Abstract: The invention relates to a bag (3) having a filling space for bulk material, which filling space is delimited by a lower base (4), a circumferential wall (6), and an upper filling space closure (8) facing away from the lower base (4). The bag has at least one tear-open strip (10) for exposing an opening area (12) of the bag (2), which is delimited by an upper weakening line (14) and a lower weakening line (16), wherein both weakening lines (14, 16) extent parallel to the upper filling space closure (8), and the upper weakening line (14) is positioned between the upper filling space closure (8) and the lower weakening line (16). The bag (2) has a longitudinal seam (18) extending transversely with respect to the upper filling space closure (8). The upper and the lower weakening line (14, 16) begin in the area of the longitudinal seam (18).

Abstract: A packaging for an additive to be added to a plastic batch consists of a packaging film of thermomelting plastic material shaped to form a bag and a thermomelting polyolefin-based adhesive applied to the plastic film and forming closure seams for sealing the bag. The adhesive is moisture crosslinking and can be a hot melt. The thermomelting plastic material is identical to or compatible with a plastic material of the plastic batch to which the packaging and the additive are to be added.

Abstract: A bag for transporting moisture-sensitive goods has a bag wall made of a unilayer multi-ply laminate. The laminate has an outer ply of crepe paper, a central ply made of a barrier material forming a vapor barrier, and an inner ply of weldable thermoplastic plastic material. The bag wall also has bonding agent plies between the outer ply and the central ply and between the central ply and the inner ply.

Abstract: The method is used to determine the elastic bending behavior of coordinate measuring machines as a result of the measuring force and the position of measuring slides in the measuring range of the machine. Correction values are determined, which are used to compensate for measuring errors caused by machine bending. The correction values are a function of the position of the measuring slides and on the measuring force between the probe of the coordinate measuring machine and workpieces within the measuring range, and are established and stored for several positions. The method can be combined very advantageously with known methods for the correction of guideway errors, which were developed on the basis of a rigid model, and with methods for the dynamic correction of machine deviations caused by vibration of machine components.
