Description

AREA OF INVENTION

[0001] The present invention relates to packaging technology, in particular a reinforced handle that is glued onto the packaging. The handle can be glued onto a heat-shrinkable packaging film, and after shrinking, a packaging system with integrated reinforced handles is formed. This innovation addresses material specifications, synchronization methods, and adhesive strategies for creating a robust and recyclable packaging solution that enhances both aesthetics and functionality. BACKGROUND OF THE INVENTION

[0002] In the field of packaging technology, there is a constant search for efficient and reliable systems that can handle different product shapes and sizes while simultaneously optimizing the packaging process. Heat shrink films are frequently used to package products such as bottles, cans, and electronic devices, and are typically made of materials like polyolefin (PO) or low-density polyethylene (LDPE). These films conform to the shape of the product when heated, ensuring a secure fit. However, existing shrink film solutions often require additional components, such as separate handle attachments, which can increase manufacturing time, costs, and complexity.

[0003] Current methods focus on achieving the necessary tensile strength and structural support by relying on materials and processes that do not fully exploit the dual functionality of films for picking up and carrying. This often requires the attachment of external handles or the use of thicker materials, which can conflict with environmental sustainability goals. Furthermore, separate handle attachments add extra steps to the packaging process, leading to inefficiency and increased material consumption.

[0004] A significant drawback of existing solutions is that the handles cannot be efficiently integrated into the packaging film itself, resulting in uneven weight distribution and a higher risk of tearing, which can make carrying heavy loads difficult. Furthermore, the materials used are not always recyclable and do not meet standards for environmentally friendly packaging.

[0005] KR101175130B1 discloses a shrink film designed to incorporate a built-in handle for easier transport of packaged items. This is achieved by integrating a reinforcing film directly into the shrink film serving as the handle, thus eliminating the need for a separately attached handle.

[0006] However, the total amount of shrink film in the area where the reinforced film is integrated is reduced to maintain a similar overall film thickness across the entire package. This ensures that the total film thickness does not increase beyond standard specifications due to the addition of the reinforced layer. Maintaining a consistent film thickness is crucial to avoid the need for more frequent roll changes during production, as thicker films reduce the total length of film that can be wound onto a single roll, thus shortening operating intervals and decreasing production efficiency.

[0007] There is therefore an urgent need for packaging technology that eliminates the need for a separate device for attaching handles, reduces packaging time, and simultaneously ensures high mechanical strength. Such a system would increase productivity, reduce manufacturing costs, ensure recyclability, and maintain the durability and quality of the packaging. SUMMARY OF THE INVENTION

[0008] It is therefore an object of the present invention to disclose a reinforced film configured to adhere to packaging and to serve as a handle for a packaged product; the handle is arranged below the packaging, thereby improving the aesthetics of the packaged product; wherein the handle is configured to bear a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0009] It is therefore a further object of the present invention to disclose a reinforced film configured to adhere to a heat-shrinkable packaging film and to serve as a handle for a packaged product; the handle is arranged below the heat-shrinkable packaging, thereby improving the aesthetics of the packaged product; wherein the handle is configured to bear a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0012] In some embodiments, the reinforced film is an MDO (Machine Direction Orientation) film designed to increase the strength of the film.

[0013] In some embodiments, the reinforced film of the present invention complies with Regulation (EU) 2025 / 40.

[0014] In some embodiments, the reinforced foil also contains at least % Post Consumer Recycling (PCR) material, based on the weight of the handle.

[0015] In some embodiments, the reinforced film is characterized by an elongation at break between 10% and 120% in the machine direction.

[0016] In some embodiments, the reinforced film comprises low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), polyolefin (PO), polypropylene (PP), any combination thereof, or a derivative thereof.

[0017] In some embodiments, the reinforced film is characterized by a tensile strength between 80 MPa and 250 MPa in the machine direction.

