Tube knowledge

Today, the manufacturers of cosmetic plastic tubes will give you a little knowledge about cosmetic plastic tubes.

Mechanical properties of cosmetic plastic tube:

Impact resistance, puncture resistance, flexibility, and tensile strength above 10MPa. Chemical stability of cosmetic plastic tubes:

A. Not affected by water at room temperature;

B. Resistant to most dilute acids;

C.-Generally not affected by aldol, ketone and esters; D. Less affected by halogen at room temperature;

E. At room temperature, it will cause a certain degree of swelling due to the action of aromatic hydrocarbons, aliphatic hydrocarbons, and halogen hydrocarbons;

F. Slightly absorbs oil, mineral oil and essential oil will escape through polyethylene;

G. Stress cracking may occur under the action of stress cracking agent. Common stress cracking agents include detergents, soaps, oils, fats, alkali metal hydroxides and so on.

Weather resistance of cosmetic plastic tube:

Under the action of ultraviolet and high-energy radiation, it will degrade in the air, causing discoloration, surface cracking, even embrittlement, loss of strength and loss of use value. Weather-resistant formulas should be used, that is, UV absorbers, light shielding agents or light quenching Extinguishant, etc.

Barrier properties of cosmetic plastic tubes:

It has excellent barrier performance to the transmission of water vapor, the higher the density, the stronger the barrier performance.

Hygienic performance of cosmetic plastic tube:

Comply with food hygiene standards. It is non-toxic, tasteless, and can be directly contacted with cosmetics, food, and medicines.

Forming performance of cosmetic plastic tube:

Extrudable, easy to heat seal, good thermal stability, good fluidity, and excellent molding performance (any commonly used plastic molding processing method can be used).
