping)

PET strapping, also called polyester strapping or pet strapping roll, is manufactured from high-strength PET resin. It is designed to replace steel strapping in heavy-duty applications while eliminating rust, sharp edges, and dangerous spring-back. Jushuo’s PET strapping ranges from 9 to 25 mm in width and 0.40 to 1.27 mm in thickness. Break force spans from 160 to 1360 kg: a 19×1.0 mm PET strap reaches about 860 kg, while a 25×1.25 mm strap can reach 1360 kg. Elongation is ultra-low, at ≤10% for standard PET and ≤6% for reinforced series.

The manufacturing process matters. Jushuo uses solid-state polymerization (SSP) equipment to raise the intrinsic viscosity of PET resin, followed by biaxial or uniaxial stretching and hot-air annealing. This process helps achieve tensile strength of 380 to 500 MPa, consistent straightness with deflection ≤5 mm/m, and heat seal weld compatibility. Machine grade PET strap is designed for fully automatic high-speed strapping, while hand grade PET strap has optimized flexibility for manual tools and semi-automatic machines. Both smooth and embossed finishes are available, and custom specifications, colors, and printed logos can be produced.

PET strapping is 100% recyclable and can be manufactured with recycled PET content. It weighs about one-sixth as much as steel, which reduces freight cost and worker fatigue. Compared with steel strapping of equivalent strength, PET strap costs approximately 35-40% less in material cost. PET products from Jushuo comply with GB/T 22344-2018 and are ISO 9001 and ISO 14001 certified. SGS test reports for PET strap show a breaking force of 9.98 kN and elongation of 10% for a 12 mm specification.

Eco-Friendly Strapping: Paper and rPET

eco-friendly strapping is a response to plastic packaging regulations, plastic taxes, and consumer demand for recyclable materials. Jushuo’s range includes Eco Friendly PET Strapping, made from recyclable PET resin, and Eco Friendly PP Strapping, which is 100% recyclable. For plastic-free packaging, Jushuo also produces Paper Strapping Tape made of 94% kraft paper and 6% water-soluble eco-friendly adhesive. Paper strapping tape has a break force of 25 to 150 kg, elongation of only 3-8%, and roll lengths up to 4000 m. It is compatible with manual tools, semi-automatic and fully automatic strapping machines, and can be recycled with ordinary paper waste.

The market reflects this shift: rPET accounted for about 34% of global strapping production in 2024. Buyers with ESG targets, plastic packaging tax exposure, or export compliance requirements should evaluate whether their strapping supplier offers recyclable or plastic-free alternatives without forcing a full equipment change.

Step-by-Step: How to Evaluate a Plastic Strapping Manufacturer

Step 1: Define your load profile

Start by recording the weight per bundle, the type of product, edge sharpness, storage duration, and whether loads sit outdoors. A cardboard carton of beverages has different requirements than a brick pallet or a steel coil. The load profile determines whether PP strap, PET strap, or paper strap is suitable.

Step 2: Match the material to the application

For light and medium cartons, PP strap is typically sufficient and economical. For heavy, sharp-edged, or high-compression loads, PET strap provides higher break force and lower elongation. For plastic-free packaging of lightweight goods, paper strapping tape is an option. Consider machine format as well: automatic lines require strap with good straightness and consistent wound rolls, while manual operations need flexibility and easy handling.

Step 3: Verify standards and certifications

Reliable manufacturers should be able to document ISO 9001 and ISO 14001 certification, plus product-specific compliance. In China, PET strap is tested against GB/T 22344-2018 and PP strap against QB/T 3811-1999. For international markets, ASTM D3950-23 and EN 13394:2001 are reference standards. Third-party SGS test reports provide evidence of breaking force and elongation values.

Step 4: Review production and quality control

Ask about production lines, in-house processes, and inspection points. Jushuo, for example, operates dedicated PET and PP lines, uses SSP equipment for PET, and applies six inspection procedures. The presence of in-house R&D and patent activity can indicate process control capability. Avoid suppliers that cannot explain how their strap is manufactured or tested.

Step 5: Check capacity and delivery reliability

For large or recurring orders, confirm annual capacity, monthly output, and on-time shipment performance. Jushuo’s annual capacity exceeds 20,000 tons and its stated on-time shipment rate is 98.6%. Custom orders, such as printed PP or PET strap, typically require 15-20 days, while stock items can ship in about 7 days.

Step 6: Request samples and test on your line

A specification sheet is not enough. Test sample rolls on your actual strapping machine to check straightness, weld strength, tension retention, and jam rate. For manual operations, evaluate how easily the strap can be tensioned, sealed, and cut. This is the most reliable way to compare suppliers before a purchase decision.
