About Cosmetic Packaging You Must Know Those Things

First, the basic requirements of the container and container supporting class

1.Bottle The bottle should be smooth, smooth surface, the bottle wall thickness is basically uniform, no obvious scars, deformation, there should be no cold burst and cracks. Bottle mouth should be square, smooth, no burr (burr mouth), thread, bayonet with the structure intact, square. The bottle and cover should be tight, no slippery teeth, loose, no leakage phenomenon. The bottle should be clean inside and outside.

2.Hose The body of the hose should be smooth, neat, uniform in thickness, no obvious scratches, and uniform in color. The sealing of the hose should be firm and square, there should be no openings and wrinkles (except for the normal indentation of the mold). The composite film of the hose should be free of floating phenomenon.

3.Lid The lid is divided into: PP material, ABS material, sarin material, PTCG material, K material, electrochemical aluminum, etc. Different materials are determined by touch sense, appearance, drop rebound sound and other experience, and disinfection methods are different. Inner lid: The inner lid should be complete, smooth, clean and not deformed. The inner lid should fit well with the bottle and outer lid. The inner lid should not leak. Outer cap: The outer cap should be square, smooth, without broken, cracked, burr (burr mouth). The color of the outer cap should be uniform and consistent.
