Title:
COMPOSITION OF THERMOPLASTIC POLYURETHANE SHEET FOR BAG OR BILLFOLD
Document Type and Number:
WIPO Patent Application WO/2019/013450
Kind Code:
A1
Abstract:
The present invention suggests a composition of a thermoplastic polyurethane sheet for bags or billfolds, in which a sheath of the bags or billfolds is manufactured with a TPU sheet, which is an environmentally friendly material and exhibits excellent physical properties, but not with a PVC sheet, which is an environmentally regulated material, whereby excellent elasticity and resiliency, which are original material characteristics of TPU sheets, solve the drawback in that it is difficult to form a part at which folding occurs to shape a bag or billfold and good formability (foldability) can be achieved without changing physical properties of TPU.
