Description

Technical Field

[0001] This invention relates to the field of convenient medical care bags, specifically to a convenient hand care bag. Background Technology

[0002] Existing medical and elderly care convenience bags have poor stability and heat resistance, and the texture of their inner lining that comes into contact with the skin needs to be improved. Summary of the Invention

[0003] To address the above problems, this invention provides a convenient hand care bag: A convenient hand care bag includes an outer cover and an inner lining disposed inside the outer cover. The outer cover includes a surface layer and an inner layer. The inner layer is an ultra-low temperature PE film, and the inner lining is made of non-woven fabric. The inner lining and the inner layer are connected by ultrasonic roller heat sealing.

[0004] Preferably, the surface layer is composed of the following raw materials by weight percentage: 50%-60% medium-density polyethylene (MDPE), 20%-30% modified metallocene 1520, 10%-25% LLDPE (Sinopec linear low-density polyethylene DFDA-7042), and 10%-25% LLDPE (linear low-density polyethylene 2045G).

[0005] Preferably, the inner layer is composed of the following raw materials by weight percentage: modified metallocene 1520 50-60%, linear polyethylene DFDA-7042 25-30%, and LLDPE linear low-density polyethylene 2045G 10%-25%.

[0006] A method for preparing a PE film includes the following steps: mixing the raw materials for the inner layer and the raw materials for the outer layer separately, and then adding them into two different inlets of a two-layer co-extrusion blown film mill, and obtaining a PE film through co-extrusion blown film; wherein, the screw temperature inside the inner layer raw material inlet of the two-layer co-extrusion blown film mill is 140-150℃, the screw temperature inside the outer layer raw material inlet is 160-170℃, and the film outlet temperature of the two-layer co-extrusion blown film mill is 160-170℃.

[0007] Preferably, the inner layer includes a first layer and a second layer of the same material. The first layer is fixedly connected to the inner surface of the outer layer. The surface of the second layer is provided with multiple air vents. Both the second layer and the lining are elastic. Multiple circumferentially arranged adjusting airbags are fixedly connected between the first layer and the second layer. The adjusting airbags extend in the length direction relative to the outer layer. Each adjusting airbag is interconnected. An air vent channel connecting the air vents to the outside is provided between adjacent adjusting airbags. A ventilation pipe for connecting adjacent adjusting airbags is provided between the adjusting airbags. The ventilation pipe is arranged in a ring at one end of the outer layer and is connected to a valve.

[0008] Preferably, a plurality of fixing plates are provided between the first layer and the second layer, which interlock with the ventilation channel. The surface of the fixing plates is provided with a plurality of strip-shaped ventilation slots, and the lower end of the fixing plates forms a limiting fit with the inner side of the ventilation pipe. The fixing plates can be used for fracture positioning and fixation of the arm, increasing the functionality of this product.

[0009] Preferably, in the outer film formed by the first layer and the surface layer, the thickness of the first layer accounts for 45-55% of the total thickness of the PE film.

[0010] Beneficial effects: First, the composition of this medical and health care packaging material is as follows: the outer layer uses stretched MDPE, and in terms of production process, it is combined with domestic Sinopec linear 7042, imported linear 2045 and metallocene 1520, etc. After blown film forming, preheating, stretching and cooling process, its printing stability is improved by 40% and heat resistance is improved by 50%. The inner layer uses ultra-low temperature PE, so that its heat sealing temperature is below 95 degrees, reducing the stretching and misalignment of the pattern caused by high temperature during bag making. The two layers of PE as the main single material are combined together to form the main structure of the packaging. Second: The inner lining of this invention is made of PE low-temperature material ultra-soft texture meltblown nonwoven fabric, which has good water absorption, moisturizing and anti-slip properties and ultra-soft texture, making the skin feel comfortable and improving the affinity between the medical solution and the skin. At the same time, during heat sealing, the nonwoven fabric can be fused with the inner PE layer to form a tight seal. Third, the present invention uses an ultrasonic roller device to fix the inner lining and inner PE layer. The ultrasonic fixation is used to improve the fixation that cannot be hot-pressed and to reduce the impact on the appearance. After the inner lining is fixed, it enters the edge insertion, bottom folding, edge sealing, hot pressing, and die cutting. The bag body is smooth and has no burrs or sharp corners.

