Perforated Banding: A Practical Guide

Perforated banding is a versatile product used across many industries for bundling, securing, and protecting items. With its perforated design and adjustable closure system, perforated banding offers advantages over other securing methods like strapping or taping. In this guide, we’ll explore everything you need to know about perforated banding and how to utilize it effectively.

What is Perforated Banding?

Perforated banding, also known as perforated strapping, is a plastic banding material that contains a series of holes or perforations. It resembles a flat, wide strip with evenly spaced holes across its surface. The holes allow for air circulation and drainage when wrapped around items.

Perforated banding is commonly made from polypropylene plastic for its durability, flexibility, and resistance to weathering. It comes in various widths, typically ranging from 9/16 inch to 1 inch wide. The thickness varies from about .020 inches up to .055 inches thick.

The essential advantage of perforated banding lies in its adjustable closure system. It uses a buckle and tensioning tool to tighten and secure the banding once wrapped around an object. This differs from solid strapping that requires a metal seal.

Key Benefits and Uses

Perforated banding offers some clear advantages over alternatives:

Adjustable Tension

The buckle system allows users to adjust and customize the tension when securing items. This ensures a tight, compression fit without damaging delicate contents. The tension can be reapplied later if needed.

Reusable

Perforated banding is reusable and re-securable over multiple uses. The buckles allow for quick fastening and release while maintaining banding integrity. This makes it more sustainable and cost-effective than disposable options.

Aeration and Drainage

The perforations allow for airflow circulation and drainage of moisture when banding is applied. This helps prevent condensation buildup and associated damage.

Protection

The snug fit offered by perforated banding protects contents from shifting during handling and transportation. This prevents breakage, damage, and product loss.

Versatile Applications

Perforated banding can bundle and unitize a wide variety of items across many industries:

• Warehousing – Bundling crates, boxes, drums, lumber, metal coils, etc.
• Agriculture – Securing bales of hay, straw, cotton, etc.
• Forestry – Binding logs, firewood bundles, and lumber loads.
• Construction – Banding pipes, rebar bundles, roofing materials, and more.
• Postal & Courier – Securing envelopes, packets, polybags.
• Food & Beverage – Binding produce, meats, canned goods.

Clearly, perforated banding has become an essential, versatile product relied on by many industries. But what are the key properties and equipment needed to apply it effectively?

Properties of Perforated Banding

To utilize perforated banding, it’s important to understand some of its key properties and variables:

Banding Width

This refers to the width – usually from 9/16 inch up to 1 inch. Wider banding provides more surface contact and gripping power. But it also requires more tensioning force.

Band Thickness

Thickness ranges from .020 to .055 inches normally. Thicker banding is stronger but less flexible. Consider the tensioning tools to be used when choosing thickness.

Tensile Strength

The tensile strength indicates the banding’s breaking point when stretched. Polypropylene banding offers tensile strength between 150-300 pounds typically.

Elongation at Break

Elongation measures how much the banding stretches before breaking. Values of 15-35% are common. Higher elongation allows more flexible wrapping.

Perforation Size

Hole size ranges from 1/8 to over 1/4 inches. Smaller holes maintain more band integrity while larger holes increase airflow.

Buckle and Tooling

Buckle strength and the tensioning/cutting tools used must match the banding properties like thickness and tensile strength.

Selecting the right specifications ensures effective, trouble-free banding application. Now let’s look at applying and tensioning perforated banding.

Applying and Tensioning Perforated Banding

While specialized banding machinery exists, perforated banding can also be applied manually as a low-cost alternative. Here is an overview of the basic process:

1. Cut Banding

Cut the banding to the required length using a sharp knife or banding cutter tool. Allow extra length beyond the item circumference to feed through the buckle.

2. Wrap Object

Wrap the banding around the middle of the item, keeping it flat and straight without twisting. Pull it snug.

3. Insert End

Feed the cut end of the banding through the buckle opening.

4. Tension the Banding

Use a banding tensioning tool to grip the loose end of the banding. Operate the tensioner to pull the banding snug around the object.

5. Cut Excess

Cut off any excess banding past the buckle using a cutter.

6. Inspect Banding

Visually inspect that the banding is tight and securely contains the object. The perforations should allow airflow.

Additional tension can be applied later if needed to re-tighten the banding if it loosens. Simply insert the banding back into the tensioning tool and re-tighten.

Now that we’ve covered the basics of working with perforated banding, let’s explore some best practices for optimal use.

Best Practices When Using Perforated Banding

Follow these tips to get the most out of perforated banding:

• When possible, use banding tools to create uniform, consistent tension. Manual tensioning can vary.
• Make sure banding buckle and tooling match the banding thickness and strength needs.
• Avoid loose banding that allows load shifting or compromises stability.
• Don’t wrap banding excessively tight that it damages contents or hurts end users.
• Inspect banding regularly when transporting loads over long distances. Re-tighten if needed.
• When reusing banding, check for damage like splitting or hole elongation before reapplying.
• Ensure good alignment when reinserting used banding into the buckle to avoid jamming.
• For heavy loads, use wider, thicker banding or double wrap multiple banding strips.
• Keep banding stored clean, dry, and debris-free for best performance.

Adhering to these guidelines will ensure perforated banding performs as expected. But it’s also useful to be aware of some potential downsides.

Disadvantages of Perforated Banding

While perforated banding has many benefits, it’s important to weigh some potential disadvantages as well:

• Limited strength – Perforated banding has lower break strength than solid plastic or steel strapping. It may not be suitable for very heavy loads.
• Bulky buckles – The plastic buckle creates a thicker section that may obstruct close item stacking.
• Loosening over time – Tension can relax over time, especially when banding very heavy loads. Periodic re-tightening may be needed.
• Susceptible to UV light – Direct sunlight exposure over time degrades and embrittles polypropylene banding. Banding life is reduced outdoors.
• Difficult banding removal – Unlike steel strapping, perforated banding cannot be cut off cleanly after use. The buckles complicate removal.

Being mindful of these limitations allows users to account for them and still utilize perforated banding in optimal situations. Proper band and buckle selection along with re-tensioning can help overcome these challenges.

Now that we’ve covered the key pros and cons, let’s explore some perforated banding innovations on the horizon.