[0018] In some embodiments, the reinforced film consists of materials that are approved for contact with food.

[0019] It is therefore a further object of the present invention to disclose a reusable heat-shrinkable packaging film comprising: (a) a heat-shrinkable packaging film configured to enclose an object and mechanically secure the object when heat is applied; and (b) a reinforced film that adheres to the heat-shrinkable packaging film and serves as a handle for a packaged product; wherein the handle is located below the heat-shrinkable packaging, thereby improving the aesthetics of the enclosed object; wherein the handle is configured to support a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0020] In some embodiments, the reinforced film is the reinforced film described above.

[0021] In some embodiments, the reinforced film is bonded by heat sealing, solvent-based adhesives, water-based adhesives, pressure-sensitive adhesives, extrusion coating and lamination, ultrasonic welding, or hot melt adhesives.

[0022] In some embodiments, the reusable heat-shrinkable packaging also contains additives.

[0023] It is therefore a further object of the present invention to disclose a method for producing a reusable heat-shrinkable packaging film, comprising: (a) providing a heat-shrinkable packaging film configured to enclose an object and mechanically secure the object when heat is applied; (b) providing a reinforced film (the reinforced film disclosed above) configured to serve as a handle; and (c) bonding the reinforced film to the heat-shrinkable packaging film; (b) providing a reinforced film (the reinforced film disclosed above) that serves as a handle; and (c) adhering the reinforced film to the heat-shrinkable packaging film, thereby providing a reinforced handle that adheres to a heat-shrinkable packaging film and is located beneath the heat-shrinkable packaging, thereby improving the aesthetics of the enclosed object;wherein the handle is configured to bear a load of up to 12 kg, and is characterized by a film thickness between 10 µ and 40 µ and a film width between 20 mm and 80 mm.;

[0024] In some cases, bonding is achieved by heat sealing, ultrasonic welding, solvent welding, gluing, pressure-sensitive adhesives, laser welding or radio frequency welding, including any combination thereof.

[0025] It is therefore a further object of the present invention to disclose a method for heat shrink packaging of an object that requires this, comprising: (a) Providing a reinforced handle that adheres to a heat-shrinkable packaging film; (b) wrapping the item with the heat-shrinkable packaging adhered to the reinforced handle, thereby obtaining a wrapped item; (c) heating the wrapped item, causing the reusable handle film adhered to the heat-shrinkable packaging film to shrink around the shape of the item, thereby securely and firmly enclosing the item, thereby obtaining a packaged item; the handle is positioned below the heat-shrinkable packaging, thereby improving the aesthetics of the packaged product; and wherein the handle is configured to support a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0026] In some embodiments, the bonding is either an inline bonding process or an offline bonding process.

[0027] The present invention therefore relates to disclosing an object encased in a reusable heat-shrinkable package, comprising (a) an object; and (b) a reusable heat-shrinkable package; wherein the reusable heat-shrinkable package comprises: (i) a heat-shrinkable package film configured to enclose an object and mechanically secure the object when heat is applied; and (ii) a reinforced film that adheres to the heat-shrinkable package film and serves as a handle; wherein the handle is arranged below the heat-shrinkable package and thereby improves the aesthetics of the packaged product; wherein the handle is configured to support a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0028] The object of the present invention is therefore to introduce a packaging system in which a reinforcing film for the handle is bonded to a shrink film, thus ensuring high mechanical strength and the required load-bearing capacity without the need for additional handle components. This system reduces manufacturing costs while maintaining structural integrity and recyclability. Because the shrink film and the reinforcing film contract synchronously, the system improves ergonomic properties for reliable and comfortable transport of the packaged goods, thereby enhancing both packaging efficiency and sustainability.

[0029] The subject matter currently disclosed may be better understood by reading the following detailed description of non-restrictive exemplary embodiments with reference to the drawings.

