1. Odor generated by unreacted materials and by-products in the manufacturing process of plastic hollow plates.
2. The peculiar smell produced by thermal decomposition or oxidation of plastic hollow board.
3. Due to the volatilization, dissolution and decomposition of additives, the odor generated by the reaction with the packaging materials.
4. Odor generated by adhesives, printing inks and solvents used for compounding materials.
5. Odor caused by irradiation, etc. The most influential of these factors is the thermal decomposition of plastics, oxidative aging, and the odors generated by additives, binders, etc. There are many types of peculiar odors produced by hollow plates of plastic packaging materials, ranging from sweet to medicinal, burnt, paraffin, and solvent, with complex ingredients. Once the odor is generated, it will contaminate the packaged product, so it is important to find the source and solve it in time.
