What problems should be paid attention to when buying cosmetic packaging material hoses?

Many people do not know how to choose cosmetic packaging material hoses. There are many styles. So what should be paid attention to when purchasing cosmetic packaging material hoses? Let me introduce to you!

The wall thickness of the cosmetic packaging material hose is uniform, and the part where consumers can concentrate on it. The printing surface should be smooth and continuous; if the liquid cosmetic packaging material hose contains handles, grooves, ribs and other structures.

The printing surface of the cosmetic packaging material hose should be designed so as not to cause any inconvenience to the printing operation. The label surface should be flat. A “frame” can be designed on the outer surface of the cosmetic packaging material hose to make the label position accurately.

When the outer surface of the cosmetic packaging material hose adopts the label, it will not move, such as the middle part of the cosmetic packaging material hose is relatively thin. Changing the outer shape of the cosmetic packaging material hose and increasing the circumferential grooves or ribs on the outer surface of the cosmetic packaging material hose can improve the rigidity and bending resistance of the cosmetic packaging material hose. Longitudinal grooves or reinforcing ribs can eliminate the deviation, sagging or deformation of the cosmetic packaging material hose under temporary load; if the material is high-density polyethylene or polypropylene.

When designing an squeeze cosmetic packaging material hose, the cross section of the cosmetic packaging material hose should be rectangular or oval. For low-density polyethylene or other flexible cosmetic packaging material hoses, the cross-section should be round The shape is good, so that the contained objects can be easily squeezed out of the cosmetic packaging tube.

When blow molding, always tend to harden first. Therefore, the wall thickness of this part is also larger. The edge and corner part, the part where the parison is in contact with inflation, the wall thickness of this part is small.
