Straps produced from renewable raw materials
An extruded strap is produced of a material containing renewable raw materials and the ends of which strap can be welded together. A method for producing the extruded strap and a method for strapping an article using the extruded strap are also provided.
1. An extruded strapping tape which is uniaxially stretched and which is weldable with itself and which is made of a renewable raw material that is a poly lactic acid (PLA),
wherein the strapping tape has a width in a range of 4 millimeters to 32 millimeters,
wherein the strapping tape has a thickness in a range of 0.2 millimeters to 2 millimeters, and
wherein the poly lactic acid is made of at least of 90 wt. % L-lactic acid.
2. The strapping tape as recited in claim 1 , wherein the renewable raw material is modified with a coupling reagent which is selected from the group of: maleic acid derivatives, glycidylmethacrylate derivatives, methacrylic acid derivatives, organosilicon compounds, vinyl acetate derivatives or mixtures thereof.
3. The strapping tape as recited in claim 1 , wherein a weight average of a molar mass of the renewable raw material is in a range of 20,000 g/mol to 300,000 g/mol.
4. The strapping tape as recited in claim 1 , wherein a fiber content is a maximum of 10 wt. %.
5. The strapping tape as recited in claim 1 , wherein the strapping tape is stretched at least 1:3.
6. The strapping tape as recited in claim 3 , wherein the weight average of the molar mass of the renewable raw material is in a range of 100,000 g/mol to 220,000 g/mol.
7. The strapping tape as recited in claim 4 , wherein the fiber content is a maximum of 1 wt. %.
8. The strapping tape as recited in claim 1 , wherein the material of the strapping tape includes at least 70 wt. % renewable materials.
9. The strapping tape as recited in claim 1 , wherein the strapping tape is free of any fibers.
10. The strapping tape as recited in claim 1 , wherein a surface of the strapping tape is embossed.
11. The strapping tape as recited in claim 1 , wherein the strapping tape is wound onto a roll having a tape length in a range of 1000 meters to 8000 meters.
12. An extruded strapping tape that is uniaxially stretched, weldable with itself and made of a renewable raw material that is a poly lactic acid (PLA),
wherein the poly lactic acid is made of at least of 90 wt. % L-lactic acid,
wherein the strapping tape is free of any fibers,
wherein the strapping tape has a width in a range of 4 millimeters to 32 millimeters,
wherein the strapping tape has a thickness in a range of 0.2 millimeters to 2 millimeters,
wherein a surface of the strapping tape is embossed, and
wherein the strapping tape is wound onto a roll having a tape length in a range of 1000 meters to 8000 meters.
