What Are The Performance Requirements Of Cosmetic Soft Tube Packaging?



The main components of cosmetics are oil, water – soluble polymer compounds, surfactants and so on. In addition, solvent raw materials, fragrances, spices, dyes, pigments, preservatives, antioxidants, these components determine the inherent characteristics of cosmetics, but also put forward certain requirements for the flexible packaging of cosmetics, mainly as follows.

1. Beautiful appearance

Under normal circumstances, the tube body of cosmetic soft tube packaging should be complete, stable, upright, smooth, uniform thickness, no cold explosion, crack, obvious scars, deformation, etc.; Complete printing design, no printing defects; Hose inside and outside should be clean, no accessories

2. Function protection
And mildew, resulting in product quality decline, and water and oxygen are the main factors affecting microbial growth; Unsaturated bond in oil is easy to be oxidized, leading to cosmetic deterioration; It can be seen that anti-corrosion, anti-oxidation and anti-odor are the key points of preservation of cosmetics, as well as the important requirements of cosmetic soft tube packaging. Therefore, cosmeticsoft tube packaging must be immersed test, barrier test and seal test, in order to meet the requirements of cosmetics. Cosmetic soft tube packaging test item. The appearance of cosmetic soft tube packaging is mainly tested by visual inspection. The surface should be free of defects, and the printing color difference and overprint deviation should be within the allowable range. Screen printing or flexographic printing is a common printing method for cosmetic soft tube packaging, and it is necessary to detect ink adhesion. Here’s how:

(1) Thumb test method Test conditions: more than 5 samples. Test procedure: Take the sample, place your thumb on the printed pattern, and wipe it back and forth 15 times with 3+0.5/0KGF force. Experimental judgment: sample printing pattern shall not have notch, broken line, poor ink adhesion, otherwise it is unqualified. (2) Test methods of 810 adhesive tape Test conditions: more than 5 samples, adhesive tape. Experimental procedure: Paste the tape completely on the screen printing, then pull the tape quickly at a 45 degree Angle, and test three times in a row. Experimental judgment: the sample printing pattern shall not have gaps or broken lines, otherwise it is unqualified.

To sum up, contents protection is the main function of cosmetic soft tube packaging, which is divided into functional protection and mechanical protection. Among them, packaging materials anticorrosion, barrier and sealing. Seal belongs to functional protection, the shelf life of cosmetics is very important; Mechanical protection is to ensure that the hose will not be damaged or broken under the action of external forces, so as to ensure the safety of the cosmetics have been transported. The beautiful appearance of soft tube packaging will directly affect the sales of cosmetics. The main influencing factors include external printing effect and surface touch. Therefore, if we can fully understand and grasp the performance requirements of cosmetic soft tube packaging and related detection methods, we will greatly improve our ability to develop in this product field, so as to promote the development of cosmetic soft tube packaging industry to develop faster and better.
