General technical information published by PAXOMER Inc. to support preliminary material evaluation. It is compiled from the sources cited on this page and has not been independently reviewed or certified by a professional engineer, laboratory or certification body. Values marked typical, illustrative or requiring confirmation are not specifications. Confirm properties, standard editions, regulatory status and suitability for your specific application with the manufacturer and, where the use is regulated or safety-related, with a qualified professional or the relevant authority.

Stretch wrap and strapping hold unit loads together for storage and transport. Stretch film, usually cast or blown linear low-density polyethylene, is stretched as it is applied, so that its recovery force contains the load. Strapping (polyester, polypropylene, steel or composite) is tensioned around the load or bundle and sealed. Edge protectors, corner boards, slip sheets and anti-slip layers complete pallet securing. Buyers specify film by gauge, pre-stretch capability, cling, puncture and tear resistance and load-containment force, and strapping by material, width and thickness, break strength, elongation and joint efficiency.

This page is for warehouse, logistics, packaging and plant engineers, and for buyers of pallet-securing consumables. It explains the products, the properties that decide load stability, the test methods that appear in specifications, and how to trial a change. It is separate from PE shrink film, which secures loads by heat shrinkage. It does not state that PAXOMER stocks or has qualified any product, and its tables are frameworks unless a value is attributed to a source.

A. Product identity and terminology

1. What are stretch wrap, strapping and pallet-securing products?

They are consumables that turn a pallet of goods into a stable unit load. Stretch film wraps the load and holds it by elastic recovery. Strapping applies concentrated force through tensioned bands, often over edge protectors. Load-securing accessories distribute strap force, protect corners, prevent slip between layers and keep wrap from cutting the goods.

2. Which product types are used?

Pallet-securing products (qualitative orientation)
Product	Typical use	Points to evaluate
Cast stretch film (machine and hand)	General palletising, quiet unwind, clarity	Gauge, pre-stretch level, cling, puncture
Blown stretch film	Sharp-edged or irregular loads	Puncture and tear resistance, cling
Pre-stretched film	Hand wrapping with lower effort	Holding force, consistency
Netting and vented films	Produce and loads needing airflow	Containment, ventilation
Polyester (PET) strapping	Heavy loads, replacing steel	Break strength, retained tension, joint efficiency
Polypropylene (PP) strapping	Light to medium bundles and cartons	Elongation, creep, joint method
Steel strapping	Very heavy, hot or sharp loads	Strength, corrosion protection, safety in handling
Edge protectors and anti-slip sheets	Strap and wrap protection, layer stability	Compression strength, friction

3. Which terms appear in specifications?

Gauge (µm or ga), pre-stretch (%), on-pallet stretch, containment force, cling (one-side or two-side), puncture and tear resistance, neck-down, wrap pattern, revolutions, top sheet, roping, strap width and thickness, break strength, elongation, retained tension, joint efficiency, friction weld, heat seal, seal and buckle, edge board.

4. Who buys these products?

Manufacturers that palletise finished goods, distribution centres, third-party logistics providers, building-products and metals producers that bundle long or heavy products, and exporters whose loads travel long routes by sea, rail and road. Operations teams own the wrap and strap settings; purchasing buys recurring consumables.

B. Properties and performance

5. Which stretch-film properties matter?

Gauge and the ability to pre-stretch without breaking; puncture and tear resistance on the load's edges; cling to hold the tail and layers; neck-down (width loss when stretched); and load-containment force after application. Laboratory tests describe film behaviour; ASTM D4649 provides guidance for selection and use and refers to individual test methods (S1). ASTM D5458 measures peel cling between film layers (S2).

Pallet-securing parameters to specify

Framework only. Values are product-, machine- and load-specific and must be stated by the manufacturer and confirmed on your loads and routes.

Pallet-securing parameters to specify
Property	Value or range	Unit	Test conditions	Test method	Grade or construction	Source	Verification status
Film gauge	per load	µm	Nominal and tolerance	Supplier data	Stretch film	None	Application-specific verification required
Pre-stretch level	per machine and film	%	Machine setting and film capability	Wrapper and film data	Machine film	None	Application-specific verification required
Peel cling	per film	N per stated specimen width (a result reported in gram-force must be labelled gf, not g)	Stretched or unstretched condition, specimen width and peel conditions as defined in the method; reporting basis to be confirmed from the full method text	ASTM D5458 (S2)	Stretch film	S2	Manufacturer confirmation required
Containment force	per load	N (or kgf where the gauge reads kilogram-force; kg is a mass unit and is not used)	Gauge type, contact size, pull distance and position on the wrapped load stated; no standard basis has been confirmed	Containment-force gauge (method to be agreed)	Wrapped pallet	None	Application-specific verification required
Strap break strength	per strap	N or kgf	Width and thickness stated	Strapping specification (S3)	Strapping	S3	Manufacturer confirmation required
Joint efficiency	per joint method	% of strap break strength	Joint type stated	Strapping specification (S3)	Strap joint	S3	Application-specific verification required

6. Which strapping properties matter?

Break strength and elongation set how much force a strap can carry and how it behaves under shock. Retained tension decides whether the strap stays tight after the load settles; polyester generally retains tension better than polypropylene, which can creep. The joint (friction weld, heat seal, seal or buckle) is often the weakest point, so joint efficiency must be specified with the method. ASTM D3950 covers nonmetallic strapping types and joining methods (S3).

7. How is load stability judged?

Load stability is the result of goods, pallet, pattern, wrap and strapping together. Containment force measured on the wrapped load is a practical check; transport simulation (vibration, drop, incline impact) and route monitoring show whether loads arrive intact. A change in film, gauge or wrapper setting should be validated on the actual loads.

