20110308982 | WRAPPER FOR METAL COILS - A wrapper for wrapping a cylindrical roll of coiled material, such as coiled steel, is a one-piece wrapper which covers the outer periphery, the ends and the inner periphery of the roll. The wrapper has a first portion for covering the ends and outer periphery and a second portion for covering the inner periphery. Draw strings are provided at the longitudinal edges of the first portion for cinching the wrapper against the ends of the roll. | 12-22-2011 |
20110281486 | RECYCLABLE, MULTI-LAYER PACKAGING MATERIAL CAPABLE OF WATER ABSORPTION AND DESORPTION - A composite sheet material suitable for use as a wrapping material having a layer of non-woven material formed from thermoplastic fibers or spunbonded fabric and a single or a composite water impermeable layer, the layers being laminated together. The composite impermeable layer may include a polymeric woven scrim for increasing the tensile strength and tear strength of the sheet. | 11-17-2011 |
20110177734 | STRETCHABLE SCRIM WRAPPING MATERIAL - An industrial packaging material comprises a woven scrim of stretchable thermoplastic tapes bonded to a stretchable non-woven water-impermeable layer. The scrim and the non-woven layer are made from a blend comprising a polyolefin and an elastomer. The thermoplastic tapes of the scrim have a degree of elongation before breaking in the range of 20% to 500%. | 07-21-2011 |
20080299368 | PACKAGING MATERIAL FOR METAL - A multi-layered packaging material for metal with improved anti-corrosion properties is made from polyolefins, preferably polyethylene. The material has a high tensile strength middle layer comprising a woven scrim, preferably made of high-density polyethylene tapes with decitex from 500 to 2500 grams per 10,000 meters. The woven layer is laminated on the outer side to a layer of low-density polyethylene. The outer layer has a very low moisture and vapor transmission rate and is almost impermeable. It protects the wrapped good from damaging elements in the atmosphere, including vapors and moisture. The middle layer is laminated on the inside to a polymer sheet, preferably low-density polyethylene, impregnated with a blend of corrosion inhibitors. The corrosion inhibitor blend comprises both volatile and contact corrosion inhibitors. | 12-04-2008 |