[0030] The dimensions of the components and features shown in the illustrations were chosen for clarity and are not necessarily to scale. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to identical and similar parts. Fig. Figure 1 presents a perspective view of a packaged set of bottles, illustrating (1A) a reinforced film integrated into a heat-shrinkable packaging film and (1B) a reinforced film handle integrated into the packaging film, and showing its application around a group of containers according to some embodiments of the present invention. DETAILED DESCRIPTION OF PREFERRED EXECUTION FORMS

[0031] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as they are commonly understood by a person skilled in the art in the field to which the invention relates. Although methods and materials similar or equivalent to those described herein may be used in practice or in testing embodiments of the invention, exemplary methods and / or materials are described below. In case of any discrepancies, the patent specification, including its definitions, shall prevail. Furthermore, the materials, methods, and examples are for illustrative purposes only and are not to be understood as limiting.

[0032] Further embodiments and the full scope of applicability of the present invention will become apparent from the detailed description below. However, it should be understood that while the detailed description and specific examples indicate preferred embodiments of the invention, they are given for illustrative purposes only, as various changes and modifications within the spirit and scope of the invention will be apparent to the person skilled in the art from this detailed description.

[0033] According to one aspect of the present invention, a reinforced film is provided which is configured to adhere to a heat-shrinkable packaging film and serves as a handle (20) of a packaged product; the handle (25) is located below the heat-shrinkable packaging (30), thereby improving the aesthetics of the packaged product.

[0034] In some embodiments, the handle is configured to support a load of up to 12 kg, up to 11 kg, up to 10 kg, or up to 9 kg, including any range in between. Each possibility constitutes a separate embodiment of the present invention.

[0035] In some embodiments, the handle is characterized by a layer thickness between 10 µm and 40 µm, between 10 µm and 35 µm, between 10 µm and 30 µm, between 15 µm and 40 µm, between 15 µm and 35 µm, between 20 µm and 40 µm, between 20 µm and 35 µm, or between 15 µm and 30 µm, including all values ​​or ranges in between. Each possibility constitutes a separate embodiment of the present invention.

[0036] In some embodiments, the handle is characterized by a film width between 20 mm and 80 mm, between 20 mm and 75 mm, between 20 mm and 70 mm, between 25 mm and 80 mm, between 25 mm and 75 mm, or between 25 mm and 70 mm, including all values ​​or ranges in between. Each possibility constitutes a separate embodiment of the present invention.

[0037] Those skilled in the art know that a common solution for handles in the packaging industry involves first packaging the goods and then attaching a handle. The handle typically consists of a polypropylene film, which provides structural strength and serves as a printable surface; an adhesive layer, which attaches the handle to the packaging; and a paper layer, which ensures a comfortable grip while preventing contact with the adhesive. The total thickness is approximately 50 micrometers, and its manufacture requires costly processes such as printing, applying adhesive, and laminating with paper for protection and durability. In contrast, the present invention provides an integrated reinforced film handle characterized by a reduced thickness in the range of 10 to 40 micrometers.Despite its reduced thickness, the handle's reinforced structure allows it to withstand loads of up to 12 kg, offering both material savings and mechanical strength. Integrating the handle makes it possible to (a) eliminate printing on the handle and instead print on the outer film, thus reducing costs, or (ii) print directly on the handle. Because the print is enclosed between the handle and the shrink film, it is protected, eliminating the need for transparency or additional protective measures while still allowing the use of PCR or more cost-effective materials. In some embodiments, the print is applied to the handle, the outer film, or both.

[0038] In some embodiments, the reinforced handle eliminates the need for the high transparency currently required for the handle, thus enabling the use of recycled materials. Furthermore, the integrated reinforced film handle of the present invention and the packaging film are made from the same material and can be easily recycled.

[0039] In some embodiments, the reinforced film is an MDO (Machine Direction Orientation) film designed to increase the strength of the film.

