LDPE typically has a crystallinity of 55–65%, while HDPE ranges from 80–90%. Although PE possesses excellent mechanical processing properties, its inert and non-polar surface results in poor printability, dyeability, hydrophilicity, adhesion, antistatic properties, and compatibility with polar polymers and inorganic fillers. Additionally, its wear resistance, chemical resistance, environmental stress crack resistance, and heat resistance are limited, restricting its application scope. Modification methods are employed to enhance its performance and expand its applications.

April 21, 2025 – Santan, the food and beverage division of Capital A (formerly AirAsia Group), has announced its shift from single-use plastics to biodegradable alternatives, marking a significant step in reducing its environmental footprint. All disposable items onboard, including cups, lids, and cutlery, will now be made from polylactic acid (PLA)—a material derived from renewable resources such as corn and cassava.

Developed by Rightway New Material, PLA offers key advantages over conventional plastics, decomposing at a m

ABS is a flammable material, classified as HB level according to the UL94 standard. When ignited, ABS burns rapidly, releasing large amounts of toxic gases and black smoke, making it unsuitable for many practical applications. With advancements in technology and improvements in quality of life, safety awareness has grown significantly. Both domestic and international industries have imposed strict fire safety and flame-retardant requirements on plastic materials used in automobiles, construction, home appliances, office equipment, and other fields, accompanied by corresponding technical standards and regulations. Therefore, research on flame-retardant ABS holds considerable importance.

There are numerous types of plastics (e.g., PE, PP, PVC), widely used in packaging, construction, healthcare, automotive and other fields, meeting both daily and industrial needs.

When PET is blended with PP, the resulting alloy combines the advantages of both, enhancing overall performance. For example, PET improves PP's heat resistance, while PP reduces PET's moisture sensitivity. However, without a compatibilizer, PET/PP blends exhibit weak interfacial adhesion and poor mechanical properties.

1. Colorfastness - Excellent lightfastness and weather resistance

2. Thermal stability - Temperature resistance exceeding processing temperatures by 20°C significantly impacts pricing tiers

3. Chromatic performance - Includes color brightness (L*) and hue angle (hab)

4. Tinctorial strength and dispersion characteristics

5. Migration resistance and water resistance

6. Chemical inertness - Acid/alkali resistance, ethanol tolerance, etc.

7. Minimal shrinkage and warpage effects

Today, a business delegation from Chongqing visited Rizhao Wanjia Plastic Products Co., Ltd. (hereinafter referred to as "Rizhao Wanjia") in Shandong for an inspection and exchange. The two parties reached an in-depth cooperation agreement on the production and market expansion of eco-friendly packaging products, including drawstring garbage bags, accordion-fold garbage bags, and food bags, and signed a strategic partnership agreement. This collaboration marks a new stage of industrial cooperation between Shandong and Chongqing in the field of sustainable materials, injecting fresh momentum into regional economic development.

U.S. chemical companies are facing shrinking margins due to fluctuating oil and gas prices, while dealing with tariffs and economic uncertainty, the Global Energy & Chemicals Industry Market Information Service said recently.

In order to meet the continuous growth of market demand for environmentally friendly packaging products, Rizhao Wanjia International SCM Co., Ltd. has recently launched the construction project of an intelligent warehouse center. The 1,000-square-meter modern warehouse is adjacent to the production workshop of rolling bags, dedicated to storing the raw materials and auxiliary materials for flat rolled plastic bags and undershirt rolled plastic bags, and is expected to be put into use in the fourth quarter of 2023. The project marks a key step in the company's strategy for capacity enhancement and sustainable development.
