[0317] 0.5cm 2A sample of a film (or layered structure) having a certain area is provided. A cross-sectional section is then made through the sample using a Leica Microtome 3050S. Before cross-sectional cutting, the sample is rapidly frozen in liquid nitrogen and stabilized at -30°C using a commercially available temperature control system from Linkam Scientific Instruments Ltd. The thickness of each individual layer of the sample is then measured using an Olympus BX51 optical microscope. The microscope generates a cross-sectional image, which is then analyzed using software provided with the microscope. Layer boundaries are marked in the image, and the software determines the thickness of the layer.

[0318] (Parameter ratio) The ratio of parameter P1 to parameter P2 is determined as follows: =P1 / P2. Here, parameters P1 and P2 can be, for example, the thicknesses of two layered substructures.

[0319] (Meltflow Index) Unless otherwise specified, the melt flow index (also known as the melt flow rate or melt index) is measured according to the standard ASTM D1238-10.

[0320] (Melting temperature) The melting temperature of the layers is determined according to the standard DIN EN ISO 11357-3:2011(E), which refers to the DSC method. The DSC method used is described below.

[0321] (Differential Scanning Calorimetry (DSC)) DSC measurement is performed as follows:

[0322] Sample preparation for differential scanning calorimetry (DSC): At least 1.0 mg of the sample is weighed using a Kern 770 precision balance from Kern & Sohn GmbH (Balingen, Germany). For this purpose, an empty DSC pan is tare-weighted on the balance, followed by the weighing of the sample. The pan is then sealed with a lid using a press. The lid should have small holes to prevent deformation of the pan during DSC measurement. The sample and crucible must not be deformed during DSC measurement. Care must be taken not to touch the sample or crucible with bare hands during sample preparation.

[0323] (Differential Scanning Calorimetry (DSC)): Differential scanning calorimetry is performed according to the standard DIN EN ISO 11357-1 (version 11357-1:2010-03). The following details are applied in addition to or in deviation from the standard. The calorimeter is a PerkinElmer Inc. DSC 8000. In the DSC method, heat flow is measured as a function of temperature. Therefore, the graph of the measurement is shown with heat flow (dQ / dt) as a function of the vertical axis and temperature (T) as a function of the horizontal axis. The endothermic direction is always upward, as noted in Note 2 of Section 3.1 of DIN EN ISO 11357-1:2010-03. Differential calorimetry of heat flow is performed according to Section 4.2 of the standard DIN EN ISO 11357-1:2010-03. In this case, the reference crucible is always empty, and the reference position is always used for temperature, in accordance with Section 3.10 of DIN EN ISO 11357-1:2010-03. Nevertheless, the reference crucible must always be used. The flushing gas used (Sections 5.5 and 9.1.2 of DIN EN ISO 11357-1:2010-03) is nitrogen. Before each measurement, the DSC instrument is calibrated using indium and zinc (according to Annex C of DIN EN ISO 11357-1:2010-03), which are the calibrating materials (Sections 3.2 and 5.4 of DIN EN ISO 11357-1:2010-03), in accordance with Sections 8.2 to 8.4 of DIN EN ISO 11357-1:2010-03. As recommended in DIN EN ISO11357-1:2010-03, 8.4.2, thermal calibration is performed using indium as the calibrator. The crucible is supplied to the calorimeter via an autosampler. Details about the sample (name, weight, measurement method, position on the autosampler, storage location (memory location)) are entered via an editor. The measurement is performed in dynamic mode (DIN EN ISO11357-1:2010-03, 3.9.5). In this case, the sample is first pre-treated by heating from 35°C to 160°C at a rate of 20°C / min and maintaining the temperature for 1 minute. The sample is then cooled to 35°C at a rate of 2°C / min. The measurement process is then carried out to 160°C at a heating rate of 20°C / min.

[0324] (evaluation:) For the evaluation of the measurement, only the second heating curve described above is used. The curve can be selected under the menu "curves," and then under "heat flow." The selected curve is colored blue, and the rest of the data is red and can be removed via "remove curve." The melting temperature can then be determined from the data by selecting "peak area" in the "calc" menu. The peaks are marked and then automatically evaluated. The sample has exactly the same number of melting temperatures as the number of endothermic peaks in its second heating curve. If the sample has multiple peaks, i.e., multiple melting temperatures, when a single melting temperature is referred to herein, it means the one with the lowest temperature.