[0040] The term “Machine Direction Orientation (MDO)” refers to a process used in the production of films, especially plastic films, in which the material is stretched or oriented in the same direction – the so-called machine direction – as it passes through the production line.

[0041] In some embodiments, the reinforced handle and the heat-shrinkable packaging film shrink synchronously during a heat-shrinking process to ensure uniform shrinkage and structural integrity. Those skilled in the art know that synchronous shrinkage of the handle and shrink film is crucial for secure, visually appealing, and functional packaging. It prevents warping, misalignment, or creasing, thus ensuring a professional appearance while maintaining structural integrity. Proper shrinkage also ensures that the handle remains firmly and reliably attached during transport and handling. Overall, synchronized shrinkage improves durability, aesthetics, and efficiency, thereby enhancing both the consumer experience and the efficiency of the supply chain.

[0042] In some embodiments, the reinforced film complies with Regulation (EU) 2025 / 40. In some embodiments, the reinforced handle film of the present invention is a 95% recyclable Class A material. In some embodiments, the recyclable heat-shrinkable packaging film of the present invention is also recyclable. As used herein, the term “Class A – 95% recyclable material” means that at least 95% of the material can be recycled to qualify as a Class A material and comply with EU Regulation 2025 / 40.

[0043] In some embodiments, the reinforced handle film of the present invention consists of grade B materials that are 80% recyclable. Non-limiting examples of reinforced films include, among others, low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), polyolefin (PO), polypropylene, polyamide, including any combination thereof, or a derivative thereof.

[0044] In some embodiments, the reinforced grip film is characterized by an elongation at break that lies between 10% and 120%, between 20% and 120%, between 30% and 120%, between 10% and 110%, between 10% and 100%, or between 20% and 100%, including all values ​​or ranges in between. Each possibility constitutes a separate embodiment of the present invention.

[0045] In some embodiments, the reinforced grip film is characterized by a tensile strength between 80 MPa and 250 MPa, between 80 MPa and 225 MPa, between 80 MPa and 200 MPa, between 100 MPa and 250 MPa, or between 100 MPa and 200 MPa, including all values ​​or ranges in between. Each possibility constitutes a separate embodiment of the present invention.

[0046] In some embodiments, the present invention enables the use of PCR materials.

[0047] In some embodiments, the reinforced grip film also incorporates recycled post-consumer (PCR) material. In some embodiments, the reinforced grip film also incorporates at least 10%, at least 15%, at least 20%, at least 25%, at least 30% PCR material, based on the weight of the handle. Experts know that the addition of PCR material contributes to sustainability goals, reduces environmental impact, and enables a circular economy, while maintaining the required mechanical properties of the handle, such as tensile strength, durability, and resilience.

[0048] Those skilled in the art will appreciate that the present invention not only supports the use of PCR materials but also addresses the general aesthetic challenges associated with their use. PCR materials are inherently often less transparent and can have an inconsistent appearance, which could detract from the visual appeal of the packaging, particularly when used in external components such as handles. In the current solution, however, the handle is integrated beneath the outer packaging layer, which is typically printed. This effectively conceals the PCR material and preserves the overall appearance of the packaging while simultaneously utilizing recycled content.In cases where the packaging is not printed, positioning the handle inside the packaging offers a clear advantage: the consumer can easily identify its location, allowing for faster access. This design not only contributes to sustainability by incorporating recycled materials but also enhances the user experience by ensuring functionality without compromising aesthetics.

[0049] In some embodiments, the reinforced film is a food-grade material. The term "food-grade material" as used here refers to a material that can safely touch or hold food without contaminating it or posing a health risk. Generally, the material has been (I) tested and approved to not release any harmful chemicals, toxins, or particles into the food, (ii) not alter the taste, smell, or quality of the food, and (iii) comply with the regulations and standards of health and safety authorities, such as the Food and Drug Administration (FDA) or the European Food Safety Authority (EFSA).

