Abstract
The utility model discloses a medical waste plastic packaging material is kept apart to height includes PE layer, linear low density polyethylene layer, adhesive layer one, EVOH layer, adhesive layer two and metallocene polyethylene heat-seal layer through crowded combination altogether in proper order. Through detecting the proof, the utility model discloses a high isolation medical waste plastic packaging material has excellent strength properties and heat sealability, can prevent effectively that medical waste from leaking and diffusing, has high barrier properties moreover, can effectively keep apart outside oxygen and steam and see through to effectively prevent that the inside germ of medical waste from breeding.
Description
Technical Field
The utility model relates to the field of packaging technology, concretely relates to packaging material is kept apart to multilayer height for medical waste packing.
Background
The medical waste package can prevent the medical waste from leaking and diffusing in the process of passing through and prevent the secondary pollution caused by the growth of germs, and is convenient for storage and transportation of the medical waste. The medical waste packaging material who uses at present mainly is Polyethylene (PE) wrapping bag, membrane, and in the use, the ubiquitous can not realize effective isolation of medical waste and can not effectively prevent the problem of breeding of the inside germ of medical waste.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a medical waste plastic packaging material is kept apart to height, has high strength, high barrier property, can effectively prevent medical waste to leak and inside germ multiplying.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a high-isolation medical waste plastic packaging material sequentially comprises a PE layer, a linear low-density polyethylene layer, a first adhesive layer, an EVOH layer, a second adhesive layer and a metallocene polyethylene heat-sealing layer.
Further, the thickness of the PE layer was 14 μm.
Further, the thickness of the linear low density polyethylene layer was 13.5 μm.
Further, the thickness of each of the first adhesive layer and the second adhesive layer was 5 μm.
Further, the thickness of the EVOH layer was 5 μm.
Further, the thickness of the metallocene polyethylene heat-sealing layer is 14 μm.
Further, a colored warning layer is arranged between the second adhesive layer and the metallocene polyethylene heat-sealing layer.
Further, the thickness of the colored warning layer is 13.5 μm.
The beneficial effects of the utility model reside in that: through detecting the proof, the utility model discloses a high isolation medical waste plastic packaging material has excellent strength properties and heat sealability, effectively prevents that medical waste from leaking and diffusing, has high barrier properties moreover, can effective separation outside oxygen and steam to effectively prevent that the inside germ of medical waste from breeding and diffusing, prevent secondary pollution.

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
This example provides a high-isolation medical waste plastic packaging material, as shown in fig. 1, which comprises a PE layer 1, a linear low-density polyethylene layer 2, a first adhesive layer 3, an EVOH layer 4, a second adhesive layer 5 and a metallocene polyethylene heat-seal layer 6 in this order.
In this example, the PE layer 1 is 14 μm thick. The PE layer may be printed after corona treatment.
In this example, the linear low density polyethylene layer 2 has a thickness of 13.5 μm.
In this example, the adhesive layer one 3 and the adhesive layer two 5 each have a thickness of 5 μm and are used for bonding the linear low density polyethylene layer 2 and the EVOH layer 4.
In this example, the thickness of the EVOH layer 4 was 5 μm. The EVOH layer can be arranged to make the packaging material have high barrier property.
In this example, the thickness of the metallocene polyethylene heat-seal layer 6 was 14 μm.
In this embodiment, a colored warning layer 7 is disposed between the second adhesive layer 5 and the metallocene polyethylene heat-sealing layer 6. The colored warning layer is made of color master. The colored warning layer can be yellow.
Further, in the present embodiment, the thickness of the colored warning layer 7 is 13.5 μm.
In practical application, the packaging material can be used as a packaging film or a packaging bag. The multi-layer co-extrusion composite film is formed through multi-layer co-extrusion, a clamping cylinder film is manufactured through a clamping device in the film blowing process, and then printing and bag making are carried out.
The performance data of the plastic packaging material for high-isolation medical waste of the embodiment is as follows:
tensile strength (transverse, longitudinal): 28 MPa; the dart impact mass is more than 150 g; heat seal strength: 14N/15 mm; oxygen permeability less than or equal to 5cm3/(m224 h.0.1mpa); the water vapor permeability is less than or equal to 6 g/(m)2.24h)。
It can be seen that the medical waste plastic packaging material is kept apart to height of this embodiment has excellent strength properties and heat sealability, effectively prevents that medical waste from leaking and diffusing, has high barrier properties moreover, can effectively separation outside oxygen and steam to effectively prevent that the inside germ of medical waste from breeding and diffusing, prevent secondary pollution.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