[0325] (Oxygen transmission rate (OTR)) The OTR of the film is determined according to the standard ASTM D3985-05 (2010). The film sample to be tested is taken from a groove-free, unfolded area of ​​the film. The sample area is 50 cm². 2 The measurement is performed at an ambient temperature of 23°C and an ambient air pressure of 100 kPa (0.986 atm). The test equipment is the Ox-Tran 2 / 22, commercially available from Amatek Mocon. The measurement is performed without compressed air correction. A sample at ambient temperature is used for the measurement. One side of the sample (the first outer surface) is set to 0% oxygen and 90% relative humidity, while the opposite side of the sample (the further outer surface) is set to 100% oxygen and 50% relative humidity. Further settings and factors affecting the measurement (in particular, the remaining ones listed in point 16 of standard ASTM D3985-05 (2010)) are defined by the equipment used and the proper use and maintenance of the equipment in accordance with the manufacturer's handbook.

[0326] The layered structure, layered substructure, and layer OTR are determined for the film as described above.

[0327] (Tensile strength and elongation at fracture) Unless otherwise specified, tensile strength (both MD and TD) shall be measured according to standard ISO 527-1,-3:2018. Unless otherwise specified, elongation at break (also known as tensile fracture strain or tensile fracture elongation) (both MD and TD) shall be measured according to standard ISO 527-1,-3:2018.

[0328] (Drop test) To test a specific layered structure, 100 pouches are provided, each having a first sidewall, a further sidewall, and a bottom made from a layered structure (i.e., the sidewall and bottom are made from a film, which is then made from a layered structure). Each pouch is then filled with a liquid product of its nominal capacity. The pouches are then dropped from a height of 1.2 m. 50 pouches are dropped so that they land bottom-first. The remaining 50 pouches are dropped so that they land either on the first sidewall or the further sidewall. A pouch fails the drop test if any damage, such as a tear, is observed in the sidewall or bottom. The number of undamaged pouches indicates a pass in the drop test.

[0329] In the above, the nominal capacity is defined as the capacity for which the pouch is designed. For example, if a pouch is designed to hold 100 ml of liquid or paste, then 100 ml is defined as the nominal capacity of the pouch.

[0330] (Film puncture strength) Unless otherwise specified, film puncture force (also known as average puncture force) is measured according to the standard ASTM D5748-95:2019.

[0331] (Impact of darts falling) Unless otherwise specified, the impact of a dart drop shall be measured according to standard ASTM D1709-01, method A.

[0332] Herein, the present invention will be described by non-limiting examples and exemplary embodiments. [Brief explanation of the drawing]

[Figure 4] This is a flowchart of the method according to the present invention for manufacturing a container according to the present invention. [Modes for carrying out the invention]

[0335] (Drawing description) The drawings will be explained in more detail below.

[0336] (Figure 1A) Figure 1A is a schematic diagram showing a cross-sectional view of a first embodiment of the layered structure 100a according to the present invention. The cross-sectional view is taken perpendicular to the layers of the layered structure. As can be seen in Figure 1A, the layered structure has nine layers 101a to 109a.

[0337] Layer 101a contains at least 88% by weight of HDPE (e.g., a first polyolefin). Optionally, layer 101a may also contain 10% by weight or less of LLDPE (e.g., a second polyolefin). Layer 102a is placed in contact with layer 101a and is made from LLDPE (e.g., a third polyolefin). Layer 103a is placed in contact with layer 102a and is made from HDPE (e.g., a first polyolefin).

[0338] Both layers 104a and 106a contain maleic anhydride-modified PE. Layers 104a and 106a are fitted and positioned to function as adhesive layers (e.g., bonding layers). Layer 105a is positioned between layers 104a and 106a. Layer 105a is made from ethylene vinyl alcohol copolymer (EVOH). Layer 105a is positioned in contact with layers 104a and 106a. Layer 104a is positioned in contact with layer 103a, and layer 106a is positioned in contact with layer 107a.