[0050] According to one aspect of the present invention, a reusable heat-shrinkable packaging film (RHSP film) is provided, comprising a heat-shrinkable packaging film configured to enclose an object and mechanically secure the object when heat is applied, and which adheres to the reinforced film disclosed herein; the reinforced film serves as a handle, and the handle is located below the heat-shrinkable packaging; thereby improving the aesthetics of the enclosed object.

[0051] The person skilled in the art knows that the thickness of the reinforced film is at most 40 µm, since the RHSP film is rolled up after the two films are bonded and fed into a shrink-wrapping machine. The reinforced film is only bonded to a portion of the heat-shrinkable packaging film, with the RHSP film having a different thickness depending on its location on the film. This difference is caused by the fact that the handle is only bonded to a specific point on the shrink wrap where the handle is to be attached.

[0052] In some embodiments, RHSP is characterized by mechanical strength equal to or greater than that of a standard heat shrink film. The term "standard heat shrink film" as used here refers to a plastic film that shrinks tightly to an object when heat is applied, forming a secure protective layer. Heat shrink packaging films are typically made from polymers such as PVC, polyethylene (PE), or POF. They are widely used in the food and beverage, electronics, pharmaceutical, and consumer goods industries. Shrink packaging effectively protects objects of various shapes and sizes during storage, handling, and presentation.

[0053] The term "film" as used here refers to a thin, usually flexible layer or sheet of material whose thickness is significantly less than its length and width. Films are typically made of plastics, metals, or other polymers and are used in a wide variety of applications due to their light weight, flexibility, and versatility. The term "layer" refers to a single thickness of material.

[0054] The term "heat-shrinkable packaging film" refers to a type of plastic film, usually made of PE, but also of PVC or other thermoplastic materials. The film is designed to tightly wrap and secure a group of six bottles when heat is applied. PE film is inexpensive and can be printed or produced in various colors. During manufacturing, it is stretched and aligned so that it shrinks tightly around the product when heated.

[0055] Non-restrictive examples of heat-shrinkable packaging include, but are not limited to, polyethylene terephthalate glycol, linear low-density polyethylene, low-density polyethylene, medium-density polyethylene (MDPE), polypropylene, polylactic acid, including any combination or derivative thereof.

[0056] The term "derivative" here refers to a material, compound or product that has been derived from a base material by chemical, physical or mechanical modification or by combination with other substances to improve or change its properties.

[0057] Non-restrictive examples of LLDPE derivatives include LLDPE copolymers, metallocene LLDPE, LLDPE mixtures, LLDPE compounds, cross-linked polyethylene and LLDPE / ethylene vinyl acetate (EVA) mixtures.

[0058] The terms "reinforced handle film," "reinforced film," or "handle" are used synonymously here and refer to a film characterized by a tensile strength between 80 MPa and 250 MPa in the machine direction. A reinforced film is distinguished by its increased mechanical strength, durability, tear or puncture resistance, and in some cases, its flexibility or heat resistance, compared to an unreinforced film. Reinforced films are frequently used in applications requiring thin but strong material, such as packaging, construction, medical devices, and protective coatings.

[0059] In some embodiments, the bonding agent is selected from the group consisting of temperature seals, solvent-based adhesives, water-based adhesives, pressure-sensitive adhesives, extrusion coating and lamination, ultrasonic welding or hot melt adhesives, static electricity and any combination thereof.

[0060] In some cases, the bonding is done by ultrasonic welding.

[0061] In some embodiments, the reinforced film or the heat-shrinkable packaging film, or both, also contain additives. Non-limiting examples of additives include, but are not limited to, microperforations, stabilizers, plasticizers, antioxidants, fillers, antistatic agents, lubricants, barrier enhancers, foaming agents, biodegradable additives, surfactants, or antimicrobial agents, including any combination thereof.

