As we all know,plastics will be damaged if not disposed of.However,plastics are also indispensable in our life.Different types of plastic equipment (film blowers) and different plastic products make different plastic technologies available in our life.
In plastic packaging,there is a high probability of damage.Why do you say so?
1:High density polyethylene,not easy to clean completely,not suitable for making water cup,etc.
2:Polyethylene terephthalate can not be used for high temperature water and acid-base drinks.
3:Polyvinyl chloride,with low heat resistance,can release harmful substances during high-temperature differentiation,and is not suitable for packaging food.
4:Acrylonitrile styrene resin,with high safety,high transparency,resistance to falling,but poor durability.
5:Plastic products made of polystyrene shall not be used in the environment of high temperature,strong acid and strong alkali.
6:Polypropylene,only plastic box that can be put into microwave oven.