C. Manufacturing and processing

8. How are these products made?

Cast stretch film is extruded through a flat die onto chill rolls, giving clarity and quiet unwind; blown film is extruded as a bubble, giving toughness. Both are often multilayer coextrusions with cling and release layers. PET and PP strapping are extruded, oriented and embossed; steel strapping is cold-rolled, heat-treated and coated. Consistency of gauge and orientation determines how evenly the products behave on machines.

9. How do wrapping and strapping machines affect results?

Stretch wrappers (turntable, rotary arm, orbital) set pre-stretch, carriage speed, revolutions and force-to-load; strapping machines set tension and seal parameters. Settings matter as much as the material: a premium film on a poorly set wrapper may perform worse than a standard film on a well-set one. Record machine settings during any trial.

10. Which problems are common?

Problems, possible causes and first checks
Problem	Possible causes	First checks
Film breaks on the wrapper	Pre-stretch too high, gauge variation, sharp edges	Pre-stretch setting; film lot; corner protection
Loads lean or shift in transit	Low containment force, poor pattern, no bottom lock	Containment measurement; wrap pattern
Tails unwind	Low cling, cold storage	Cling; film temperature
Strap loses tension	Creep (PP), load settling	Strap material; re-tension; load design
Strap joint fails	Wrong seal parameters, damaged strap	Joint method; machine settings
Crushed corners	Strap tension without edge protection	Edge protectors; tension

11. How should these products be stored?

Store film rolls in their packaging away from heat and direct sun, and allow them to reach the working temperature before use, because cold film behaves differently. Store polypropylene and polyester strapping dry and out of sun; protect steel strapping from moisture. Keep lot numbers for traceability.

D. Applications and qualification

12. Where are these products used?

Food and beverage palletising, building products and lumber, metals and coils, chemicals in drums and bags, paper and board, consumer goods distribution, agricultural produce, automotive parts, export loads and warehouse storage.

13. Which requirements depend on the application?

Long sea routes, rail transport and multiple handling steps demand more containment and moisture protection; cold storage changes film behaviour; outdoor storage requires UV-stabilised film; heavy or hot metals may still need steel strapping; retailer and carrier requirements may set load-stability rules. Collect these before comparing products.

14. What sustainability questions arise?

Downgauging and higher pre-stretch reduce plastic per load if containment holds; recycled-content film and strapping are available but need documentation and consistency; collection of used film depends on local systems. Document the basis of any recycled-content claim.

15. How should a buyer select candidates?

Describe the loads, pallet sizes, weights, edges and routes.
Record wrapper and strapping machine types and current settings.
Fix containment and load-stability targets.
Ask for product proposals with test data, and run trials on real loads.
Choose on cost per load and damage rate, not price per roll or coil.

16. How should a trial be run?

Wrap or strap representative loads with the candidate and incumbent at agreed settings; measure film use per load, containment force and strap tension; ship test loads on typical routes or simulate transport; inspect on arrival. Repeat after adjusting settings once, and record lots and machine settings.

17. Which documents should be requested?

Data sheets with test methods (including cling, puncture and tear for film; break strength, elongation and joint efficiency for strapping); recommended machine settings; recycled-content documentation; storage guidance; and change-notification commitments.

E. Procurement, comparisons and decisions

18. How do PET, PP and steel strapping compare?

Strapping materials compared (qualitative)
Material	Where it may be preferred	Trade-offs to evaluate
Polyester (PET)	Heavy loads, retained tension, safer handling than steel	Joint method, cost versus PP
Polypropylene (PP)	Light to medium loads, cartons	Creep and tension loss
Steel	Very heavy, sharp-edged or hot loads	Corrosion, handling safety, cutting hazards

For heat-shrink bundling, see PE shrink film and industrial bundling film.

19. How should cost be compared?

Compare cost per secured load: film or strap used per load multiplied by price, plus machine downtime, product damage and claims. A higher-performance film at a higher price per kilogram can lower cost per load if it allows higher pre-stretch or fewer revolutions without loss of containment.

20. What should a pallet-securing RFQ include?

Load types, dimensions, weights and edge conditions.
Routes, storage conditions and any retailer or carrier rules.
Wrapper and strapping machine types and settings.
Current products, consumption per load and damage history.
Recycled-content or other sustainability requirements.
Annual quantities and delivery locations.

Prepare and submit these through the RFQ brief.

21. Which manufacturer qualification questions should be asked?

Product range and test data; consistency of gauge and strength between lots; technical service for machine settings and load testing; recycled-content verification; manufacturing locations; and change control. PAXOMER does not confirm any manufacturer's capabilities on this page.

Engineering and purchasing FAQs

Each answer is general technical information, not a specification or a quotation.

What is the difference between stretch film and shrink film?

Stretch film holds a load by elastic recovery after being stretched; shrink film holds it by contracting when heated.

Can I switch to a thinner stretch film?

Possibly, if the thinner film can be pre-stretched and applied to give the same containment force. Validate on your loads and routes before changing.

Which test measures stretch-film cling?

ASTM D5458 measures peel cling of stretch wrap film, in stretched or unstretched condition.

Should I use PET or PP strapping?

PET usually suits heavier loads and keeps tension better; PP suits lighter loads. The load, route and joint method decide.

Why do my straps lose tension?

Polypropylene can creep under load, and loads can settle. Check strap material and whether the load design allows re-tensioning or a stronger strap.

Can PAXOMER supply stretch film or strapping?

This page does not confirm supply. Send the loads, routes, machines and volumes, and PAXOMER will review whether a suitable manufacturer-development opportunity exists.