[0062] The term "microperforation" used here refers to tiny, evenly distributed holes in the packaging film. These small holes allow for controlled airflow and moisture exchange, which can be essential for packaging applications requiring ventilation or pressure equalization. Experts know that the presence of microperforations in the RSHP (Reinforced Heat-Shrinkable Packaging Film) can control the shrink rate of both the reinforced film and the heat-shrinkable packaging film, helping both films shrink synchronously during a heat-shrinking process and ensuring uniform shrinkage and structural integrity. Furthermore, the microperforations allow the film to conform more evenly to the package contents, promoting consistent shrinkage rates for both films.The micro-perforations can also serve to relieve air pressure during the shrinking process in order to prevent possible air inclusions and to ensure a tighter fit over an uneven object.

[0063] In some embodiments, the reinforced film includes an anti-slip additive that modifies the surface structure of the handle, thus improving the user's grip during handling.

[0064] In some embodiments, the reinforced film serves as a handle after the heat-shrinking process. In some embodiments, the handle is an integrated handle.

[0065] In some embodiments, the handle is a concealed handle. In some embodiments, the shrink wrap also includes a slit designed to guide and facilitate the creation of a handle opening.

[0066] The following is a perspective view of a packaged set of bottles in Fig. . Fig. Figure 1 shows an integrated, reinforced handle (20) within the packaging film (30), according to some embodiments of the present invention. Fig. shows an integrated reinforced handle (25) located under a heat-shrinkable packaging film with a slit (27), according to other embodiments of the present invention.

[0067] In some embodiments, the incision consists of perforation lines, cut holes, or both. A person skilled in the art would assume that the incision ensures a clean and controlled tear, guarantees a consistent shape and strength of the handle, and provides flexibility by keeping the handle intact during transport and storage, while allowing it to be easily opened by the user when needed.

[0068] In some designs, the handle is configured to distribute the weight of the load evenly and reduce the potential pressure on the user's hand.

[0069] Experts know that an even distribution of the load and a reduction in potential pressure are achieved through an ergonomically shaped handle that conforms to the natural grip of the hand. This design ensures that the handle size is characterized by a diameter suitable for the user's hand size, thus increasing comfort and ease of use. In some embodiments, the reinforced handle also incorporates contoured shapes, soft or padded materials, and adjustable components to further optimize grip and reduce strain during use. In some embodiments, a handle effectively softens pressure points and promotes a more comfortable experience for the user.

[0070] In some embodiments, the reinforced grip film includes a coating layer. Those skilled in the art know that the type of coating influences the grip properties. For example, certain coatings can reduce the friction of the grip, while others can improve the user's feel at the interface.

[0071] Another object of the present invention is the disclosure of a method for producing a reusable heat-shrinkable packaging film, comprising: (a) Providing a heat-shrinkable packaging film configured to enclose and surround an object and mechanically secure the object when heat is applied; (b) Providing a reinforced film (the reinforced film disclosed above) configured to act as a handle; and (c) Adhering the reinforced film to the heat-shrinkable packaging film, thereby obtaining a reinforced handle that adheres to a heat-shrinkable packaging film and is positioned below the heat-shrinkable packaging, thereby improving the aesthetics of the enclosed object; wherein the handle is configured to support a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0072] According to a further aspect of the present invention, a method for producing a reusable heat-shrinkable packaging film (RHSP) is provided, comprising: (i) providing a heat-shrinkable packaging film configured to enclose an object and mechanically secure the object when heat is applied; (ii) providing the reinforced film disclosed herein, configured to act as a handle; and (iii) bonding the reinforced film to the heat-shrinkable packaging film, thereby obtaining a reinforced handle that adheres to and is located beneath the heat-shrinkable packaging, thus improving the aesthetics of the enclosed object.

