Daqing 2420D LDPE Blown Film Resin Purchasing Guide | High-Clarity Domestic LDPE Selection Parameters & Tips
Good stable LDPE pellets make clear packing film and farm greenhouse film well. Many buyers only look at low raw material prices when buying. This seems to save money but causes many production issues. Low-quality LDPE has weak melt strength. Wide-blown film machines will have collapsed film bubbles. Factories have to slow down the machine speed. Total output becomes lower. Cheap LDPE also has many impurities. It creates fish eyes and crystal spots on film. The finished film has high haze. Printing looks dim. These goods cannot meet medium and high-end order rules. Besides, cheap LDPE cannot resist aging well. Its heat seal effect is poor. Farm film cracks easily under sunlight. Packing bags often leak, and factories waste many finished goods. When choosing LDPE, stable film bubbles, low haze, weather resistance, and steady stock are more important than a single price. Daqing 2420D LDPE is a domestic high-pressure blown film resin with good cost performance. It runs steadily for small test batches and large mass production. Below are its strong points against the common cheap LDPE.
Many film factory owners hold wrong ideas. They think all high-pressure LDPE works the same. Cheap types can finish normal production. Low-cost LDPE uses rough polymerization methods. Factories mix recycled plastic inside. Its molecular weight is distributed unevenly. Film bubbles shake badly at high machine speed. Machines cannot run at full capacity. Simple filtering leaves many black dots and impurities. This material only fits low-end goods like trash bags and simple inner lining film. Daqing 2420D LDPE comes from Daqing Petrochemical's steady tubular high-pressure production line. It is 100% new pellets with a long-chain structure. It has strong melt strength. All blown film machines form neat bubbles and even film thickness. It stops bubble sagging and film breaking. Multi-step precise filtering keeps film haze below 8%, tested by GB/T 2410. The film lets light pass through easily and looks shiny. Factory-built-in anti-oxidation additives extend farm film service life. It meets food contact rules. It is a steady domestic LDPE to replace imported resin for medium and high-end packing and farm film.

Daqing 2420D LDPE fits many production uses. It makes supermarket fresh bags and clear shopping bags. It's good clarity removes the need to mix imported resin. It works for greenhouse film and ground covering farm film. Strong melt strength fits wide-width production and resists aging well. It makes an industrial moisture-proof inner film with tough texture and steady heat seal. Users can mix it with LLDPE to cut material cost and lift overall film quality.
Core Purchasing Tips
Do not only chase a low single price. Machine stop time, defective film, and customer returns bring higher total cost.
Do not only check the haze value. Melt strength, same quality across batches, and stable supply are also necessary.
Do not only choose imported plastic. Daqing 2420D LDPE can replace the most common imported LDPE with steady performance.
