1. Odors produced by unreacted reactants and by-products in the manufacturing process of plastic hollow plates.

2. Abnormal odor caused by thermal decomposition or oxidation of hollow plastic sheet.

3. The odour produced by the reaction with packaging materials due to the volatilization, dissolution and decomposition of additives.

4. Odors produced by bonding agent, hollow sheet price printing ink and solvent used in material composite.

5. Abnormal odor caused by irradiation, etc. Among these factors, the biggest impact is the thermal decomposition of plastics, oxidative aging and the addition of additives, adhesives and other odors.
