Abstract:
The present invention relates to Flexible Intermediate Bulk Containers (FIBC) having a body made of flexible fabric woven from polymeric tapes, and transport loops, wherein the body comprises side walls, bottom and top parts, characterised in that the fabric of at least one of the side walls and transport loops is woven from uniaxially-drawn PET tape having a density greater than 1.333 g/cm3.
Abstract:
A process for making a shaped part from a polymer selected from polyethylene terephthalate (PET) and polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) by using a compacting tool comprising a die having a cavity and a punch having an outer surface. The process comprises the steps of: a) placing particles of the polymer in the cavity of the die heated to a compaction temperature, wherein the polymer has an intrinsic viscosity of at least 0.45 dL/g wherein the particles are a mixture of first particles with a particle size of 0.5-4000 μm and second particles with a particle size of 1000-4000 μm b) pressing the particles in the die cavity at a pressure of at least 3 MPa for 5-15 minutes while maintaining the temperature of the die at the compaction temperature and c) removing the shaped part from the die cavity. When the polymer is PET, the compaction temperature is 235-259° C. When the polymer is PEN, the compaction temperature is 250-275 ° C.

Abstract:
The invention relates to an unidirectionally-oriented film comprising a thermoplastic polyester and a polycarbonate. The unidirectionally-oriented film may further comprise an anti-blocking agent and/or a slip agent. Depending on its width, the films of the invention may be used for food packaging; it may be used for strapping cartons, boxes, pallets, textile bales; and it may be used for woven tape fabric. The fabric woven from films of the invention may be used for making sacks, flexible intermediate bulk containers, hot fill jumbo bags for materials such as bitumen, PVC coated fabrics for flex signage, carpet backing, geo textiles, geogrids, metallised fabrics, and self-reinforced composites.