[0339] Layer 107a is made from HDPE (e.g., a first polyolefin). Layer 108a is placed in contact with layer 107a and is made from LLDPE (e.g., a third polyolefin). Layer 109a, placed in contact with layer 108a, contains a blend of LLDPE (e.g., a blend of a second polyolefin, a third polyolefin, and a fourth polyolefin). The LLDPE blend constitutes at least 90% by weight of layer 109a. Layer 109a may further contain additives such as an antiblocking masterbatch and a slip masterbatch.

[0340] The layered structure 100a may include a color masterbatch added to one or more of the layers of the layered structure 100a. For example, the color masterbatch may be added to layer 102a, layer 108a, or both layers 102a and 108a.

[0341] Layers 101a, 102a, and 103a form part of the layered substructure A110a. Layer 101a is an example of layer A1, layer 102a is an example of layer A2, and layer 103a is an example of layer A3. Layers 104a, 105a, and 106a form part of the layered substructure B111a. Layer 104a is an example of layer B1, layer 105a is an example of layer B2, and layer 106a is an example of layer B3. Layers 107a, 108a, and 109a form part of the layered substructure C112a. Layer 107a is an example of layer C1, layer 108a is an example of layer C2, and layer 109a is an example of layer C3.

[0342] Figure 1A also shows that the layered substructure A110a has a thickness A smaller than the thickness C of the layered substructure C112a. This is preferable but not required. Both thickness A and thickness C are greater than the thickness B of the layered substructure B111a. This is preferable but not required.

[0343] In one preferred embodiment, layer 102a has a thickness greater than the thickness of layer 101a and / or layer 103a, more preferably greater than the thickness of both layers 101a and 103a. In one preferred embodiment, layer 109a has a thickness greater than the thickness of layer 107a and / or layer 108a, more preferably greater than the thickness of both layers 107a and 108a.

The difference in thickness between layers 104a and 106a is preferably less than 10%.

[0344] The layered structure 100a has a first surface 113a formed by the surface of layer 101a and a further surface 114a formed by the surface of layer 109a. The layered structure 100a is also asymmetric, for example, with respect to layer 105a. For example, the layer arrangement when moving from layer 105a toward the first surface 113a is different from the layer arrangement when moving from layer 105a toward the further surface 114a. This asymmetry is in the composition of layers 101a to 109a. This asymmetry is also preferable in terms of the thickness of layers 101a to 109a.

[0345] (Figure 1B) Figure 1B is a schematic diagram showing a cross-sectional view of a second embodiment of the layered structure 100b according to the present invention. The cross-sectional view is taken perpendicular to the layers of the layered structure. As can be seen in Figure 1B, the layered structure has seven layers 101b, 102b, 104b, 105b, 106b, 107b, and 109b.

[0346] Layer 101b comprises at least 95% by weight of HDPE (e.g., a first polyolefin). Layer 102b is disposed in contact with layer 101b and comprises at least 98% by weight of LLDPE (e.g., a third polyolefin).

[0347] Both layers 104b and 106b contain maleic anhydride-modified PE. Layers 104b and 106b are also fitted and positioned to function as adhesive layers (e.g., bonding layers). Layer 105b is positioned between layers 104b and 106b. Layer 105b is made from ethylene vinyl alcohol copolymer (EVOH). Layer 105b is positioned in contact with layers 104b and 106b. Additionally, layer 104b is positioned in contact with layer 102b, and layer 106b is positioned in contact with layer 107b.

[0348] Layer 107b comprises at least 98 wt% HDPE (e.g., a first polyolefin). Layer 109b, positioned in contact with layer 107b, comprises a blend of LLDPE (e.g., a blend of a third polyolefin and a fifth polyolefin). The LLDPE blend constitutes at least 97 wt% of layer 109b. Layer 109b may further contain additives such as an antiblocking masterbatch and a slip masterbatch.

[0349] The layered structure 100b may include a color masterbatch added to one or more of the layers of the layered structure 100b. For example, a color masterbatch may be added to layer 102b.

[0350] Layers 101b and 102b form part of the layered substructure A110b. Layer 101b is an example of layer A1, and layer 102b is an example of layer A2. Layers 104b, 105b, and 106b form part of the layered substructure B111b. Layer 104b is an example of layer B1, layer 105b is an example of layer B2, and layer 106b is an example of layer B3. Layers 107b and 109b form part of the layered substructure C112b. Layer 107b is an example of layer C1, and layer 109b is an example of layer C3.

