High Optical Transparency: With a haze of < 7% and gloss of > 90, the resulting film exhibits high transparency and excellent luster. It clearly displays the original appearance of the packaged product, enhancing the aesthetic grade of the packaging. It is particularly suitable for food and daily necessities that require high visual appeal to strengthen market competitiveness.
Excellent Processability: The pellets offer good fluidity and superior slip properties, ensuring smooth blow molding without issues like sticking to the mold or film breakage. This significantly improves production efficiency and reduces processing waste. It is compatible with various conventional film blowing equipment, reducing the difficulty of equipment commissioning.
Good Mechanical Strength: It combines excellent tensile strength with high elongation at break. The film is flexible yet tear-resistant and impact-resistant, providing effective protection for packaged goods and reducing loss during transportation and storage. The stable tensile modulus ensures consistent dimensions after molding, improving the overall texture of the packaging.
Outstanding Chemical Stability: It resists corrosion from many common chemicals at room temperature, making it suitable for packaging food, cosmetics, industrial parts, and more. It also provides a good seal, effectively blocking water vapor and dust to extend the shelf life of products.
High Cost-Effectiveness & Versatility: As a mature grade mass-produced by SINOPEC Maoming Petrochemical, the quality is stable with minimal batch-to-batch variation and reliable supply. it can be used alone or blended with materials like LLDPE to meet general needs across multiple industries, offering cost-performance that exceeds similar products.
As a general-purpose film-grade LDPE, SINOPEC Maoming LDPE 2426K is widely used in packaging, agriculture, and industrial fields:
Packaging Industry (Core Application) The preferred material for packaging films, used to produce various high-transparency films, including food packaging (snack bags, fresh-keeping bags), daily necessities packaging (cosmetic tubes, toiletry packaging), and industrial product packaging (small part bags, electronic protective films). Its high transparency displays product details, while its sealing and tear resistance provide protection. It also meets food-grade requirements, being safe and non-toxic. It is also used for heat-shrink films, composite films, and frozen food packaging.
Agriculture Suitable for producing agricultural films, including mulch films, greenhouse films, and insect nets. Its good flexibility and weather resistance help in heat preservation, moisture retention, and pest control, improving crop yield and quality. The resulting film is tough and durable enough to withstand complex field environments, reducing planting costs for farmers.
Industrial Sector Used to produce cable sheaths, pipes, and insulating materials. Its good electrical insulation and corrosion resistance meet the rigorous demands of industrial scenarios, ensuring the safe operation of electrical equipment and pipelines. It can also be used for pipe coatings and equipment linings to improve wear and corrosion resistance.
Other Fields Used for foaming products, daily-use hoses, etc. It can be blended with LLDPE to optimize material properties for heavy-duty packaging films or medical packaging (subject to meeting relevant standards).
Q1: What is the processing temperature range for SINOPEC Maoming LDPE 2426K? Which processes is it suitable for?
A1: The primary processing method is blow molding, with a recommended melt temperature range of 150-210°C and a mold temperature suggested at 20-40°C. Proper pre-drying is recommended before processing to ensure the optical performance and transparency of the film. Due to its good fluidity, it is also suitable for some extrusion molding processes. Specific parameters can be fine-tuned based on equipment and product specifications; referring to the official TDS or consulting technical personnel is recommended.
Q2: Does this product comply with food-grade standards? Can it be used for food packaging?
A2: The production of SINOPEC Maoming LDPE 2426K strictly follows the quality control standards of SINOPEC Maoming Petrochemical. It is odorless, free of harmful impurities, and meets food-grade requirements. It can be safely used in food packaging (such as snack bags and fresh-keeping bags). We recommend that customers verify compliance based on specific food types and relevant packaging standards during actual application.
Q3: What are the precautions for the packaging, storage, and transportation of SINOPEC Maoming LDPE 2426K?
A3: Packaging: Packaged in inner-lined polypropylene woven bags, 25kg net weight per bag, with secure sealing to prevent impurities and moisture. Storage: Should be stored in a ventilated, dry, and cool warehouse away from fire, heat sources, and direct sunlight. Outdoor stacking is prohibited to avoid performance degradation. Transportation: Must be protected from sunlight and rain. It should not be mixed with sand, soil, scrap metal, or toxic, corrosive, and flammable materials to ensure product integrity.
Q4: What are the core advantages of this product compared to other LDPE grades? Can it be blended with LLDPE?
A4: The core advantage lies in its comprehensive performance of “high transparency + easy processing + high cost-effectiveness.” Compared to other LDPE grades, it has lower haze and higher gloss, with better slip properties and less risk of film breakage during processing. Being mass-produced by SINOPEC Maoming, it offers stable quality and supply. Additionally, it can be blended with LLDPE to further optimize tensile strength and tear resistance for expanded application scenarios. Blending ratios can be adjusted according to specific needs.
