The load moves because the film was applied without tension, not because it was too thin, though gauge matters too. Stretch film works by being pulled as it goes on, which is what generates the holding force, and a hand dispenser with a brake does that far better than walking round with a roll. Anchor at the pallet base and overlap each pass. See pallet wrap, cartons and packing tape.
