A Brief Talk on the Appearance and Process of the Packaging Material Tube of Medicinal Cosmetics

The aluminum ointment hose should have sufficient rigidity and beautiful appearance, can attract the user's eye in appearance, and ensure that consumers can have many choices and usability in use. The common shapes of ointment aluminum hoses are round, square, oval and so on. From the perspective of use, each has its own advantages and disadvantages. The round cosmetic packaging material hose has high rigidity, but its appearance is not beautiful. The square cosmetic packaging material hose is beautiful in appearance, but it is not easy to control the uniform wall thickness of the cosmetic packaging material hose during forming.

The ointment aluminum hose should be well controlled and designed in the production, made and produced in accordance with certain production and processing techniques, and has good performance and functions, and can fully demonstrate important in the industry value.

1) When designing an extruded ointment aluminum tube, if the material is high-density polyethylene or polypropylene, the cross-section of the cosmetic packaging tube should be rectangular or oval. Ethylene or other flexible cosmetic packaging material hoses should be round in cross section. This makes it easy for the contents to be squeezed out of the cosmetic packaging tube. The plastic parts used in conjunction with the hose port of the cosmetic packaging material are mainly caps and sealers. The design of the cosmetic packaging material hose mouth should be considered; how to make the cosmetic packaging material hose mouth better match the cover and sealer to the bottom of the cosmetic packaging material hose is the weak mechanical performance of the cosmetic packaging material hose Location. Therefore, the bottom of the aluminum ointment hose is generally designed to be concave; the corners and the inner recesses of the cosmetic packaging hose are all made with larger arcs. In order to facilitate the stacking of cosmetic packaging material hoses and increase the stacking stability of the cosmetic packaging material hoses, the bottom of the cosmetic packaging material hose should be designed with an inner groove.

2) When labeling is used on the surface of the aluminum tube of ointment, the labeling surface should be flat. A 'frame' can be designed on the surface of the cosmetic packaging material hose, so that the label can be positioned accurately without movement. In blow molding, the first part of the parison that is blown into contact always tends to harden first. Therefore, the wall thickness of this part is also larger. The edge and corner part is the contact part after the parison is inflated, and the wall thickness of this part is small. Therefore, the edges and corners of the cosmetic packaging material hose should be designed with rounded corners. Change the surface shape of the cosmetic packaging material hose. For example, the middle part of the cosmetic packaging material hose is relatively thinner, and increasing the circumferential grooves or ribs on the surface of the cosmetic packaging material hose can improve the rigidity and bending resistance of the cosmetic packaging material hose. . The longitudinal grooves or reinforcing ribs can eliminate the deviation, sagging or deformation of the cosmetic packaging material hose under long-term load.

3) Since most plastics are notched and sensitive, cosmetic packaging material hoses are prone to cracks and cracks at sharp corners, roots of mouth threads, necks, etc., so these parts should be designed to be round angle. For the transfer point of the rectangular cosmetic packaging material hose, it is necessary to support most of the load of the cosmetic packaging material hose. Therefore, locally increasing the wall thickness at this point is also beneficial to improve the rigidity and load resistance of the cosmetic packaging material hose.

4) The printed surface of the ointment aluminum tube is the place where consumers' attention is concentrated. The printing surface should be smooth and continuous; if the cosmetic packaging material hose contains handles, grooves, ribs and other structures, the design should be careful not to cause inconvenience to the printing operation. The oval-shaped cosmetic packaging material hose has higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the cosmetic packaging material hose, in addition to selecting high-rigidity materials, the appearance design of the cosmetic packaging material hose must be used to enhance the rigidity and load resistance of the ointment aluminum hose.