[0073] According to a further aspect of the present invention, a method for heat-shrink packaging an object requiring this is provided, comprising: (i) providing a reinforced handle that adheres to a heat-shrinkable packaging film; (ii) encasing the object with the heat-shrinkable packaging adhered to the reinforced handle, thereby obtaining an encased object; (iii) heating the encased object, whereby the reusable handle film adhering to the heat-shrinkable packaging film shrinks around the shape of the object, thereby securely and firmly enclosing the object; and (iv) cooling the enclosed object, thereby obtaining a packaged object; the handle is located below the heat-shrinkable packaging, thereby improving the aesthetics of the packaged product.and wherein the handle is configured to bear a load of up to 12 kg, and is characterized by a film thickness between 10µ and 40µ and a film width between 20 mm and 80 mm.;

[0074] According to a further aspect of the present invention, a method for producing a reusable heat-shrinkable package for an item requiring one is provided, comprising: (i) providing a recyclable reinforced film configured to serve as a handle; (ii) providing a heat-shrinkable package film; and (iii) bonding the recyclable reinforced film to the heat-shrinkable package film, thereby obtaining a recyclable heat-shrinkable package with a handle arranged below the heat-shrinkable package, thus improving the aesthetics of the packaged item; and wherein the handle is configured to support a load of up to 12 kg, and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0075] In some embodiments, the bonding is either an inline bonding process or an offline bonding process. The term "inline bonding process" as used here refers to a method for processing materials or components directly within a continuous production line without the need for separation. The term "offline bonding process" as used here refers to a process that takes place outside the main continuous production line. In this case, the bonding or gluing occurs in a separate step, usually after the primary manufacturing or production steps and not during the material or product flow through the production line.

[0076] Non-restrictive examples of inline bonding processes include, but are not limited to, thermal bonding, heat shrinking, solvent bonding, ultrasonic welding, electrostatic bonding, sealing or simple attachment, including any combination thereof.

[0077] Non-restrictive examples of offline bonding processes include, but are not limited to, laminating, manual gluing, pressure bonding, hot pressing, pressure-sensitive adhesives, solvent bonding, adhesive curing, laser welding or laminating, including any combination thereof.

[0078] According to a further aspect of the present invention, an item is provided which is enclosed in a reusable heat-shrinkable package comprising (i) an item and (ii) a reusable heat-shrinkable package; wherein the reusable heat-shrinkable package (i) is a heat-shrinkable package film configured to enclose an item and mechanically secure the item when heat is applied, and a reinforced film that adheres to the heat-shrinkable package film and serves as a handle; wherein the handle is arranged below the heat-shrinkable package and thereby improves the aesthetics of the packaged product; and wherein the handle is configured to support a load of up to 12 kg and is characterized by a film thickness between 10 µm and 40 µm and a film width between 20 mm and 80 mm.

[0079] Experts know that shrink wrap is used to seal, protect, and bundle various products. Examples of shrink wrap can be found in the consumer goods and retail industries, the food and beverage industry, various pharmaceutical and medical fields, as well as in manufacturing and hardware. As used herein, the term "object" refers to any item that needs to be sealed, protected, or bundled.

[0080] In Fig. Figure 2 shows a heat-shrinkable packaging system comprising a packaging film 30 and an integrated reinforced film 25 beneath the packaging. The packaging film 30 appears to envelop and secure a series of bottles. The reinforced film 25 provides an aesthetically pleasing integration while maintaining structural integrity. The cutout in element (27) reveals the handle, which facilitates lifting the packaged bottles. Fig. Figure 3 shows a heat-shrinkable packaging system with several bottles secured in a packaging film 30. The packaging film 30 encases the bottles and is equipped with a reinforced film handle 20. The reinforced handle 20 is designed to facilitate carrying the packaging while remaining unobtrusive due to its integration into the packaging film 30.

[0081] The reinforced handle 20 is located near the top of the bottles, ensuring balanced weight distribution during handling. Integrating the reinforced handle 20 into the packaging film 30 ensures that the handle remains concealed beneath the film, thus improving the overall aesthetics of the packaging.
