Heat shrink wrap10/29/2022 ![]() ![]() Most lighter heat shrink materials are used with consumer products such as chocolates, soaps, produce, baked goods, electronics, and more. The interlinking of the polymers makes a thinner yet stronger shrink film. The process of crosslinking polymers is done through the irradiation process. Cast rolls are the most common and can be used for wrapping skids with rough edges and jagged corners.Ī material that can be sealed and heat applied to shrink and conform to the item(s) being wrapped.Ĥ5 to 50 Gauge Heat Shrink Wrap – Many thinner heat shrink wrap materials are made from crosslinked polyolefin. ![]() Once the wrap reaches this thickness, machine rolls are often the only option due to the amount of tension needed to apply the material.īlown wrap in a thicker gauge is noisy from a machine roll but can provide superb holding strength and puncture resistance. ![]() View a detailed stretch film thickness guide to choose the proper strength for the items being wrapped.ĩ0-150 Gauge Pallet Shrink Wrap – Not much film past a 120 gauge is available for hand application. The thickness and type of wrap should be determined by the products being wrapped. Blown extrusion creates a more durable pallet shrink wrap with better puncture resistance. Many of the lighter equivalent materials are made with cast extrusion. Standard gauged pallet stretch/shrink wrap will have excellent stretching capabilities and puncture resistance.īlown and cast stretch wrap will significantly differ in this range of material thickness. Any loads under 2,000 lbs with no sharp corners can be wrapped.Ħ5-90 Gauge Pallet Shrink Wrap – Even some 60 gauge pallet wrap can be a standard stretch wrap. It does not have the best puncture resistance. An equivalent wrap is excellent for wrapping uniform pallets of boxes. It is not recommended for anything with sharp corners.Ĥ2-63 Gauge Pallet Shrink Wrap – An equivalent stretch wrap made to have standard stretch wrap load retention. Pre-stretched pallet shrink wrap is excellent for wrapping light skids of stacked boxes. Because the material is stretched, it becomes thinner and less puncture resistant. Converters use a regular 70 or 80-gauge stretch film and stretch it to 90% of the maximum stretch rate. This is slightly different than our post focused only on heat shrink wrap thicknesses, below describes common pallet and heat shrink thicknesses, strengths, and recommended uses.Ī material that stretches when pulled and conforms tightly around bundled items.Ģ5-37 Gauge Pallet Shrink Wrap – This is a pre-stretched film. If you have other forms of measurement, use a gauge conversion chart to help understand your film capabilities. The measurements below are stated in gauge and mil thickness. Since the usage and materials are vast, we will highlight both. Both are made differently and out of various materials and additives. Shrink wrap often refers to a few items: pallet shrink wrap and heat shrink wrap. ![]()
