Abstract
The invention relates to a tape comprising from (i) about 75 wt % to about 99.9 wt % of a thermoplastic polyester, (ii) from about 0.1 wt % to about 25 wt % of a linear low-density polyethylene and (iii) from 0 wt % to about 5 wt % of other components, said tape having a thickness from 5 μm to 300 μm and a width from 0.5 mm to 7 mm. This tape shows no twinning and sticking to other tapes after slitting, has very good mechanical properties. When the tape is wound, bobbins having a regular shape can be obtained.
Claims19
A tape comprising (i) from about 75 wt % to about 99.9 wt % of a thermoplastic polyester, (ii) from about 0.1 wt % to about 25 wt % of a linear low-density polyethylene and (iii) from 0 wt % to about 5 wt % of other components, wherein said tape has a thickness from 5 μm to 300 μm and a width from 0.5 mm to 7 mm.
Use of a thermoplastic composition comprising (i) from about 75 wt % to about 99.9 wt % of a thermoplastic polyester;
- (ii) from about 0.1 wt % to about 25 wt % of a linear low-density polyethylene;
- and (iii) from 0 wt % to about 5 wt % of other components for making a weavable tape.
A polyester tape comprising linear low-density polyethylene as a component, whereien the polyester tape has a thickness from 5 μm to 300 μm and a width from 0.5 mm to 7 mm.
A method for manufacturing bobbins, comprising
- cross winding a polyester tape comprising linear low-density polyethylene as a component, wherein the polyester tape has a thickness from 5 μm to 300 μm and a width from 0.5 mm to 7 mm, wherein the linear low-density polyethylene reduces tape-on-tape friction so as to manufacture cylindrical bobbins having a regular shape.
