Daqing Petrochemical DGDB-6097 (HDPE Blown Film Grade) – High Flow & High Toughness Film Resin
Product Overview
Daqing Petrochemical DGDB-6097 is HDPE resin for blown film. It features high melt flow, balanced stiffness and toughness, and inherent performance to prevent film layers from sticking. It is a widely used grade for general packaging films, including T-shirt bag resin and garbage bag HDPE.Its MFR is 9.0 g/10min. It runs steadily on high-speed blown film lines and produces uniform films with high tear resistance and strong load capacity. No extra slip or anti-block additives are needed.
This is a PetroChina Kunlun product with consistent quality across all batches. COA is available for every batch. It delivers good cost efficiency and supports smooth daily production.

Core Product Advantages
1. High fluidity for high-speed blown film production
This resin has a 9.0 g/10min melt flow rate, so the material flows easily. It extrudes evenly and forms stable films during production. It matches all common high-speed production machines. It raises output, lowers uneven film thickness and reduces faulty products. You can adjust machine settings easily. It also lessens die blockage and crystal spots on films.
2. Balanced hardness and toughness with good mechanical performance
This material has solid hardness and toughness. Its tensile break strength is around 14.4 MPa and elongation at break is 652 %. The finished films resist tearing, piercing and heavy loads well. Its Charpy notched impact strength is 12 kJ/m². This figure is 15–20 % higher than regular HDPE for blown film, whose impact strength is 10 to 12 kJ/m². Products made from this resin do not bend or wear easily and last longer.
3. Built-in anti-stick property to simplify formula and save cost
The resin itself stops film layers from sticking together. You do not need to buy and add extra agents. This makes your production formula simpler and cuts material costs. It also keeps additives from moving out or building up on film surfaces. The films look clean, stay safe, with low haze and high clarity.
4. Basic anti-aging ability for wide use
Its Vicat softening temperature is 125°C. It can stand high heat and will not break or deform during processing. It resists aging well. You can use products indoors for a long time or outdoors for a short time. If products stay outside under sunlight for long periods, mix the resin with UV masterbatch to get better weather resistance.
5. Fits multiple processing methods for more uses
You can use it not only for blown film, but also for injection molding, regular extrusion and blow molding. One single material can make films, injection parts, extruded profiles and hollow containers. Factories can use fewer raw material types and manage stock more easily.
Main Application Fields
Packaging Films: Shopping bags, T-shirt bags, garbage bags, food packaging films, heavy industrial packaging films, equipment inner liners, shrink filmsAgricultural Films: Short-term agricultural films (add UV masterbatch for long outdoor use)Daily Plastic Products: Plastic turnover boxes, bottle caps, container shells, common injection plastic goodsExtruded Products: Flat yarn, woven bags, geotextiles, ropesHollow Products: Small chemical drums, daily blow-molded bottles
Frequently Asked Questions
Q1: Can DGDB-6097 make packaging for food?A: This pure HDPE resin meets GB 4806.6-2016 National Food Safety Standard - Plastic Resins for Food Contact. You can use it directly for food bags that hold non-oily and non-high-temperature food. If you pack hot or oily food, run migration tests based on your final products. Ask for batch COA for filing.
Q2: Can DGDB-6097 mix with LLDPE, LDPE and other polyethylene materials?A: You can mix them properly. Mix with LLDPE to make films softer and harder to tear. Mix with LDPE to improve material flow and film surface shine. Do small batch tests and adjust machine settings before large-scale production.
Q3: What is the minimum order quantity and packaging standard?A: Each bag weighs 25 kg. The minimum order is one bag. We provide partial truck and full truck delivery to support sample tests and mass orders.
Q4: How to store this resin and what is its shelf life?A: Keep it in dry, cool and well-ventilated warehouses. Keep it away from sunlight, rain, high heat, open fire and harmful chemicals. When sealed and stored properly, the shelf life is 24 months. Please use goods in the order you receive them.
Q5: Is it hard to use this resin for injection molding and blow molding besides blown film?A: It is easy to process and fits most machines. Follow the recommended temperature range, and you can get stable finished goods with no big changes to your equipment. You can make different products flexibly.
