Elastic Memory Load Securing That Compensates for Wood Shrinkage in Transit
Timber, plywood, and engineered wood products present a strapping challenge that no inelastic securing system can adequately resolve: wood is hygroscopic – it absorbs and releases moisture as ambient conditions change, causing measurable dimensional changes during storage and transit. A steel strap applied tightly at the sawmill can be dangerously slack by the time the bundle reaches the port, the timber yard, or the construction site, because the wood beneath it has dried and contracted. Pack Strap™ composite cord strap from Shivoham Fabtech solves this with elastic memory – an inherent property of the high-tenacity polyester PET yarn core – that allows the strap to actively recover tension as the load beneath it changes dimension.
The Engineering Challenges We Solve
Steel banding fails across three critical dimensions in timber and wood products logistics. Shivoham Fabtech manufactures Pack Strap™ to resolve each — providing a technically superior, rust-free, and elastic securing system for sawn timber, plywood, engineered wood, and construction material logistics across road, rail, and ocean freight.
Wood Shrinkage Causes Steel Banding to Go Permanently Slack
Green or partially seasoned timber bundles lose moisture during transit – particularly in heated containers, open rail wagons, and outdoor timber yard storage. As timber dries, it contracts. Steel banding is permanently inelastic and cannot follow this dimensional change — strap tension drops to zero, the bundle becomes unstable, and it presents a serious handling hazard on arrival. Pack Strap™ actively recovers tension as wood dimensions change, maintaining load security for the full transit duration regardless of moisture changes in the timber.
Rust Staining on Finished Timber & High-Value Wood Products
Corroding steel banding transfers rust marks directly onto timber surfaces – permanently staining sawn timber, veneered panels, engineered flooring, wooden doors, and decorative wood products destined for premium markets. For finished wood products where surface appearance determines commercial value, rust staining at any stage of the supply chain is commercially catastrophic. Pack Strap™ contains zero metal content and cannot rust, stain, or chemically contaminate any timber or wood surface under any transit or storage condition.
Surface Damage & Operator Safety Risk During Strap Removal
Removing steel banding from timber loads in yard environments, on construction sites, and at trading points frequently causes surface gouging when tensioned banding snaps back on cutting, and creates laceration risk for the operator. Pack Strap™ releases with significantly reduced snap-back force and produces no sharp cut edges -protecting finished timber surfaces and reducing operator injury risk at every point of delivery and unstuffing.
