Polyethylene Tablet Bottle


Polyethylene can be divided into high-density polyethylene, low-density polyethylene and linear low-density polyethylene according to the polymerization method, molecular weight and chain structure. Low density polyethylene (LDPE) is commonly known as high-pressure polyethylene. Because of its low density and softest material, it is mainly used in plastic bags and agricultural films. High density polyethylene (HDPE), commonly known as low pressure polyethylene, has higher temperature resistance, oil resistance, steam penetration resistance and environmental stress cracking resistance than LDPE and LLDPE. In addition, it has good electrical insulation, impact resistance and cold resistance, and is mainly used in blow molding, injection molding and other fields. Linear low density polyethylene (LLDPE) α- A copolymer of olefins polymerized in the presence of a catalyst. LLDPE is similar to LDPE in appearance, with poor transparency, but good surface luster. It has the advantages of low temperature toughness, high modulus, bending resistance, stress cracking resistance, and good impact strength at low temperature.

High density polyethylene materials in polyethylene bottles are widely used in packaging containers for oral solid, capsule, tablet and other drugs. Low density polyethylene is mainly used for relatively soft packaging materials, such as eye drops bottles and infusion bags.

Polyethylene bottle refers to the medical plastic bottle produced with polyethylene as the main raw material. Polyethylene (PE for short) is a thermoplastic resin made from ethylene through polymerization. In industry, it also includes ethylene and a small amount of α- Copolymers of olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum use temperature can reach - 100~- 70 ° C), good chemical stability, and can withstand the corrosion of most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, with small water absorption and excellent electrical insulation.
