In some embodiments, the channel 110 is adapted to provide an opening which houses the transverse band 104 and an area of 20 to 200% of the width of the transverse band 104. In some embodiments, the channel 110 is adapted to provide an opening which houses the transverse band 104 and an area of 30% to 150% of the width of the transverse band 104. In some embodiments, the channel 110 is adapted to provide an opening which houses the transverse band 104 and an area of 40% to 100% of the width of the transverse band 104. [0070] In some embodiments, the ratio between the surface area of the outer surface of the films 112 at the adhered portion 106 and the surface area of the outer surface of the films 112 at the channel 110 is 8: 1, 6: 1, 4: 1, or 2: 1, or any value and range therebetween. For example, in the exemplary embodiment depicted by Fig. 1, the ratio between the surface area of the outer surface of the films 112 at the adhered portion 106 and the surface area of the outer surface of the films 112 at the channel 110 is 3: 1. In some embodiments, the width of the films 112 at the adhered portion 106 is equal to the width of the films 112 at the channel 110.

[0071] In some embodiments, the width of the channel 110 is defined as a distance across the channel llOwhich is parallel to the length of the longitudinal band 102. In some embodiments, the channel 110 is at least 2mm wider than the transverse band 104. In some embodiments, the channel 110 is at least 5mm wider than the transverse band 104. In some embodiments, the width of the channel 110 is l-20mm larger than the width of the transverse band 104.

[0072] In some embodiments, the width of the channel 110 is 5- 10mm larger than the width of the transverse band 104. In some embodiments, the width of the channel 110 is 1- 5mm larger than the width of the transverse band 104. In some embodiments, the width of the channel 110 is constant. In some embodiments, the width of the channel 110 varies. In some embodiments, the difference between the width of the channel 110 and the width of the transverse band 104 defines the range of distance in which the transverse band 104 is can adjust within the channel 110.

[0073] A potential advantage of the width of the channel 110 being larger than the width of the transverse band 104 is in that the position and/or orientation of the transverse band 104 is adjustable within the channel 110, which increases the adjustability of the structure of the net 100 independently form the elasticity of the longitudinal band 102 and/or transverse band 104.

[0074] A potential advantage of the longitudinal band 102 comprising a channel 110 is in that the surfaces of the transverse band can remain parallel to the surfaces of the longitudinal band within the channel 110, which maintains the net 100 flat. A flat net 100 can be rolled onto a roller during unpacking and/or for efficient storage. [0075] A potential advantage of the films 112 having a stronger adhesion than the adhesion within the channel 110 is in that the dimensions of the adhered portions 106 and/or channels 110 of the longitudinal band 102 are not altered by forces applied to the net 100. In some embodiments, the adherence of the films 112 prevents external forces applied onto the longitudinal band 102 from deforming the channel 110. In some embodiments, the adherence of the films 112 prevents external forces applied onto the transverse band 104 from deforming the channel 110.

Transverse Band

[0076] In some embodiments, the transverse band 104 comprises a cord, a wire, a belt, a film, a thread, and the like. In some embodiments, the transverse band 104 comprises at least a portion having dimensions sufficient to fit within the channel 110 of the longitudinal band 102.

[0077] In some embodiments, the transverse band 104 is flexible, semi-rigid, rigid, elastic, deformable, stretchable, ductile, and the like. For example, in some embodiments, the transverse band 104 is composed of materials such as steels, polymers, alloys, metals, polyethylene, plastics, elastic polymers, or any combination thereof.

[0078] In some embodiments, the thickness of the transverse band 104 is 0.03 to 2mm. In some embodiments, the thickness of the transverse band 104 is 0.05- 1.8mm. In some embodiments, the thickness of the transverse band 104 is 0.1- lmm. In some embodiments, the thickness of the transverse band 104 is 0.12-1.8 mm. In some embodiments, the thickness of the transverse band 104 is 0.04-1.3 mm. In some embodiments, the thickness of the transverse band 104 is constant. In some embodiments, the thickness of the transverse band 104 varies.

[0079] In some embodiments, the thickness of the transverse band 104 is smaller than or equal to the height of the opening of channel 110. In some embodiments, the thickness of the transverse band 104 is sufficient to fit within the opening of channel 110 such that the transverse band 104 abuts against both of the films 112 of the channel 110.

[0080] In some embodiments, the width of the transverse band 104 is shorter than the width of the channel 110. In some embodiments, the width of the transverse band 104 is 1- 50mm. In some embodiments, the width of the transverse band 104 is 0.2-30mm. In some embodiments, the width of the transverse band 104 is 0.5- 15mm. In some embodiments, the width of the transverse band 104 is 3- 17mm. In some embodiments the width of the transverse band 104 constant. In some embodiments, the width of the transverse band 104 varies.

