How to Stretch Wrap a Pallet Properly: Step-by-Step (and the Mistake Everyone Makes)

Stretch wrapping looks like the simplest job on the dispatch floor, which is exactly why it is done wrong so often. A poorly wrapped pallet falls apart in transit; a well-wrapped one still slides off the pallet if you relied on film alone. Here is the correct technique — and the limit you need to know about.

What stretch wrap actually does (and doesn't)

Stretch film binds the boxes to each other and adds a barrier against dust and moisture. That is genuinely useful. But film does not anchor the load to the pallet — it wraps the stack, not the connection to the deck. That distinction decides how you should use it, and we come back to it at the end.

How to stretch wrap a pallet — step by step

1. Build a tight, square load first

Wrapping cannot fix a bad stack. Stack boxes tightly with minimal gaps, evenly distributed, square to the pallet edges with no overhang. A wobbly stack stays wobbly under film.

2. Anchor the film to a corner

Tie or twist the film tail and secure it to one bottom corner of the pallet so it cannot pull free as you start.

3. Wrap the base — and catch the pallet

Apply at least three full layers around the base, and make sure the film goes under the top deck boards / around the pallet corners so the load is tied to the pallet itself at the bottom. A strong base is the foundation of the whole wrap.

4. Work upwards with 50% overlap

Spiral up the load, overlapping each pass over the previous one by at least 50%. Stretch the film until you feel clear resistance — but do not overstretch to the point of tearing. Consistent tension matters more than maximum tension.

5. Wrap the top and pull down

At the top, angle the film so it pulls downward on the load. This downward force is what resists the load shifting and toppling in transit.

6. Finish securely

Cut the film, press the tail firmly onto the load, and tuck the end under a corner so it grips and does not unravel.

Common stretch-wrapping mistakes

• Too little overlap — gaps weaken the wrap and let the load loosen.
• Inconsistent tension — some sections crush, others stay loose.
• Weak base — focusing on the top and under-wrapping the bottom.
• Not catching the pallet — film only around the boxes, not tied to the deck, so the whole stack can slide off.
• Too tight — crushes bottom cartons and tears the film.
• Too loose — never secures the load at all.

The limit of wrapping — and what to pair it with

Even a perfectly wrapped pallet has a ceiling: film binds boxes together but provides little vertical anchoring to the pallet, so under heavy vibration or a sudden jolt the unitised stack can still slide off the deck as one piece. For light loads that is acceptable. For medium and heavy loads, wrapping alone is not enough.

The complete method is strap to secure, then wrap to protect:

• Strapping passes tensioned PP or PET strap under the pallet and over the load, anchoring it to the base so it cannot shift — the securing.
• Wrapping adds the dust and moisture barrier on top — the protection.

And where hand wrapping struggles most — consistent tension — a machine removes the variation. The same logic applies to strapping: a calibrated system such as the ErgoPack 726X, GO or 700 applies repeatable tension on every pallet.

Stretch-wrap checklist

• Load stacked tight, square, no overhang
• Film anchored to a bottom corner
• 3+ base layers, film caught under the pallet corners
• Spiral up with 50%+ overlap, consistent tension
• Top layers angled to pull down on the load
• Film cut and tucked so it grips
• For medium/heavy loads: strapped first, then wrapped

Wrap to this standard and the film does its job — but remember the film's job is protection, not anchoring. For loads that matter, strap first.
