What are Dow LLDPE Resin - 2645G
In the rapidly developing packaging film market, raw materials are not only the foundation for shaping but also the core factors influencing the performance, compliance and processing efficiency of the products. Dow LLDPE 2645G resin, as a linear low-density polyethylene (LLDPE) that meets food contact safety standards, is becoming a reliable material choice in multiple fields such as flexible packaging and industrial films due to its balanced mechanical properties and process adaptability.
01 | Material Highlights: Starting from the formula, multiple performance advantages are constructed
LLDPE 2645G resin adopts a clean formula without anti-slip agents and molding AIDS, taking into account both film performance and application safety. Its characteristics are mainly reflected in:
High toughness and tear resistance coexist: Under only 51μm film, the tear strength reaches 720g (MD) /1000g (TD), and the tensile elongation at break exceeds 600%, which can significantly enhance the anti-damage ability of the packaging film during transportation and use.
Strong processing adaptability: Whether it is blow molding or extrusion film production, its melt index of 0.90g /10min brings good fluidity and stable bubble control, and is suitable for various film production line speeds and die head structures.
Outstanding thermal stability: The melting temperature is as high as 120°C, and the Vicat softening temperature is 107°C, ensuring that the film formation process is not prone to deformation and enhancing the tolerance of the processing window.
Food contact compliance: In line with mainstream food packaging regulations, there is no need to worry about the residue of migratory substances. It is suitable for the development of packaging films for various refrigerated and frozen foods.
02 | Optical Performance: Balancing visual effect and practicality
For brand packaging, both visual communication power and functional protection power are indispensable. LLDPE resin 2645G is provided:
・Glossiness 63 (45°) : It has a certain reflective effect and enhances the texture of the packaging appearance.
・12% haze: Strikes a balance between visual obstruction and content recognition, suitable for frozen packaging and some daily chemical soft film requirements.
This visual attribute is particularly suitable for products that have moderate requirements for transparency while also needing a certain degree of softening of the visual effect.

04 | Typical Application fields: From food films to industrial lamination
Thanks to its comprehensive performance, LLDPE 2645G resin is suitable for the following various film applications:
Frozen/refrigerated food packaging film: resistant to low-temperature impact and not prone to cracking
Industrial films: such as transport inner lining films and base materials for composite films
Commercial shopping bags/roll bags: Scenarios where a high balance between strength and cost is required
Daily chemical packaging film: Suitable for packaging requirements such as laundry detergent bags and cosmetic soft packages that require strong protection for the contents
In addition, this resin can also be used as a blending modification base material for other polyolefin materials to enhance overall toughness and tear strength.
05 | Reasons for Choice: A versatile LLDPE resin
Dow LLDPE 2645G resin is not merely a "general-purpose" LLDPE. With its excellent strength, thermal stability and clean composition design, it has become a "safe choice" for film factories when dealing with multi-specification orders:
・The processing performance is stable, reducing the frequency of equipment adjustment
・Performance balance reduces the complexity of raw material replacement in different application scenarios
・The formula is clean and in line with the market trend for products with "low migration" and "few additives"
