The bags will be produced in LLD-PE and LD-PE, either by the use of virgin raw materials or by a certain percentage regranulate. The bags are basically manufactured with a thickness of 35 microns. We have long used bags of 28 microns. This has proven to be good, but it assumes that the quality requirements of Table 1 will be met. ØRAS want to minimize the consumption of plastic bags.

Table 1.

Quality parameters standard machine direction cross direction.

Impact strength (g) ASTM D1709> 85 g.

Tear strength (mN) ASTM D 1922> 320 mN> 1490 mN.

Tensile strength (MPa) ASTM D 882> 36 MPa> 27 MPa.

Elongation at break ASTM D 882> 570 %> 810 %.

Providers must document the bag's quality according to requirements of Table 1 by a test report by an independent ISO certified laboratory. It must be no older than 6 months old and shall be in Norwegian or Swedish.

Each new delivery shall be accompanied by documentation that the bags delivered satisfy the quality requirements of table 1.
