Stretch Wrap & Pallet Unitizing Guide 2026: Types, Technique & Compliance

Stretch wrap is the final step in the pallet supply chain -- and one of the most commonly done incorrectly. Under-wrapped loads shift in transit, fail retail receiving inspections, and create worker safety hazards. Over-wrapped loads waste film and cost more than necessary. This complete guide covers stretch film types, gauges, wrapping techniques, machine vs. hand application, OSHA compliance, and retailer-specific requirements for operations across Florida, Georgia, New Jersey, Maryland, and Delaware.

Stretch Film Types

Film Type	Gauge	Clarity	Strength	Best For
Cast stretch (hand)	70-90 gauge	Excellent	Good	Standard pallets, retailer compliance, FBA
Blown stretch (hand)	60-80 gauge	Hazy	Excellent	Sharp edges, heavy/irregular loads
Machine stretch film	47-80 gauge	Good-Excellent	Excellent with pre-stretch	High-volume operations with stretch wrappers
Colored stretch wrap	80 gauge typical	Opaque	Good	Load ID, security (not for Amazon FBA)
Black stretch wrap	80 gauge typical	Opaque	Good	Security / privacy shipments only
UV-resistant stretch	80-100 gauge	Clear/tinted	Good+	Outdoor storage, Florida sun exposure
VCI stretch wrap	80 gauge typical	Clear	Good	Metal parts / corrosion-sensitive loads

Florida and Southeast operations storing pallets outdoors should specify UV-resistant stretch film. Standard stretch film degrades rapidly in direct sunlight, losing cling and tensile strength within 2-3 weeks of outdoor exposure. UV-stabilized film extends outdoor hold time to 60-90 days.

Hand Wrapping Technique: Step by Step

Anchor the film. Pull out 18-24 inches of film. Fold the tail in half lengthwise to create a rope. Thread the rope under one corner of the pallet between the bottom deckboard and stringer. Pull tight to lock.
Wrap the base. Walk around the pallet making 2-3 passes at the very bottom of the load, overlapping the pallet deck itself. This prevents load from sliding off the pallet in transit.
Work upward with 50% overlap. Each pass should overlap the previous by 50% (half the film width). Maintain moderate tension -- stretch the film but do not over-tension lightweight or crushable products.
Wrap the top. Make 2-3 passes at the top of the load. Pull the film over the top surface and tuck under the top deckboard or fold over the load to secure.
Secure the tail. Cut the film and press the tail firmly against the load. Heat-seal with a lighter or tuck under a previous wrap layer. Never leave the tail free -- it can get caught in forklifts.
Verify labels are visible. Check all 4 sides -- shipping labels and barcodes must be scannable through the film.

Machine vs. Hand Wrapping Comparison

Factor	Hand Wrapping	Machine Wrapping
Labor per pallet	60-90 seconds	20-45 seconds
Film consumption per pallet	300-500 ft (higher)	150-300 ft (lower with pre-stretch)
Pre-stretch capability	10-20% (human-applied)	150-300% (machine-applied)
Wrap consistency	Variable	Highly consistent
Film cost per pallet (80 gauge)	$0.45-0.85	$0.20-0.45
Equipment cost	None	$1,500-25,000+ (turntable to rotary arm)
Breakeven volume	N/A	~50-150 pallets/day depending on equipment
Load containment force	Lower	Higher
Worker injury risk	Back strain from walking/bending	Low -- minimal operator movement

Stretch Wrap Requirements by Retailer

Retailer	Stretch Wrap Required?	Film Color	Label Visibility	Notes
Amazon FBA	Yes -- mandatory	Clear only	All 4 sides scannable	Colored/black film explicitly prohibited
Walmart	Yes -- required	Clear preferred	Required	Load must be stable through LTL transit
Costco	Yes -- required	Clear	Required	Display pallets: neat professional wrap
Whole Foods	Yes	Clear	Required	GFSI audit facilities inspect wrap quality
Trader Joe's	Yes	Clear preferred	Required	Not formally published -- Grade A standard implies wrapped
Aldi	Yes -- display pallets especially	Clear	Required	Shopper-visible pallets on sales floor
Home Depot / Lowes	Yes	Clear	Required	Heavy loads: use 90-100 gauge film
3PL / General freight	Best practice, often required	Any	Varies	Check carrier/3PL requirements

OSHA Pallet Unitizing Compliance

OSHA does not publish a specific stretch wrap standard, but several regulations require that palletized loads be secured and stable:

29 CFR 1910.176(b)

Materials must be stored in a manner that prevents hazard. Unstable pallet loads that can topple or shift create an OSHA-citable hazard. Proper stretch wrapping is the primary engineering control for pallet load stability.