[0081] In some embodiments, the transverse band 104 folds within the channel 110, such that the width of the transverse band 104 within the channel 110 is smaller than a flattened transverse band 104.

[0082] In some embodiments, the transverse band 104occupies 90% or less of the channel 110 area. In some embodiments, the transverse band 104 occupies 70% or less of the channel 110 area. In some embodiments, the transverse band 104 occupies 60-99% of the channel 110 area. In some embodiments, the transverse band 104 occupies 20-65% of the channel 110 area.

[0083] In some embodiments, the transverse band comprises a portion within the channel 110 and an outer portion 118 which remains outside of the channel 110. In some embodiments, the dimensions of the outer portion 118 are larger than then dimensions of the channel 110 (as described in greater detail elsewhere herein and depicted by Fig. 2B). For example, in some embodiments, the width of the outer portion 118 larger than the width of the channel 110. In some embodiments, the outer portion 118 is sized and positioned such that the transverse band 104 has limited mobility along the longitudinal axis of the transverse band 104. In some embodiments, the motion of the transverse band 104 within the channel 110 is limited by the portion 118.

[0084] In some embodiments, the transverse band 104 comprises the outer portion 118 at one side or both sides of the channel 110, such that movement of the transverse band 104 is limited within the channel 110. In some embodiments, the transverse band 104 comprises at least one outer portion 118 at at least one side of the channel 110, such that movement intersection 114 along the length of the transverse band 104 is limited in at least one direction.

[0085] In some embodiments, the distance between two consecutive outer portions 118 is 20-90mm. In some embodiments, the distance between two consecutive outer portions 118 is 30- 100mm. In some embodiments, the distance between two consecutive outer portions 118 is 40-60mm.

[0086] Reference is made to Figs. 2A and 2B, which are cross section views of exemplary embodiments of intersections within a net in accordance with some embodiments of the present invention. In the exemplary embodiments depicted by Figs. 2A and 2B, the longitudinal bands 204/214 comprise one film 210/224 on either side of the transverse bands 206/216 at each intersection 200/250.

[0087] In some embodiments, such as depicted by Fig. 2A, the channel 202 is shaped to accommodate the transverse band 206. In some embodiments, the channel 202 is shaped to accommodate the transverse band 206 at a range of orientations in relation to the longitudinal band 204.

[0088] In some embodiments, such as depicted by Fig. 2B, the width of the transverse band 216 varies. In some embodiments, the width of the portion 220 of the transverse band within the channel 212 is smaller than the width of the channel 212. In some embodiments, the width of the portion 218 of the transverse band 216 outside of the channel 212 is larger than the width of the channel 212. In some embodiments, the distance between the portions 218 of the transverse band 216 which are wider than the channel 212 determined the range of mobility of intersection 250 along the length of the transverse band 216.

[0089] In some embodiments, the channel 212 is asymmetrical. In some embodiments, the asymmetrical channel 212 prevents the transverse band 216 from sliding through the channel in only one direction along the length of the transverse band 216.

Intersection

[0090] In some embodiments, the net 100 comprises a plurality of intersections 114. In some embodiments, the intersection 114 comprises a first film, e.g. film 112-1, a transverse band 104 and a second film, e.g., 112-2. In some embodiments, the first and second films 112-1 and 112-2 are components of the longitudinal band 102. In some embodiments, at least a portion of the surface of the first film 112 is adhered to at least a portion of the surface of the second film. In some embodiments, one or both of the films 112 comprise sticky sides. In one embodiment, an intersection 114 comprises a transverse band 104 sandwiched between two films 112.

[0091] In some embodiments, an intersection 114 comprises a first portion comprising a first film 112, a transverse band 104 and a second film and a second portion comprising a first film 112 and a second film 112 without a transverse band 104. In some embodiments, an intersection 114 comprises 3 regions wherein the first and the third regions comprise the first portion and the second region comprises the second portion. In one embodiment, the second region is sandwiched between the first and third regions.

[0092] In some embodiments, the adhesion between the transverse band 104 and each of films 112 of the longitudinal band 102 is such that applying a force above a threshold value to the one of the bands of an intersection 114 changes the orientation of one band in relation to another.

[0093] In some embodiments, the adhesion between the transverse band 104 and the one or more of the films 112 of the longitudinal band 102 comprises lateral adhesion.

[0094] In some embodiments, the transverse band 104 is slidable within the channel 110. In some embodiments, the location of the intersection 114 along the length of the transverse band 104 is adjustable. In some embodiments, the orientation of the transverse band 104 is adjustable in relation to the channel 110 and/or the longitudinal band 102.

Reticulate Structure

[0095] In some embodiments, the net 100 comprises a reticulate structure. In some embodiments, the reticulate structure is symmetrical. In some embodiments, the reticulate structure is a grid or grid-like.

