Pallet strapping types and machine configurations

Pallet strapping machines apply a plastic or metal strap around a palletised load or product bundle, tension the strap, and weld or crimp the joint to secure the load. Strapping is used alongside or instead of stretch wrapping to hold pallets together — particularly for heavy loads, unstable column stacks, and loads that require a fixed strap position. Strap materials: PP (polypropylene) strap — the most widely used plastic strap for general-purpose pallet strapping; lower cost, lightweight, and available in a wide range of widths (12–19mm) and tensile strengths; standard for cartons, cases, and light-to-medium pallets. PET (polyester) strap — higher tensile strength and better retained tension than PP; suitable for heavier loads and loads that are subject to temperature cycling; used for steel coils, heavy timber, stone, and industrial products; in packaging, PET strap is used for heavy pallet loads or products requiring higher retained tension than PP can provide. Steel strap — the highest strength and rigidity; for extremely heavy loads (stone, metal, structural products); requires a crimping tool or steel sealer rather than a friction or heat weld. Pallet strapping machine configurations: horizontal strapper — applies a strap horizontally around the entire pallet (over the top of the load and under the pallet deck, or under the pallet runners); secures the load on the pallet from horizontal movement; standard for palletised loads in distribution. Vertical strapper — applies a strap vertically around the pallet load from side to side; used in combination with horizontal strapping for maximum load security. Automatic inline pallet strapping machines: the pallet travels through the arch of the strapper on a conveyor; the strap is automatically fed around the pallet, tensioned, and sealed in one cycle; fully integrated into the end-of-line conveyor after the pallet wrapper; available in single-arch (one horizontal strap per cycle), dual-arch (two straps simultaneously), and multi-head configurations.

Frequently asked questions

What is the difference between PP strap and PET strap for pallet strapping?

PP (polypropylene) strap is the standard for general packaging and pallet strapping — lower cost, flexible, and suitable for most carton, case, and bag pallet loads. PP strap has moderate tensile strength and adequate retained tension for standard distribution conditions. PET (polyester) strap has higher tensile strength, better retained tension (less relaxation over time and temperature changes), and better resistance to cutting than PP strap. PET strap is preferred for heavy pallet loads (500kg+), loads subject to temperature cycling (cold chain/warm ambient cycles), and industrial products (metal, stone, timber) where higher-strength strapping is required. PET strap machines use different sealing technology (heat seal or buckle) and higher-tension tensioner heads than PP strap machines.

Can a pallet strapping machine work without a conveyor?

Yes. Semi-automatic pallet strappers are used without an integrated conveyor — the operator moves the pallet to the strapper by fork-lift and manually feeds the strap around the pallet; the machine then tensions and seals automatically. Semi-automatic strappers are suitable for lower-volume operations or operations where pallet loads vary significantly in shape and size. Fully automatic inline strappers require a powered conveyor to carry the pallet through the strapping arch at a controlled speed and stopping position. For high-volume automated end-of-line operations, an inline automatic strapper integrated with the pallet conveyor is preferred.

How many straps are typically applied to a pallet?

The number of straps depends on the pallet height, load type, and distribution requirements. A standard palletised carton load typically has 2 horizontal straps — one near the top of the load and one at the midpoint. Heavy or tall loads may require 3 or 4 straps. For loads with weak horizontal integrity (e.g. stacked bags without an interlayer grid), additional straps prevent layer shifting. Strapping is often combined with stretch wrapping — the stretch wrap provides full surface containment and weather protection while the straps provide high tensile holding force at specific positions. The combination is standard for heavy industrial pallets and any pallet load with high-value or fragile contents.
