Process comparison
Shrink film contracts with controlled heat; stretch film secures a load through tension and cling. Use the packed unit and required result to choose the process.
Packaging comparison
Shrink wrapping and stretch wrapping use different films, machinery and pack principles. Shrink film is positioned around a product or group and heated so it contracts. Stretch film is elongated and wrapped under tension, commonly around palletised or bundled loads. The correct choice starts with the unit being packed and the required handling result.
| Decision | Shrink wrapping | Stretch wrapping |
|---|---|---|
| How the film is activated | Controlled heat causes the film to contract around the pack | Elastic recovery and cling hold film applied under tension |
| Common packed unit | Individual products, cartons, trays, multipacks, sleeves and bands | Pallet loads or grouped items that can be wrapped by rotating the load or film carriage |
| Typical machinery | Sealer or sleeve wrapper with a heat tunnel, chamber machine or sleeve-shrink system | Hand dispenser, turntable, rotary arm or other stretch-wrapping equipment |
| Primary engineering question | Can the film, seal and heat process create the accepted pack without damaging the product? | Can film tension and wrapping pattern stabilise the intended load without crushing or movement? |
Common comparison questions
The processes can both use transparent plastic film, but they should not be treated as interchangeable equipment choices.
No. “Pallet wrap” commonly refers to stretch film applied under tension around a pallet load. Shrink wrap is a heat-activated film process. Some large-load applications use specialist shrink covers, but that is a different system and should not be assumed from product shrink-wrapping machinery.
State whether the requirement is an individual pack, multipack, tray, carton or pallet load before selecting equipment.
Usually not as a direct replacement. Stretch film relies on overlap, tension and cling, while a retail shrink pack may require a controlled seal, clear presentation and close conformity around one product. The finish and opening method are different.
If the purpose is only temporary grouping or transit restraint, describe that requirement rather than specifying either film by name.
Specialist pallet shrink systems exist, but the shrink wrapping machinery on this website is primarily presented for products, cartons, trays, multipacks, bottles and sleeves. A pallet-load duty requires separate evidence for load stability, film construction, heat method and site safety.
Do not scale a product tunnel or sleeve wrapper to a pallet application without a purpose-designed review.
A suitable shrink-film route can create full enclosure when the film and sealing pattern close the required edges. Many sleeve-wrapped packs remain intentionally open at the ends, and stretch wrap normally relies on overlapping layers rather than a heat seal.
Full enclosure does not automatically mean watertight or sterile; the required barrier must be defined and tested.
Both processes can accommodate a range, but the practical answer depends on how often sizes change and what finish is required. Shrink wrapping may need film-width, guide, seal and recipe changes; stretch wrapping may need a different wrap pattern, tension and load support.
Compare the full changeover and acceptance method for the actual format family rather than assuming one process is universally more flexible.
Provide photographs, dimensions, weight, pack or pallet pattern, handling route, required protection, presentation, opening method, output and site constraints. Explain the problem to solve rather than naming a film process.
Lancing can then identify whether the enquiry belongs to this shrink-wrapping site or requires a different load-stabilisation solution.
Process selection
Send pack or load photographs, dimensions, weight, handling route and required finish so the correct packaging process can be identified before machinery is compared.
