Plastic Pump Foam Bottle,PE Bottle,PP Bottle Manufactur […]
Plastic Pump Foam Bottle,PE Bottle,PP Bottle Manufacturers are mainly made of materials such as polyethylene or polypropylene and added with various organic solvents. Polyethylene (PET), polyethylene (PE) and polypropylene (PP) are widely used as raw materials in plastic bottles. After adding the corresponding organic solvents, they are heated at high temperature and then blown, blown, or injection molded through plastic molds. Plastic container.
It is mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oils, agricultural veterinary drugs. Plastic bottles are characterized by being difficult to break, low cost, high transparency, and food grade raw materials.
PE = Polyethylene, polyethylene, is the simplest polymer organic compound. It is the most widely used polymer material of PE polyethylene in the world. It is made of ethylene and is divided into high density polyethylene and medium density poly according to density. Ethylene and low density polyethylene. Therefore, PE bottles are made of polyethylene.
Polyethylene is insoluble in water and has little water absorption. For some chemical solvents, such as toluene and acetic acid, it is only slightly soluble at temperatures above 70 ℃ However, the particulate polyethylene may be melted or solidified with a change in temperature between 15℃ and 40℃, and melted when the temperature is raised to absorb heat; when the temperature is lowered, it solidifies and releases heat. And because it has a small amount of water absorption, is not easy to be wet, and has insulating properties, it is a good building material.
PE and PET are very different, PET is very transparent and PE is opaque or has poor transparency.
Second: look at the bottle mouth PET bottle wall is very neat and clean, PE bottle mouth inside the wall will not work. And the thread is quite obvious Third: look at the bottom PET bottle has a dot at the bottom and a line at the bottom of the PE.