[0016] The following is in conjunction with the appendix Figure 1-4The present invention will be further described with reference to Examples 1-2.

[0017] Example 1: As Figure 1 As shown, a convenient hand care bag includes an outer shell and an inner lining disposed within the outer shell. The outer shell comprises a surface layer and an inner layer. The inner layer is an ultra-low temperature PE film, and the inner lining is made of non-woven fabric. The inner lining and the inner layer are connected by ultrasonic roller heat sealing. The surface layer is composed of the following raw materials by weight percentage: medium-density polyethylene (MDPE) 50%-60%, modified metallocene 1520 20%-30%, LLDPE (Sinopec linear low-density polyethylene DFDA-7042) 10%-25%, and LLDPE (linear low-density polyethylene 2045G) 10%-25%. The inner layer is composed of the following raw materials by weight percentage: modified metallocene 1520 50-60%, linear polyethylene DFDA-7042 25-30%, and LLDPE (linear low-density polyethylene 2045G) 10%-25%. The thickness of the inner layer accounts for 45-55% of the total thickness of the PE film. The inner layer in Example 1 is a single-layer structure, while the inner layer in Example 2 below is a double-layer structure made of the same material.

[0018] Example 2: As Figure 2 As shown, a convenient hand care bag includes an outer shell and an inner lining disposed within the outer shell. The outer shell comprises a surface layer and an inner layer. The inner layer is an ultra-low temperature PE film, and the inner lining is made of non-woven fabric. The inner lining and the inner layer are connected by ultrasonic roller heat sealing. The surface layer is composed of the following raw materials by weight percentage: medium-density polyethylene (MDPE) 50%-60%, modified metallocene 1520 20%-30%, LLDPE (Sinopec linear low-density polyethylene DFDA-7042) 10%-25%, and LLDPE (linear low-density polyethylene 2045G) 10%-25%. The inner layer is composed of the following raw materials by weight percentage: modified metallocene 1520 50-60%, linear polyethylene DFDA-7042 25-30%, and LLDPE (linear low-density polyethylene 2045G) 10%-25%.

[0019] like Figure 3As shown, the inner layer comprises a first layer and a second layer of the same material. The first layer is fixedly connected to the inner surface of the outer layer, and the surface of the second layer has multiple vent holes. The ultra-low temperature PE film used in the inner layer has a certain degree of elasticity, and its elasticity can be further enhanced by adding appropriate additives to meet requirements. The lining needs to be made of elastic non-woven fabric. Multiple circumferentially arranged adjusting airbags are fixedly connected between the first and second layers. The adjusting airbags extend relative to the length of the outer layer, and each adjusting airbag is interconnected. Ventilation channels connecting the vent holes to the outside are provided between adjacent adjusting airbags. Ventilation pipes for connecting adjacent adjusting airbags are provided between the adjusting airbags. The ventilation pipes are annularly arranged at one end of the outer layer and connected to valves. Multiple fixing plates that interlock with the ventilation channels are provided between the first and second layers. The surface of the fixing plates has multiple strip-shaped ventilation slots, and the lower end of the fixing plates forms a limiting fit with the inner side of the ventilation pipes. The fixing plates can be used for fracture positioning and fixation of the arm, increasing the functionality of this product. In the outer film formed by the first layer and the surface layer, the thickness of the first layer accounts for 45-55% of the total thickness of the PE film.

[0020] The overall structure of this invention is tubular, primarily adaptable to the arm. If needed, it can also be designed as a shoe or glove to fit the foot and hand. Users can directly slip the invention over their arm, where the inner lining provides corresponding protection. Furthermore, by controlling the gas volume within the airbag, the size of the inner lining can be freely adjusted to fit arms of different sizes, offering greater flexibility. The use of a fixation plate further enhances its bone positioning function, allowing for use in existing fracture localization techniques.

[0021] A method for preparing a PE film includes the following steps: mixing the raw materials for the inner layer and the raw materials for the outer layer separately, and then adding them into two different inlets of a two-layer co-extrusion blown film mill, and obtaining a PE film through co-extrusion blown film; wherein, the screw temperature inside the inner layer raw material inlet of the two-layer co-extrusion blown film mill is 140-150℃, the screw temperature inside the outer layer raw material inlet is 160-170℃, and the film outlet temperature of the two-layer co-extrusion blown film mill is 160-170℃.
