Unboxing that protects: paper void-fill for fulfilment

Void fill has one job: occupy the empty space in a carton so the contents cannot travel. In a fulfilment operation that space exists in almost every parcel, because the pick is different every time and the boxes are not. One item, two items and a mixed basket all go into the same standard carton with different amounts of air left over.

Swiftpack is crinkle-cut kraft made for exactly that. It expands and tangles with itself, so a handful stays where the packer put it instead of migrating to one end of the box on a long van run. It fills around irregular shapes without being measured or cut to anything.

What it does not do is protect one particular face. Fill supports everything it touches equally. If a specific SKU keeps arriving with the same chipped corner, that corner needs a cushion, which is Envigour paper bubble, or the whole item needs wrapping in SwiftWrap honeycomb. More fill will not fix it.

Compare void fill on cost per parcel packed, not cost per roll or per kilo. The second half of that figure is time at the bench, and it is usually the bigger half. A material that takes ten seconds longer to apply costs more than one that is dearer by the roll, at any real order volume.

Time the whole motion, not the material. The seconds go on things that are easy to overlook: walking to a staging area for pre-inflated cushioning, cutting a sheet to size, holding a wrap closed to get tape onto it, refilling a hopper mid-order. Paper on a roll expands at the point of use, at the bench, which takes the fetching out.

Then look at what you store. Pre-inflated plastic cushioning is mostly air by volume: you pay to ship it, to rack it and to hold it near the bench through peak. Flat paper occupies a fraction of the same footprint until the moment it is drawn off.

The cheapest void fill is the void you never created. An oversized carton costs three ways: the fill bought to occupy it, the shipping band it pushes the parcel into, and the movement inside it that produces the damage in the first place.

Carriers price parcels on both actual weight and the space they take up. The volumetric method and the divisor vary by carrier and by contract, so work from your own rate card rather than a rule of thumb. Then measure your top hundred SKUs and cut the box range down to the sizes they actually fit. It is usually the single change that removes the most fill and the most damage at once.

A material change only shows up in the damage figures if every bench applies it the same way. Through peak, benches are staffed by people who joined last week, and the pack they produce is whatever the bench makes obvious.

Write the standard by job rather than by material. Fill the space with Swiftpack. Wrap the fragile item in SwiftWrap. Cushion the face that keeps getting hit with Envigour. Name the box for each of the top SKUs, photograph the finished pack and put the picture at the station. A photograph settles arguments a specification does not.

Then check it with the box. Close the parcel, tilt it, shake it gently. If the contents shift, the pack is not finished: either more fill or a smaller box. That test takes two seconds and it is most of the quality control a pack bench needs.

For most online brands the parcel is the only physical object the customer ever receives, and it turns up after the money has been spent. That is the one moment where the experience can only be confirmed or ruined, and what the packer did at the bench decides which of the two it is.

Paper reads as considered, and it behaves well on a kitchen table: it does not cling with static, it does not need scissors, and it does not shed a bagful of loose pieces across the floor. A parcel that comes apart into one material also leaves the customer one simple thing to do with it rather than a sorting job.

Be accurate about the claim you print. The Swift range is paper with no plastic content, and Toreto holds FSC Chain of Custody certification, FSC-C227420 issued by SGS, covering responsible fibre sourcing. It is not a food-grade certificate. What a household or business collection actually accepts is set by the local authority and differs between them, so state what the material is and let the local rules apply.

Most fulfilment operations wrap pallets as well as parcels, into stores, depots and returns hubs, and the same question applies at that end of the building: what does one unit cost to secure, in material and in minutes? It is answered with the same two instruments, a set of scales and a stopwatch.

Toreto's own wrap tests, run in August 2026 on the same pallet and the same machine, put Supersonic and Aerosonic at 16µ at 66 g of film and about €0.32 a pallet, holding 10 kg per square inch. A 23µ solid film measured 9.9 at 200 g and about €0.48. Costs move with film price and pallet size.

For hand-wrapping there is a second measured test, run in the UK. The same pallet was rewrapped from the Hyper Wrap System dispenser: two minutes became one, and £1.00 became £0.74, with labour at 20p a minute. Around 50% fewer metres of film went onto the load, while the weight only fell from 181 g to 151 g, because the film is stronger and wider. Half the wrap time reads at despatch as twice the pallets per shift.
