A poly bag is a bag made from polyethylene film, in LDPE or HDPE. Here are the 7 main types, how to choose the material and thickness, how to measure a bag, and the details buyers most often leave out of a custom poly bag order.
Strap a pallet in both directions, keep straps off the bottom deck and away from fork tines, protect carton edges, and pick a strap that holds tension for the trip. Here are the 7 rules, a strength formula with a worked example, and the mistakes that loosen loads.
Stretch wrap holds padding, doors and drawers in place on furniture, but it doesn't protect finished surfaces from scratches. See which surfaces need padding first, the 5 most common ways furniture gets damaged under wrap, and which film to use.
Column stacking keeps the most box strength, interlocking keeps the load most stable, and overhang costs box strength with either one. Compare the 4 common pallet stacking patterns and see what each one asks of your stretch wrap.
LLDPE and LDPE are both low-density polyethylene, but LLDPE film stretches further and resists punctures better, while LDPE is clearer and easier to process. See the 5 differences, published resin data, and what to check in a stretch film quote.
Stretch film doesn't let water through, but a stretch-wrapped pallet isn't waterproof. See the five weak spots where water gets in, how to tell which one caused the damage, and what to add to keep loads dry.
PP strapping suits cartons and light-to-medium pallet loads; PET suits heavy loads and goods that need tension held for weeks. Here's how to choose, why width and break strength aren't enough, and when to use strapping with stretch film.
Stretch film is made by extruding LLDPE resin through a flat die onto a chilled roll, then winding it straight onto paper cores. Here is how Tuosheng Packaging makes cast hand and machine film, and how the rolls are checked before packing.
Most pallet wrap savings come from the wrapping line and the way film is packed and shipped, not from a lower price per kg. Here are 8 ways to cut stretch film cost, in the order we'd try them, and how to check each saving is real.
Put three stretch film quotes side by side and the cheapest roll is often not the cheapest film. One supplier prices per roll, one per carton, one per kilogram, each on its own shipping terms. And the rolls themselves rarely…
