Introduction to Packing and Strapping

Packing, also referred to as strapping, involves securing items to a base, stabilising or reinforcing them with a strap—sometimes called a packing belt. This method is widely used across the manufacturing sector.

Steel Strapping and Packing

Steel strapping is among the oldest and strongest materials used for packaging and securing loads. Available in a range of widths and thicknesses, steel straps vary in quality and are primarily chosen for demanding applications requiring exceptional durability. The surface of steel strapping may be finished with paint, lacquer, wax, or zinc and wax coatings. Waxed strapping is particularly suited for use with certain tensioners, as it helps the strap better withstand tensioning force. Steel strapping is sold by weight rather than by length, as it can contract or expand during manufacture.

Polypropylene (PP) Strapping and Packing

Polypropylene is a cost-effective material designed for medium-duty strapping. It comes in various widths, thicknesses, and grades. A key characteristic of polypropylene strapping, which is not widely known, is that it loses half of its tensioning force within an hour, and this loss is accelerated by higher temperatures. Selecting an appropriate colour can help slow down the degradation of the strap when exposed to unsuitable outdoor temperatures.

Polyester (PET) Strapping and Packing

Polyester and nylon are the strongest plastics used for strapping, making them the preferred alternatives to steel in many industries. Polyester strapping is particularly effective at maintaining tension on rigid loads. The choice of tape depends on its intended application; for example, in colder environments, a weather-resistant hot-melt bonded strap is recommended.

Nylon

Nylon strapping offers the highest strength among plastic straps, but its relatively high cost means it is not commonly used. Once popular, it has largely been replaced by polyester strapping. Nylon is mainly used in cold storage, as it does not become brittle like other plastics.

Composite Strapping and Packing

Composite strapping contains embedded filaments and is often referred to in the industry as “synthetic steel” due to its high resistance to abrasion.

Fabric Strapping

Woven straps are produced in various constructions, typically using polyester or rayon. When used with a fastener, this system can provide even greater strength than steel strapping. Fabric straps are lightweight and flexible, making them a safer alternative to steel strapping.

Essential information about polypropylene (PP tape)

PP strap is a thermoplastic polymer produced from polypropylene monomers. It serves a variety of purposes, proving particularly effective for securing consumer goods, plastic components for numerous sectors, including the automotive industry, and more. Polypropylene was first identified in 1951 by Paul Hogan and Robert Banks. The material quickly gained popularity, with commercial production commencing just three years after its discovery. By 1957, its use was on the rise, and today, it stands as one of the most commonly manufactured strapping materials worldwide.

What is the most effective method for packing with PP polypropylene strap?

PP polypropylene strapping can be applied either manually or by machine. PP strap is suitable for securing cartons, parcels, and pallets. For optimal speed and efficiency when packing boxes, automatic or semi-automatic equipment is recommended, such as the HIPO semi-automatic packing machine. Both boxes and pallets may also be secured using a battery strapping tool. While battery strapping tools are suitable for pallet strapping, the quickest method for pallet applications is often a semi-automatic pallet strapping machine, which enables the strap to be fed beneath the pallet and sealed (welded) with the assistance of the machine. This process can be carried out, for example, with our COMBO pallet strapping machine.

What are the characteristics of polypropylene?

The foremost property is its resistance to chemicals. Polypropylene does not readily react with diluted acids or bases, making it ideal for packaging liquids such as cleaning agents, first aid supplies, and similar products. Another key attribute is its combination of flexibility and toughness. In engineering terms, toughness refers to a material’s ability to deform without fracturing. A further benefit is shape retention; polypropylene keeps its form after twisting or bending, offering greater durability than many other plastics. Additionally, it provides excellent insulation, being highly resistant to electrical currents, which is advantageous for electronic components. Lastly, it is lightweight. Although polypropylene can be manufactured to be transparent, it is typically not supplied in this form, but this option is available for applications where light transmission is required.

What makes polypropylene so widely used?

Polypropylene is predominantly utilised in industrial settings. Its distinctive properties and adaptability to various manufacturing processes make it indispensable across numerous applications. Another advantage is its versatility, as it can be processed into both plastic and fibre forms. In recent years, it has replaced many traditional materials, particularly within the packaging sector.

Which varieties of polypropylene exist?

