Carton packaging and plastic packaging are familiar to everyone and occupy a heavy position in the packaging industry. In terms of cost, carton packaging is higher and plastic packaging is relatively low, but carton packaging is recyclable and has less pollution to the environment. In foreign supermarkets, plastic packaging bags have basically been withdrawn, and recyclable cartons and cartons are usually selected for packaging, because cartons and cartons can be recycled and reused, which has less pollution to the environment.
Therefore, although the cost is high, carton packaging is usually selected. The biggest disadvantage of carton packaging is poor waterproof. These are exactly the advantages of plastic packaging. Therefore, if we want to have a broader market for carton packaging, we must find ways to overcome these disadvantages. It can be predicted that the future packaging industry will be an era in which the raw materials who take the lead in breaking through this bottleneck will occupy the commanding height of the whole packaging market. Plastic packaging will not withdraw from the market for the time being, but it is only a matter of time for it to go off the historical stage compared with carton packaging. Carton production will not decline because of plastic packaging. It will continue to shine in the packaging industry with the development of technology.
First of all, it has to be said that the biggest feature of plastic packaging materials is light weight and good mechanical performance. For many goods that need long-distance transportation, it can reduce the transportation weight and facilitate transportation.
Secondly, plastic materials have 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-keeping packaging for fresh-keeping fruits. These are plastic packages that are extended to meet the breathing function of fresh food materials. Thirdly, the optical performance of plastic packaging is very good. Because plastic packaging materials can be made transparent, when it is made into packaging containers, we can see the contents clearly. This indirect way of promotion has a very good effect. It must be mentioned here that the hygiene of plastic packaging materials is good. For those pure polymer resins, plastic packaging is almost non-toxic. When we want to package food, we can safely apply it. Disadvantages of plastic packaging materials: for individual resin monomers, especially monomer polyethylene, when they are selected for the production of plastic packaging materials, if the content is too high, that is, when it reaches a certain concentration, it is easy to be absorbed by the food in the package, resulting in certain harm to the human body. Therefore, for some plastic packaging materials, They are not commonly used in food packaging.
In addition, plastic packaging has the characteristics of lower strength and hardness than metal and other materials, poor heat resistance and easy aging of materials, which are unavoidable shortcomings of plastic packaging materials. Having said so much, I believe you have a basic understanding of the advantages and disadvantages of plastic packaging materials. Xiaobian suggests that in the future, if you have high requirements for freshness in the packaging of food and other things, you'd better try to avoid plastic packaging!
Plastic has existed for many years, which is closely related to people's life. It also exists in a large number in the building materials industry. It is also an important building material. The emergence of plastic packaging provides great convenience for people's life, but it pollutes the environment. In recent years, carton packaging has become increasingly popular. Simple packaging, personalized patterns and less environmental pollution have been welcomed by people.
