Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to stretch films, in particular to a ribbon stretch stretch film. Background Art
[0002] Ribbon stretch wrap is a packaging material with stretch properties, and its surface may be printed with colorful stripes or patterns, similar to ribbons.
[0003] Stretch film has some disadvantages when stretched. If it is stretched too much or the stretching force is uneven, it will easily break and thus the packaging will fail. Some stretch films have poor retraction properties after stretching and cannot maintain the stretched state, which affects the tightness and stability of the packaging. The stretching process may also expose the problem of uneven thickness, causing some parts to be overstretched and thinned and easy to break. Uneven stretching will cause stress to concentrate at certain points, reducing the overall strength and durability. In addition, stretching may also affect the viscosity, resulting in insufficient viscosity after packaging items and unable to effectively fix the items, which is more inconvenient.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] The utility model provides Figure 1-2 The illustrated ribbon stretch wrap film comprises a base layer 1, a reinforcing layer 2 is provided on the top of the base layer 1, an elastic layer 3 is provided on the top of the reinforcing layer 2, a thickness uniformizing layer 4 is provided on the top of the elastic layer 3, a stress dispersion layer 5 is provided on the top of the thickness uniformizing layer 4, a ribbon layer 6 is provided on the top of the stress dispersion layer 5, and a viscosity adjustment layer 7 is provided on the bottom end of the base layer 1. The reinforcing layer 2 is made of a specific material and distributed in a specific shape to improve the strength and tensile resistance. The elastic layer 3 makes the film more elastic and adaptable, and can effectively cope with the packaging of items of different shapes and sizes. The thickness uniformizing layer 4 ensures uniform thickness during stretching, reducing the situation where local areas are too thin and easy to break. The stress dispersion layer 5 can buffer and disperse stress, thereby improving the durability and damage resistance of the wrap film. The viscosity adjustment layer 7 adjusts the viscosity according to the stretching to ensure stable packaging and effective fixation of items.
[0019] Specifically, the reinforcement layer 2 is made of one of glass fiber, aramid fiber, and polyester fiber. Glass fiber significantly improves the tensile strength and tear resistance of the stretch film, maintaining good performance even in high-temperature environments at a low cost, making it economical. Aramid fiber imparts extremely high strength and abrasion resistance to the stretch film. Aramid fiber is lightweight, providing reinforcement without significantly increasing the weight of the stretch film. It also exhibits excellent chemical resistance and adaptability to a variety of chemical environments. Polyester fiber, with its excellent elastic recovery properties, allows the stretch film to return to its original shape after stretching. It also exhibits excellent weather resistance, is not easily affected by climatic conditions, and offers stable performance, making it easy to composite and manufacture with other materials. The reinforcement layer 2 has a mesh structure that provides uniform reinforcement in all directions, ensuring excellent strength and tensile resistance in all stretching directions. It effectively disperses stress generated during stretching, preventing stress concentration in localized areas, thereby reducing the risk of film rupture. This helps maintain the stability of the stretch film structure, reduces deformation and distortion, and enhances the film's durability, extending its service life and adapting it to more complex and demanding packaging environments.
[0020] Furthermore, the elastic layer 3 is made of either TPU or TPE. Choosing TPU as the material, due to its excellent elasticity and tensile properties, gives the product excellent resilience and flexibility, allowing it to quickly return to its original shape even after frequent stretching and deformation. TPU also exhibits excellent wear resistance, oil resistance, and chemical corrosion resistance, which greatly enhances the product's durability and adaptability in various complex environments, maintaining good performance regardless of friction, oil stains, or chemical corrosion. Furthermore, TPU's high strength and toughness make the elastic layer 3 less susceptible to rupture or damage during use, effectively extending the product's service life. The advantages of using TPE are also significant, with its soft touch and good elasticity, providing a comfortable experience for the user. In terms of processing, TPE exhibits excellent performance and is easy to form and manufacture, helping to improve production efficiency and reduce production costs. Furthermore, TPE is recyclable, meeting current environmental protection needs and helping to reduce resource waste and environmental pollution. Whether TPU or TPE is used for elastic layer 3, both materials offer excellent elasticity and durability, better meeting diverse application scenarios and user needs. Elastic layer 3 has a uniform, film-like structure, ensuring consistent elastic properties across all areas of the stretch film. This means that when stretching and wrapping an item, the same elastic response is achieved regardless of where force is applied on the film, providing a more stable and reliable packaging experience and effectively preventing loose wrapping or damage to the item due to localized lack of elasticity.
