Abstract
Description
Technical Field
[0001] This utility model relates to the field of material ton bag technology, specifically an environmentally friendly and easy-to-fill material ton bag. Background Technology
[0002] Material ton bags, as the core packaging containers for the transportation and storage of bulk materials (such as grains, chemical raw materials, building aggregates, and feed), are widely used in agricultural production, chemical industry, construction engineering, and logistics warehousing. In agriculture, they are used for centralized storage and transportation of grains such as wheat and corn; in the chemical industry, they are used to load granular or powdered chemical raw materials; and in the construction industry, they are used to transport aggregates such as sand and cement. Their core requirements are "strong load-bearing capacity, convenient loading, and high durability," while also meeting modern environmental protection requirements. However, most current material ton bags are made of non-degradable polyethylene, which pollutes the environment after disposal. Therefore, we propose an environmentally friendly material ton bag that is easy to load. Utility Model Content
[0003] The purpose of this invention is to provide an environmentally friendly and easy-to-fill material ton bag, which has the advantage of being environmentally friendly and solves the problem that most current material ton bags are made of non-degradable polyethylene, which pollutes the environment after disposal.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly and easy-to-fill material ton bag, comprising a bag body, an inlet at the top of the bag body, and hanging straps around the bag body. The bag body includes a wear-resistant layer, a first high-strength layer, an anti-aging layer, a second high-strength layer, and a base material layer. The wear-resistant layer comprises a corn starch-based modified polypropylene woven fabric layer, a flax fiber composite polylactic acid woven fabric layer, and a bamboo fiber modified biodegradable polyethylene film layer.
[0005] Preferably, the corn starch-based modified polypropylene woven fabric layer is located outside the flax fiber composite polylactic acid woven fabric layer, and the flax fiber composite polylactic acid woven fabric layer is located outside the bamboo fiber modified biodegradable polyethylene film layer.
[0006] Preferably, the first high-strength layer is recycled PET woven fabric, and the anti-aging layer is a nano-titanium dioxide modified PLA film.
[0007] Preferably, the second high-strength layer is a hemp fiber composite biodegradable PP woven fabric, and the substrate layer is a biodegradable PE composite film.
[0008] Preferably, the wear-resistant layer is located outside the first high-strength layer, which is located outside the anti-aging layer.
[0009] Preferably, the anti-aging layer is located outside the second high-strength layer, which is located outside the substrate layer.
[0010] Preferably, the wear-resistant layer, the corn starch-based modified polypropylene woven fabric layer, the flax fiber composite polylactic acid woven fabric layer, the bamboo fiber modified biodegradable polyethylene film layer, the first high-strength layer, the anti-aging layer, the second high-strength layer, and the substrate layer are all bonded together by EVA hot melt adhesive.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The outermost wear-resistant layer of the bag body of this utility model is composed of a corn starch-based modified polypropylene woven fabric layer, a flax fiber composite polylactic acid woven fabric layer, and a bamboo fiber modified biodegradable polyethylene film layer. All three layers are biodegradable or modified environmentally friendly materials that can naturally degrade after disposal, completely avoiding white pollution. Among them, the corn starch-based modified polypropylene woven fabric layer has strong wear resistance and can resist friction damage during loading and handling. The flax fiber composite polylactic acid woven fabric layer enhances toughness, and the bamboo fiber modified biodegradable polyethylene film layer improves waterproofness. The first high-strength layer is recycled PET woven fabric, which not only utilizes recycled resources to reduce costs but also strengthens the load-bearing capacity of the bag body. The anti-aging layer is a nano-titanium dioxide modified PLA film, which can resist aging and embrittlement caused by ultraviolet rays. The second high-strength layer is hemp fiber composite biodegradable PP woven fabric, which, together with the biodegradable PE composite film of the base layer, forms a multi-layer support of "wear-resistant - high strength - anti-aging - high strength - base layer".
[0012] 2. The opening size of the feed inlet at the top of the bag body is compatible with common feeding equipment, such as hoppers and conveying pipes. No additional docking accessories are required when loading materials, and materials can quickly enter the bag body to avoid spillage. The hanging straps around the bag body can stably support the weight of the materials. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0017] Example 1: Please see Figure 1-3 As shown, this utility model provides an environmentally friendly and easy-to-fill material ton bag, including a bag body 1, a material inlet 2 at the top of the bag body 1, and hanging straps 3 around the bag body 1. The bag body 1 includes a wear-resistant layer 4, a first high-strength layer 5, an anti-aging layer 6, a second high-strength layer 7, and a base material layer 8. The wear-resistant layer 4 includes a corn starch-based modified polypropylene woven fabric layer 401, a flax fiber composite polylactic acid woven fabric layer 402, and a bamboo fiber modified biodegradable polyethylene film layer 403.
