    Abstract: The present invention relates to a multilayer film comprising: • an inner layer system comprising a first surface and a second surface; • a first skin layer bound to the inner layer system at the first surface of the inner layer system; and • a second skin layer bound to the inner layer system at the second surface of the inner layer system; wherein • the inner layer system comprises ≥ 50.0 wt% with regard to the total weight of the inner layer system of a first ethylene-based polymer being a high-density polyethylene (HDPE) having a density of ≥ 940 and ≤ 970 kg/m3, preferably of ≥ 960 and ≤ 970 kg/m3, as determined in accordance with ASTM D792 (2008); and • at least one or both of the first or the second skin layer(s) is a sealing layer comprising a second ethylene-based polymer being a linear low-density polyethylene (LLDPE) comprising polymeric moieties derived from ethylene and from 1-hexene or 1-octene, having a density of ≥ 890 and ≤ 915 kg/m3 as determined in accordance with ASTM D792 (2008), preferably wherein the sealing layer comprises ≥ 70.0 wt% of the second ethylene-based polymer or wherein the sealing layer consists of the second ethylene-based polymer; wherein the multilayer film is a bi-directionally oriented film wherein the orientation in both directions is introduced in the solid state. Such film allows for the production of a sealed package having a sufficiently high sealing strength at reduced sealing temperatures, also referred to as the seal initiation temperature, whilst also having improved tensile properties, such as demonstrated by improved tensile modulus in both machine direction as well as in transverse direction, and improved tensile strength, also in both machine direction and in transverse direction.

    Abstract: A welding device (1) for making and hermetically sealing at least one package (P) containing a product (A), comprises a first and a second sealing and cutting equipment (2, 3). Each sealing equipment is configured to receive a respective film (F) forming a tubular envelope (F2), to seal it and cut it transversally for making at least one package (P). The welding device (1) comprises a support body (4), bearing the first and the second sealing and cutting equipment (2, 3), which is connectable to a packaging machine (100), preferably to a rotary drum (105) of a packaging machine (100). In particular, each sealing and cutting equipment (2, 3) comprises an arm (5) operating as a sealing and cutting head and an abutment body (6). Furthermore, the arm (5) is rotatably constrained to the support body (4) and reversibly movable between a plurality of positions comprised between an active position, wherein it is substantially in abutment on the abutment body (6), and an inactive position, wherein it is raised with respect to the abutment body (6). Furthermore, a locking means (20) is provided, adapted to lock the arms (5) in the active position in the welding step.
