Typical Applications of Lotrene HDPE 5502

Food packaging containers. Lotrene HDPE 5502BN has excellent hygienic properties, low water absorption, and excellent stress crack resistance ensure the safety and quality of food during storage and transportation. It is widely used in the manufacture of various food packaging containers, such as cooking oil bottles, sauce bottles, and food storage boxes. It complies with relevant food contact safety standards and is suitable for direct food contact, providing a reliable packaging solution for the food industry.
Pharmaceutical packaging containers. The pharmaceutical industry places extremely stringent demands on packaging materials. HDPE 5502BN, with its stable chemical properties, high barrier properties, and excellent processing properties, meets the special requirements of pharmaceutical packaging. It can be used in medicine bottles, ointment tubes, and medical device packaging, effectively protecting drugs from environmental influences and ensuring their quality and efficacy.
Household and industrial chemical containers. Its high strength, impact resistance, and chemical resistance make it an ideal choice for household and industrial chemical containers. Common applications include laundry detergent bottles, dishwashing liquid bottles, and industrial chemical storage tanks. It can withstand chemical corrosion, maintaining container integrity during long-term storage and use, preventing chemical leakage and ensuring safe use.
Cooling equipment, such as ice buckets and coolers, requires materials with excellent rigidity and impact resistance to withstand the impact and friction of daily use. Lotrene 5502BN meets these requirements. Its low water absorption also ensures stable performance in humid environments, providing reliable material protection for cooling equipment and extending its service life.

Performance Characteristics

Excellent rigidity. Lotrene 5502BN enables blow-molded containers to remain lightweight while maintaining sufficient structural strength, effectively preventing deformation during use and ensuring product stability and durability. This superior rigidity makes it particularly suitable for containers requiring high shape retention, such as industrial chemical containers.
Excellent processability. HDPE 5502BN exhibits excellent processability during blow molding and can be easily adapted to a variety of standard blow molding equipment. The stable and easy-to-operate process efficiently produces high-quality, consistent products. This not only improves production efficiency but also reduces production costs, providing a strong foundation for large-scale production.
Outstanding stress crack resistance. 5502BN resin exhibits excellent resistance to environmental stress cracking, maintaining its integrity under high pressure and complex environmental conditions, and is not susceptible to cracking. This characteristic offers significant advantages in the manufacture of containers required for long-term storage or transportation of liquids, such as food packaging, bleach, and detergent containers, effectively extending the product’s lifespan and reducing the risk of leakage. High strength and impact resistance. This resin’s high density and strength allow it to absorb and dissipate impact forces, preventing container breakage. This excellent impact resistance ensures product safety during handling, storage, and use, reliably protecting contents even under harsh conditions.
Low water absorption. This product exhibits extremely low water absorption, meaning its physical and mechanical properties are not significantly affected by moisture absorption in humid or high-humidity environments. For products exposed to moisture or used in humid environments, such as outdoor cooling equipment and food and pharmaceutical packaging, Lotrene HDPE 5502BN consistently maintains stable performance, ensuring uncompromised product quality.