[0021] Furthermore, the material of the thickness equalization layer 4 is polyvinyl alcohol, which has good film-forming properties and can form a uniform, continuous, and smooth film layer. This helps to ensure the quality consistency of the entire thickness equalization layer 4, thereby better playing its role in regulating and balancing the overall thickness. Secondly, polyvinyl alcohol has excellent water solubility. In certain specific application scenarios or subsequent processing, if this thickness equalization layer 4 needs to be removed, its water solubility can be used to achieve this conveniently, efficiently, and environmentally friendly. Furthermore, polyvinyl alcohol has good adhesive properties and can be effectively combined with other layers to enhance the adhesion between the layers and improve the structural stability and integrity of the stretch film. In addition, polyvinyl alcohol also has certain flexibility and tensile properties. While playing a role in thickness equalization, it will not significantly affect the overall elasticity and flexibility of the stretch film, ensuring the flexibility and adaptability of the stretch film during use. Finally, polyvinyl alcohol is a relatively economical material with a relatively low cost, which helps to control the production cost of the stretch film while providing good performance. The thickness uniformization layer 4 is a uniform film-like structure. The uniform film-like structure can ensure that the thickness of the entire stretch film remains highly consistent. This means that when using the stretch film for packaging, regardless of the shape and size of the wrapped items, they can be uniformly and reliably protected, avoiding the problem of insufficient protection or excessive packaging due to local uneven thickness.
[0022] Furthermore, the material of the stress dispersion layer 5 is one of polyethylene foam and elastic rubber. If the material is polyethylene foam, it has good buffering performance, can effectively absorb and disperse external impact stress, protect the packaged items, and is light in weight, has certain thermal insulation performance, and can also reduce production costs; if the material is elastic rubber, it has excellent elasticity and resilience, quickly returns to its original shape after being subjected to stress, and its performance remains good after repeated use. It has good flexibility and can adapt to different items. It is wear-resistant and weather-resistant, and has good compatibility with other layers, enhancing the overall structural stability. The stress dispersion layer 5 is a continuous film-like structure. The continuous film-like structure can ensure that the stress is evenly distributed over the entire layer, avoiding local areas of stress concentration, thereby more effectively protecting the packaged items from damage. This continuous structure has better integrity and stability, is not prone to problems such as breakage or delamination, and ensures the long-term effectiveness of the stress dispersion function.
[0023] Furthermore, the material of the ribbon layer 6 is one of polyethylene, polypropylene and polyester. The ribbon layer 6 is a uniform film structure. By using ribbon layers 6 of different colors, the visual appeal and aesthetics of the stretch film can be increased, making the stretch film more eye-catching and unique in appearance, and standing out among many packaging materials, increasing recognition, and facilitating the distinction between packages of different batches, different uses or different contents.
[0024] Furthermore, the viscosity adjustment layer 7 uses an acrylic adhesive. Acrylic adhesive has excellent bonding strength, which can ensure a close fit between the stretch film and the packaged object, providing reliable fixation and protection. Secondly, it has good weather resistance and can maintain stable viscosity under different environmental conditions without being significantly affected by factors such as temperature and humidity. Moreover, this type of adhesive has a certain balance between initial viscosity and sustained viscosity, which can not only quickly adhere in the initial stage but also maintain the bonding effect for a long time. In addition, acrylic adhesive has good transparency and will not affect the appearance and visibility of the stretch film. At the same time, it also has low toxicity and irritation, and is relatively friendly to the human body and the environment.
[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
