Hdpe 7000f

HDPE 7000F is a specialized film grade resin. You must verify the Melt Flow Index (MFI), typically ranging between 0.04 to 0.06 g/10 min (at 190°C/2.16kg), and a Density of approximately 0.950 to 0.954 g/cm³. Ensure the supplier provides a Technical Data Sheet (TDS) confirming high tensile strength and excellent dart impact resistance, which are critical for thin-film applications like T-shirt bags and shopping bags.

Since this material is frequently used for food packaging, it must comply with FDA (U.S. Food and Drug Administration) or EU Food Contact regulations (EC No 1935/2004). Additionally, ensure the product meets REACH and RoHS standards for chemical safety. Always request a Certificate of Analysis (COA) for every batch to ensure consistency in polymer quality.

HDPE 7000F is favored for its excellent processability and bubble stability during blown film extrusion. It allows for the production of ultra-thin films (down to 6-7 microns) without frequent film breaks. Buyers should confirm the resin's molecular weight distribution, as a broader distribution typically enhances melt strength, reducing scrap rates in high-speed production lines.

This grade is primarily used for high-strength grocery bags, garbage liners, and industrial packaging. Due to its stiffness and moisture barrier properties, it is also ideal for multi-layer lamination films and heavy-duty sacks. For specialized industrial use, verify if the resin is compatible with blending with LLDPE to improve tear resistance.

The price of HDPE is highly sensitive to crude oil fluctuations and global supply chain disruptions. To mitigate risk, consider long-term supply contracts with price adjustment formulas or utilize hedging strategies. On Made-in-China.com, prioritize Audited Suppliers who offer price validity periods of at least 7-14 days to avoid sudden cost spikes during the procurement process.

Before full payment, hire a third-party inspection agency (like SGS or Intertek) to perform random sampling from the containers. The inspection should focus on packaging integrity (to prevent moisture contamination), batch number consistency, and contamination checks (ensuring no black spots or foreign particles are present in the pellets).

Resin should be shipped in 25kg PE bags or Jumbo bags (1000kg) on pallets with proper shrink-wrapping. During transit and storage, it must be kept in a cool, dry, and well-ventilated warehouse, away from direct sunlight and heat sources, to prevent polymer degradation and oxidative induction issues.

Always use Secured Payment services provided by reputable B2B platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. For large volumes, utilize Letters of Credit (L/C at sight) to protect against non-delivery and ensure that all shipping documents, including the Bill of Lading and Packing List, strictly match the purchase order requirements.
