Embodiment 1

[0039] see Figure 1-5, the present invention provides a technical solution: an environment-friendly and degradable fresh-keeping film preparation device, comprising a preparation main body 4, an installation part 6 is arranged on the top of the right outer wall of the preparation main body 4, and a preparation Device 5, the control panel 3 is fixedly connected to the middle position of the front top of the preparation main body 4, the left outer wall of the preparation main body 4 is located on both sides of the preparation device 5, and adjustment rollers 2 are arranged, and the bottom of the left outer wall of the preparation main body 5 is fixedly connected with Collection shelf 1.

[0040] Wherein, the preparation device 5 includes a control top cover 51, the bottom two sides of the control top cover 51 are fixedly connected with outer partitions 52, and the outer partition 52 is provided with an adjustment mechanism 53 at the middle position near the bottom of one side o...

Embodiment 2

[0045] see Figure 1-5 , on the basis of Embodiment 1, the present invention provides a technical solution: a method for preparing an environmentally friendly and degradable plastic wrap, step 1: prepare raw materials for processing plastic wrap, mix different raw materials and add them to the inside of the device, and mix the first The film that occurs is fixedly wound on the collecting rack 1;

[0046] Step 2: Preheat the raw material and observe the formation process of the discharge by adjusting the opening and closing of the top cover 51. The connection between the support plate 54 and the placement mechanism 55 ensures that the adjustment mechanism 53 is inserted into the interior of the placement mechanism 55, resulting in cooling or heating. gas;

[0047] Step 3: The protective casing 532 and the cold air intensifier 534 realize a small-scale circulation, and use compressed air to inflate while hot, and at the same time use cold air to cool to increase the transparenc...

Abstract

The invention discloses an environment-friendly degradable preservative film and preparation method thereof, and relates to the technical field of preservative films. The film comprises a preparation main body, a mounting part is arranged at the top of the outer wall of the right side of the preparation main body, preparation devices are fixedly connected to the tops of the inner walls of the two sides of the preparation main body, a control panel is fixedly connected to the middle position of the top of the front face of the preparation main body, adjusting rollers are arranged at the positions, located on the two sides of the preparation devices, of the outer wall of the left side of the preparation main body, and a collecting frame is fixedly connected to the bottom of the outer wall of the left side of the preparation main body. According to the environment-friendly degradable preservative film and the preparation method thereof, the tension force of the surface can be further adjusted, the integrity of the film can be conveniently protected, the incomplete processing film caused by non-uniform mixing and the damage of parts during adjustment are effectively avoided, the extrusion stability of the preservative film is further improved, the consistency of the thickness of the preservative film is ensured, and the balance of production raw materials of the preservative film can be ensured.

Description

technical field [0001] The invention relates to the technical field of plastic wrap, in particular to an environmentally friendly and degradable plastic wrap and a preparation method thereof. Background technique [0002] At present, commonly used food preservation films are mostly made of the following materials: polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC). The above-mentioned packaging materials have problems such as poor safety and single functionality, and lack Degradability, easy to cause environmental pollution after being discarded, can no longer meet people's requirements for safety, health and ecological environmental protection. As people pay more and more attention to food safety and environmental awareness, packaging materials with high safety and degradable functions have become a research hotspot. However, the plastic wrap is not easy to degrade after use, which leads to pollution of the living environment. It is prone to breakage during us...