[0096] In some embodiments, at least one transverse band 104 is positioned within the channels 110 of the longitudinal bands 102 such that applying a pulling force onto the transverse band 104 reduces one or more of the width, length, or thickness of at least a portion of the net lOO.In some embodiments, and as explained in greater detail elsewhere herein, the structure of the net 100 is adjusted to form fittingly wrap a three-dimensional object. [0097] In some embodiments, the length of a diagonal of the net 100 is elongated by changing the position of the point of intersection 114 along the length of one or more transverse bands 104. In some embodiments, of the elongation ability of the net 100 is increased by removing a transverse band 104 from one or more channels 110.

Net tensioning control system

[0098] Referring now to Figs. 3A, 3B, 3C and 3D, which are plan view simplified illustrations of a net tensioning control system in accordance with some embodiments of the current invention. In some embodiments and as explained elsewhere herein, a net 300 comprises adhered portions 106 along longitudinal bands 102 one or more transverse bands 104 crossing one or more longitudinal bands 102 from one side of net 300 to another via one or more channels 312, similar to channels 110 described elsewhere herein, in a serpentine or zigzag manner. In some embodiments, net 300 comprises one or more transverse bands 104 which cross an edge-longitudinal-band 304 of net 300 in a serpentine or zigzag manner.

[0099] In some cases, net 300 may enclose items having an asymmetrical geometry, bulging and/or protruding portions. Therefore, in some embodiments, net 300 is stretchable at least along a longitudinal axis thereof. However, overstretching may, in some cases, bring about loss of elasticity of the net 300 fibers/bands or even tearing of the net fibers/bands. Hence, in some embodiments, net 300 comprises a net tensioning control system 350 that limits the extent of stretching of net 300 and prevents overstretching and possibly tearing of the net.

[00100] In some embodiments, net tensioning control system 350 comprises one or more transverse bands 302 that run through net 300 in a serpentine manner or zigzag manner. In some embodiments, net tensioning control system 350 comprises one or more transverse bands 302 that cross, circle and or surround an edge-longitudinal-band 304 of net 300 in a serpentine or zigzag manner. In some embodiments, band 302 runs through net 300 or cross, circle and or surround an edge-longitudinal-band following other patterns e.g., parallel to the edge or edges of net 300, in a crisscross pattern, a zig-zag pattern (Z-pattern or N-pattern) or any other pattern that is compliant with increasing tension on net 300 over a material being packed.

[00101] In some embodiments, and as shown in Fig. 3 A, transverse band 302 extends beyond the edges 304 of net 300 or an edge-longitudinal-band 304 by exiting and reentering channels 312 at adjustable intersections 114 at one or more edges 304 of net 300 to form one or more semi-loops 306. For example, transverse band 302 may exit at an exit point 308 from a channel 312 and reenter the edge 304 of net 300 via entry point 310 at a second channel 312. In some embodiments, transverse band 302 forms one or more semi loops 306 at predetermined locations, e.g., at locations disposed to tearing like at folds or bends of net 300. Alternatively, and optionally, transverse band 302 forms semi-loops 306 in a repetitive pattern throughout a dimension e.g., edge, of net 300. In one embodiment, edges 304 is or comprises an edge-longitudinal-band 304.

[00102] In some embodiments, transverse band 302 is threaded through net 300, for example, between the films 112 of a band and/or through channels 110 and/or a dedicated channel 312 shaped to have a geometry that corresponds to and supports accommodation of band 302. In some embodiments, transverse band 302 is at least partially adhered to net 300 at one or more locations in dedicated channel e.g., at a junction, an intersection or a crossing as explained in greater detail elsewhere herein. In some embodiments, adherence of transverse band 302 is the same at exit and entry points 308/310 as along adherence points in channels 110 and/or a dedicated channel 312. In some embodiments, adherence of transverse band 302 is greater at entry and exit points 308/310 than the adherence of transverse band 302 along adherence points in channels 110 and/or a dedicated channel 312.

[00103] The exemplary embodiments depicted in Figure pair numbers 3B/3C and 3D/3E, transverse band 302 forms a semi-loop 306 having a generally fixed length (L) and protrudes outside one or more edges 304 of net 300 between exit and entry points 308/310 located at a distance (Dl) from each other. As illustrated in Figs. 3B/3C, once net 300 is stretched, for example, in a direction indicated by an arrow designated reference number 375, the distance between exit and entry points 308/310 increases from a distance (Dl) to a distance (D2) i.e., (D2)>(D1) as a result of which semi-loop 306, having a generally fixed length (L), is drawn axially and straightens, parallel to the direction indicated by arrow 350 to conform to and be urged along its length against edge 304 of net 300.