[0018] Preferably, the corn starch-based modified polypropylene woven fabric layer 401 is located outside the flax fiber composite polylactic acid woven fabric layer 402, the flax fiber composite polylactic acid woven fabric layer 402 is located outside the bamboo fiber modified biodegradable polyethylene film layer 403, the first high-strength layer 5 is recycled PET woven fabric, the anti-aging layer 6 is nano-titanium dioxide modified PLA film, the second high-strength layer 7 is hemp fiber composite biodegradable PP woven fabric, the substrate layer 8 is biodegradable PE composite film, the wear-resistant layer 4 is located outside the first high-strength layer 5, the first high-strength layer 5 is located outside the anti-aging layer 6, the anti-aging layer 6 is located outside the second high-strength layer 7, the second high-strength layer 7 is located outside the substrate layer 8, and the wear-resistant layer 4, the corn starch-based modified polypropylene woven fabric layer 401, the flax fiber composite polylactic acid woven fabric layer 402, the bamboo fiber modified biodegradable polyethylene film layer 403, the first high-strength layer 5, the anti-aging layer 6, the second high-strength layer 7 and the substrate layer 8 are all bonded together by EVA hot melt adhesive.
[0019] The outermost abrasion-resistant layer 4 of the bag body 1 in this technical solution consists of a corn starch-based modified polypropylene woven fabric layer 401, a flax fiber composite polylactic acid woven fabric layer 402, and a bamboo fiber modified biodegradable polyethylene film layer 403. All three layers are biodegradable or modified environmentally friendly materials that can naturally degrade after disposal, completely avoiding white pollution. Among them, the corn starch-based modified polypropylene woven fabric layer 401 has strong abrasion resistance and can resist friction damage during loading and handling. The flax fiber composite polylactic acid woven fabric layer 402 enhances toughness, and the bamboo fiber modified biodegradable polyethylene film layer 403 improves waterproofness. The first high-strength layer 5 is made of recycled PET. The woven fabric utilizes recycled resources to reduce costs while enhancing the load-bearing capacity of the bag body 1. The anti-aging layer 6 is a nano-titanium dioxide modified PLA film, which can resist aging and embrittlement caused by ultraviolet rays. The second high-strength layer 7 is a hemp fiber composite biodegradable PP woven fabric, which, together with the substrate layer 8 biodegradable PE composite film, forms a multi-layer support of "wear-resistant-high strength-anti-aging-high strength-substrate". The opening size of the feed port 2 at the top of the bag body 1 is compatible with common feeding equipment, such as hoppers and conveying pipes. No additional docking accessories are required when loading materials, and materials can quickly enter the bag body 1 to avoid spillage. The hanging straps 3 around the bag body 1 can stably support the weight of the materials.
[0020] The working principle of this utility model is as follows: First, the empty bag 1 is suspended on a hoisting device or loading rack by the hanging straps 3 around the bag body 1, ensuring that the bag body 1 remains stable and the top inlet 2 faces upward; then, the discharge end of the feeding device is aligned with the inlet 2, and the feeding device is started. The material enters the bag body 1 through the inlet 2. At this time, the base layer 8 of the bag body 1, the biodegradable PE composite film, serves as the inner layer to prevent material leakage. The second high-strength layer 7, the hemp fiber composite biodegradable PP woven fabric, and the first high-strength layer 5, the recycled PET woven fabric, work together to bear the weight of the material and prevent leakage. The bag body 1 deforms excessively due to the load. During the filling process, the outermost wear-resistant layer 4 of the bag body 1 resists external friction and minor impacts, while the anti-aging layer 6, a nano-titanium dioxide modified PLA film, protects the bag body 1 from the effects of ultraviolet rays in the environment and prevents aging and embrittlement. After the material is filled, the bag body 1 is hoisted to the transport vehicle or storage area by the hanging strap 3. The stability of the multi-layer structure during stacking keeps the bag body 1 in shape and prevents it from tipping over. After use, the discarded bag body 1 can gradually degrade in the natural environment because each layer is made of biodegradable or environmentally friendly material, with no risk of white pollution.
