Need To Pay Attention To The Process Of Cosmetic Tube Labeling
Aug 12, 2019

The plastic parts used in conjunction with cosmetic nozzles are mainly caps and seals. The design of the cosmetic nozzle should be focused on; how to make the cosmetic nozzle better fit the lid and sealer with the bottom of the cosmetic tube is the weak part of the mechanical properties of the cosmetic tube. Therefore, the bottom of the cosmetic tube is generally designed to be concave; the corners of the cosmetic tube and the concave portion are excessively curved. In order to facilitate the stacking of the cosmetic tube, the stacking stability of the cosmetic tube is increased, and the bottom of the cosmetic tube should be designed with an inner groove.

When the surface of the cosmetic tube is marked, the surface of the label should be flat. A “sash” can be designed on the surface of the cosmetic tube to make the label accurately positioned without moving. At the time of blow molding, the portion where the parison inflates first contacts always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions where the parison inflates the last contact, and the wall thickness of the portion is small. Therefore, the edges and the corners of the cosmetic tube should be designed to be rounded. Changing the surface shape of the cosmetic tube, such as the middle portion of the cosmetic tube, is relatively thin, and increasing the circumferential groove or rib of the surface of the cosmetic tube can improve the rigidity and bending resistance of the cosmetic tube. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the cosmetic tube under long-term load.