[00104] In some embodiments, semi-loop 306 serves as a visual indicator of the amount of stretching of net 300 in that the amount of stretching of net 300 corresponds to the level of flatness or proximity of the length dimension of semi-loop 306 to edge 304 of net 100. To that effect, the length (LI) of semi-loop 306 depicted in Fig. 3B is designed to be generally equal to the post-stretching distance (D2) of net 300 between exit and entry points 308/310 (L1=D2). Hence, the length (L) of semi-loop 306 is equal to a maximal allowable distance (D2).

In some embodiments, the length (L) of semi-loop 306 is predetermined in accordance with a desired limit of stretchability of net 300. For example, and as shown in Figs. 3D and 3E, loop 306’ has a length (L2) that allows net 300 to stretch to a limited distance (D3), i.e., (L2=D3) wherein distance (D3) is greater than distance (D2) of Fig. 3C (D3>D2). In this example, (L2/L1) is proportional to (D3/D2).

[00105] In some embodiments, during stretching of net 300 there is at least some movement/sliding of transverse band 302 within cannels 110 of adjustable intersections 114 bringing about some distribution of transverse band 302 throughout net 300. This minor distribution of transverse band 302 has negligible if any effect on lengthening of semi-loop 306 along edge 304 of net 300 during stretching.

[00106] In some embodiments, the maximal allowable stretchability of net 300 depends on, for example, the material of which longitudinal bands 102 are made, the degree of adhesion of transverse band 104/302 within channels 312 and the density of transverse band 302 crossings. In some embodiments, transverse band 302 is made of a non-compliant material. In some embodiments, transverse band 302 is made of a material less compliant than the material of which net 300 is made e.g., having a Young modulus (Eband) equal to or smaller than a Young modulus of the net ( E _net ). In some embodiments, transverse band 302 is made of an elastic material the elastic limit of which is reached under tensile forces smaller than those required for tearing of the fibers of net 300. In some embodiments, the type of material of transverse band 302 depends on the degree of elasticity of net 300 or the desired degree of stretchability of net 300 regardless of the level of elasticity of transverse and longitudinal bands 104/102 themselves. [00107] Reference is now made to Figs. 4A and 4B, which are plan view simplified illustrations of net 300 tensioning system in accordance with some embodiments of the current invention. In some embodiments, semi-loop 306 serves as a physical limiter of overstretching of net 300. As shown in Fig. 4A, net tensioning control system 300 comprises a transverse band 302 semi-loop 306 locking portion 402 along one or more edge longitudinal bands (at the net’s longitudinal edge) 106 at one or more edges 304 of net 300 that stops the stretching of transverse band 302 from tearing net 300.

[00108] In one embodiment, edges or edge is a longitudinal edge. In one embodiment, an edge or edges comprise a portion of longitudinal bands positioned at the edges or the longitudinal edges of the net. In one embodiment, a net comprises 2 longitudinal edges. In one embodiment, each longitudinal edge comprises at least one longitudinal band. In one embodiment, each longitudinal edge comprises 1 to 10 longitudinal bands. In one embodiment, each longitudinal edge comprises 1 to 6 longitudinal bands. In one embodiment, each longitudinal edge comprises 2 to 4 longitudinal bands. In some embodiments and as explained elsewhere herein, net 300 transverse band 302 is disposed along adherence points in channels 110 and/or dedicated channels 312. In some embodiments, adherence of transverse band 302 within one or more channels 110 and/or a dedicated channel 312 at edge portions of net 300, e.g., along an edge 304 band 106, is stronger than the adherence of transverse and longitudinal bands 104/102 of net 300 at non edge 304 portions of net 300. This configuration forms a locking portion 402 along one or more edge portions of net 300, disposed between one or more channels 110 and/or a dedicated channel 312. In some embodiments, one or more portions of transverse band 104/302 are coated with an adhesive. In some embodiments, transverse band 104/302 is coated in its entirety with an adhesive. In some embodiments, one or more portions of transverse band 104/302 are welded and/or adhered to one or more longitudinal bands 106.

[00109] A potential advantage of this configuration is in that local variation in stretching of net 300 does not affect edges 304 of net 300 e.g., do not bring about tearing of edges 304. A potential advantage of a locking portion 402 is in that when net 300 is tensioned, locking portion 402 stops semi-loop 306 from moving from edges 304 inwards towards the center of net 300 in a direction indicated by arrow 395. [00110] In some embodiments, the ratio between the area (a) of locking portion 402 and the area (b), marked by broken lines 404, which comprises area (a) and includes channels 110 and/or a dedicated channel 312 is (0.1b>a). The area (b) of net 300 is determined by the density of net 300 longitudinal and transverse bands and not necessarily by the stretchability of net 300.

[00111] In some embodiments, one or more portions 402 along edge 304 band 106 may be strengthened by an increase in the density of net 300 the transverse and longitudinal bands 104/102, an added layer of net 300, an added layer of polymer or similar or any other strengthening mechanism.
