Strapping is known as the common means for bundling and unitization in packaging industries. We can see many strapping products and their applications. Strapping is also used in vertical or horizontal bands. Edge protectors help to create the strap tension on load corners and then reduce significant damage by that tension. Strapping is also useful in the loops of holding locations such as skids, tractor-trailers, and rail cars.The main usages are seen in:
Bundling for shipping & handling: pipe, newspapers, concrete block, lumber, etc.Attachment of items into skids, crates, and pallets.Reinforcing crates, wooden boxes, gaylords, etc.Attaching things to flatbed trailers, flatcars, etc.Load securing for metal parts, packaged glass, bricks, etc.Closing shipping containers and corrugated boxes.Securing paper or steel coils.Holding textiles or agricultural products.Load securing within boxcars, tractor-trailers, and intermodal containers.
Main Strapping Available in The Market:
Steel Strapping: Steel has the highest strength strapping with a variety of gradings. It is mainly applicable towards heavy-duty works where we need minimum strength and huge desirable strength.
When you need to employ steel strapping, just confirm yourself with the following list of questions:
Does load need higher strength and stability?Do you need it for long distances?Would it ask for unloading and then loading frequently before reaching the final point?If the answer is steel strapping, you must need it.
Plastic Strapping:
Polyester Strap and polypropylene straps are the main plastic strapping.
Polypropylene is very economical for light & medium duty applications like bundling, palletizing, and unitizing. You will get it with various grades and variations of polymer. You will get a significant stretch that is sometimes irrecoverable.
Hence, we go for some rigid options like polyester strapping that is the right alternative for steel strapping. Polyester has excellent tension on heavy & rigid loads with some recovery features. It will tolerate all the impacts imposed by the load without any breakage. It would not show the same elongation as we have seen in propylene.
Plastic strapping is thus termed as ‘poly strapping’ without considering any specific details. It may be confusing for us, but we should remember this thing to mark the best Polyester Strap Manufacturer in India.
You will generally observe a matte-style finish and plastic-like feel with a polypropylene strap.Polyester provides a smooth and glossy strap without resembling any polyester fabric.We call poly strapping concerning polypropylene materials.Polyester works out best when you deal with higher tension while in polypropylene, we need only low tension.Because of numerous applications and designs, we can see various types of strapping in the present market. But mostly we will use either plastic or steel strapping. Each has its benefits and shortcomings, and so it is sometimes critical to discover the best from these two.
For a better understanding and close view, we must know some specific terms in the mechanical industry.
Tension: Any pull or push operation to tighten the strapElongation: It is the stretch found in the strap when tension is appliedRecovery of elongation: It is the elasticity found after tension removal.Working range: The strap cannot recover fully to its initial shape. But we need to find the sweet spot where the strap will do its best.Decay of Tension: With time, tension will be diminished and then we will see the exhibition of the perfect behaviour of the polyester. We can see the significant tension decay only in polypropylene.Break Strength: It is the sheer force applied for breaking the strap.Core size: The depth and diameter of the strap coil should correspond to the machine or dispenser in strapping.Thickness: The strap thickness is a very useful characteristic measured in inch fractions.Width: The physical strap width is another concern depending on which machine or tools are applied for the strapping purpose.
Final Discussion on Strapping:
You must learn that steel strapping has minimal usage. Hence, if you want some flexibility in work, you should go with plastic strapping. The plastic materials show perfect elongation and recovery under any circumstances as advised by Polyester Strap supplier in Gujarat. Later the straps should contract when the packaging wants to hold it tight.
Steel strapping has very elongation but a very good recovery time. Plastics have various polymers with excellent capacity and workload. Hence, you need to find the search criteria before applying the strapping material.