There are two principal types of polypropylene: homopolymers and copolymers. Copolymers are further divided into block copolymers and random copolymers. Each type is better suited to particular uses. Polypropylene is often described as the “steel” of the plastics industry because of the many ways it can be tailored or modified for specific requirements. This is typically achieved by adding certain additives or through specialised processing techniques. This adaptability is one of its most significant qualities.

Industrial packaging and strapping – how to pack cost-effectively?

Industrial packaging holds equal significance to the product contained within. Its role is to support the efficient movement of goods to retail outlets and to aid in swift product identification. Above all, the primary function of industrial packaging is to safeguard the product. For this reason, packaging must be tailored to suit both its intended use and the storage environment. It is essential that industrial packaging fulfils all or some of the following requirements:

• It should possess sufficient strength and durability to bear continuous loads (such as heavy cardboard cartons stacked together)
• It must protect the product and, in the event of a drop, help to cushion the impact
• It needs to be adequately sealed to prevent ingress of moisture and air
• It must be resistant to weather conditions that could compromise the product’s quality
• It should be securely packed, reassuring the customer that the contents have not been previously opened
• Our packaging materials meet all these criteria, ensuring lasting customer satisfaction and encouraging loyalty. Customers should be aware that opting for inferior packaging materials may result in greater expenses later on, compared to investing slightly more at the outset for higher quality.

All these requirements become especially critical when products are subject to varying weather conditions or extended periods of transport. Selecting the appropriate approach is therefore vital, with the aim of minimising costs while ensuring the safety of packaged goods. Here are ten strategies for reducing industrial packaging expenses: 1. Assess the requirements of each product

1. Assess the requirements of each product

Carefully review the specified packaging needs for each item and compare these with your current methods (for instance, you may discover that both plastic film and lighter board are suitable for a particular product).

2. Ensure packaging boxes are appropriately sized

Industry experts recommend that there should not be more than 2 cm of space between the product and its packaging. Therefore, selecting smaller boxes is preferable, not only for a more compact package but also for reduced purchasing costs. Remove unnecessary layers and labels

3. Remove unnecessary layers and labels

Every extra layer of cardboard, foam, or similar material added to packaging increases expenditure. If robust protection is required, consider using fewer, but sturdier, layers. Additionally, limit the number of labels by placing one on the exterior and one inside the box.

4. Purchase plastic or textile/composite strapping in bulk

Investigate which suppliers offer discounts for bulk purchases. This does not always mean buying from the largest suppliers; smaller packaging suppliers with strong supplier relationships may offer the most competitive discounts.

5. Lower labour costs

Continually seek to enhance efficiency. This can be achieved by refining processes, maintaining equipment and tools, and providing ongoing training for staff.

6. Reuse materials where possible

With thoughtful planning, many packaging materials can be reused. Consider not only the materials sent to customers, but also those received with raw materials for your own production.

7. Maintain tools and equipment

Establish a preventative maintenance programme for packaging equipment and tools. Set up a regular inspection timetable and a system for tracking maintenance and documentation. Develop procedures for reporting and addressing issues. It is also wise to invest in a stock of the most frequently required spare parts.

8. Refurbish before replacing, and consider total cost

Where feasible, service or refurbish your existing equipment before opting for replacement. When purchasing new machinery, consider the total cost over its operational life, not just the initial price: a new machine with warranty, available spare parts, and service support may prove more economical in the long term than repeated repairs and downtime. Assess how crucial packaging equipment is to your business and the quality of your products.

9. Monitor price variations

The costs of materials like stretch film and steel strapping can vary greatly from one month to the next. Failing to keep an eye on these price movements may result in unexpected increases in your expenses. This is one of the main reasons why it is important to work with a supplier you trust, as it helps to minimise such risks.

10. Choose a supplier who can meet all your requirements

Working with a dependable, knowledgeable and professional supplier of packaging materials can lead to considerable savings. Your supplier should be well-informed about their product range and able to recommend the most suitable options for your needs. It is wise to select a supplier with whom you plan to build a long-term partnership, as they will gain a better understanding of your business and requirements. batterystrapping.com is an international supplier, providing all the essential strapping tools and materials for your packaging needs.

Packing with plastic strapping

The introduction of polypropylene (PP) and polyester (PET) plastic strapping for packaging purposes has led to these materials largely superseding steel strapping. This shift has been particularly notable in areas where steel banding was previously considered irreplaceable. The advancement of plastic strapping has opened up new opportunities for improved and more efficient packaging solutions. The distinctions between these two types of strapping are outlined below.

