Mechanical properties of plastic tube for cosmetics:
Impact resistance, puncture resistance, flexibility, tensile strength are above 10MPa.
Chemical stability of cosmetic plastic tube packaging :
A. Not affected by water at normal temperature;
B, the majority of dilute acid resistance;
C. Generally not affected by alcohols, aldehydes, ketones and esters;
D. Less affected by halogens at room temperature;
E. Expansions are caused to a certain extent by the action of aromatic hydrocarbon, aliphatic hydrocarbon and halogen hydrocarbon at room temperature;
F. Slight absorption of oil, mineral oil, essential oil will be dissipated through polyethylene;
G. Stress cracking may occur under the action of stress cracking agent.
The common stress cracking agent is detergent, soap, oil, fat, alkali metal hydroxide and so on.
Cosmetic plastic squeeze tube weather resistance:
Under the action of ultraviolet and high-energy radiation, it will degrade in the air, resulting in discoloration, surface cracking and even embrittlement, loss of strength and loss of use value. The weather-resistant formula should be used, namely adding ultraviolet absorbent, light screen agent or light quenching agent, etc.
Cosmetic plastic tube resistance:
The higher the density, the stronger the barrier performance.
Hygienic properties of plastic tubes for cosmetics:
Comply with food hygiene standards.
Non-toxic, tasteless, direct contact with cosmetics, food, medicine.
Cosmetic plastic tube molding performance:
It can be extruded, easy to heat seal, good thermal stability, good fluidity and excellent molding performance (any common plastic molding processing method can be used).
The cosmetic tube packaging is easy to carry and can return to its original shape and maintain a good appearance even after high-intensity squeezing all over the body.
The quality of the cosmetic packaging directly determines the product brand image. Guangzhou Yello Packaging is targeted at the needs and standards of packaging products of different cosmetic packaging.
