Wow, after I went to listen to the master of the plastic bottle manufacturer yesterday, I realized that the knowledge about plastic bottles is so extensive! ! Do you know what secrets are hidden in plastic bottles? Haha, let me tell you
First: It turns out that the molding of plastic bottles is not formed by solution as I imagined, but by blow molding, injection molding, and injection of materials one by one. The process of forming the final plastic product by stretch blowing
Second: There is usually a triangular symbol under the bottom of the plastic bottle, which contains the number of ~. This is really a lot of knowledge for the editor. Let me tell you clearly:
, the numbers are like the small bottles of mineral water we usually drink, which represent disposable plastic bottles that cannot be reused and will become toxic if used for a long time
, the numbers are generally made of cleaning bottles It is recommended not to reuse it. If you want to use it, you need to clean it carefully because this kind of container is generally difficult to clean and will leave behind the previously filled detergent
. Digital is currently rarely used to make packaging containers such as plastic doors and oil pipes. It is commonly used some materials that are difficult to burn and extinguish immediately after leaving the fire. Fire will emit a pungent smell
. Numbers are generally more common in membranes and cannot produce harmful substances when exposed to fire
. Numbers are the only material that can The material is used for baking in the microwave oven, but the lid generally does not use materials, so if you want to bake it, it is recommended to take off the lid
. The numbers are generally made of materials, such as bowls of instant noodles and fast food boxes, which are made of heat-resistant materials. But it is not suitable to be placed in the microwave to avoid releasing chemicals. We also try to avoid using fast food boxes for meals
. In terms of numbers, our kettle is made of this material
I hope the editor of Yunhui Packaging Sharing can help everyone. Everyone must pay attention to these things in life, especially mineral water bottles. Many people like to reuse them or use them to fill oil. This is absolutely not allowed
