Standard stretch wrappers are engineered for uniform geometries like boxes or straight bars, making them unsuitable for tools with complex profiles. A shovel presents a dual challenge: a long, thin handle and a wide, flat blade. Attempting to wrap this combination on a rotary table often results in unstable loads, film tearing, or incomplete coverage on the broad blade surface. This guide explains how a specialized ring-wrapper configuration resolves these issues, what specific customizations are required, and how to calculate film consumption for your production line.<\/p>\n
The primary challenge in packing shovels is accommodating the significant difference in cross-section between the handle and the blade while maintaining load stability. A standard wrapper that rotates the product cannot easily manage the weight distribution and geometry of a shovel without specialized jigs. The solution lies in a ring-wrapper design where the film ring rotates around a stationary or slowly advancing product. This approach ensures consistent film tension and coverage regardless of the product’s irregular shape.<\/p>\n
