How to Distinguish PE Material From PP Material

How to distinguish PE material from PP material when purchasing? Aceally has three small ways to quickly differentiate.

1. See the reflection of the box surface
There will be a layer of protective film on the surface of turnover box made of PE material, which has good reflective effect, while the turnover box made of PP material does not have such a film, and the reflective degree is not so bright.

2. Listen to the voice
Gently tap the plastic logistics box with your hands, the sound of PE material logistics box will be loud and crisp, the sound of PP material logistics box will have a soft feeling, the sound is neither crisp nor loud.

3. See resilience
Use your hands to gently extrude the turnover box. The plastic box made of PE material is a little harder, and the recovery speed is relatively slow after extrusion. The box made of PP material can be recovered immediately after extrusion.

The above method only teaches you how to use the physical characteristics of the two materials to identify, not to compare the quality of the two materials, because the turnover boxes made of the two materials have their own advantages and disadvantages. Through high gloss injection molding process, the plastic turnover box is tasteless and nontoxic, and its quality and safety have reached the requirements of national food safety testing standards. It can be used to hold food and is clean and convenient. It is widely used in closed-loop distribution systems such as Dalian lock supermarket, 24-hour convenience store, large distribution center, department store, food processing, etc.