Key differences between steel and plastic strapping

Steel strapping is not characterised by significant elongation. In contrast, plastic strapping can stretch more within a certain range. A notable property of plastic strapping is its ability to revert to its original form after being stretched. Once tension has been applied, it is important to consider how much the strap can recover from its extended state.

The packaging of timber provides a good illustration of the move from steel to plastic strapping. While steel strapping is generally more robust for securing heavier items, plastic strapping stands out for its ability to regain its shape after being tensioned. This difference is crucial, making plastic strapping more suitable for applications such as timber packaging. Plastic strapping offers greater elasticity than steel, which, although elastic, does not stretch as much or return as effectively to its original length. In summary, steel strapping is more prone to breaking or loosening during transport, potentially leaving goods unprotected. Although steel can support heavier loads, in many situations, the flexibility of plastic strapping is a more significant advantage.

The shift from steel to plastic strapping

Plastic strapping is a more recent development compared to the long-standing use of steel strapping. However, technological progress is accelerating this transition. With the advent of advanced tools and innovative packaging methods, plastic strapping is expected to surpass steel strapping in the near future. Most leading manufacturers now acknowledge that switching from steel to plastic strapping is becoming standard practice.

Clarifying elongation, tension, and recovery capabilities

To fully grasp these concepts, it is important to understand the conditions under which strapping is used. Strap tension refers to the pulling force applied to the strap. As the strap is pulled, it stretches and elongates. The key question is whether it can return to its original length after being stretched. The elasticity of the strap is determined by the maximum extent to which it can be stretched and still recover its shape—this is often called the working range or endurance range of the strap.

Further details on the working range of PP and PET plastic strapping

The working range of strapping can vary significantly between different types. The best results are achieved when using a single type of strap, as this allows for the highest tension to be applied while still enabling the strap to return to its original form.

More information on the elasticity of PET and PP plastic strapping

The ability of a strap to return to its original shape is mainly influenced by the material, the amount of tension applied, and the duration of that tension. If the tension is only applied briefly, the strap is more likely to recover. However, if the tension is maintained for a longer period, the likelihood of the strap returning to its initial state decreases. Among the various options, straight plastic strapping is one of the best choices for retaining its original shape even after prolonged tension.

Securing or strapping goods is among the most widely adopted methods for grouping items within the packaging sector. Various types of strapping materials are available for bundling, which prove particularly effective in settings such as:

• fastening goods to pallets, crates, and similar units
• maintaining consistent loading and packaging of glass, timber, and metal components
• sealing cartons and parcels
• reinforcing wooden containers, crates, or boxes made from alternative materials
• securing items in place

Steel strapping is the most robust option, offering the greatest tensile strength, which ensures highly dependable packaging. It is supplied in a range of widths and thicknesses, with quality also varying. Steel strapping is predominantly chosen for securing items that are sharp-edged or exposed to high temperatures. When considering steel strapping for your packaging requirements, reflect on the following:

• Is the load both heavy and stable?
• Will the goods be transported over significant distances?
• Will they require loading and unloading multiple times?

If you answer ‘yes’ to these questions, then steel, composite, or PET strapping is likely the most suitable option.

Plastic strapping is generally better suited for lighter loads. It is available in a variety of widths, lengths, and polymer types. These straps offer greater elongation, though they may break if subjected to excessive force. Nonetheless, polyester strapping is considered by many industries as the leading alternative to steel strapping. For instance, polyester (PET) provides excellent tensioning force for rigid loads, and the strap itself is highly resistant to wear. It is important to differentiate between standard plastic and polyester strapping. Despite certain distinctions, plastic strapping is often referred to as “poly-bond”. The following points will help you tell them apart: firstly, polyester strapping is smoother; secondly, it can endure higher tensioning forces.

As packaging methods have evolved over the years, so too have strapping materials. It is worth noting that steel and plastic strapping remain the most popular and effective choices. Each type presents its own set of strengths and limitations, so it is advisable to assess which is most appropriate for your specific application before proceeding. It is not straightforward to declare one superior to the other, as both have their merits and drawbacks. The quality of strapping can also differ between suppliers, so it is prudent to review all the characteristics of the strapping offered and compare them with the requirements of your goods and loads before making a purchase.
