2. Global Compliance & Certifications
For factories exporting packaging to highly regulated markets such as Europe and North America, the compliance of raw materials is also within the scope of customer evaluation. Sinopec HHM5502LW has obtained full certification and is suitable for highly regulated applications, including food contact packaging and medical packaging:
- Food Grade Standards: Fully compliant with FDA (USA) and GB9691-1988 (Chinese National Food Grade Standard).
- Chemical & Safety Compliance: Certified BPA-Free, with full compliance under MSDS USA and MSDS EU protocols.
- Environmental & Toxicity Standards: Passes rigorous screening for PAHs, 17P (Phthalates), REACH 138, and RoHS 2.0.
3. Main Applications
Thanks to its excellent flowability and high stability, this type of material is widely used in the packaging industry for extrusion blow molding (EBM) of small to medium-sized hollow products:
- Containers for everyday chemicals: Industrial and household detergent drums, liquid laundry detergent bottles, and shampoo bottles.
- Automotive and industrial fluids: Heavy-duty lubricating oil drums and chemical drums.
- Regulated containers: Food bottles, condiment containers, and pharmaceutical bottles that require strict compliance with food and pharmaceutical regulations.

4. Processing and Molding Guidelines
To minimize waste and achieve optimal surface finish, the HHM5502LW’s ring suspension structure offers the best performance with the following basic thermal parameters:
- Blow Molding Temperature: A temperature of 170 °C is recommended.
- Screw and Cylinder Temperature Profiles: Maintain temperatures in each heating zone between 160 °C and 200 °C.
Note: Depending on the local tropical climate or plant humidity levels, it may be necessary to adjust the cooling cycle and preform inflation rate to avoid variations in wall thickness.