[0351] Figure 1B also shows that the layered substructure A110b has a thickness A smaller than the thickness C of the layered substructure C112b. This is preferable but not required. Both thickness A and thickness C are greater than the thickness B of the layered substructure B111b. This is preferable but not required.

[0352] In a preferred embodiment, layer 102b has a thickness less than the thickness of layer 101b. In a preferred embodiment, layer 109b has a thickness greater than the thickness of layer 107b. In a preferred embodiment, the thickness of layer 107b is less than the thickness of layer 101b. In a preferred embodiment, the difference in thickness between layers 102b and 107b is less than 10%. Preferably, the difference in thickness between layers 104b and 106b is less than 10%.

[0353] The layered structure 100b has a first surface 113b formed by the surface of layer 101b and a further surface 114b formed by the surface of layer 109b. The layered structure 100b is also asymmetric, for example, with respect to layer 105b. For example, the layer arrangement when moving from layer 105b toward the first surface 113b is different from the layer arrangement when moving from layer 105b toward the further surface 114b. This asymmetry is in the composition of layers 101b to 109b. This asymmetry is also preferable in terms of the thickness of layers 101b to 109b.

[0354] (Figures 2A and 2B) Figure 2A is a schematic cross-sectional view of the container 200 according to the present invention, viewed from the side. The container 200 has an internal volume 201, which is formed between a first side wall 204, a further side wall 207 (side walls 204 and 207 partially enclose the internal volume 201), and a bottom 210. The container 200 also has a spout 202 (discharge means) for discharging the contents of the container 200. The discharge means 202 can be closed by a closing means 203, such as a screw cap. Taking the first side wall 204 as an example, the first side wall 204 has a first surface 205 and a further surface 206 (opposite the first surface 205). The further surface 206 faces the internal volume 201.

[0355] The first side wall 204 and the further side wall 207 are made from a film having a layered structure 100a or a layered structure 100b, as shown in Figures 1A and 1B, respectively. Layers 109a / 109b of the layered structure 100a / 100b are positioned closer to the internal volume 201 compared to layers 101a / 101b. Further surfaces 114a / 114b of the layered structure 100a / 100b form further surfaces 206 of the container 200 (i.e., layers 109a / 109b form further surfaces 206). The first surfaces 113a / 113b of the layered structure 100a / 100b may form the first surface 205 of the container 200 (i.e., layers 101a / 101b form the first surface 205), but the container 200 may also have a coating layer, for example, containing lacquer, and a printing layer containing ink, superimposed on the first surface 113a / 113b of the layered structure 100a / 100b. In the latter embodiment, either the surface of the printing layer or the coating layer may form the first surface 205 of the container 200.

[0356] The above films will be described using the layered structures 100a and 100b shown in Figures 1A and 1B, respectively. Please note that the layered structures 100a and 100b are examples of layered structures according to the present invention. Other layered structures according to the present invention can also be used in films.

[0357] Figure 2B is a schematic diagram of the container 200 according to the present invention as seen from the front. The first side wall 204 and further side walls are connected by the first edge 208 and further edge 209 to form the interior of the container 200.

[0358] (Figures 3 and 4) Figure 3 is a flowchart of method 300 according to the present invention for producing a film according to the present invention. In step 301, at least seven layers are simultaneously extruded using inflation film extrusion to obtain a film comprising at least seven layers. The at least seven layers have the following layered substructure: A. A layered substructure A comprising at least two layers A1 and A2, and optionally layer A3, i. Layer A1 has a density of 0.940 g / cm³ 3 Including the above HDPE, ii. Layer A2 has a density of 0.940 g / cm³ 3 Contains less than LLDPE, iii. If layer A3 is present, its density is 0.940 g / cm³. 3 Layered substructure A containing the above HDPE, B. A layered substructure B comprising layers B1, B2, and B3, i. Layers B1 and B3 are adhesive layers (also known as bonding layers), ii. Layer B2 is a layered substructure B containing EVOH, C. A layered substructure C comprising at least two layers C1 and C3, and optionally layer C2, i. Layer C1 has a density of 0.940 g / cm³ 3 Including the above HDPE, ii. If layer C2 is present, its density is 0.940 g / cm³. 3 Contains less than LLDPE, iii. Layer C3 has a density of 0.940 g / cm³ 3 A layered substructure C containing at least one LLDPE less than, They are placed. Layered substructure B is positioned between layered substructure A and layered substructure C.

