nutritional supplement containers

PE health care products are made of polyethylene (PE) as the main raw material. The pure PE resin is a milky white waxy solid powder with good moisture resistance, and oxygen and some other gases can pass through. Polyethylene (PE) is insoluble in water, and is insoluble in other solvents at normal temperature. It is slightly honored toluene, acetic acid, etc. at 70 degrees or more.According to different polymerization conditions and structural properties, it can be divided into low density high pressure polyethylene (LDPE), medium density medium pressure polyethylene (MDPE), high density low pressure polyethylene (HDPE). Among them, HDPE nutritional supplement container is more widely used.

The physical properties of PE health care packaging bottles depend on the density of PE, which determines its basic properties such as hardness, moisture, water vapor permeability, stress cracking and transparency. When the density increases, the material becomes hard, the torsional denaturation and melting temperature increase, the permeability decreases, the high temperature resistance and low temperature resistance are good, and the resistance to stress cracking is weakened. Therefore, LDPE is less resistant to gases than HDPE and has lower tensile strength, but better toughness. Therefore, HDPE is widely used in the pharmaceutical industry for medicinal plastic bottles and health care products. LDPE is widely used as a film. package. Because PE is poisonous, it is a common material for pharmaceutical food packaging. The pharmaceutical packaging made of PE has good moisture and solvent resistance, and is not affected by strong acid and alkali, but its transparency is poor.
