At present, there are many packaging products in the market, and the most common one is plastic packaging barrels. At present, there are more and more types of plastic packaging barrels, and the pressure of competition is also increasing. Plastic barrel manufacturers seize their own brands and product characteristics to occupy the market. The following editor of Wholesale Pressed biscuit tin will talk about the performance test knowledge of the packing barrel!
1. Anti-corrosion test: When testing its anti-corrosion properties, the packing barrel is placed in a corrosive chemical, and then the temperature of the corrosive chemical is maintained at 75 degrees Celsius and immersed for 48 hours. There should be no presence in the barrel. Cracking, blistering or deformation occurs.

2. Resistance to cold and heat: working temperature: -30℃～50℃. Destructive test: -30℃～110℃ (softening temperature). Detailed description: The plastic bucket will be refrigerated at -18°C for 12 hours, and then an iron pole with a diameter of 65mm and a weight of 5kg is used to hit the injection point of the plastic trash can three times from a height of 1m. The plastic bucket After the low temperature test, the barrel body should not be cracked or deformed.
3. High temperature resistance test: The plastic bucket will be put into a room for 3 days. The temperature of the room is maintained at 90-95 degrees Celsius. After cooling, the surface of the plastic bucket should not be damaged, blistered or deformed. The moisture absorption of the raw materials used is less than 0.01 to ensure that the box structure will not become brittle or deformed.
4. Description of barrel wall thickness: In terms of engineering plastics, barrel wall thickness is not the main reason for the toughness of the barrel. The raw materials used, the anti-ultraviolet component, the mold and the injection molding equipment are all related. For most customers, the quality of plastic barrels does not depend on the wall thickness but whether the plastic barrels can pass different test conditions. The wall thickness depends on the design of each mold.
The above is the editor of Wholesale Pressed biscuit tin introducing the performance test knowledge of the packing barrel.