29 CFR 1910.178

Powered industrial truck (forklift) safety regulations require that loads be carried safely. A load that is not unitized or is improperly wrapped increases the risk of load drop, tip-over, or shifting during forklift operation.

General Duty Clause (5(a)(1))

OSHA can cite employers under the General Duty Clause for recognizable hazards not covered by specific standards. Pallets loaded without stretch wrap that collapse and injure workers have resulted in General Duty citations. Document your wrapping procedures.

Load Height Limits

OSHA 1910.178 and ANSI/ITSDF B56.1 limit pallet load height to what can be safely transported by forklift without obscuring driver vision. Standard maximum is 60 inches loaded (including pallet deck) for most single-pallet configurations. Stretch wrap does not extend allowable height.

Pallet Unitizing Checklist

Pallet is structurally sound -- no broken boards or damaged stringers
Load is within weight capacity (2,800 lb GMA dynamic / 30,000 lb static)
Load overhang does not exceed 3 inches on any side
Film anchored at pallet base on first wrap
Minimum 2-3 base passes securing load to pallet deck
50% film overlap maintained on each pass upward
Minimum 4 complete revolutions around load (6 for heavy/LTL)
Top of load wrapped and film secured -- no free tail
All shipping labels and barcodes visible through film on all 4 sides
For Amazon FBA: clear film only, no colored wrap
For outdoor storage: UV-resistant film specified
Film tension consistent -- no crushing of lightweight items

Frequently Asked Questions

Standard hand stretch wrap for pallet unitizing is 80-gauge (20 micron) cast stretch film. For heavy loads (over 1,500 lb), use 90-100 gauge film. Machine stretch wrap (used with stretch wrap machines) is typically 60-80 gauge because machine application applies consistent pre-stretch of 150-300%, making thinner film perform like heavier hand wrap. For cold chain and outdoor storage, choose UV-resistant or enhanced cling stretch film.

Minimum 4 complete revolutions of stretch film around the pallet for standard loads. OSHA-aligned best practice for loads over 1,000 lb or loads destined for LTL freight (where pallets get moved multiple times) is 6-8 revolutions. Always anchor the wrap at the pallet base on the first revolution and fold or tuck the final wrap to secure the tail.

Cast stretch wrap is manufactured by extruding melted plastic through a flat die onto a cooling roller. It is clearer, quieter to apply, tears more easily, and is the most common type. Blown stretch wrap is manufactured by extruding plastic upward into a bubble that is then collapsed and wound. Blown film is stronger, more puncture-resistant, and better for irregular or sharp-edged loads but is more expensive and less clear. For Amazon FBA and most retailer compliance programs, clear cast film is the standard choice.

Colored stretch wrap is useful for load identification and security (tinted film obscures contents from view). However, Amazon FBA explicitly prohibits colored or opaque stretch wrap because it blocks label scanning. Many other retailers require labels to be scannable through the film. If you use colored wrap, verify your retail or 3PL customer explicitly permits it before shipping. Black stretch wrap should only be used for high-security or privacy shipments to non-retail destinations.

OSHA 29 CFR 1910.178 (Powered Industrial Trucks) and 1910.176 (Materials Handling) indirectly govern pallet unitizing. OSHA requires that stacked loads be stable and secured to prevent movement or collapse. Stretch wrap is the primary method for meeting this requirement for palletized goods. Loads that are not adequately unitized and cause collapse resulting in injury can result in OSHA citations for general duty clause violations (Section 5(a)(1)). Additionally, OSHA 29 CFR 1910.176(b) requires that loads not create a hazard during transport.
