Shrink Wrap
Shrink wrap (stretch wrap) is a thick plastic film wound around palletized freight to stabilize and secure it during transport. Properly applied shrink wrap prevents freight from shifting, protects against moisture and dust, and is a basic requirement for most LTL shipments.
In Depth
Stretch wrap film comes in standard rolls (18-inch width, 1,500 or 5,000 linear feet) and machine-grade widths for automated wrapping equipment. Hand wrapping a standard pallet takes 3–5 revolutions at the base and top with cross-bracing in between — most shippers under-wrap, contributing to cargo claims.
Properly wrapped freight should have at least 3–4 layers of film around the entire pallet, with the wrap overlapping onto the pallet board itself to anchor the load. Film should be stretched to 50–75% tension for maximum holding strength without tearing.
For high-value or fragile freight, corner boards (cardboard or plastic angle pieces) placed at pallet corners before wrapping add rigidity and prevent crushing.
Usage Example
Example: 'The receiver rejected the freight because the shrink wrap was torn and several cases had shifted. We filed a cargo claim against the shipper's packing.'
Related Terms
Palletization
Palletization is the process of stacking and securing freight onto pallets for efficient handling, transport, and storage. Properly palletized freight protects cargo integrity, facilitates forklift handling, and can affect freight class determination in LTL shipping.
Load Lock / Load Bar
A load lock (or load bar, logistics bar, or cargo bar) is an extendable metal bar that wedges between the walls of a trailer to prevent freight from shifting forward, backward, or sideways during transport. They are essential cargo securement tools.
Bill of Lading (BOL)
A Bill of Lading (BOL or B/L) is a legal document issued by a carrier to a shipper that serves as a receipt for cargo, a contract of carriage, and a document of title. The BOL must accompany every shipment.
Cargo Insurance
Cargo insurance (also called motor truck cargo insurance) covers the freight a carrier is transporting in the event of theft, damage, or loss during transit. FMCSA requires a minimum of $5,000–$10,000 cargo coverage, though brokers commonly require $100,000.
Frequently Asked Questions
Is inadequate shrink wrap a cargo claim defense?
Yes. If freight shifts or falls due to inadequate shipper packing (including shrink wrap), the carrier's liability is reduced. Document condition at pickup.
