Embodiment example 1

[0013] An antibacterial fresh-keeping film containing a glass carrier silver ion antibacterial agent is composed of 95% polyethylene and 5% antibacterial polyethylene masterbatch.

[0014] The manufacturing method is to add 5 kg of antibacterial polyethylene masterbatch to 95 kg of polyethylene, then fully mix in a mixer, put the mixed material into a plastic extruder to melt, extrude, and cast to prepare an antibacterial fresh-keeping film.

Embodiment example 2

[0016] An antibacterial fresh-keeping film containing glass carrier silver ion antibacterial agent, its composition is polyethylene 93.9%, antibacterial polyethylene masterbatch 5%, tackifier 1%, edible vegetable oil 0.1%,

[0017] The manufacturing method is to add 0.1 kg of edible vegetable oil to 93.9 kg of polyethylene, then fully mix in a blender, then add 5 kg of antibacterial polyethylene masterbatch and 1 kg of tackifier, continue to mix evenly, and add the mixed material to the plastic The antibacterial fresh-keeping film is prepared by melting extrusion and casting in an extruder.

Embodiment example 3

[0019] An antibacterial fresh-keeping film containing a glass carrier silver ion antibacterial agent, its composition is polyethylene 91.9%, antibacterial polyethylene masterbatch 5%, antifogging agent 3%, edible vegetable oil 0.1%,

[0020] The manufacturing method is to add 0.1 kg of edible vegetable oil to 91.9 kg of polyethylene, and then fully mix it in a blender, then add 5 kg of antibacterial polyethylene masterbatch and 3 kg of anti-fogging agent, continue to mix evenly, and add the mixed material to the plastic The antibacterial fresh-keeping film is prepared by melting extrusion and casting in an extruder.

Abstract

The invention relates to a PE (polyethylene) preservative film containing glass-carrier silver-ion antibacterial agent. An ordinary PE (polyethylene) preservative film contains 0.05 percent to 1 percent of glass-carrier silver-ion antibacterial agent, or further contains one or more of 0.1 percent to 1.5 percent of tackifier, 1 percent to 5 percent of antifogging agent and 0.05 percent to 0.4 percent of edible oil, and the PE in the PE (polyethylene) preservative film is low-density polyethylene or linear low-density polyethylene, or the mixture of low-density polyethylene and linear low-density polyethylene according to a certain proportion. In the preparation technique, the PE polyethylene and the glass-carrier silver-ion antibacterial agent are mixed and pelleted by a single-screw or double-screw extruder, so that antibacterial masterbatches are produced. The extruder then produces the antibacterial preservative film according to the formula by way of casting or film blowing. The product has a high antibacterial property and is durable, and the color cannot be easily changed. In particular, the preservative film has excellent inhibiting and sterilizing effects on bacteria such as colibacillus and staphylococcus aureus.

Description

technical field [0001] The invention relates to a fresh-keeping film containing an antibacterial agent, in particular to a fresh-keeping film containing a glass carrier silver ion antibacterial agent. With the antibacterial agent, the fresh-keeping film has excellent antibacterial properties, long time effect, and the color of the film does not change. technical background [0002] At present, there are ordinary plastic wraps in the domestic market, which do not contain antibacterial agents, especially glass carrier silver ion antibacterial agents. Foreign developed countries have entered the antibacterial era in the 1980s. In recent years, the domestic antibacterial industry has just started to develop, but the technology is mixed, such as: poor antibacterial effect, easy to change color and other problems that need to be improved. With the improvement of living standards, people's requirements for living standards, quality and environment are getting higher and higher, an...
