Product Overview
DFDA 7042 is a high-performance Linear Low-Density Polyethylene (LLDPE) resin manufactured by Wanhua Chemical Group Co., Ltd. Produced using advanced coordination polymerization technology with butene as the comonomer, this product features a linear molecular structure without long-chain branching, which fundamentally distinguishes it from conventional Low-Density Polyethylene (LDPE). DFDA 7042 is widely recognized in the industry for its excellent tensile strength, toughness, superior puncture resistance, and tear strength, while maintaining high gloss and transparency. This grade is specifically designed for blown film and cast film processing, making it suitable for various film products including agricultural films, industrial packaging films, daily-use films, frozen food films, laminated films, and garment films, meeting the diverse requirements of different terminal markets.

Logistics & Supply Standards
DFDA 7042 is supplied in paper bags with a standard packaging specification of 25 kg/bag. The product is in the form of white pellets and is classified as non-hazardous. During transportation, to ensure product quality and safety, it is recommended to load it independently rather than mixing it with other goods in the same container. We maintain sufficient stock to meet the immediate shipping needs for regular orders. Standard delivery lead times depend on specific trade terms (e.g., EXW, FOB, CIF) and the destination; regular orders will be arranged for shipment according to the agreed timeframe upon confirmation. It is recommended to store the product in a ventilated, dry, and dark area, avoiding direct sunlight and contact with strong oxidizing agents.
Compliance & Quality Commitment
DFDA 7042 complies with multiple international and industry standards, ensuring its safety and stability in various demanding applications. Regarding food contact safety, the product meets the requirements of the U.S. Food and Drug Administration (FDA) 21 CFR 177.1520, making it suitable for the production of polyolefin products in direct contact with food. Regarding chemical compliance, the product meets the requirements of the EU REACH Regulation (EC 1907/2006) and the RoHS Directive on the restriction of hazardous substances.
We are committed to providing a complete compliance documentation package with the shipment, including but not limited to: Technical Data Sheet (TDS), Material Safety Data Sheet (MSDS), and Certificate of Analysis (COA). This product possesses complete batch traceability, with key performance indicators from raw material procurement and production to final shipment all being verifiable, ensuring consistent quality for every batch.
Sustainability & ESG Statement
As an LLDPE base resin, DFDA 7042 exhibits favorable environmental properties. The product is a recyclable thermoplastic; the resin itself is non-toxic, odorless, and tasteless, and no halogenated or other harmful substances are involved in the processing, aligning with current industrial “3R” principles (Reduce, Reuse, Recycle).
The resin supports regeneration and recycling within appropriate recovery systems, helping downstream customers improve the green profile of their packaging. By optimizing material formulations, DFDA 7042 can assist terminal applications in achieving a lower environmental footprint. We recommend that users evaluate and adopt corresponding recycling solutions in line with specific product application scenarios and local waste management policies to uphold sustainability commitments.
FAQs (Frequently Asked Questions)
Q1: Does DFDA 7042 require drying before processing?
DFDA 7042 is a linear low-density polyethylene with low hygroscopicity. Under normal storage conditions (ventilated, dry, and dark), the resin generally does not require pre-drying before processing. However, if the packaging has been opened or exposed to high-humidity environments for an extended period, it is recommended to dry the material before processing to remove surface moisture and prevent defects such as gel spots or bubbles in the film. For specific drying temperature and time parameters, please refer to the processing guidelines in the provided Technical Data Sheet (TDS).
Q2: What are the minimum order quantity (MOQ) and sample policy for DFDA 7042?
The MOQ depends on the specific trade terms (e.g., EXW, FOB, CIF) and delivery method, with regular bulk orders measured in metric tons. Regarding sample requests, we can provide appropriate quantities for testing and evaluation based on customer needs; please contact our sales representatives to confirm specific sample policies and procedures.
Q3: What is the difference between DFDA 7042 and similar LLDPE grades (such as DFDA 7042K) in terms of application selection?
DFDA 7042 is a butene-copolymer LLDPE specifically designed for blown and cast film processes, offering a balanced performance in tensile strength, toughness, and gloss, suitable for general thin-film applications such as agricultural mulch, greenhouse films, daily-use films, cling films, liner films, and industrial packaging. Different manufacturers or similar grades with different suffixes (such as DFDA 7042K) may have subtle differences in additive formulations (e.g., anti-blocking agents, slip agents) and melt flow indices. We recommend that users consult the respective Technical Data Sheets (TDS) and evaluate the material against their specific processing equipment and end-use requirements before selection, validating compatibility through trial testing when necessary.
