Plastic tube, provided by cosmetic tube packaging suppliers, is one of the most common packaging containers made of LDPE, HDPE, pp...etc.

Products Description

The structures of empty cosmetic tubes are: Mono-layer, 2-layer, 3-layer and 5 layers. The diameter of cosmetic tube containers are about: 13, 13.5, 16, 17, 19, 22, 25, 30, 35, 38, 40, 45, 48, 50, 55, 60 for round tubes, and while for Oval Tube, they are 16, 19, 25, 30, 35, 40, 50. The volume of round plastic tube ranges 2-400ml, and oval tube ranges from 20ml to 180ml. The production flow of plastic tube is extrusion, heading, offset/silk scrren, hot stamping, cap injection, capping, packing, warehouse.

The mechanical performance of cosmetic tubes wholesale has below characteristics: impact resistance, puncture resistance, flexibility, tensile strength above 10Mpa, and chemical stablility which shows in below aspects:

1 .Plastic tube is resistant to water at room temperature

2. Plastic tube is resistant to most types of dilute acids.

3. Generally speaking, a cosmetic tube packaging is resistant to alcohols, aldehydes, ketones, and esters.

7. Plastic tube would crack under the influence of stress cracking agents, such as detergents, soaps, oils, fats, alkali metal hydroxides..etc.

8. Weather resistance: Under the action of ultraviolet light and high energy radiation, it will degrade in the air, discoloration, surface cracking or even embrittlement, which result in loss of strength or value of use. So in order to avoid above issue, weather resistant formula, ie adding UV absorber, light shielding agent, Or a light quencher..etc should be adopted. b), barrier: the excellent barrier to water vapor transmission, higher the density, stronger the barrier properties.

9. Hygenic performance: in accordance with food hygiene standards, non-toxic, tasteless, direct contact with cosmetics, foods, and medicines.

10. Molding properties: extrudability; easy heat sealing; good thermal stability, good fluidity, and excellent molding properties (can be used in any common plastic molding process).
