Before 1973 - manual pallet unitising
Before stretch wrapping machines existed, warehouses relied on two methods to secure loads on pallets.
Steel or plastic strapping bound the load tightly to the pallet. It was time-consuming, the strapping material was costly, difficult to remove at destination, and steel strapping was hazardous when it snapped under tension.
Heat shrink wrap used a heat tunnel to shrink film around the load. Equipment was expensive, energy consumption was high, and the maximum pallet size that could be processed was limited by tunnel dimensions.
Both methods struggled to keep pace as logistics volumes surged following the post-World War II economic expansion.
1973 - the invention of stretch film and the first wrapping machine
In 1973, American engineers developed a polyethylene film with high elastic recovery that could be stretched by mechanical force and cling to itself without heat or adhesive. This was stretch wrap film.
The first commercial pallet wrapping machine appeared the same year: a simple turntable with a film carriage standing beside it. The operator placed the pallet on the turntable, pressed a button, and the table rotated while the operator guided the film by hand.
Commercial adoption was rapid because the capital cost was low, film consumption was far below heat shrink wrap, and throughput was many times faster than strapping.
1980s - pre-stretch technology
The most important efficiency breakthrough in the history of stretch wrapping arrived in the 1980s: the pre-stretch film carriage.
Instead of applying film directly from the roll, the film passes through two rollers rotating at different speeds. The speed differential stretches the film 100-200% before it contacts the pallet. The result: the same quantity of film covers two to three times the surface area, cutting film cost per pallet by 50-70%.
Pre-stretch remains the foundational technology in almost every stretch wrapping machine sold today. Machines with 250-300% pre-stretch capability are now standard on mid-range and premium models.
1990s - full automation
The 1990s saw the transition from semi-automatic to fully automatic operation across four dimensions:
Automatic film clamping - the machine grips the film tail and attaches it to the load without manual intervention at cycle start.
Automatic film cutting and wiping - at cycle end, the machine cuts the film and wipes the tail against the load to seal it.
Programmable wrap profiles - operators store multiple programs (different wrap patterns, tension levels, number of passes) and recall them by product code. No manual adjustment between pallet types.
Conveyor line integration - machines were designed to sit inline on roller conveyors, accepting pallets from upstream and releasing them downstream automatically. One operator could supervise a wrapping station processing 200-400 pallets per hour.
2000s - self-propelled wrapping robots
At the start of the 21st century, Italian manufacturer Robopac brought the self-propelled wrapping robot to market, reversing the fundamental relationship between machine and pallet.
Instead of the pallet moving onto a turntable, the pallet stays on the warehouse floor and the robot travels around it carrying the film carriage. This solved two hard limits of turntable machines:
No load limit - because the pallet never moves onto a rotating platform, there is no turntable capacity constraint. The heaviest loads can be wrapped.
No fixed location - the robot wraps wherever the pallet sits: a racking lane, a staging area, a loading dock. No floor space needs to be dedicated to a fixed machine.
Modern Robopac robots such as the Robopac Masterplat Plus TP3 available from ICD feature a touchscreen interface, storage for 10 wrap programs, 300% pre-stretch, and an API for WMS integration.
Current trends - IoT and warehouse automation
The current generation of stretch wrapping machines (2020s) brings four capabilities that make them active nodes in the warehouse management ecosystem:
IoT data transmission - the machine sends real-time data on pallets wrapped, film consumed, and maintenance alerts to the warehouse management system or a cloud dashboard.
WMS-triggered wrap cycles - instead of an operator pressing start, the WMS sends a wrap command automatically when a pick order is complete and a pallet is staged.
Vision-based load sensing - onboard cameras detect pallet height and load shape, adjusting the wrap profile automatically to give full coverage without wasting film on empty space above the load.
AI wrap optimisation - the system identifies load type and applies the optimised combination of wrap passes, overlap, and film tension learned from historical data for that product category.
Understanding how the machine works mechanically is useful context for evaluating which generation of technology suits your warehouse. See the full guide to stretch wrapping machine components and operating principles for the technical detail.
ICD Vietnam and stretch wrapping machines
Founded in 2011, ICD Vietnam was among the first specialists in Vietnam to supply stretch wrapping machines with full VAT invoicing and in-house technical service to the B2B market. ICD carries the complete range from entry-level semi-automatic turntable machines to Robopac self-propelled robots, covering every warehouse scale and throughput requirement.

Frequently asked questions about stretch wrapping machine history
1. When was the stretch wrapping machine invented?
The first commercial stretch wrapping machine was developed in the United States in 1973, the same year that stretch film (pre-stretchable polyethylene film) became commercially available.
2. What problem did stretch wrapping machines solve?
They replaced two slow and expensive pallet unitising methods - steel/plastic strapping and heat shrink wrap - with a faster, lower-cost process that scaled with rising post-war logistics volumes.
3. What is pre-stretch and why does it matter?
Pre-stretch uses two rollers at different speeds to stretch the film 100-300% before it contacts the pallet. The same roll of film covers two to three times the area, cutting film cost per pallet by 50-70%. Introduced in the 1980s, it remains the core technology of modern machines.
4. When did fully automatic stretch wrapping machines appear?
Full automation - automatic film clamping, automatic cutting, programmable wrap profiles, and conveyor integration - became widespread in the 1990s, allowing one operator to oversee 200-400 pallets per hour.
5. What is a self-propelled wrapping robot?
A self-propelled robot travels around a stationary pallet carrying the film carriage, rather than the pallet rotating on a turntable. Pioneered by Robopac in the early 2000s, it removes the load limit imposed by turntable capacity and allows wrapping anywhere in the warehouse without a fixed machine footprint.
6. What features do current-generation machines add?
Machines from the 2020s add IoT data transmission (pallets wrapped, film consumed, maintenance alerts), WMS-triggered automatic wrap cycles, vision-based load sensing to adjust wrap profiles automatically, and AI optimisation of wrap parameters by load type.
7. When did ICD Vietnam start supplying stretch wrapping machines?
ICD Vietnam has been supplying stretch wrapping machines to the Vietnamese B2B market since 2011, covering semi-automatic turntable models through to Robopac self-propelled robots, all with full VAT documentation and in-house technical service.
