What Are the Standard Widths of PP Strap?

The Width Question

If you have ever purchased PP strap, you have likely encountered this question: what width do you need? The answer is not always obvious. PP strap is manufactured in a range of standard widths, each serving different applications. According to Signode, a leading strapping manufacturer, PP strap is available in widths from 4.8mm to 17.5mm. BENZ Packaging confirms that the width range typically extends from 5mm to 19mm, with common sizes including 5mm, 9mm, 12mm, 15mm, and 19mm.

Choosing the right width is not simply about matching your equipment—it affects load security, carton protection, and overall packaging cost.

At Jushuo Packaging, our production data shows that width selection is one of the most common specification decisions buyers face, and choosing incorrectly leads to feeding issues in automatic equipment or inadequate load security.

1. Standard PP Strap Widths

1.1 Common Width Options

According to industry sources, the most common PP strap widths are:

According to Signode, widths of 12mm and 16mm are among the most frequently used in industrial applications. Other manufacturers offer 9mm and 15mm as standard options.

1.2 Custom Width Options

While standard widths cover most applications, some manufacturers offer custom widths within the 5mm to 19mm range. According to Bandma, custom widths are available based on specific requirements. Jushuo Packaging offers custom width specifications to match unique equipment or application needs.

1.3 Equipment Compatibility by Width

Not every width works with every strapping machine. According to equipment specifications, chute opening dimensions determine acceptable widths. Common compatibility guidelines:

• Table-top carton machines: 5–12mm

• Arch-type automatic machines: 9–15.5mm

• Pallet strapping systems: 12–19mm

• Semi-automatic machines: 5–19mm depending on model

Always check your machine's chute width tolerance before selecting a width. A mismatch causes feeding issues, jams, and costly downtime.

2. How Width Affects Performance

2.1 Load Distribution

Wider straps distribute tension across larger surface areas. According to packaging engineering analysis, a wider strap reduces pressure on any single point, minimizing the risk of carton damage or strap cutting into soft packages. For heavy loads or sharp-edged packages, wider straps are generally preferred.

2.2 Break Strength

Break strength correlates directly with width. According to industry technical data, a 5mm PP strap may offer approximately 45–60kg break strength, while a 19mm strap can deliver 240–355kg or more. Wider straps are stronger, but only if your equipment can handle the increased tension.

2.3 Carton Protection

A strap that is too narrow for the load creates stress points. According to BENZ Packaging, carton closure applications typically use 5mm to 9mm widths, while heavier bundling requires 15mm to 19mm. Choosing the correct width prevents edge crushing and ensures secure loads.

3. Width Selection by Application

3.1 Carton Sealing and Light Bundling

For standard carton closure and light bundling of printed materials, 5mm to 9mm is typically sufficient. According to industry guidance, light-duty applications do not require heavy strap, and using a wider strap increases packaging costs without adding meaningful protection.

3.2 Palletizing and General Industrial

For standard pallet loads, 12mm is the most common width. According to Signode's specifications, 12mm PP strap offers break strengths from 100kg to 175kg depending on thickness. This width balances load distribution, break strength, and equipment compatibility for most palletizing applications.

3.3 Heavy-Duty Bundling

For heavy loads, large pallets, or industrial applications, 15mm to 19mm is recommended. According to BENZ Packaging, 15mm to 19mm with higher break strength is suitable for heavy-duty bundling. Signode offers 19mm strap with break strengths up to 290kg.

3.4 Equipment-Specific Selection

If your strapping machine has a specific width requirement, that requirement takes precedence. According to equipment manufacturers, using the specified width ensures consistent feeding, proper tension, and reliable seals. Using a width outside specifications can cause significant problems regardless of the load weight.

4. Additional Considerations

4.1 Surface Finish: Smooth vs. Embossed

Width selection is independent of surface finish. According to Signode, both smooth and embossed finishes are available across most width ranges. Embossed finish improves feeding reliability in automatic machines, while smooth finish is often sufficient for manual applications.

4.2 Thickness and Width Relationship

Width and thickness together determine break strength. According to industry data, a 12mm strap may be available in thicknesses from 0.55mm to 0.70mm, with corresponding break strengths ranging from 1079N to 2060N. When selecting width, consider the required thickness for your break strength needs.

4.3 European Standards

In European markets, EN 13394 specifies strapping dimensions and testing requirements. According to industry standards, PP strap exported to EU markets must meet these specifications to ensure compatibility with European equipment and regulatory compliance. Buyers should verify that their chosen width and thickness meet EN 13394 requirements.

Summary

PP strap is available in standard widths from 5mm to 19mm, with common sizes including 5mm, 9mm, 12mm, 15mm, and 19mm. Width selection determines load distribution, break strength, and equipment compatibility. For carton sealing, 5–9mm is typically sufficient. For standard palletizing, 12mm is the most common choice. For heavy-duty bundling, 15–19mm is recommended. Always check your equipment's chute width specifications before selecting.