[0359] Figure 4 is a flowchart of method 400 according to the present invention for similarly manufacturing a container according to the present invention. In step 401, a film according to the present invention is provided. The film can be obtained using the method described above with respect to Figure 3. In step 402, the film is folded to generate a first side wall and further side walls of a container, the side walls at least partially defining (e.g., enclosing) the internal volume of the container. At least one edge of the first side wall (e.g., the first edge) is connected to at least one edge of the further side wall. In an optional step 403, a discharge means such as a spout is incorporated into the container. [Examples]

[0360] The present invention will be further described by examples. The present invention is not limited to these examples.

[0361] In the following examples, spouted pouches (containers) with side walls made from films having different layered structures were investigated. The same layered structure is used for both the first and further side walls of each pouch, as well as for the bottom of each pouch. The films consist of a layered structure, and each film constitutes at least 97% of the thickness of the side walls and bottom of each pouch.

[0362] Layers C1-C3 are positioned closer to the internal volume of each container compared to layers A1-A3. Layers B1 and B3 are adhesive layers (binding layers) made of maleic anhydride-modified polyethylene. Layer B2 is made of EVOH.

[0363] (Example 1) Table 1 shows the different layered structures used in Example 1 and their effects on the spouted pouch. Unless otherwise stated, each layer contains 100% by weight of the components shown in Table 1. Where indicated, additives in the form of slip agents, antiblocking agents, and coloring pigments constitute approximately 6.5% by weight of the layer. The thickness of layer A1 varies by less than 5% among the examples in Table 1. This also applies to layers A2-C3.

[0364] Examples 1.1 to 1.5 are particularly preferred embodiments of the present invention.

[0365] The technical effects in Table 1 are as follows: • Puncture resistance: The pouch's resistance to punctures by sharp objects. "+" indicates high puncture resistance, and "-" indicates low puncture resistance. Improving puncture resistance is desirable. • Drop test: The pouch's resistance to damage when dropped or when pressure is applied to the pouch. "+" indicates high resistance to damage, and "-" indicates low resistance to damage. Improving resistance to damage is desirable. • Heat resistance: The pouch's resistance to damage when heat is applied, especially to its outer surface. "+" indicates high resistance, and "-" indicates low resistance. Increased resistance to heat damage is desirable. • Sealing temperature: The temperature required to seal the pouch by connecting the sections on the inner surface of the pouch and applying heat and pressure to those sections. "+" indicates that a lower temperature is required, and "-" indicates that a higher temperature is required. Furthermore, "++++" indicates a lower temperature compared to, for example, "+", and "----" indicates a higher temperature compared to "-". It is desirable to reduce the temperature required for sealing. • Stiffness: The rigidity of the pouch. A "+" indicates high stiffness, while a "-" indicates low stiffness. Generally, increasing stiffness is desirable. • OTR: Oxygen permeability rate through the sidewall of the pouch. "+" indicates a low OTR, and "-" indicates a high OTR. Furthermore, "++++" indicates a lower OTR compared to, for example, "+", and "----" indicates a higher OTR compared to "-". Reducing OTR is desirable. [Table 1(1)] [Table 1(2)]

[0366] (Example 2) Example 2 provides a pouch having a layered structure according to Example 1.4. In this example, the thicknesses of layered substructures A and C are varied as shown in Table 2. Layered substructure A has a thickness A, and layered substructure C has a thickness C. The thickness of the layered structure varies by less than 5% between Examples 2.1 to 2.3. Furthermore, the thickness of layered substructure B also varies by 8% between Examples 2.1 to 2.3. [Table 2]

[0367] The technical effects in Table 2 are the same as those given in Table 1 above.

[0368] By repeating the steps in Examples 2.1 to 2.3 using a pouch having a layered structure as described in any of Examples 1.1 to 1.3 and 1.5 to 1.10, similar results to those shown in Table 2 can be obtained. [Explanation of Symbols]
