Stretch film's core value — its ability to elongate and cling — can degrade with poor storage, even before the roll is ever used.
What affects stretch film in storage
- UV/sunlight exposure — can gradually degrade the polymer, reducing stretch capacity and cling performance over time.
- Extreme heat — can cause rolls to soften, deform, or partially fuse to their own core.
- Physical crushing — stacking heavy items on stretch film rolls, or storing them on their end rather than flat/upright as designed, can deform the roll and cause uneven unwind later.
- Extended storage of pre-stretched film — pre-stretched film (see the Pre-Stretched Film guide) can, over very long storage periods, experience some relaxation, though this is a slower effect than the factors above.
Recommended storage practice
- Store rolls upright on their core, not on their side, to avoid flat-spotting the film.
- Keep away from direct sunlight and extreme heat — indoor, shaded storage is best.
- Avoid stacking other inventory directly on top of stretch film rolls.
- For bulk stock, use first-in, first-out rotation, particularly for pre-stretched film.
Handling during use
- Load rolls onto dispensers/machines carefully — dropping or dragging rolls on rough surfaces can damage the outer layers before they're even used.
- Keep partially-used rolls in a clean, dry area between shifts rather than leaving them exposed on a warehouse floor.
Typical shelf life
Under reasonable storage conditions, stretch film generally maintains good performance for 12–18 months. As with tape, this is a gradual degradation rather than a hard expiry — for older bulk stock, a quick test wrap is worth doing before committing it to a critical shipment.
