What are the advantages and disadvantages of plastic packaging materials?
First of all, we must say that the biggest feature of plastic packaging materials is light quality and good mechanical properties. For many goods which require long-distance transportation, it can reduce the weight of transportation and facilitate transportation. This is incomparable to glass and metal materials.
Disadvantages of plastic packaging materials:For single individual resin especially monomer polyethylene, when they are selected for production of plastic packaging materials, if the content is too high, that is to reach a certain concentration, it is easy to be absorbed by the packaging of food, so as to produce certain harm to human body, therefore, for some plastic packaging materials they are not, widely used in food packaging. In addition, plastic packaging, as well as strength, hardness is not as good as metal, high material, poor heat resistance, material aging and other characteristics, these are unavoidable shortcomings of plastic packaging materials.Said so much, I believe that the advantages of plastic packaging materials have a basic understanding, here Xiaobian plastic Kushi recommends that in future food packaging, if there is a high demand for fresh, or try to avoid the plastic package!
Have to mention here is that the plastic packaging materials of good health, for those of the pure polymer resin, plastic packaging can be said to be almost no toxicity, when we have food packaging, can be assured of the application.
Secondly, the plastic material has a very suitable barrier and permeability, you know, in plastic packaging, there is gas barrier packaging. Moisture proof packaging, waterproof packaging, and all kinds of fresh fruit packaging. These are plastic packaging to meet the respiratory effects of fresh ingredients. Again, the optical properties of plastic packaging is very good, because the plastic packaging materials can be made transparent, so when it is made of packaging containers, for which we see the contents of the indirect effect of crystal clear, very good promotion way.
